About USB Battery Packs

Wired in calls for powered up! The average person carries around at least two or three USB devices with batteries—a phone and a tablet are normal—and a good USB battery pack can go a long way towards preventing loss of connection. What's a USB battery pack? It's a portable, rechargeable battery pack that recharges USB devices. That is, it's a portable high-capacity battery pack that can recharge your device if you don't have an outlet handy. A USB battery pack AA also recharges AA batteries. The USB emergeny power pack holds much more juice than your onboard battery in the device itself. Frequently sold on eBay, the packs vary in total energy capacity, how many USB outlets they have (which determines how many devices you can charge at once), and the oomph of zap from each USB outlet, so which is best for you will depend on what you're carrying around. It's a great way to be sure you make that important conference call.
