This is an amazing concept ! You don’t even need a Charger anymore, just plug the battery itself in the computer, and boom, it’s charged…
On the first two pictures you’ll see there is a little light on each battery. When it’s on, it means it’s charging. If it’s blinking, then it’s 90% charged. Once it’s charged, the light turns off…
Simply brilliant ! More information at USBCELL.COM !
PS: 1300mAh, pretty good. I hope they will have 2500mAh soon ! Any questions in the comments ?
