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.

Bought four Anker 2nd Gen Astro Mini's for Christmas gifts. My daughter's charger just exploded in her room. Loud banging noises and looked like fire works for about 7 seconds, lots of smoke and a horrible smell. Burned the wall and carpet. Anker charger still very hot 15 min after it exploded. Thankfully, she is ok. Has anyone else had this problem?

Love it! Initial charge time for my Anker Mini was a few hours. Once charged it worked exactly as described. I was concerned that it would be cumbersome to carry, but it is surprisingly light and a convenient size, and durably made. Included pouch is nifty and a major plus. In addition to the Anker Mini, I purchased the Innovative Digital 5" lightning cable to charge my iPhone 5. The mini lightning cable works great AND fits in Anker pouch! See Innovative Digital USB to Lightning compatible Cable (5 inch). I looked at other round mini chargers, but they did not have on/off switch. I don't yet know how long it will retain its charge, may update this review later. So far, very happy with this purchase. Fast delivery.

I bought it anyway and I've used it twice already. There's been two nights when I've forgotten to plug the charger into my Nexus 4 and I had class at 8AM the next morning. My phone was almost dead, but all I had to do was bring the Astro Mini with me. Carrying them both around while the phone is charging is easy. I put the charger in my back pocket and phone in the front pocket, while still connected. The spiraled cord is long enough to allow you to use the phone while the charger remains in the back pocket. It gives my phone a full charge in about 2 hours.

I use this primarily for travel with my Samsung Galaxy S3. On average, it takes about 5 hours to charge to capacity, and stores slightly more than one complete battery charge for the phone. I've been using it consistently when traveling, and while I do wish it stored more charge, for the size and price, it's been very useful.

EDIT:
Anker Direct saw my review and sent me a 5600MaH unit to keep, which I'll review separately, but I will mention here that it is really fantastic. This is one of the best customer service experiences I've had. They kept in touch with me throughout the process and even suggested I keep the smaller model. Really a fantastic company to work with, highly recommended.

It may not be the latest and greatest generation of Anker products, but it doesn't need to be the next generation to function well.

I'm gearing up towards my first Android phone. Having dug my heels in about switching from Blackberry (business phone), I'm finally breaking the blackberry ball and chain, and I know having a spare charger is essential, especially with the new device fascination that will likely eat up battery charge. While I wait for my new phone to arrive, I tried out this charger, and it was able to charge my blackberry in short order.

It also comes with a nice quality mesh bag, so you can keep the charger and the cord together in your bag/purse/backpack. It's attention to details like this that make me look to Anker first for tech gear.

I'm a UPS driver working very long hours and stream music and talk radio from my iPhone to my bluetooth headset to help me make it through these super long Christmas days. The problem was that my iPhone's battery would run very low later in the day. This is no longer a problem thanks to Anker, I just hook my phone up to the Anker battery pack and let it charge my phone back up. Every couple of days I just connect the battery pack to the USB port on my computer, let it charge back up and I'm good to go for 2 or 3 more days. I like this product so much I bought one for my son for Christmas as well!

This is an ideal battery for smaller devices like phones, mp3s, etc.

I recently moved to a big city and running errands all day without a car means I either have to make sure the phone is fully charged in the morning or buy coffee in order to borrow electricity from a cafe. This charger is pretty much the perfect size and weight for my situation, or any for that matter. A fully charged Astro Mini will replenish an almost-completely-drained iPhone 4S to 100% the first time and a little less than 50% the second time. Though it's always a good habit to charge your phone before bed...but on the rare occasions that you forget to or need to have battery consuming applications (like GPS or Bluetooth) running for a long duration, it's a life saver.

I took off a star for the following reasons:

1) The instruction states that "The red LED indicator will flash continuously while charging. The red LED indicator will TURN OFF AUTOMATICALLY when the Astro Mini is fully charged." I find it not being the case for me and it took me a couple times to realize that once mine is completely charged, my indicator will stop flashing and stay fully on instead of turning off. Not sure if mine is defective, or it is an error on the manual. However not a huge deal.

2) We were shown a retractable adapter cable with the package but I received one of those coiled ones instead. The retractable cable would be more useful for me because it is longer (and adjustable) so I can pull my phone out of my pocket without having to take the charger out as well or disconnect it. I understand that companies do not always control the type of accessories that their distributors include on their packages so I probably just happened to not get the one on top of my list.
