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.

  1. Products tested, in no particular order (affiliate links):

    I forgot to mention this in the video, but even the โ€˜winnerโ€™ gets the most lukewarm recommendation possible from me. Itโ€™s 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.

  2. 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

  3. 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.

  4. 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

  5. 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
