What's the point of carrying around a backup battery that's larger than the smartphone it's designed to boost? It defeats the purpose of carrying a pocketable device in the first place. When it comes to backup batteries, slim is the only way to go, and with a set of pop-ports that keep its USB ports free of dust and crap, Paick's Noble will easily slip into a bag or pocket.
The Noble's 6,000mAh battery is large enough to bring three iPhones back from the dead, or completely recharge an iPad or other larger tablet. At half an inch thick it's not the slimmest battery you can buy, but with two USB and a microUSB port, it could be one of the more useful tools in your bag. And, with an introductory price of just $50 it's a ridiculously affordable way to ensure you never find yourself with a dead phone. More here.
