    Does anybody here use a solar cellphone battery pack?

    My son had one of these that he doesn't use and gave it to me.

    I'm wondering if indeed I can charge my cellphone with it. I haven't tried it yet but it might be convenient to use when I'm not near a wall outlet or the car. I have it sitting on the window sill now to see if it recharges.
    I have several used cellphones for sale in my Bonanza booth.

    Looking at the numbers, it says that it is a 300 Ah battery. A car battery is something like 50 Ah. This is not believable. This is cheap Chinese junk. They are selling it for $15. Not possible that it has anywhere near that capacity.

    That said, it might work at whatever its capacity really is. It is plausible that it is really a 5-10 AH battery pack. That would charge an average cellphone a couple of times from 20% to 100%.

    If the solar charging number is correct at 200 mA, which is doubtful, it would take over five full days of direct Sunlight with the Solar cells pointed optimally directly at the Sun to charge a 7 AH battery pack. It might come in handy in a pinch for something rather than nothing in a desperation situation.

    I had one where the solar charging was super slow and the battery actually exploded inside the casing. Made by the same people.

    But it's marked down from $50!

    When you think about it, you have to leave it out in the bright sun to build a charge but not in a place where someone would steal it. Like on the dash of a car, but then why not just use a 12 v charger? The only place I could see it being useful is out in the bush (off the grid) in some place like Papua New Guinea, where you could leave it out in the sun all day and charge your phone (or other USB device) at night.
