You know what you're talking about. I figured my 36 volt charger needs a 200 watt supply. Can I afford the losses? The easiest & safest way is to use the charger it came with. A 42 volt 2 amp charger. Most of my riding is done with a peddle assist at 60 to 150 Watts or so. My 350 Watt motor is set for a 7 amp limit on a 15 amp controller. I'm good with the speed I get with a 30T chainring. When you say a 30 percent increase in range, that is pretty darn good. Thanks for the guide & introducing the Jackery.
How many watts of solar panels do I need to charge a e-bike that's 500w and the battery is 48v and the other e-bike is 1,000w and the battery is 48v.What will be the fastest way to charge e-bikes using solar panels ?
I charge my Sur Ron in the desert using a Montek 1000 and a Bluetti PV200. No I'm not trying to carry this stuff on my bike. I simply plug it in when I return to my campsite. Since the Montek has pass through charging it works well. And I bought both thanks to you Tom. Early adopter for the Montek and I also bought the solar ACOPower fridge/freezer due to you. So I run out of water or food while camping, but not power. Thank you.
"On the cheap." My favorite words. I'm looking for a sub-thousand dollar e-bike as strong as possible and a solar + wind generator that will run a couple of fridges and a freezer as cheaply as possible.
I've been charging my e-bike battery (along with my other power tool batteries) with my sogens since I got the bike 1.5 years ago. The price of a kW on our grid is $.05 winter and $.08 summer. So it costs me $.03 - $.05 to charge the larger 556Wh battery. The ROI of purchasing an expensive sogen to only charge your batteries is...forever However, if you already had the sogens, why not take advantage of them. What really would be great is if the bike batteries had pass through charging, i.e., you can use the bike while the sogen on the bike rack is also charging the battery. Could almost double my riding distance on a looong ride.
grid power is so cheap, it's really hard to compete with unless you are talking about a remote cabin that would cost millions to connect. but when the grid goes toes up they are sweeeeet. (Texas this winter, cough cough 🥶) I like the fact I can run my ebike as much as I want with no energy bill. I'm sure I'll spend more in tubes, tires, and chains over the long haul than energy though.
Incorrect, once the kw come to your home it all depends on how many ohms your homes grid has, over time it increases, after that it depends how efficient is the inverter and or chager you are using, furthermore heat disipation is a real thing. Energy is lost after your meter. In conclusion, you may pay for 1kw but your ebike battery will never be able to obtain that amount.
Great Job professor -you are still taking me to school. Perhaps you should have a chart for the newbies on watts amps and volts and hang it in the background....
My e-mtb E-CELLS brand bike has TWO batteries but the bike designer, here in Pahrump, Nevada, made patented frame plug for charging BOTH 52 V batteries simultaneously, greatly simplifying charging.
I use my diy solar power station to power my 60 volt scooter with 2100 watt hour battery. Takes 2 or 3 days to make enough energy to fully charge the scooter, but I don't ride the scooter every day anyway. I ride the kaabo wolf warrior electric scooter.
I don't use a silly jackery to charge my ebike All I have on my camping trips to charge ebike is 2 solar blankets 200w and a 80w, a ctkev300 mppt solar charge controller cheap from aliexpress and connections I made to connect battery and solar blankets to charger. Takes around 4 1/2hrs to charge my 52v 20ah battery from 43v to 58v .
Good video except no love for the jackerys 300,that's cold man. Also when I built my e-bike conversion I used 2 18volt power tool battery's to power and with how fat I'am I got 2 9.0amp batter's that take me anywhere but the makita quick charger is a bear running up my jackery up to 200 watts witch can only recharge one pack then pretty much dead jackery. Yet the theory is sound.
I have been charging my ebike with only solar power for over 2 years. A bit more then 10,000 miles…. The power comes from my bike trailer that has two 100watt flex solar cells with a battery box that inputs up to 130 watts from solar , holds 400wh and outputs up to 300watts 110v AC…. It will propel me up to 50 miles a day from the sun carting over 150lbs of camping stuff…. It’s all extremely reliable…
When I was kid at Germany, I had a 10 speed with a cool dynamo light powered by the ride, why not incorporate that into the self recharge. Change ratios to at least have a trickle charge while powered off. I don't know, just a thought.
They do make MPPT Boost charging units specifically for solar e-bike touring. Boosting the voltage is a much safer and more efficient way of charging. The racers' annual Sun Trip from France to China use such units and using your wall charger disqualifies you from the race! There are some knockoffs out there that work but are not trustworthy. You get what you pay for!
I have a Jackery 1000 and recently while using it when it hit 20% it started rapidly going down to zero like 1% per second before it hit zero and shut off. Any ideas what might be going on? The drain k was using was about 200 watts.
How about a cool efficient direct method. Charge two at once with a simple balancing resistor and an alternating tidal current from the smallest of solar panels?
I might have considered this if I could get the jackery for $100, but spending $200 will buy a bunch of battery cycles plugged into my home outlets. Not to mention the time spent hooking it up, changing solar panel angles and everything. I am not sure I could ever recoup that $200 before the jackery and ebike battery run out of cycles.
Thanks I bought my jackery 240 with your advice and I’m happy with the results but wondering if a 10 amp solar controller works with my 100 watt panel with the jackery or should I change anything
If electric bike batteries are generally standardized at specific voltages / amperages, why aren't there solar generators that specifically output charges that match those standards? It seems like a huge amount of energy is being wasted converting the DC output of the generator to AC so that chargers can immediately convert it back to DC. Personally, I think the solar generator industry needs to step up their game and build units with additional DC out options. This is one of the largest sources of energy inefficiency left. Anyone who's ever needed to charge their laptop from an external battery knows how silly this situation is.
My brother… the inverter is not the energy waster.. it’s the rectifier taking it to DC power. Touch the power brick you can feel it HOT my man. Great video.
I was looking to buy a boost charger to charge my ebike battery from solar directly. After seeing your video and the risks with that I will just use one of the portable power stations I have and use the charger that came with the bike to be safe. Thanks for another informative video.
Any suggestions on high wattage AC charging of portable power stations? For nomads it would be great to charge with free AC during a library visit. And if remote decreasing generator run time when the skies are cloudy could save a lot of gas.
I have a 240 to charge my ebike…the 240 fits in my pannier perfect…now all I need is a 65w solar panel that also fits in my pannier…better make it 100…I live in Canada
Think i can trust the BMS on ebike 48v batteries? Okay to charge at 60v5amp using solar directly? Also wonder how cool it would be to power the bike directly from a solar generator, some have a good space for it. I find it a lost opportunity that these bikes don't come with solar in, USB and low watt 110 inverter out.
@HOBOTECH Thanks for all of your very helpful vids! Do you have any experience with using, or seeing someone use, the “tarp-like” Solar Panels? Such as those offered by P3 Solar, PowerFilm, or the Off Grid Trek Solar Blanket?? Yep, I know, they are VERY expensive, relatively speaking. But on the plus side, they do offer light weight and a small size footprint when folded/stored, which is beneficial to backpackers or HAM radio operators in the field.
Are you serious? I could use my bluetti EB3A on my rear rack and plug my bosch battery charger to my Treak ebike which would extend the time or distance i can travel? Did i understand you well?
Thanks for your great info, I would like to get that blue adjustable battery charge , could please tell me where to get it and the model number,I have a 48volt battery on my ebike as well. Thanks again.
Question - I know enough about electricity to be dangerous, so: If my bike charger has a 42Vdc ---4A output that should mean ~168W draw from the Jackery/ other power station? The motor is a Shimano so 36V which is why I guess it can have a higher amperage with the 42Vdc draw?
i think there's a fare amount of people hung up on using the word "generator" because technically it isn't generating So power station is more accurate
you could have a power station w/o solar panels, recharged on grid power. got to throw the word "solar" in there to indicate it has that capability. strictly speaking it's the panel that's doing the generation, not the box.
They are the same thing in 2021. Solar generator is a marketing term used by many brands to describe the solar charging ability which "power banks" and older "power stations" don't have.
Mr. Hobo, do you think I could use something like this to charge the SLA battery on my Ezip TrailZ to extend its range too? Or would any battery backup at all do that? I haven't bought a battery yet but was thinking of getting something more like a 500w battery. So hopefully a little better than the Jackery you're showing here but that's about the best I could do, I'm poor if my E-Zip bike didn't give that away lol
@@HOBOTECH It has the included charger, would you think that could be charged while the bike is operating or would extended range mean that I'd need to stop and let the battery backup charge the bike batter while it's idol? I can tell you that the charge port on the battery for this model is different than the port that outputs power to the bike. That would seam like it would make it possible at least to have power coming in to the battery and out at the same time, but I'm not positive. Technology is great but can be frustrating!
Hey professor, a question off topic. What is the best solar power station solar panel package for sale today. Best bang for the buck so to speak.. thank you
I get asked this dozens of times a day so I guess I need to make a video. The best one for sale is a tie between the Bluetti AC300 or the Ecoflow Delta Pro. See my reviews.
Would you be able to charge two Jackerys at the same time off the same solar array? And if you could, would it be possible to add more panels (due to non-sunny days) than the recommended wattage and it not damage the jackerys? Ex: I have 2-100w renogy solar panels on my van roof- winter days I only get about 35-70watts. Could I add a third panel to boost the watts. If this is all possible I would totally just buy another Jackery and kind of hook the systems together.
You can't share a solar array. You need separate panels. You can over panel but you can't over volt. Stay within the Jackery voltage limit you can use as many panels as you want.
Hey Hobotech. Great video! Around the 5:30 mark you were talking about the advanced charger and were saying the adjustability is in the amps (how fast you charge the battery) and the percentage of charge. As far as the physical output of the charger what is the adjustability that does that % of charge function? Is it the voltage output? If so, what voltage would you charge you battery at to get it to just 80 or 90% ?
It's actually a good idea if you pop a jackery 240 240w or Golabs R300 300w or any other compact battery on the back it's like having a jerry can full of gas. So say you aren't paying attention and bombing around with one of those puppies in a backpack or something and suddenly look down and go "Oh oh, I'm down to 5% battery". Using one of these puppies may just give you enough juice to get home. If you can get an ultra compact 60w solar panel like an Aimtom 60w(sunpower cells) you could theoretically go on a little bike camping trip. While not the most effecient way of doing things, if you're camped for a couple of days. You could still top off the bike and the jackery and get home. Hey if you can get one of those bike trailers for carrying kids why not put a Bluetti 220P or 500 in it? Then you could drive yourself to Florida for the winter. You could still have room for a couple of 120w folding solar panels. Hell maybe you could rig the trailer up with solar to charge the Bluetti at the same time you're driving it.
my ebike uses about 10A @ 48V when cruising, or about 500w. that's a lot of panels to tow around on a bike. On the other hand, a solar boat could work nicely on a sunny day (Peter Sripol made a nice one) It's a lot of bucks but a second e-bike battery would weight about the same as the little jackery with a lot more energy onboard. you could also leave your second battery home charging...
I'm a complete water head with this stuff. When he says strap the Jackery on the back of the bike-- does that mean plug it into the battery and go or sit and wait for it to charge and then go?? Thanks
@@hmork460 I think he means strap to the rack and charge while you're on the road. you should verify that your bike will allow charging while riding, some may not. on any ebike you could stop for a break and charge back up.
I mean both or either. My DIY bike lets me charge while I ride. The other does not. You could essentially get to your destination or take lunch and let it recharge for the return trip.
@@HOBOTECH I saw an ebike battery pack that had a solar charge controller built into the bms. Is that type of setup ready to take power directly from a solar panel. I don’t recall where I saw it otherwise I would look for myself. This was not using usb c BTW. Thanks. 🙂
I need a Jackery or similar unit that will keep a small fridge charged. Which fridge? I haven't figured that out yet either, but I need the smallest solar generator possible that will keep a SMALL fridge/freezer running for a minimum of overnight, and preferably for at least 24 hours. If anyone has any experience to share that might help, I would be most grateful. I've watched every Hobotech video available on the matter, and I'm left confused. (That's not on Tom - it's on me. But still - I'm confused.) I just wanna buy the least expensive setup possible that will allow me to use my old Roadtrek with a fridge. (The original fridge doesn't work well so it's a pantry now.) Thanks in advance for any advance. I'd love to take advantage of the Jackery sale!
I have BougeRV 53 qt. It draws 60-65 watts After its zero (0° setpoint) on DC cable input to it. I hooked up to eb240 no issues for 12-16 hrs between sunlight to charge. Ran for three months in test. Compressor not a 100% duty cycle mho. More like a few days. Butt will run months. Needs switching to AC. Plugged in AC After its cold (0°) oops all F°, on AC its on off about 50/50. Draws about 70 watts per hour to 100 sometimes. Air in house depends, house warmer more power. Sooo. I use Ice King now at 120 vac draws about 140 watts at -2F° butt surge start is 1500 watts. Runs off AC200p. The answer; plug dc out (of eb240) 12 vdc to AC200p input set at low dc. For about 6 pm dark to midnight adds 650 watts to other. Five cubic feet freezer acrticking vs bougerv 1/4 size. Newer 200max soon arrives. Hint end of video; winter lucky if 6 hours of full sun now. Over panel to max inputs. Array to eb240 gets eo17,(over volt) I just fold panel over one to cut input volts then flip it back over. This gives me 500 watts in to recharge eb240 in 4 hours max. Or throw blankets over two panels ( used 170 bougerv four series parallel see his video on how to wite).
You can watch my many fridge reviews to get that answer. Most smaller fridges under 40qt will use about 250wh/day at 40F assuming ambient around 70-80F. So a Jackery 300 would be the smallest if you want to guarantee 24 hours.
@@ancientbutstillhere6570 Thanks so much for contributing your experience. Real-world experience is very helpful to those of us making plans and trying to sort out where and how to spend our (little bit of available) money most productively.
Hi 👍 I've been looking for someone for a long time to help me realize my dream. My solar mtb trip with my dog. The trailer I created it in ergal and or finally an assisted motor BBSHD 1000wat Bafang with a battery 52v.28ah.1460Wh
@The Tired Horizon I love my Insta pot too. Cooks meat stews, dried beans, lentils etc. super fast and delicious. It doesn't do good however with starchy potatoes or pasta as it creates a steamy bubbly mess. Any tips?
instant pots are neat. they do however have a large peak power, so you'll need a pretty big inverter/battery combo to run them. crock pots have a really low & constant power (75w low, 150w high is typical). they can be run from a very modest inverter. Once the instant pot heats up the duty cycle is low. Their total power consumption can actually be less than the crock pot, since the instant pot will cook in 30 minutes what takes the crock pot 6 hours.
@@HOBOTECH I checked with lectric one of the most popular Ebikes and they said no charging while riding on their model. Based on that model I don't see the need to have a model to strap to the bike and would likely just have a larger battery. With a pure sine wave. Great video though
Of course. I think the point was it would be easier to carry a second bike battery, charged at home by solar, then in the extreme case trailer a Jack 1000 and a couple of panels.
You missed the point completely. Your talking amature hr. We riders going into the wilderness for days not hours we also need to charge our other devices. I use a mppt that is programmable so dont need a power station. Its also less wasteful from waste heat and other losses. Use a 60watt DC to DC. Just need to recover 2-6mi. Also have my 6amp 300watt array or use in combo and get 360w. Mor than needed on a clear day. But on a cloudy day that extra 60watts helps. The including an inverter to convert it into AC then back to DC is just effort. It seems very odd he dint think of this more stream line solution. You can also charge usb devices.
@The Tired Horizon a pellet stove uses electricity to turn the pellet auger, and has a control system to maintain the temperature by varying the fuel consumption rate. They also have an electric element to start the fire. A quick web search says 130w to run and 430w for ignition. that doesn't really tell you how many kWh it will draw in a day. but just guessing a 100w panel wouldn't be enough for reliable use in the dead of winter when you have little sun and run the pellet stove a lot. If you don't have room or money for a larger solar system maybe stick with a good old wood stove.
@@RealJohnnyDingo I would buy a good old wood stove, (which I did when I was 20 years younger and it was great). But now, 70 years old and a really bad, arthritic back, this man knows his limitations. The pellet stove with solar power is my next best choice, I think.
@@avlisk they seem really convenient, no chopping wood required. it's probably better to buy a little bigger solar system than you think you really need, extra capacity is a good buffer for those cold, sunless days.
@@RealJohnnyDingo Yes, the splitting and stacking just got to be more than I could handle. But I like wood heat so much, the pellet stove seemed the best alternative. I have a small solar setup already in my little van. I just ordered a second BattleBorn 100Ah battery. I now have 200w and 2 batteries, so I'll try using that.
I have an idea, make a rack to mount on the back of your bike, strap on a 200 watt solar panel, connect the bike battery to it so that while you are riding, it will keep your battery charged. what about having a generator crank out some power that when you are riding it can put some juice back into the battery? (I am still a believer in "Perpetual motion" - it's got to be real, doesn't it?) When are these electric cars going to put photovoltaic cells on the roofs of their cars to charge their batteries? Back in the 1980's Ford had a Prototype Probe car that had these and they seemed to work well - what happened? Why is this not happening? Are the battery companies against this? Sort of like the gas companies do not want us running cars from water.
If solar panels charge the Jackery battery safely, then what makes it different from putting solar panels with the right regulator into the e-bike battery. After all both are batteries.
Is it not possible to connect solar panels directly to the bike's battery using a solar charge controller and not using a generator w/ AC inverter? That is truly what I was expecting this video to be about based on the title.
@@HOBOTECH Uh, It's a 48 volt battery(mine's 36V). 48 volt solar charge controllers exist, and you know that. Maybe not for this battery tech? It seems a charge profile adjustment would solve that. Or not? It is what I was looking for answers for, hence my initial comment. Why the unnecessary shade? I am asking a valid question about something that should be able to be done...at least since all the components to do so exist. As I stated before, that is what your title alluded to. Maybe I have the wrong channel. All I know is that charging one battery from another that had to be charged from another source(solar) is not a viable real world solution. I need THAT battery to run things instead of charging a bike battery. Wouldn't it be cool to actually charge your bike's battery directly with solar panels?
So the short answer, for those without time to watch, is to plug your bike charger into your solar generator! Next week hobo shows how to charge your electric bike from home AC power!

Any suggestions on high wattage AC charging of portable power stations? For nomads it would be great to charge with free AC during a library visit. And if remote decreasing generator run time when the skies are cloudy could save a lot of gas.
Nice video, thank you😊
Hobo tech. do a video on rechargeable AA and AAA Li Ion. Batteries and chargers.
Test XTAR , i just bought one to charge 1.5V lithium and 1.2V NIMH
massive help thanks for the info
I have a 240 to charge my ebike…the 240 fits in my pannier perfect…now all I need is a 65w solar panel that also fits in my pannier…better make it 100…I live in Canada
Think i can trust the BMS on ebike 48v batteries? Okay to charge at 60v5amp using solar directly? Also wonder how cool it would be to power the bike directly from a solar generator, some have a good space for it. I find it a lost opportunity that these bikes don't come with solar in, USB and low watt 110 inverter out.
@HOBOTECH Thanks for all of your very helpful vids! Do you have any experience with using, or seeing someone use, the “tarp-like” Solar Panels? Such as those offered by P3 Solar, PowerFilm, or the Off Grid Trek Solar Blanket?? Yep, I know, they are VERY expensive, relatively speaking. But on the plus side, they do offer light weight and a small size footprint when folded/stored, which is beneficial to backpackers or HAM radio operators in the field.
Thank you! And very funny. I enjoyed your jokes immensely.
Are you serious? I could use my bluetti EB3A on my rear rack and plug my bosch battery charger to my Treak ebike which would extend the time or distance i can travel? Did i understand you well?
Should you drop ankor and charge your lithium batteries or get solar sails
Just checked out your online store, very cool.
Great value, and comfortable to ride
So the sinch? Adventon will it charge a well sinch is 750 but it's lime that model 750w 48v 12.8 a it will harge that?
Thanks for your great info, I would like to get that blue adjustable battery charge , could please tell me where to get it and the model number,I have a 48volt battery on my ebike as well. Thanks again.
Question - I know enough about electricity to be dangerous, so:
If my bike charger has a 42Vdc ---4A output that should mean ~168W draw from the Jackery/ other power station?
The motor is a Shimano so 36V which is why I guess it can have a higher amperage with the 42Vdc draw?
Please do a review on the new generator WATTFUN 300. I hear they are giving the Jackery a run for its money!
If my bike battery has to be switched on to charge, can I charge it while I use it, with solar, or some spare batteries I have fixed to the pannier?
Goodmorning Professor Hobo
So for jackery 500 too charge 48v 5a do I need 600w panels.What panels are best for jackery
The flow rate of electric charge seems a necessary condition to know if a person is to circumnavigate the globe with a solar bike.
What is the difference between a power station and solar generator?
i think there's a fare amount of people hung up on using the word "generator" because technically it isn't generating So power station is more accurate
@@carolmaplesden916 Thanks. So they are the same thing like 6 to 1 and 5 + 1 to the other (just want to prove I know my advanced math 😃).
@@davidpatrick1813 right on thats cool yes just like that 6 to 1 or 5+1 LOL 🙂
you could have a power station w/o solar panels, recharged on grid power. got to throw the word "solar" in there to indicate it has that capability. strictly speaking it's the panel that's doing the generation, not the box.
They are the same thing in 2021. Solar generator is a marketing term used by many brands to describe the solar charging ability which "power banks" and older "power stations" don't have.
Thanks Tom! I'm hoping for blue skies too!
I am new. To eBay king and have a lot to learn. I want to bite camp and maybe eventually do coast to coast on an ebay can it be done is it possible
Mr. Hobo, do you think I could use something like this to charge the SLA battery on my Ezip TrailZ to extend its range too? Or would any battery backup at all do that? I haven't bought a battery yet but was thinking of getting something more like a 500w battery. So hopefully a little better than the Jackery you're showing here but that's about the best I could do, I'm poor if my E-Zip bike didn't give that away lol
If your SLA battery has a charger, yes.
@@HOBOTECH It has the included charger, would you think that could be charged while the bike is operating or would extended range mean that I'd need to stop and let the battery backup charge the bike batter while it's idol? I can tell you that the charge port on the battery for this model is different than the port that outputs power to the bike. That would seam like it would make it possible at least to have power coming in to the battery and out at the same time, but I'm not positive. Technology is great but can be frustrating!
FYI - I Ihave a non big buck $1400 52V folding fat tire bike by Driven out of Costa Mesa, CA.
oh wow
Hey professor, a question off topic.
What is the best solar power station solar panel package for sale today. Best bang for the buck so to speak.. thank you
I get asked this dozens of times a day so I guess I need to make a video. The best one for sale is a tie between the Bluetti AC300 or the Ecoflow Delta Pro. See my reviews.
This is the video we needed! Do u think I could use a 4a ebike quick charger with the golabs 300w inverter
Probably.
I would like to do dc to dc rather than lose the to conversion and the processes inefficiencies
You don't need a jackery or a charger to do that. Just a boost converter
Would you be able to charge two Jackerys at the same time off the same solar array? And if you could, would it be possible to add more panels (due to non-sunny days) than the recommended wattage and it not damage the jackerys? Ex: I have 2-100w renogy solar panels on my van roof- winter days I only get about 35-70watts. Could I add a third panel to boost the watts. If this is all possible I would totally just buy another Jackery and kind of hook the systems together.
You can't share a solar array. You need separate panels. You can over panel but you can't over volt. Stay within the Jackery voltage limit you can use as many panels as you want.
Was the sale only on that day?
The sale is through the 20th as said in the video.
Hey Hobotech. Great video! Around the 5:30 mark you were talking about the advanced charger and were saying the adjustability is in the amps (how fast you charge the battery) and the percentage of charge. As far as the physical output of the charger what is the adjustability that does that % of charge function? Is it the voltage output? If so, what voltage would you charge you battery at to get it to just 80 or 90% ?
Jackery is da bomb!
Bluetti is the bomb.
Ecoflow is the best if you ask me. Can charge from 0% to 80% in an hour...or to 100% in an hour and a half.
I thought you said 50% off sale and almost had a heart attack that I missed it…LOL.
Will you review the new EB120. Pleeeeease
It's actually a good idea if you pop a jackery 240 240w or Golabs R300 300w or any other compact battery on the back it's like having a jerry can full of gas. So say you aren't paying attention and bombing around with one of those puppies in a backpack or something and suddenly look down and go "Oh oh, I'm down to 5% battery". Using one of these puppies may just give you enough juice to get home. If you can get an ultra compact 60w solar panel like an Aimtom 60w(sunpower cells) you could theoretically go on a little bike camping trip. While not the most effecient way of doing things, if you're camped for a couple of days. You could still top off the bike and the jackery and get home. Hey if you can get one of those bike trailers for carrying kids why not put a Bluetti 220P or 500 in it? Then you could drive yourself to Florida for the winter. You could still have room for a couple of 120w folding solar panels. Hell maybe you could rig the trailer up with solar to charge the Bluetti at the same time you're driving it.
my ebike uses about 10A @ 48V when cruising, or about 500w. that's a lot of panels to tow around on a bike. On the other hand, a solar boat could work nicely on a sunny day (Peter Sripol made a nice one) It's a lot of bucks but a second e-bike battery would weight about the same as the little jackery with a lot more energy onboard. you could also leave your second battery home charging...
I'm a complete water head with this stuff. When he says strap the Jackery on the back of the bike-- does that mean plug it into the battery and go or sit and wait for it to charge and then go?? Thanks
@@hmork460 I think he means strap to the rack and charge while you're on the road. you should verify that your bike will allow charging while riding, some may not. on any ebike you could stop for a break and charge back up.
@@hmork460 No when you run out of juice you can sit by the side of the road and charge up the battery. Think of it like a jerry can full of gas.
I mean both or either. My DIY bike lets me charge while I ride. The other does not. You could essentially get to your destination or take lunch and let it recharge for the return trip.
What if you have a usb c pd port on you panel and on your battery pack. Is it any safer to charge directly from solar with that type of setup?🤷
PD can only do 20v and won't work for batteries.
@@HOBOTECH Ok, thanks!🙂
@@HOBOTECH I saw an ebike battery pack that had a solar charge controller built into the bms. Is that type of setup ready to take power directly from a solar panel. I don’t recall where I saw it otherwise I would look for myself. This was not using usb c BTW. Thanks. 🙂
I was hoping to see you charge with PowerBens. ;-)
That's actually a good idea. I could do that with two in series. Not really the most cost effective solution though.
I need a Jackery or similar unit that will keep a small fridge charged. Which fridge? I haven't figured that out yet either, but I need the smallest solar generator possible that will keep a SMALL fridge/freezer running for a minimum of overnight, and preferably for at least 24 hours.
If anyone has any experience to share that might help, I would be most grateful. I've watched every Hobotech video available on the matter, and I'm left confused. (That's not on Tom - it's on me. But still - I'm confused.) I just wanna buy the least expensive setup possible that will allow me to use my old Roadtrek with a fridge. (The original fridge doesn't work well so it's a pantry now.)
Thanks in advance for any advance. I'd love to take advantage of the Jackery sale!
great question i would like to know also!
@@cavemancamping Thank you, Sir. Very kind of you to reply with your experience. Very helpful.
I have BougeRV 53 qt. It draws 60-65 watts After its zero (0° setpoint) on DC cable input to it. I hooked up to eb240 no issues for 12-16 hrs between sunlight to charge. Ran for three months in test. Compressor not a 100% duty cycle mho. More like a few days. Butt will run months. Needs switching to AC. Plugged in AC After its cold (0°) oops all F°, on AC its on off about 50/50. Draws about 70 watts per hour to 100 sometimes. Air in house depends, house warmer more power. Sooo. I use Ice King now at 120 vac draws about 140 watts at -2F° butt surge start is 1500 watts. Runs off AC200p. The answer; plug dc out (of eb240) 12 vdc to AC200p input set at low dc. For about 6 pm dark to midnight adds 650 watts to other. Five cubic feet freezer acrticking vs bougerv 1/4 size.
Newer 200max soon arrives. Hint end of video; winter lucky if 6 hours of full sun now. Over panel to max inputs. Array to eb240 gets eo17,(over volt) I just fold panel over one to cut input volts then flip it back over. This gives me 500 watts in to recharge eb240 in 4 hours max. Or throw blankets over two panels ( used 170 bougerv four series parallel see his video on how to wite).
You can watch my many fridge reviews to get that answer. Most smaller fridges under 40qt will use about 250wh/day at 40F assuming ambient around 70-80F. So a Jackery 300 would be the smallest if you want to guarantee 24 hours.
@@ancientbutstillhere6570 Thanks so much for contributing your experience. Real-world experience is very helpful to those of us making plans and trying to sort out where and how to spend our (little bit of available) money most productively.
Interesting… adjustable charger which brand
That looks like the Luna charger.
Yes it is a Luna.
Still need to take ya batteries to 100% sometimes to balance the cells unless you set the bms to balance at 80%
I do this before a long ride.
Hi 👍 I've been looking for someone for a long time to help me realize my dream. My solar mtb trip with my dog. The trailer I created it in ergal and or finally an assisted motor BBSHD 1000wat Bafang with a battery 52v.28ah.1460Wh
I had to look up what a ‘instant pot’ is.
Never heard of them.
I like food more than bikes.
@The Tired Horizon I love my Insta pot too. Cooks meat stews, dried beans, lentils etc. super fast and delicious. It doesn't do good however with starchy potatoes or pasta as it creates a steamy bubbly mess. Any tips?
instant pots are neat. they do however have a large peak power, so you'll need a pretty big inverter/battery combo to run them. crock pots have a really low & constant power (75w low, 150w high is typical). they can be run from a very modest inverter. Once the instant pot heats up the duty cycle is low. Their total power consumption can actually be less than the crock pot, since the instant pot will cook in 30 minutes what takes the crock pot 6 hours.
@@cavemancamping Thank you. I'll try that.
Why not have a solar directly charging bike?
Instead charging a battery pack? Might as well have a fully charged second battery on hand.
Can you charge the bike while you are driving it?
Depends on the bike.
@@HOBOTECH I checked with lectric one of the most popular Ebikes and they said no charging while riding on their model. Based on that model I don't see the need to have a model to strap to the bike and would likely just have a larger battery. With a pure sine wave. Great video though
When does it start to make sense to just purchase a second bike battery?
This video is about solar charging and not extending range.
Of course. I think the point was it would be easier to carry a second bike battery, charged at home by solar, then in the extreme case trailer a Jack 1000 and a couple of panels.
Why not just pack another battery if more range is desired, rather than the inherent losses in a packaged inverter???
Yes 👍 ⚡🔋
Wahoo
The easiest way to go further is simple, just buy another bike battery and fix it to your rack.
You missed the point completely. Your talking amature hr.
We riders going into the wilderness for days not hours we also need to charge our other devices.
I use a mppt that is programmable so dont need a power station. Its also less wasteful from waste heat and other losses.
Use a 60watt DC to DC. Just need to recover 2-6mi.
Also have my 6amp 300watt array or use in combo and get 360w. Mor than needed on a clear day. But on a cloudy day that extra 60watts helps.
The including an inverter to convert it into AC then back to DC is just effort. It seems very odd he dint think of this more stream line solution.
You can also charge usb devices.
Here's one you probably haven't had asked before: Can one power a pellet stove with a 100 watt panel?
@The Tired Horizon a pellet stove uses electricity to turn the pellet auger, and has a control system to maintain the temperature by varying the fuel consumption rate. They also have an electric element to start the fire. A quick web search says 130w to run and 430w for ignition. that doesn't really tell you how many kWh it will draw in a day. but just guessing a 100w panel wouldn't be enough for reliable use in the dead of winter when you have little sun and run the pellet stove a lot. If you don't have room or money for a larger solar system maybe stick with a good old wood stove.
@@RealJohnnyDingo I would buy a good old wood stove, (which I did when I was 20 years younger and it was great). But now, 70 years old and a really bad, arthritic back, this man knows his limitations. The pellet stove with solar power is my next best choice, I think.
@@avlisk they seem really convenient, no chopping wood required. it's probably better to buy a little bigger solar system than you think you really need, extra capacity is a good buffer for those cold, sunless days.
@@RealJohnnyDingo Yes, the splitting and stacking just got to be more than I could handle. But I like wood heat so much, the pellet stove seemed the best alternative. I have a small solar setup already in my little van. I just ordered a second BattleBorn 100Ah battery. I now have 200w and 2 batteries, so I'll try using that.
Yes, I have run my Trager off a Jackery 300. Haven't tried it with anything smaller.
cool my 300watt battery would work
Love how people would call that battery box a "Solar Generator" 🌞
Make a video on your bike
I have multiple videos on my bikes.
I have an idea, make a rack to mount on the back of your bike, strap on a 200 watt solar panel, connect the bike battery to it so that while you are riding, it will keep your battery charged.
what about having a generator crank out some power that when you are riding it can put some juice back into the battery? (I am still a believer in "Perpetual motion" - it's got to be real, doesn't it?)
When are these electric cars going to put photovoltaic cells on the roofs of their cars to charge their batteries? Back in the 1980's Ford had a Prototype Probe car that had these and they seemed to work well - what happened? Why is this not happening? Are the battery companies against this? Sort of like the gas companies do not want us running cars from water.
You can't charge a bike battery direct with a solar panel with out a very expensive controller. Besides ... ever heard of "wind resistance"?
@@HOBOTECH LOL, Dang, I thought I was onto something...Onto my desk drawing board.....
If solar panels charge the Jackery battery safely, then what makes it different from putting solar panels with the right regulator into the e-bike battery. After all both are batteries.
All e bikes are from China, even name brands, they buy them up in bulk, put their name on it and up the price.
So it was jackery long long advertisement:((
Review for CPAP Users
drat they are sold out of their 200w solar panels! ugh
Go V
Gas just hit $6 where I live and diesel is almost $7 ($6.59). I think this is on my shopping list.
Will it charge my Tesla Car ?
for that extra .01 miles of range? 😁
Is it not possible to connect solar panels directly to the bike's battery using a solar charge controller and not using a generator w/ AC inverter? That is truly what I was expecting this video to be about based on the title.
Find me a solar charge controller that works universally with 48v+ batteries and I'll look into it.
@@HOBOTECH Uh, It's a 48 volt battery(mine's 36V). 48 volt solar charge controllers exist, and you know that. Maybe not for this battery tech? It seems a charge profile adjustment would solve that. Or not? It is what I was looking for answers for, hence my initial comment. Why the unnecessary shade? I am asking a valid question about something that should be able to be done...at least since all the components to do so exist. As I stated before, that is what your title alluded to. Maybe I have the wrong channel. All I know is that charging one battery from another that had to be charged from another source(solar) is not a viable real world solution. I need THAT battery to run things instead of charging a bike battery. Wouldn't it be cool to actually charge your bike's battery directly with solar panels?
So the short answer, for those without time to watch, is to plug your bike charger into your solar generator! Next week hobo shows how to charge your electric bike from home AC power!
