Anyone tried this? Any ideas of how quick/reliable this would be able to charge a device?
Never tried it, but am looking for some more info on this. Anyone with resources please post RL's!
I would love to try it, but it just doesn't seem like it would have enough juice to power anything, much less give it a charge.
Most plug-in USB chargers have an output of 1A for smartphones or 2.1A for tablets/smartphones, so the output of the batteries should be good enough. I guess it depends on the output of the solar panel as to how long it takes to charge the batteries. Typical 4V solar panel spec here. I'll let someone with a better knowledge of electronics work out what that means!
The original link is someone's copy of an instructables article. I've added that as a related link above. The writer of that project gives links to a couple of better versions. I've added those too.
My guess would be really slow. Like 12 hours in the sun to charge a phone.
Yeah that's what I was thinking
Not a smart phone, not at that size.
Yeah I would guess like 25-50% of a smart phone (approx 1000 mAh)
