A fool and his money are easily parted.


It's your average $10‐20 china junk that's marked up to a premium "4 patriots".

Heres what I bought and use.
Works as good as every other no name china battery pack. Biggest scam is overselling the battery sizes.
This one is legit.

I looked at these in the past.
When you do the math, onboard solar panel is so small that it will take 5-7 days of full sun to recharge the battery pack.

Yup, at 1.5W under the best conditions it's gonna take forever.

I'm not sure what your intended use is, but I bought one of these for backpacking to keep my phone charged. Solar sucks in Western PA.

Figured I'd show the math just to make it clear.

The panels on those units output 1.5W at around 6VDC. To find the current we divide 1.5/6=.25A or 250mA

The battery in the OP's post is an 8000mA/H. To find the time, and since we're using like units, we can just divide 8000mA / 250mA = 32 hours.

That means you'd need 32 hours of perfect sunlight to fully recharge the battery pack from the supplied panel.

That is of course a perfect model without account for any other losses. It would actually take more than that.

How long if I put it under a sun lamp ?

Longer than plugging it in next to the lamp.
