External battery packs are pretty simple. Unless you're specifically looking for something small or stylish, you generally want the biggest capacity for the cheapest price. One Amazon listing is delivering just that today: a 10,400mAh battery for $19.99. This Lumsing model should charge most Android smartphones at least three times over, more if you've got a smaller or older device. It doesn't look half bad, either - the description says it's designed to look like a harmonica, but I wouldn't recommend blowing into the holes.

Gadget lovers tend to accrue all kinds of electronic detritus on their desks, night tables, coffee tables, and any other flat surface where you can put down a tablet. And for keeping that detritus charged, there's nothing more convenient than a USB outlet adapter... except an adaptor with more than one USB port. If you find yourself short of places to plug in, Amazon is offering a Volmate 5-port charger for just $12.49 after a coupon.
