It would be cool if Tesla had a reverse charging cable that connects from a Model X to the Model 3.
Your battery pack isn't a pure sine wave thats why it says its faulty.

I wonder if there is or if it's possible to get a battery share, like another car stops by you and shares a small percentage of his battery so that you can get that small range! That would be a good way to solve the problem
Francisco Caetano da Silva not really cuz not everybody has Tesla. So they might be waiting for a while.
Francisco Caetano da Silva there is a way to take some of the power from another Tesla but you would have to take out the stuff in the frunk and it is a pain to do
Did you take this from phones since phones can charge other wireless devices but good idea buddy!
Tesla should definitely make that an option and an electric share app would be good.
That's exactly what I was going to say
Super interesting test!
are you planning to buy the roadster 2020?
Jerry do some maths and make some thing with the help of linus techtips. Bestovluck
indeed m8 i thought it would work because power is power
Probably they should buy a small power generator.. and aslo its may be fit on Frank.
May be they will make a power bank for cars in the shape of a gas can
Will they?
Try with Dewalt portable power station. I gives 1800w continuous and 3600w peak so I think it will work.
Yes I've seen it work with the Goal Zero 1000 or 3000 Watt lithium battery it's because the units has 1500 watt continuous 3000 watts peak. It gives you enough amperage to charge your Tesla.
I agree try a larger battery pack and ensure the pack is grounded, I think that was the main reason the vehicles didnt accept a charge.
Remember the woman who tried to gas a Tesla?
@@trg3625 the guy's laugh was genuine tho
That was the best
🤣🤣🤣 I watched that video right before this one
@@foolietv1994 Lol
Wait I just saw that
That battery pack they're using has a modified sine wave he needs a pure sine inverter connected to a battery pack I made one for mine works great
The power inverted in the anker power bank was only a 200 watt inverter. You can charge ur Tesla off of a battery. But you need at least a 1500 watt inverter
The non-bonded ground was probably adding to the fault... A better choice would be a small inverter portable generator. ruclips.net/video/Nf6WgQfL7DY/видео.html
Get a bigger charcher🤖🤖🤖🤖🤖
Use 8 ankers
@@FromGregg or try it with the juice booster charger. It has a ground connection false check
neat idea, a solar charge controller and a few panels, the flexible kind would be easy to transport in the trunk, for portable solar charging when parked somewhere for food perhaps. a.co/d/2ahNDlp and a MPPT type charge controller.
Adding charging from another Tesla vehicle feature should be good solution.
Wouldn't be all that difficult to do, military vehicles have slave cables and ports specifically designed for jump starting so you're not even messing around with the standard leads
i strongly agree or have a pull-mode where another electric vehicle can pull you with the regenerate brake features disabled
could have a feature in the app to summon fellow tesla drivers with an incentive system provided in the app, free charging credits for example.
While I like the idea in order to start another vehicle, I do wonder if it can be exploited as gas thieves do.
Pin protected "jump cables" to transfer charge between Tesla vehicles! I'm surprised I don't see this feature being asked/twitted to Elon! :) . The Tesla owners community is awsome. Just like a Land Rover would come to help your Landy stuck in the middle of nowhere, I'm sure a Tesla fellow owner wouldn't mind coming to help you.
Tesla should put solar panels built into the car on the roof
Would take weeks to charge that way... not enough watt/hr to make it worth anything.
Yea or build your own if possible? Don’t have too pay for Electric no more
Daniel Pierce elon is thinking of making battery pack walls so that when you use solar panels at home your walls saves the energy
And windmills on the sides
A few weeks ago, on the red light got a short intro by a driver of FiskerInc Hybrid. It had a glass roof 200W solar panel. Not very much but, according to him, it helps to keep the car cool when parked outside in the summer, keeps air conditioning working.
I don't think the amount of power in the battery pack is the problem. When I started my research for my first Tesla I had a apartment garage that had no power save for the light bulb. The only way to charge while in the garage would be to plug into the bulb socket using a plug adapter. Problem is, those adapters are only 2 prongs because light sockets do not have a grounding connection. While researching the mobile charger manual, I discovered that the charger will always give a red light if it does not detect a ground connection. That means if you are plugged into a three prong and the ground connection does connect to anything, it will always be red.
Yes, the battery pack has the ground prong but it does not have an actual ground wire. The only way a battery pack like that could work would be if it allowed for a grounding wire to be connected to the pack and you connect said grounding wire to a grounding pole. A ground pole is basically a metal rod that is staked in the ground. Large generators come with copper rods to act as the grounding rod. A metal fence post might work as a grounding rod depending on how deep it goes.
Thanks Adam. You are the only person that decide to educate the viewers with your knowledge,
The problem might be that the power pack is a "modified sine wave" i.e square wave and AC power needed to charge the car is a sinusoidal wave, you would have to find out if your power pack is a pure sine wave or a modified sine wave.
No the problem was that the battery pack wasn't grounded.
Lol, you could use a gas power generator to charge a Tesla. Edit: seriously WhatsInside, use a gas can to charge your Tesla 😂
Kelly Silveira good idea
inverter generator will do. Someone did a video on this
Thats why we've got the BMW I3 in the UK
Then it becomes a gas car😂😂😂 so forget the tesla and buy BMW👍👍👍🤣🤣🤣
Kelly Silveira any links to the gas power generator? It runs off butane cans?
here in berlin, germany you can order a charging service, they come by bike with a big battery pack and charge your electric vehicle anywhere. just check out: chargery.de
Dan iel like the grand tour’s highway petrol solution
Awesome!!
Cool
who the heck runs out of battery in germany,,,,theres superchargers everywhere
that would take like over an hour, not much cheaper than a tow is it
Richard Roberson : car sharing companies use it for example. here are a couple of car sharing companies, which use also electric cars, you have an app, search for cars in your area, rent one, go where you wanna go and then just park it and leave it. you pay by km driven or by time. you get free minutes/km for filling up gas or pluging in charge stations. sometimes these cars run out of battery and then the charging bike is ordered...
Need a ground fault bypass cord by connecting the neutral and ground together.
thats what i have been saying
A lady already tried filling gas into a Tesla .. who SAW that 😂
shivankit ss where?
@@quarans08 ruclips.net/video/vHPg2Mi2roI/видео.html
This video
shivankit ss lmao i just watched it earlier this day
I just now watched that video XD
shivankit ss I did😆😆😆
some possible solutions that others have mentioned in the comments:::
1. battery sharing between two electric vehicles
2. gas generator which could power an electric vehicle,
3. small emergency/secondary battery with range of about 10-15miles, (like old motorcycle use to have a secondary tank/reserve for a few miles.)
4. ultra capacitor 'battery'
5. solar panels on the roof/hood/trunk.. (I am sure charge from panels that day could have gotten him 0.4 miles to the charge station.)
The Tesla UMC checks the ground wiring which the Anker battery doesn't provide. When you plug the UMC to the Anker, look at the LED pattern in the UMC itself, that'll tell you more about the fault.
Even if it did work, it would have taken an hour or more to bring in 4 miles of range from that thing. I wonder if a mobile super charger truck would work? Just something like a tow truck with several batteries on the back and fast charging ports. Just drive up, plug in the car for 10 mins or so, and then have enough range to get to the charging location.
AAA is beta testing this in California already.
John Gray Someone also mentioned a similar thing in Europe. Read it in the comments after writing this.
Anthony Pelchat nice idea honestly
I'd just put the tesla on a tow truck and take it to the charging station. Can't afford to pay a driver to sit waiting for it to charge.
You inspired my parents to get a Tesla! Model 3 awd next Sunday!
Stop them! Get a Volkswagen sharan!! Unbeatable practicality!
Wow
Nice...congrats. Great car
@@GangsterDolphins German Engineering, designed for buy expensive part
Try the inergy kodiak. The anker battery definitely had the "charge" for it, but the inverter was not up to the task. The inergy battery does 30 amps with the 30 amp style outlet.
i question why they never have done a solar roof type of deal?
sono motors has, they claim max 36km / day of just sitting out there in their latest revision of the sion. heard of other cars that trickle charge the 12v battery with a small, built in panel. never seen one.
That is so smart or even panels on the mirror....something right?
@@kingofdragons5932 it would take weeks to charge the car because it would not be big enough even if the entire roof of the car was panel’s
Some trucks (maybe Jerry's) have plugs installed in them in the bed. Maybe you could charge the Tesla from the gas engine of a truck.
You mean like wall socket in gas cars ? Stock ones have like 200W output. So not enough. Maybe aftermarket invertor or gas powered generator.
Won't work, just buy a generator.
Kyle Veatch na get your rc car away from my gas guzzler pollution machine
hahahaha, possibly, if your battery and alternator can handle 10 amps of 240v... not likely.
You didn't try the best portable charger, Omni charge. Expensive, but mine powered my HD TV. Programmable Volt settings, DC and AC, outlet, USB and USB C, and wireless rechargeable. The new one about to be released is even crazier with solar recharging and swappable batteries.
Don't give up until you try the best. Mine has amazed others.
The Omni charge only delivers 100W. How is that going to help? I think the one he had delivers more power.
Sion and Lightyear are putting solar panels on their cars which seems like a good idea for people without garages or to stop a slow drain to zero if the cars sits a while. Also would be useful for this type of situation.
Thank you for debunking the notion that you always have to be successful in order to learn. Great job between you and Ben.
i think the anker powerhouse cannot provide enough current to the car that it could meet minimum threshold current value to start charging ......the another reason could be the square wave coming out of anker powerhouse rather than a sin wave!
Most likely the current. It only delivers a little over 1 amp of current. That's very little amps. Some gaming laptops need more power than that. Hardly enough for an EV.
Just put a small Honda Generator/Inverter in the truck with a can of premixed gas. 😉
Yeah, install a range extender :-)
I was thinking same thing. This little Honda is quiet, light, and puts out 15A @ 120V. powerequipment.honda.com/generators/models/eu2200i-companion
Future Hindsight Awesome testimonial! I've since found a guy who was able to use it to charge a Model S and I think the Model 3 should be even quicker. The best part is it appears it will fit within the Model 3 underneath trunk! The dimensions seems perfect so this means you'll never see the thing until you need it. Kind of like a spare tire :)
Future Hindsight, 500W for 15 hours is 7.5kWh which in a Tesla Model 3 = 28.8 miles.
So, if you buy a 20 year old EU-2000 and install it in your Tesla as a range extender you'll get around 29 mpg. Will it fit in your frunk? Can you charge while driving, or do you have to sit and wait?
The Honda gen will not operate the UMC. There is no resistor between the neutral and ground. A Generac gen will work because it has that resistor. See this vid for details...
ruclips.net/video/Nf6WgQfL7DY/видео.html
It doesn't work because the charger is not grounded. That's the error message
I am so grateful that I am sticking with my 98 Ford F-250 Diesel pick up and is still running awesome, plus a little minor upgrades and replace OEM parts. I am so glad that I did not waste money on the electric car. Plus I always carried a spare Diesel tank back in my tool box that on my bed of my pick up. 😎🇺🇸
Maybe i am a little late. But you can have a genarator (with gas) in the back seat. Then you can charge your car on the side of the road
Pretty sure that it is because there is no ground. therefore the Tesla will not accept a charge. Kmanauto also did something similar with gas generators but got it to work
yes the charger needs to see earth ground . run a jumper wire from neutral to ground and it well work
i tried it with a small gasoline honda generator ... all red. I DID manage to find a gas generator that DID work but it was pretty big.
the charger needs to see earth ground . run a jumper wire from neutral to ground and it well work
Yep, I used a no-name Home Depot 2000W generator and used a grounding rod -- no issues at all.
@whatsinside - lesiure battery with a 2000w inverter, plug into that. Should build the dc into ac up to 2000w which will work. Guaranteed
If you look at the Package (also shown in this video) you can see that it can deliver up to 1.09 Amps at 110V AC
So if the tesla pulls 10 Amps at 110V AC the batterypack just shuts off.
Aditionally when such a batterypack is loaded with it's maximum load, half of the power gets lost through the internel resistance of the battery. So if you somehow manage to charge the Tesla at just 1 Amp you could aditionally cut the batteries capacity in half to figure out, how much the tesla will get.
If you really want a solution I would recomment a traditional petrol powered generator.
This thing can deliver enough energy and you would also solve the problem of always needing to make sure that the battery is fully charged in case of an emergancy. You just need to get gas at the nearest gas station.
The Tesla UMC requires a ground connection. The Anker PowerHouse doesn't have a ground pin at all. It's just a plastic hole. That causes the charging error.
Also, try using a gas powered portable generator. Those don't have a connection to ground, but because they have a proper ground pin, you can use a generator with a neutral bridged to ground, or use an adapter for charging Teslas with generators.
Dan: there is no solution for electric cars
Solar energy: am I a joke to you
Ultra capacitors once their good enough for electric cars?
Yeah because a woman tried to *gas* a Tesla
error idk u saw that video too?
That was great, honestly
I saw that too 😂
Came from that video 😂😂
oh ive seen that vid LOL
It’s the only thing putting me off from buying a Tesla.
I take long road trips up the east coast to rural areas. There isn’t a charger anywhere near there. It also gets into the negatives so the loss to the cold may be significant.
I have a idea for Tesla but I doubt they will take it what if they made a giant battery kinda like a portable charger and then at your home you can charge it and leave it in your trunk and it gives maybe 50 miles. You can also plug it in your Tesla while the Tesla is charging at a station when the battery is dead aswell.
If you stack on free way just ask tow from some big track and charge regeneratively. It's very effective.
Also Tesla battery have some reserve, that is hide from you. Remember recently they temporary unblock it during the hurricane?
This is interested, where did you get the information? ( sorry I havent heard recent news )
Experiment with charging made our russian tesla owners.

Guys what about a battery jump starter? Could it work? You got me very interested in this, you guys definitely got a point there about gas can/power supply battery
Good job. But if you use the nav system, you are given ample warning of how far you can go. I've driven up to 480 miles (each way) in one trip and following the on-screen prompts from the nav system got routed to superchargers with no danger of running out of power.
Dan, it is not good to run down the battery on your car so much. But hey, anything for science.
Exactly what I was thinking. He said in a previous video that you want to arrive at a supercharger with very low battery. Personally I set mine up to not go below 15% just in case there is a detour. And I Never get close to running out
I am pretty sure the GOAL ZERO YETI 3000 will solve your problem... only its $3000
this looks strong enough to move the car
this is exactly what im saying. he'd be set for sure
Or Goal Zero Yeti 1400.
Just make a cas can shaped portable charger
Like a diesel generator that runs on cooking oil.
How about just a peer to peer emergency charger. Notification to Tesla and option for passerby to accept emergency charge (car to car)
I’ve seen some people have the same issue with some generators. The issue in that case was the generators weren’t properly grounded. Some generators can trick the tesla, some can’t. I’d try a few different battery packs.
Or you could use a portable solar panel.
Even a 350watt solar panel would take days to charge the car!
MegaTechGuy not if you only want a mile or so.
Sasha Sharman it would still take a LONG time
Spencer Dunshee agreed, but it's a clean green solution to get you out of a sticky situation.
Sasha Sharman ya, but it would be faster to use a battery with an inverter strong enough
How about buying a 2000W inverter, and keeping that in the car. In the event you need just one mile or so, you can hook the inverter to the 12V lead-acid battery, and charge the big lithium battery at 12A and 120V for about 10 minutes. That will give you about one mile of range.
Incidentally, that 5 gallon gas can will give my car 280 miles of range.
ljfinger good idea
what car do you have that gets about 56 miles to a gallon?
Prius Prime. Best of all worlds - 99% EV when in-town and 56mpg, over 600 miles of range, and the ability to refuel anywhere in 3 minutes when going out of town, especially when going off the beaten path (which I'm known to do).
you don't need a $500 anker powerhouse when you could get a $100 lead acid with the same capacity
There is also the option for 240v inverter , then dream big on wattage, say 10k, then you have your self a mini super charger,
I like Lincoln’s glasses
There is MDI that has a compressed air generator, not sure how portable it is but it does work with solar to recharge it.
It would be cool to see the new Tesla semi equipped with a few battery packs that would allow you to charge on the side of the road as it’s own roadside assistance. especially in areas that would go from LA to Las Vegas or Los Angeles to Fresno to the Bay Area. Just a thought
The software just needs to force the car to shut down, so you have to pull over...And after 60 seconds of being parked and thinking about how screwed you might be...BLING..."You have 5 miles remaining."
Interesting. And what if people will rely on that and the station is 6 miles away?! 😂😂
@@IonutVEpure you could drive for 5 miles and then push it for 1 miles
@@tonk9246 it would be basically impossible to push against the force of the electric motors (it takes alot of force to turn a electric motor when there is no electricity)
@@Johnny-tq9no Put in neutral or tow mode
Good thought adding a stopping mechanism to tell the drivers to find a place to charge
Maybe you could use a gasoline generator?
what about a generator
secret model 3 thing, you can have 2 chargers at the same time, where you usually charge the model 3 you can get to the other side and you’ll have a dual charge with a quicker charge, if your at a supercharger for 45mins and you don’t want to be there for 45mins, the dual charger will go down 6mins making it to 39min charge.
It’s very interesting and this is in every Tesla!
I’m a big fan to both of your channel. Thank you guys!
Very cool what's inside
WAT
Must not be real musk cuz elon should be Elon with capital
What if u use a mini generator, output is 110v/10a?
This could work at 10 amps.... The thing they were using here could barely do 1. I have a similar device and they don't do much. But a generator- like the silent compact ones by Honda- could be bare minimum solution.. Essentially you're charging a battery with a battery. What if Teslas could charge other Teslas to get them by? hm
I’m the 64th comment probably no one would read this so I’ll like it
Hey I just had a great idea. What if there was a trolley you could use to roll your batteries from the car with you? Like bringing your empty gas tank with you? Would that work?...
Of course there would need to be good security. We wouldn’t want everyone just stealing the batteries from the car. But does the basic premise work? You’d eject a portion of the batteries, roll them with you, suitcase sized or so, maybe connect them to a portable charger, and take a taxi over to somewhere with some electricity to go charge them and bring them back?
I feel with your far you get, you can easily not run into this issue if you just plan a bit, which you should be doing anyway for a roadtrip
That’s why you get a hybrid.
Or E-rev
Or just don't let it run out?... Irresponsible
Hybrids use electric when stopped you dont use it roads in hybrids thats only with full electric cars
nexus prime my dad just bought a hybrid like 1-3 months ago and it is so cool it also still has the new-car smell or whatever still that I love
The extra cost of hybrids won’t be fulfilled unless you keep the car for more than 15 years
THATS CUZ ITS JUST 2.4 AMPS
thankyou if he turned down the cgarge currant to that itr wud hav worked a lil bit
We need solar panel system on new Teslas
This is perhaps what you would need to ensure a transfer of energy.... "AIMS Power 5000 Watt DC To AC Power Inverter, 5000W Max Continuous Power, 10000W Surge Peak Power". This in concert with any large capacity deep cycle battery or even a modest custom 18650 cell battery pack that could be custom made would provide the ample transient current necessary to make the Tesla Happy. The millisecond push of current must be adequate . I hope this is helpful. The Model X has ample storage area for such a "emergency range extender."
AAA has a service in a few areas with both CHAdeMO and Level 2

The solution is called "trip planning" look it up.
In theory this could totally work but you will need a bigger inverter. The Anker unit you have is on rated to 120 watts on the inverter.
You could get a 1000-2000 watt inverter with a 12v batter and you will be set!
Would love to see that test!
@WHAT'S INSIDE? FAMILY
Both cars are not charging more than likely because the battery pack you are connecting to, is not grounded. Therefore you are getting a red ring.
Hmmmmm you may have a point. But I think those inverters hook up the ground to neutral
A small gas generator will work
Tesla could produce a portable emergency battery of its own, made to work with their own cars, good for 10+- miles.
Calculate your miles before leaving home. Problem solved.
Detours, Wind, Temperature, Hills, Driving Habbits....etc can make the range vary by as much as 25-50%
you need to ground the power source, the mechanical ground ( 2 ground wire)
It needs a trick to overcome the ground security check on the charging port. As it checks if it is pluged in to the grid or not! But you could maybe check that with some tesla service car to see what the trick actually is to make it work.
Just use hydrogen instead of lithium ion batteries 🤷♂️
Maybe an generator that you can put in you car is an solution
Your Tesla still runs on fossil fuels.
Most power plants burn coal.
Yup all the self righteous ZEV's are actually coal burners.
Now you know why Trump wanted to get the coal mines back online and the miners back to work.
Correct except in the cases of people who also have solar powered homes which Tesla also provides. However even though the fast majority of these cars somewhere along the chain are coal powered, they are far far more efficient than any ice motor or hybrid and can be run coal free via solar unlike an ice motor.
You should brush up on your thermodynamics. Your statements regarding efficiency are less than accurate.
@@almosthuman4457 then correct me
However they can put larger restrictions on power plants than people driving
love your show & spacex. We traveled to Boca Chica to the the starshing get built. & we got the S dual motor fsd last Christmas 🎄 😎 still have the cybertruck tri motor or 4 motor fsd on order, i got lots of solar & backup battery system to charge them both. love tsla stock
The posts stating you have a ground fault because there is no connection between the earth ground and the neutral line may be correct. But, the main problem is the AC Output rating of the Anker Power House. You showed us the back of the box and the device is only rated for 110 VAC at 1.09 Amps. You need a power inverter with at least a 12 Amp output over a 1 hour period to get 3 or 4 miles of range for the car. I don't know what amperage will be drawn from a 12 VDC power source for that size of inverter.
I thought this guy is going to put gas in his Tesla ha
You guys are aaaaaaaaaaaaaaaaaaaaaaaaaaaaawsooooooooooooooooooooooome
I just can’t justify buying a Tesla they are just all around disappointing cars
I think I read somewhere that a company or an individual goes around charging cars. When you're in trouble you give him a call and he comes out and charges the car some. Probably less expensive by far than a tow truck and creates a new job.
You may have the same problem as a lot of gas generators. You need to bond the ground and the neutral. I got that same charge cable fault with my genereator until I made an adapter that jumped ground to neutral now it works. The charge cab;les refuse to operate unless they pass the ground connection test
First world problems.
Tesla needs to put a solar panel on the top of their cars
Insufficient amps or not sensing the secondary ground that is in a typical home outlets. My surge protector will warn if there is a missing ground or the socket is wired backwards. My guess
I think that tesla could put a large battery pack that you could access from the trunk or something that will normally just be part of the battery, but if you need to you can take it out and charge it at a supercharger or maybe even just a normal outlet. Then you could put it back in and have 5 or 10 miles to get to a supercharger
I’m betting the battery pack puts out a pulse width modulated AC output. If you get a more expensive UPS with true sine wave output, that might do the trick.
My car won't charge if outlet isn't grounded. I'm guessing that's part of the reason this won't work. A battery of that size could certainly be capable of the amps required - ebikes do it all the time!
That's the problem though. You could easily fool the charger by connecting the ground pin the neutral terminal. The reason it didn't work is because it can only deliver around 100W of power. The charger needs at least 1500W. A portable gas generator would have worked.
Try the smallest generator out there that can deliver the minimum Ampere you need. How big and heavy is it to have on board all the time?
I Deep Cycle Battery may be more than enough to provide the current needed. Also, as an idea, there are Lithium car starters that have the ability to dump a lot of current. My guess is that the Tesla car is looking for a spike of energy that is broad and has an instantaneous current in excess of 30-40 amps
Sine wave is the issue probably the software is designed to detect the sine wave to the connection to protect the electronic components so it won't give you the option to charge a single watt.
