Around 6-8 hours or so!
Sorry, there was a problem. Please try again later.I think it took about 4 or 5 hours with a 2 amp charger.
Sorry, there was a problem. Please try again later.Out of the box it was only partially charged. There are four blue lights indicating the charge and if I remember correctly only 2 were on so I’m assuming it was about half charged. I didn’t time the initial charge but remember It was slow. Maybe a couple of hours to see a third light on. I just left it charging overnight and the next morning it was fully charged. Unit stops charging when fully charged. Also, charging a iPhone or iPad from the device takes time. I didn’t buy it for the speed of charging or recharging but to have as a backup while backpacking so I would be just plugging my device into it while sleeping. Hope this helps.
Sorry, there was a problem. Please try again later.This charger takes awhile to charge .... I would say at least 24 hours maybe a bit more.
