Anker Astro E5 15000mAh

The Anker Astro E5 is an easy-touse power bank that offers pretty good value and useful capacity, without being too big and heavy to take on your travels. With 15000mAh on offer you can expect around 10500mAh to be available to your devices – roughly 30 percent is lost from the premium LG battery cells inside through heat generated and voltage conversion. This would charge an iPhone 6’s 1810mAh battery nearly six times, although Android phones typically have larger-capacity batteries so expect fewer charges.

The Anker Astro E5 very much reminds us of the RavPower RP-PB13 Deluxe, a £23 14000mAh power bank that has a similar rectangular design, encased in black plastic with a silver-painted central band. This Anker has a gloss finish that’s a magnet to fingerprints, however, and its silver power button and four status LEDs stand out more than the smaller black button and blue LED strip seen on the RavPower. There is little difference in their size and weight, although we prefer the RavPower’s design.

The specs are incredibly similar, too. Both feature 1A (5W) and 2A (10W) fast-charging USB outputs for simultaneously charging a phone and tablet, although here they sit either side of the LED flashlight rather than to the left. And both have a 1.5A (7.5W) Micro-USB input for refilling their own batteries. There is really very little separating between the two, and your decision will likely be swayed by their design rather than the small differences in price and capacity. This Anker’s 18-month warranty is also attractive.

Neither Anker nor RavPower support advanced features such as passthrough charging, so you won’t be able to simultaneously charge your phone, tablet and power bank without using a pair of mains sockets.

Verdict

The Anker Astro E5 15000mAh is a decent power bank at a good price.
