 Slick Looking External Power for Every Mobile Need May 9, 2013

By Joseph Siu

Color Name:Black

Since Anker gave me this product in exchange for my honest feedback and review, I decided to take the Astro E4 power bank through its paces to see how it performs. I was quite pleased with the results; this is one solid external battery. Details below.

The battery came in a nice-looking box along with a carrying pouch and an interchangeable-head USB cable; the cable came with three adapter heads: Micro-USB, Mini-USB, and iPhone/iPad (30-pin). The power bank itself has a smooth, black plastic shells and is quite elegant-looking with its chrome button and silver-colored frame. The unit has 4 bright, blue LED lights that reveals roughly how much battery life is left. The Astro E4 is somewhat heavy, but it is expect of a power bank of this large a capacity; the best way I could describe it is probably holding 2-3 rolls of quarters in your hand (not bad, right?). Due to its size and weight, this external battery is a perfect companion for your day-pack (messenger bag, backpack, purse, etc.)

In terms of real-life performance, I ran tests using an iPad 2 and a Google LG Nexus 4, on multiple charge cycles. After charging the power bank to its fullest, I was able to get around 9200 mAh out of the the unit, which is around 71% of the stated capacity. Almost all external batteries perform below stated capacity, and some by a lot, so getting this amount of juice out of the Astro E4 is pretty decent. It is important to note that the charging devices were left on and drawing power for Wifi and cell signal; the actual capacity is probably even higher
