    Default Waterproof Solar Power Bank - Any good?

    Thought id try a Tech subject

    Does anyone own one of these?
    Does it perform as promoted?
    The solar recharge side of things i am meaning.... Cheers

    I suspect its just a new way to sell a Power Bank, as the solar array seems hardly adequate in size to change anything, let alone a 20,000mAh battery.

    2 or 3 years ago I bought something like that in Aldi, not waterproof and only 10,000mAh but I got it for only $9,90, I thought it was a pricing error and quickly grabbed the last 2.
    I didn't buy it for the solar surface but the capacity/price ratio.
    I tried it once directly in the sun and an hour later I decided never to do that again because it got far too hot for my liking and what I consider safe for standard Li-Ion batteries.

    That little array has about 1W, the battery has 20Ah x 3.7V capacity = 74Wh.
    Roughly 10-12 full sunny days to charge at an expected 6-8Wh a day. By then the battery capacity would have lost some Ah due to prolonged heat exposure unless you charged it in colder parts of the world.
    This era of thoughtless consumption must end so we can encourage a world of creative geniuses rather than consumer idiots.
