I've got so many wall chargers in my box of gadget accessories that I don't even know which ones originally came with which device. Some of them are not powerful enough to keep up with my iPad Air. If I accidentally grab the wrong one, I'm stuck with a trickle charge that won't even bring me back up to full overnight.
The iClever charger uses smartID technology to identify your device and provide it with the correct amount of juice. With two USB ports, you can charge multiple devices at once without having to fight over who gets the wall socket first.
