Today only, Monoprice is offering one of the best external battery pack deals I’ve ever seen (and I’ve seen more than can possibly be healthy), assuming you own an iPhone.

$15 gets you a big-but-not-too-big 9,000mAh battery pack, plus two Lightning cables, one of which is a pocket friendly 4 inches. $15 would be a great price for the cables by themselves, so the battery is basically just a cherry on top. [9000mAh, 2.1A Battery Pack and Two Apple MFi Certified Lightning™ Cables, 4-inch and 3ft, $15]
