Duracell's newest USB powered charger is a jack of all trades when it comes to what it can be used with. From mobile phones, tablets, and e-readers, it's ready for anything that needs juice after being wirelessly charged atop a myGrid charging slab.
Also able to be charged via USB as well, this 35 dollar device is slim and tiny for stuffing in your pocket or suitcase for power on the go. The amount of time it can power a device varies of course, but they list mp3 players at around 30 hours, smartphones at four hours, and e-readers at 100 hours. Look for the myGrid USB charger to hit shelves this holiday season.
