I tested how much solar energy all these solar power banks collected after being left outside for 2 days. Then I charged them up and tested how much battery capacity they *actually* have and compared it to their listed capacity. I also talk about a flaw present in the current crop of solar power banks.
Note: Listed capacities came from the solar power banks themselves. In the case that the power banks only reported their capacity in milliamp hours (mAh), I calculated their watt hours by multiplying their milliamps hours by a voltage of 3.7V (the nominal voltage for the Li-ion batteries used in most power banks) and then dividing by 1,000.

I forgot to mention this in the video, but even the โwinnerโ gets the most lukewarm recommendation possible from me. Itโs just hard to trust the long-term quality of cheap power bank brands โ let alone one whose actual capacity is so far off from its listed capacity. So buyer beware.
A better alternative is probably just buying a dedicated solar charger and using that to charge a regular power bank. That way you can keep the battery out of direct sunlight. Not to mention, solar chargers tend to have bigger solar panels and thus output more power.
Wait, Can you still the ones with 4 panels with only three extension ones, if yes that would mean we can technically prevent the lithium battery from heating up
My thing is $80 for one, or $10 for 2 of the cheaper ones.
Don't like getting hot & don't like being cold
Thanks for the fair warning!
Isn't it illegal that they lie about their capacity?
Unfortunately solar and battery prices came down so low that these junk products now appear on the market. They are truly useless.
Focus on buying high quality, high capacity power banks and charge them from mains power, which is far less polluting than all the energy and petrochemicals that are used to make these products.
Thanks for the test.
Thanks for being straight with us!
If you wrap the inside battery with ceramic fiber or ceramic wool… That will stop it from catching any heat while left outside in the hot sun
another great idea…. on paper… good info.
Wow, thank you for the eye opener
well done.
I have one and the instructions literally said that it might take 6 days to change just using sunlight ๐ญ

How much
So what size of solar panel would be needed to fully charge a phone in, say, 3 hours?
Thanks a lot. The single solar powerbanks are mostly used with an extra solar panel.
How can I ordered that
I wished I watched this video before buying my solar USB battery.
crazy question and not like I know one way or the other but do you need to fully discharge before charging to get the most accurate battery capacity ? I thought I heard that some where maybe for quadcopter lipos or something
These things are sooooo disappointing.
Very informative, thank you
Finally a real honest product review , I own almost all of those and agree with everything u said thanks for sharing
I'm sure they could make them better, but the last thing they want is people getting free energy.
Holy cow Iโve never seen a YouTuber go straight to the point like this, others should learn from this lad.
Can I charge these with outlets
Sounds about right with all the "sustanability" trend. You buy it with good intentions, and then use it as a regular powerbank plugging it to the wall.

Anker Solar is nologer listed on official site. Nor there are any mobile solar power banks on anker site.
This video needs more likes. Short to the point and fair comparison
Thanks. this was actually a very good and useful review. Saved me some money as well.
Thank you, can you tell me what tool are you using to test for Wh
Avoid Chinese knockoffs
Why the annoying music? Could not finish
Good video, was looking at the specs of these power banks, and my scepticism had proved correct..
Wireless charging on a power bank is the goofiest thing I've ever heard, especially on one that is outdoor focused. They're probably consuming as much power as they're producing just checking for a phone to charge
Phone never test to charge but mi pad 5 charge slow use less old solar power pank one light two charge port need rail.y charge your phone and mi
Pad 5
Thanks for your research results. I've bought too many of these disappointing devices and get shot down on their abilities. Maybe I'll check the development process in a few years.
