Bests & Worsts Reviews from Amazon

The Anker Astro Mini is a nice small back-up power supply to keep your power-hungry iPhone running. I ran a test with my iPhone 5 to see just how much juice you could expect. I drained my iPhone 5 down to 10%, then used the Astro mini to recharge it to 100%. The Astro still had some charge, so I drained my iPhone 5 down to 10% again, then used the Astro mini to recharge. This time I only got back to 40% charged before the Astro was done. The way I look at it, you can get ~1.2 full iPhone 5 charges from one Astro charge. Not bad and just what I needed to keep running thru a long day. I recharged the Astro from my computer USB port. It took ~ 6 hours to fully recharge (charging light turned off). It might charge a little faster with a plug-in charger, but you should plan on 6 hours (or overnight) to fully recharge. The instructions are simple and the carrying bag is fine. There are a number of adapters for included charging cord. Unfortunately, the iPhone 5 “lightning” connector is not one of them. If the lightning connector was included, it would be a 5 star.
