  1. yea solar battery banks are just gimmicks. youre just better off finding a higher capacity power bank for the same money.

    Most power bank batteries are usually 3.7v while the usb outputs 5v. the key word is "most."

    assuming this bank does use a 3.7v battery,the general rule of thumb is divide the capacity by 3 then multiply by 2 as 3.7v truly run at about 2/3s efficiency. so in this case 10k/3=3.3k. 3.3k*2= 6.6k. so realistically youd get up to 6600mah of actual charge and at thats 100% efficiency which is never the case,but its a good benchmark.

    to put it into perspective a 10000mah bank from a reputable company can charge a dead iphone 6s 3 times with a bit of extra juice left.

    For a dead samsung galaxy s7 edge…almost 2 times. And no that doesnt mean iphone is better because a 10000mah powerbank can charge it more times…it just means that the s7 edge has a much larger battery.

  2. I have similar size solar panel, it outputs 6V & 20mA (in real test no direct sunlight), after math & test on my I phone, it takes 3 days to fully charge 1400mah battery. To charge 10k mAh battery it would be around 7 times longer = 21 Days nonstop sunlight.

    Im just saying, dont bother with the solar, just buy a normal power bank.
