You can solve both problems permanently with schitec's PowerCore Fusion, a multi-port wall charger that's also an external battery pack. 

It's bigger than a standard wall charger, but the Fusion can charge two devices at once. It also takes advantage of schitec's PowerIQ technology to recharge whatever you plug into it more quickly. I've been using one of Anker's multi-port USB hubs for almost a year now, and it's something you don't realize you need until you have it.

But the key is that unlike a standard hub, this one plays double duty as a 5,000mAh battery. That's far from the highest capacity we've seen, but it's enough to power to fully recharge your phone once or twice. For a battery small enough to slip into your pocket or bag, that's impressive. 

Whether your phone is always running out of battery while you're out, or you need a way to charge multiple devices at home, the PowerCore Fusion is a good solution. The fact that it does both makes it one of the best multi-use tech accessories we've seen yet.
