Aukey via Amazon has a few USB chargers to keep your devices juiced up while on-the-go this holiday season. The Aukey 20,000mAh Portable Charger External Battery in black is only $17.99 Prime shipped when you use the code QBI8OGMD at checkout. That's $12 off the regular sale price and the lowest we've seen.
It detects the input current of your devices to maximize both compatibility and charging speed. Also, it can charge the iPhone 6 at least 7 times, and deliver a full charge to an iPad Air. There are four blue LED indicators to display the remaining power and a built-in flashlight for dark or low-light conditions.
