The 5,000 mAh rating is at the internal battery voltage of 3.7 volts. You're drawing power out at 5V and then the phone is wasting some power in the charging process. So you cannot accurately say none of the products delivered the promised amount. I've reviewed a lot of powerbanks and I suggest you use a proper USB watt meter that can measure the total power drawn out and then a dedicated constant current dummy load instead of iPhones.
I strongly recommend taking special care to avoid cheap solar chargers. With a very small panel some devices literally could take weeks of sunlight to charge.
+Alex Rafe thats true story man, last year I bought a cheap chinese UPS with nothing inside other than a full concrete and a straight up cable to the plug.
This may be irrelevant but I've seen a supposively 1 terabyte USB opened with the encasing having the USB port which had wires soldered (hot glued too) to a microSD card adapter board with a 1gigabyte microSD card in the adapter. So it looked like a normal USB flash drive from the outside.
+LinusMLGTips The entire ugly skins thing was planned. Dbrand sent out twitter message asking people for the ugliest iPhone SE skin combinations they could come up with, and send Linus their favorites.
Why didnt you use one of those voltage/current measuring USB power meter that can also measure mAh? I have one. You charge your battery bank to full, connect a device to the bank via the USB power meter and watch the mAh count rise. When the bank has fully drained, I get the exact mAh of the battery.
Here's the one I have. It's pretty handy. www.amazon.com/PowerJive-Voltage-Multimeter-chargers-capacity/dp/B013FANC9W/ref=sr_1_2?ie=UTF8&qid=1457662332&sr=8-2&keywords=usb+current
+Nissan Karki Well, yes. The thing is that those power banks can act completely differently when they are discharged to when you actually use them to charge something. Chances are that cheapo ELEGIANT would have gotten similar numbers to others if you just discharged it only to find out it can't charge a phone battery at all because of for example the voltage dropping too low, which is something you wouldn't see in synthetic charge & discharge test.
+Deses So you prefer a capacity measurement over real life comparing? I don't know what you do with your battery bank, but I personally charge my phone with it, so I prefer seeing how it does at charging, instead of some measured data.
Yes, measured data is f-ing great, I know. I'm an engineer, I know how great measuring stuff is. But seeing those capacity ratings on the banks are so far off sometimes, why do you trust numbers so much? The way this experiment was held was perfectly legitimate. It might not be perfect, but it gives results that are clear enough so you can base a conclusion on it. You go right ahead if you have plenty of money, and go and measure the real capacity of those banks. This'll work just fine for me, and it should work fine for anyone.
Linus, usually the MAH capacity is of the 1 cell lithium ion battery on the inside which it 4.2v at a full charge and ~3.3v at empty. but phones require 5v to charge so there is a built in circuit that boost the voltage to 5v but draws more power. so a 10,000mah 1 cell li-ion will only do ~6,000-7,000mah at 5v. LOVE THE SHOW!!!
+Anas Malas "Tech tips", this is not an electronics channel, but what you are looking for is actually important.. especially if you consider banks with AC, and other outputs. What I'd like to hear in a tech tips videos is was the advertised output as advertised. it's one thing to have a 5000mAh bank, it's another thing if it can only deliver 0.2A.
As a amazon reviewer who cuts their teeth reviewing battery banks this review could have been better. Testing capacity should be done with a USB power meter and a USB load tester. That will give you the exact mah output. If the advertised mah is correct the output mah should be around 60% of the advertised mah. This is due to the voltage up step from the lithium cells 3.7 volts to the output volts of 5. There is also a roughly 10% loss due to inefficiencies in the battery management circuits. And also another 10% loss to heat and resistance in cables/connections.
Agreed it wasn't as accurate as possible but let's face it, not a lot on this channel is done 100% right. They have to cater for everyone which is easy to say not to do.
i Think is test is not that bad really in more the field test style video and the question is, would a more scientific test come to a different Result?
Xiaomi's battery banks are the best IMO. my anker died after a couple of months but all 6 Xiaomi power banks i have at home have been working great for the past 2 years and still going strong.
Good video, but a question I have for a long time was not discussed. The batteries in those banks are LiPos, they have a voltage of 3.7v and use a dc converter to deliver 5v. Now, is the capacity advertised equivaltent to the output voltage of 5v or to the cell voltage of 3.7v?
+Brendan Pert that's the perverse thing, I'm sure a fat iphone would sell like hotcakes.... "thin" just doesn't cut it once you experience the reality of short battery life.
the average joe buys into the 'maximum thin' silliness. however to be fair, IMO sufficient battery life is >24 hours of general usage time (using a variety of apps, doing some calls, some texting, a bit of internet browsing, app/OS updates, Et Cetera).... and to do that, phones would be literally the size of a brick. and weigh about as much as one.
+SunyaMacs Not really. Yes, there are many fake ones, especially on sites like ebay! I have got mine from gearbest.com which has oficial Xiaomi products directly from China. There are many more sites like Banggood,etc that have those.But on gearbest you can the 10.000 cheap.Here:www.gearbest.com/mobile-power-bank/pp_187685.html for 15-16$ or you can do a "trick" but getting a case for the powerbank here:www.gearbest.com/iphone-power-bank/pp_232156.html and below on "buy together and save" you can choose the powerbank for a total of 14.30$ together with the case. (so you get the powerbank+the case for less that the powerbank alone....makes sense xD)
Couple things I have an issue with here, 1. LiPo batteries need to be conditioned to work at expected values. 2. The phones could still be using different amounts of power without your knowledge (updates or other automatic nonsense). 3. Wouldn't it have been cheaper and more reliable to get several multi-meters and some resistors to create a constant 1 or 2% current drain of the batteries 'capacity' (52 or 104 milliamps for 5200mAh battery) and see how many hours it would take to drain? 4. Why did you not at least hookup adafruit usb current meters to each phone?
Tell me how it's not, you still have the charge up both batterys, you get a instant 100%, but you have to turn off your phone. You still have power stored, except it's only for one specific device.
***** that's true that you have to charge both battery, but when your main battery dead, you just swap it, and dont have to charge it again with your battery bank
Speaking of power banks and Cheero, if you can find them at Computex, could you please ask them to make an updated version of the Handy with USB-C cable and input to replace the micro-B ones(and maybe QuickCharge 3.0)? They are impossible to contact, like most Japanese companies. Thank you in advance.
Richard Dicks I have the Anker PowerCore 20100. I like that it's matte black and has a nice, huge capacity. It's pretty compact for how much energy it packs.
+HyperStryker I've had the 10000mAh PowerCore+ for about 7 months, and I love it too. This one even supports Quick Charge, and it works brilliantly even after a full charge cycle a few times a week!
Cool test (I've had an Anker v1 for several years), but you only looked at dollar-to-energy-recharge ratio? What about weight-to-energy-recharge-ratio?
For all the people bitching about dbrand: It might be sponsored content, but it's not sponsored content where the sponsor controls editorial positions, and is still informative content. And it's obvious that it is sponsored content rather than undisclosed. I feel like Linus and Nick Light deserve credit for arranging such a situation.
RavPower is the best, I'm not sure why it wasn't included in the list. I got their 26,500 mah pack for less than 30 bucks. Quality internals, fits in my pocket, and can charge my phone a dozen times per charge.
this is terribly un scientific, you can't convert mah battery to battery and using iPhones as a load is pretty bad too but it was a good idea and was done nicely
I have two of those lipstick style banks and they may be good enough for a cell phone top up but even my tablet it just barely charges up (7" Asus Memopad)
Few issues with this experiment but otherwise cool. Charges don't have 100% efficiency rates. IE A 5200 mAh charger may not charge a device to that amount. 80-90% efficiency rate should be considered. Also you could have turned the Iphone off while it was charging to reduce the power usage of the phone.
+goodman854 Its a given because of the energy and voltage conversions. ebay has cheap usb testers, displays mAh, also buy a usb resister/drain device and you can get the real usable capacity of your battery banks. You don't have to use a phone or whatever at all, its faster and simpler to just use a resister.
+goodman854 What would of made it better is to have a 1A load on the usb. This will remove the phone from the equation. Also opening up the unit will show (to look inside) will show how many cells are inside giving a good estimate of it size.
I love this video. great start to more detailed research you can do and dig deeper. I'd like to see more about these such as, longevity of the battery bank, charge on the phone does it change with different battery banks.
+Dhrumil Shah (Personal) more like R8 vs chinese kit car R8... looks similar, but performs very different so thats why he threw that 1 no name brand in against the FIVE named brands we'd probably all choose to buy
+LamboPlays certainly. but the one in question in this video is a random nobody brand who the hell is that do you even know what you're doing product - and THOSE - are terrible.
Looking to buy a new backpack and I was wondering if the usb plug from inside to out work with fast charging or does it lower the speed from the portablele charger?
+washthethrone But what they have not accounted for is longevity, differences between models within same family (one was a lot more expensive luxury version, so why not go for more apples to apples comparison?), and last one was rock bottom. Why not picked 4-5 cheapest generic? Results would have so much different. Some how i keep expecting more from LTT, but i think goodwill is finally running out for me...
+Vaidas Šukauskas First, why all the hate? Second, the test was meant to compare garbage cheap between more expensive, not between multiple lower quality or higher quality battery banks. The video was more about the money involved to charge a phone. Third, longevity? The capacity of a battery bank determines how long the bank will last in this case.
hey linus, not sure if you made a video about this, but can you make a vid about weather or not non-native resolutions for things like gaming for other applictions are practical?
I don't understand the Actual vs Advertised Capacity Compared to Anker chart. Is Anker's red line it's actual capacity and that's the base line for the other's advertised capacity? Is the red line for Anker the actual capacity as if it was the advertised capacity and the others are how they did in comparison to their actual and advertised capacity? I ask because when you make a chart that says blank vs blank I'm expecting 2 sets of line graphs. One set is the actual and the other set is the advertised. Then Anker can still be the base line in comparison to the others for their respective graphs. I don't understand what the graph itself alone is supposed to communicate.
Linus I would like to know if you depleted and recharge the battery Banks more than once because with lithium batteries the more times you deplete them and charge them to a certain extent the milliamp should increase past a certain point. the first 2 or 3 times you charge them is not a good representation of the actual batteries capacity
Are there any energy star rated powerbanks on the market? I'd like to get a large capacity bank ideally suited for trickle charging with a solar panel, mine being an Anker PowerPort Solar 21w portable panel.
Another thing to consider is current: Different batteries output at different currents (500mA, 1A, 2A, 2.4A, etc.) which could alter the results of the test and value of the batteries.
I was actually wondering, if some of the banks charged faster than the others since Anker for example is marketing their IQ power thingy which is supposed to adjust to the device being charged.
Knowing which cells each brand use would be interesting to know, a lot like to push that detail as a selling point (Panasonic, LG and Samsung are often mentioned) Glad we got some really useful graphs in this to make sense in real world purchasing decisions.
@Linus , i recently got interested to know whats inside of the powerbanks i own. after some thinkering i might have gathered a part of the answer as to why some battery bank perform better than others. most powerbanks use 18650 lithium cells . which are typically rated between 2,100mAh to 3,100mAh. however a single cell has a typical voltage of 3.7Volts . knowing that the usb voltage standard is at 5Vdc it means that the circuitry of the powerbank convert the 3.7(typical voltage) to 5Vdc. you have to consider that these circuits (named step-up converter) aren't 100% efficient. Furthermore, the '''step-up'' conversion of 3.7Vdc to 5Vdc reduces the effective capacity of the unit. just as an example, the cell could have a real capacity of 2,500mAh @ 3.7Vdc but after conversion might only develop 1,800mAh capacity. So it would explain why some offbrand units do not perform to their advertised capacity while still being accurate about their battery capacity. I haven't opened more expensive units yet but i can assume these higher quality/priced items be rated at their effective output capacity rather than the battery capacity.
you guys should really get something like a cafe battery analyzer for things like this. using a bunch of iPhones just has way too many variables to be accurate
also not mentioned is that part if the power us going to power tge battery bank. Not to mention that the charging cables used can make a world of difference too.
Hey LTT Guys. Really nice that you did this. Not many reviews online take this amount of care to test quantify battery bank performance. However. I can't help but wonder why you did the tests the way you did. Did you use phone charge cycles as a measurement to make the data more relatable? It seems simple to me to get really good data buy just placing a constant current or voltage load on the banks and a datalogger. I'm an EE / Software Engineer so maybe it's just me, but I think a big part of your audience is tech savvy enough to both now wat was going on, and appreciate the scientific approach. :) Canada is a long way from Denmark, but I would have loved to help out / consult and I suspect someone in your area with the right gear might want to for free as well :) Anyway. Dont now if you get this, but love your videos!
Did anyone ask for this? How has it been since a quality motherboard review and what happened to the awesome build guides with the chapter selections and dope intros?
finally a channel that actually ask for my opinion of the video if i like it or not, rather than all dem videos "saying remeburr tu haiet dhat laikke" #imasaltyboi
An improved testing methodology would have been better, like having a constant resistive load and measuring the actual capacity of each battery bank as well
I've had the Anker Astro 2nd Gen 6400mah for years and I've loved it. Glad to see it performing well. I'm about to buy an Anker Powercore+ 10050mah one.
I got my Aukey 20,0000 battery bank, I've used it on and off for a whole week without charging it once, and it's still above 70% charge. A lot of people apparently are getting shammed with it, but mine are keeping up a lot. And I've had it for a little over two months and it's still working as if I bought it today.
For me, the time to charge my phone is more important than how many charges. It doesn't matter if I can get 2 or 3 full charges in (even though my s6 would only get like one and a half) because the time to get that full charge would basically he the same amount of time for me to make it through the day on a quick charge

Ivan Stroganov Yeah i also thought 15 dollars was too good to be true, I already have a 16000mAh from banggood which is genuine.
Did you cycle the batteries a few times before running the test? That tends to be necessary to get the full capacity out of them.
There's something about Linus's voice that makes it pleasant to hear.
2:40 "complete with their high quality vinyl skins, of course"
am I the only one that thought this line was hilarious?
No battery bank needed when you've got an extra battery for your phone...
You're basically just doing the same thing except you have to turn off the phone to change the battery.
+PianoVideosJustForU (PVJFU) no it's not
Tell me how it's not, you still have the charge up both batterys, you get a instant 100%, but you have to turn off your phone. You still have power stored, except it's only for one specific device.
***** that's true that you have to charge both battery, but when your main battery dead, you just swap it, and dont have to charge it again with your battery bank
Yes, you still have powered stored, just like you do with a battery pack.
I thought you were going to disassemble the battery banks to inspect the cell arrangement to is whether they get close to the capacity stat.
I want to see laptop power banks showdown!
+Martin Smolko yeah that would be cool
Speaking of power banks and Cheero, if you can find them at Computex, could you please ask them to make an updated version of the Handy with USB-C cable and input to replace the micro-B ones(and maybe QuickCharge 3.0)? They are impossible to contact, like most Japanese companies. Thank you in advance.
OH NO HES TURNING INTO TECHSOURCE
NOOOOOOOOO
DBRAND WHY
WHY
That was actually a cool and useful test. The takeaway for me is that the Anker is probably the winner in terms of performance and price.
I personally prefer the Anker brand with their nice warranty and quality products for a reasonable price.
I love my anker 10k mah
Thing that sucks about it is it's glossy tho
I'm tempted to get Ankers USB C power bank. Mostly for the novelty and changing USB C laptops
+Alex Rafe I love anker products but would suggest looking at Ravpower for type C as well as it has more versatile ports
Richard Dicks I have the Anker PowerCore 20100. I like that it's matte black and has a nice, huge capacity. It's pretty compact for how much energy it packs.
+HyperStryker I've had the 10000mAh PowerCore+ for about 7 months, and I love it too. This one even supports Quick Charge, and it works brilliantly even after a full charge cycle a few times a week!
no surprise here anker makes the best everything.
Why were the mAh ratings not on the graphs, as well as the prices? Would have been nice i think.
Just use a resistor and monitor the batteries voltage over time lol...
Cool test (I've had an Anker v1 for several years), but you only looked at dollar-to-energy-recharge ratio? What about weight-to-energy-recharge-ratio?
Nobody likes my idea?
I think ELEGIANT stands for "ELEctric GIANT" or something like that :)
great video linus, was just looking for a battery and this really helped! :)
I'm taking a dump right now, great entertainment for my current activity :)
For all the people bitching about dbrand: It might be sponsored content, but it's not sponsored content where the sponsor controls editorial positions, and is still informative content. And it's obvious that it is sponsored content rather than undisclosed. I feel like Linus and Nick Light deserve credit for arranging such a situation.
ELEGIANT = Electric Giant. Get in the game linus
i live in florida where power during hurican season can go out for 5+ days how long does the charge one one of the battery banks last?
I don't have a battery bank :( 0:16
RavPower is the best, I'm not sure why it wasn't included in the list.
I got their 26,500 mah pack for less than 30 bucks. Quality internals, fits in my pocket, and can charge my phone a dozen times per charge.
Who doesn't hAve one?
Me...
We want some segments like these! Bring more!
this is terribly un scientific, you can't convert mah battery to battery
and using iPhones as a load is pretty bad too
but it was a good idea and was done nicely
I have two of those lipstick style banks and they may be good enough for a cell phone top up but even my tablet it just barely charges up (7" Asus Memopad)
Few issues with this experiment but otherwise cool. Charges don't have 100% efficiency rates. IE A 5200 mAh charger may not charge a device to that amount. 80-90% efficiency rate should be considered. Also you could have turned the Iphone off while it was charging to reduce the power usage of the phone.
+goodman854 lel
+goodman854 Its a given because of the energy and voltage conversions. ebay has cheap usb testers, displays mAh, also buy a usb resister/drain device and you can get the real usable capacity of your battery banks. You don't have to use a phone or whatever at all, its faster and simpler to just use a resister.
It can't charge while it's off because it will just turn itself back off
+goodman854 He specifically addressed that point towards the end of the video before the sponsor spot.
+goodman854 What would of made it better is to have a 1A load on the usb. This will remove the phone from the equation. Also opening up the unit will show (to look inside) will show how many cells are inside giving a good estimate of it size.
I love this video. great start to more detailed research you can do and dig deeper. I'd like to see more about these such as, longevity of the battery bank, charge on the phone does it change with different battery banks.
Wtf you did name brands vs the worst Chinese on you could find... It's like comparing a R8 vs a Civic.
+Dhrumil Shah (Personal) more like R8 vs chinese kit car R8... looks similar, but performs very different so thats why he threw that 1 no name brand in against the FIVE named brands we'd probably all choose to buy
Not all Chinese products are bad.
+LamboPlays like xiaomi
+LamboPlays
certainly.
but the one in question in this video is a random nobody brand who the hell is that do you even know what you're doing product - and THOSE - are terrible.
fuck you, I know some civics with dual turbos and a k20 that would smoke any starter trim r8
keyword, starter trim
Looking to buy a new backpack and I was wondering if the usb plug from inside to out work with fast charging or does it lower the speed from the portablele charger?
totaly wrong considering all of the power banks have diffrent capacities
+ersey hersey They accounted for that.
At 4:09 he says that he knows that they are not all the same, and that they will correct for the different capacities when compiling the results
+washthethrone But what they have not accounted for is longevity, differences between models within same family (one was a lot more expensive luxury version, so why not go for more apples to apples comparison?), and last one was rock bottom. Why not picked 4-5 cheapest generic? Results would have so much different.
Some how i keep expecting more from LTT, but i think goodwill is finally running out for me...
+Vaidas Šukauskas First, why all the hate? Second, the test was meant to compare garbage cheap between more expensive, not between multiple lower quality or higher quality battery banks. The video was more about the money involved to charge a phone. Third, longevity? The capacity of a battery bank determines how long the bank will last in this case.
also in the video they have the best bang for the buck in the chart and also accounted for the capacity in the other graph
hey linus, not sure if you made a video about this, but can you make a vid about weather or not non-native resolutions for things like gaming for other applictions are practical?
Eeewww, did I just see an iPhone?
They're torturing them by making them run out of battery multiple times. My favourite kind of torture.
+Zilla I like how you think..
TheOfficialNar I like how you think
MyFaceHole I like how *you* think
+MyFaceHole I think how you like.
Linius can you show larger power banks i g camping a lot and the smaller ones don't really get the job done.
dbrand skins are getting uglier and uglier smh
I don't understand the Actual vs Advertised Capacity Compared to Anker chart. Is Anker's red line it's actual capacity and that's the base line for the other's advertised capacity?
Is the red line for Anker the actual capacity as if it was the advertised capacity and the others are how they did in comparison to their actual and advertised capacity?
I ask because when you make a chart that says blank vs blank I'm expecting 2 sets of line graphs. One set is the actual and the other set is the advertised. Then Anker can still be the base line in comparison to the others for their respective graphs.
I don't understand what the graph itself alone is supposed to communicate.
I have an Insignia 20,800mah battery pack. It takes a long time to charge, but it lasts a long time and you can charge 3 things off it at once.
Linus I would like to know if you depleted and recharge the battery Banks more than once because with lithium batteries the more times you deplete them and charge them to a certain extent the milliamp should increase past a certain point. the first 2 or 3 times you charge them is not a good representation of the actual batteries capacity
I've stoked someone I trust is finally figuring this out.
Are there any energy star rated powerbanks on the market? I'd like to get a large capacity bank ideally suited for trickle charging with a solar panel, mine being an Anker PowerPort Solar 21w portable panel.
Another thing to consider is current: Different batteries output at different currents (500mA, 1A, 2A, 2.4A, etc.) which could alter the results of the test and value of the batteries.
I was actually wondering, if some of the banks charged faster than the others since Anker for example is marketing their IQ power thingy which is supposed to adjust to the device being charged.
Knowing which cells each brand use would be interesting to know, a lot like to push that detail as a selling point (Panasonic, LG and Samsung are often mentioned)
Glad we got some really useful graphs in this to make sense in real world purchasing decisions.
@Linus , i recently got interested to know whats inside of the powerbanks i own. after some thinkering i might have gathered a part of the answer as to why some battery bank perform better than others.
most powerbanks use 18650 lithium cells . which are typically rated between 2,100mAh to 3,100mAh. however a single cell has a typical voltage of 3.7Volts . knowing that the usb voltage standard is at 5Vdc it means that the circuitry of the powerbank convert the 3.7(typical voltage) to 5Vdc. you have to consider that these circuits (named step-up converter) aren't 100% efficient.
Furthermore, the '''step-up'' conversion of 3.7Vdc to 5Vdc reduces the effective capacity of the unit. just as an example, the cell could have a real capacity of 2,500mAh @ 3.7Vdc but after conversion might only develop 1,800mAh capacity.
So it would explain why some offbrand units do not perform to their advertised capacity while still being accurate about their battery capacity.
I haven't opened more expensive units yet but i can assume these higher quality/priced items be rated at their effective output capacity rather than the battery capacity.
Great video, can you guys keep running those banks to get an update later on to compare how they do degrade?
what dbrand skin was on linus' macbook air in scrapyard wars 3.
you guys are really honest about your reviews :D
Keep up good work :D
you guys should really get something like a cafe battery analyzer for things like this. using a bunch of iPhones just has way too many variables to be accurate
also not mentioned is that part if the power us going to power tge battery bank. Not to mention that the charging cables used can make a world of difference too.
Hey LTT Guys.
Really nice that you did this. Not many reviews online take this amount of care to test quantify battery bank performance.
However.
I can't help but wonder why you did the tests the way you did.
Did you use phone charge cycles as a measurement to make the data more relatable?
It seems simple to me to get really good data buy just placing a constant current or voltage load on the banks and a datalogger.
I'm an EE / Software Engineer so maybe it's just me, but I think a big part of your audience is tech savvy enough to both now wat was going on, and appreciate the scientific approach. :)
Canada is a long way from Denmark, but I would have loved to help out / consult and I suspect someone in your area with the right gear might want to for free as well :)
Anyway. Dont now if you get this, but love your videos!
Did anyone ask for this? How has it been since a quality motherboard review and what happened to the awesome build guides with the chapter selections and dope intros?
Greetings from +Ingress Agents! Great info!
Do a stress test with the iphone and the elegiant battery until it explodes? Or do you have to return the iphones?
finally a channel that actually ask for my opinion of the video if i like it or not, rather than all dem videos "saying remeburr tu haiet dhat laikke"
#imasaltyboi
So what was the difference in actual vs advertised capacity?
An improved testing methodology would have been better, like having a constant resistive load and measuring the actual capacity of each battery bank as well
love your videos dude
please do a video on what types of power banks are best for the dollar etc solar,led display,size
I've had the Anker Astro 2nd Gen 6400mah for years and I've loved it. Glad to see it performing well. I'm about to buy an Anker Powercore+ 10050mah one.
Cant go wrong with Anker.
I got my Aukey 20,0000 battery bank, I've used it on and off for a whole week without charging it once, and it's still above 70% charge. A lot of people apparently are getting shammed with it, but mine are keeping up a lot. And I've had it for a little over two months and it's still working as if I bought it today.
Do an update to this with charge holding capacity over a month or two, my 10,000 mAH end up at v little charge over a month stored no use etc
Congrats for the video, really nice
For me, the time to charge my phone is more important than how many charges. It doesn't matter if I can get 2 or 3 full charges in (even though my s6 would only get like one and a half) because the time to get that full charge would basically he the same amount of time for me to make it through the day on a quick charge
4:30 who's surface pro 3 is that?
So why didnt you take a powerresistor and set a timer?
What were the costs for all of the battery banks?
