Anker’s ubiquitous Astro series of USB battery packs are some of the most popular items we’ve ever posted, but today we have one of the first deals ever on their brand new PowerCore charger.

The 13,000mAh pack features high quality Panasonic battery cells and can output 4 amps of power through a single USB port (or split that power between its two ports), meaning you can charge two tablets or phones at full speed simultaneously, or even charge up a high-draw device like a new MacBook at acceptable speeds. The older 13,000 Astro E4, by comparison, can only push out 3 amps. The PowerCore also comes with a new matte design that should resist fingerprints and be a little less slippery.

Of course, sometimes you need something a little more compact to carry around in your pocket, and this 3,000mAh Olala option fits the bill for just $3. [OLALA Y1 Power Bank 3000mAh Portable Cell phone Mobile External Battery Charger, $3 with code 674QTPE6]
