AnkerDirect via Amazon offers its Astro E7 High Capacity 25600mAh 3-port 4A portable external battery for $79.99. Applying coupon code ANK4999S drops the final price down to $49.99 shipped. That’s good for nearly 38% off the regular price and the lowest offering that we have seen by $10.

Anker’s Astro E7 power bank has enough juice to fully charge a 12-inch MacBook when it is powered down, or to maintain its built-in battery levels while in use for an extended period of time. You’ll need a USB A to C cable to do so. It can deliver up to four amps on three ports at a time, and can recharge three iPhones or iPads at the quickest speeds simultaneously. The Astro E7 will recharge an iPhone 6 ten times or the iPad Air 2 twice. It also includes a built-in LED flashlight and ships with an 18-month warranty.

If you’re looking for an ideal companion to keep all your devices charged on the road, this is it. Nearly 1,000 Amazon users rate this power bank 4.7/5 stars.
