>>2505364Mine takes 2-3 hours on my truck's usb charger, from dead to solid-green.
The few times I used the solar charger, I'd plug everything in and let it sit in the sun all day long. Light still red, 6+ hours later.
Plug it into the charger in the truck on the drive home, 2 hours later it's blinking green, half hour after that it's solid/full-charged.
So basically the solar charger didn't do a fucking thing but turn the red LED on.
For the size and weight of the charger/solar panels, I can carry a lot of charged batteries.
