The portable power bank is really good. Didn"t even charge it before use and got 2+ charges from it before I had to recharge it. Highly recommended

Just purchased... and review updated.4 Aug 2013

By Tomcatuk

Size Name:5600mAh|Amazon Verified Purchase

Only just got this, mainly to charge up a gopro battery, but thought I would charge up my iphone5 as was about to go out and no time to plug into mains charger, as it does not come supplied with the latest type (lighting connector) I took the iphone lead with me and plugged it in... great its charging... two minutes later the charging stops and you get the yellow warning triangle displaying on the iphone5 that this is not a compatible charger and so will not charge your iphone5 despite the product claiming to charge it.

Update: After writing this review I was contacted by Anker who were most concerned about this not working with the iPhone 5, to cut a long story short this product now gets FIVE stars and the same for the Anker support via email, there is sometimes a slight delay in getting a reply due to the times zone but it was sorted out and Anker sent me a replacement unit via Amazon.
I plugged it in to a half charged unit and no more warning from the iphone, charged up the iphone which was on 67% to 100% in no time at all, can not recommend this company and support highly enough, if only all support was like this... they also told me no need to return the old unit so keeping that as it works on the Gopro hero 3.

A must for Glastonbury 15 July 2013

By Michael Drinkwater

Size Name:5600mAh|Amazon Verified Purchase

I brought this to use on my iPhone 5 at Glastonbury. It gave three full charges and my phone lasted from Wednesday morning to Monday. It does not come with the iphone5 lead but then this also sells on Amazon for just over £2.

Brilliant little gadget 21 July 2013

By Andy

Size Name:Mini 3000mAh Black

Was going to go for a the bigger 10000mAh battery but thought I"ve give this a try first because it looked like a nice size and a good compromise.

Very happy with my purchase. The battery looks great, it"s very small and comes with a nice little bag. As an iphone 5 user I knew I wasn"t going to get an adapter included (it would be nice if Anker do in future) but it wasn"t an issue, I just use the ridiculously short cable that apple supply with the phone.

Anyway, I charged it up straight away from the mains and did some tests in my first week with the Astro mini. First test was to top up my phone each evening until it was 100% and NOT charge the mini in between topups. I managed to charge it up on 3 consecutive nights from 60% to 100%, 50% to 100% and 53% to 83% before the mini was depleted.

The next test was to let the phone battery go completely flat and see how the mini coped charging it from 0% which I believe is harder to do. It coped well, I got one full 100% charge and then the next evening I charged the phone from 66% to nearly full, I think it was about 88%.

So conclusion is you can get about 3 half charges or about 1.3 full charges on an iPhone 5 with light use of the phone whilst charging. So in my view this fit"s the bill perfectly for me for weekends camping or long distance walking where I might need to juice up my phone because I use it a lot as a camera. For the price and small size, this is perfect for my needs.

Nice one Anker! I would definitely purchase your products again.

Brilliant piece of hardware 21 Jun 2013

By Claude

Size Name:5600mAh

Received this as a Father day"s gift because the USB port of my car seems to be incapable of charging my IPhone. Works like a charm and is for me personally a life saver in those situations where you need to charge your phone with no socket in sight. Easy to charge and plenty of power for 2-3 charges. Love it!

Great backup battery 30 Aug 2013

By boonster

Size Name:Mini 3000mAh Black|Amazon Verified Purchase

The unit arrived within a few days of order and is very compact.

I used it to provide backup power for my Garmin edge 800 on a cycle tour through Normandy. It will charge the unit whilst in use if used with a genuine Garmin lead and is small enough to be taped to the handlebars.

Would recommend as ideal for someone needing portable power whilst travelling light.

A neat piece of kit but the carry pouch could be better 19 July 2013

By James H

Size Name:5600mAh|Amazon Verified Purchase

I"d been thinking about getting a back up battery pack for a while but never got round to it. Then when I found myself on a business trip with a dead iphone and no means to charge it while on the move I decided to buy one and after a fair bit of research settled on this one.

It"s neat, not too heavy and it comes with a variety of connectors. It works. What more could you want? Well I"d like a carry pouch that doesn"t have a drawstring because no matter how tight you pull it, one of the adaptors still slips out the top of the pouch. So far I"ve found them in my briefcase or bag but that"s just lucky. One day I"ll lose one. So a pouch with a zip perhaps or similar?

Otherwise it"s a cracking product.
