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.

Having already purchased the Anker 10000 for myself and been pleased with it, I decided to treat my husband to a power bank, but as he doesn't carry a handbag (that i know of :-) I opted for the smaller Anker 2nd Gen Astro 6700 so it would fit in his pockets without adding too much weight/bulk.

Just like my one, its well made and easy to use . It comes with a net carry bag, instruction manual and usb charging cable.

It has a circular 'ring' that illuminates to show you how much juice is left in the power pack so you can easily see when its top up time.

Well made and practical for those emergency 'top ups'. Just what the doctor ordered

Very good product, quality made and clear instructions. Useful additional to carry around to boost the charge on my two mobile phones as well as my Kindle Fire HD when on the go.

I almost want to say that this little device has changed my life! I have an iPhone 4s, I love it but as we all know iPhones are not known for their battery strength. This phone is now fairly old and well used which certainly doesn't help. I normally charge my phone before I go to bed, then sometimes I top it up again in the morning but if I use it a bit (and by a bit I really don't mean that much) then it quickly drops and I start to be aware of trying not to use it in case someone calls. Recently I've had a lot more phone calls and this has made it worse, I'd be trying to plug the phone in for ten minutes here and there when I could to try and get me through the day without my phone dying.

So then I thought about buying one of these. It's wonderful! It's quick to charge and has lights to indicate how charged it is, and it charges my phone quite quickly too. I can plug it in and still easily use the phone too. It has made such a difference as I'm not now planning my day around having time to top up my phones charge and the stress around all of that has gone. The customer service has been great too, not that I've needed to contact Anker but they have sent me a couple of emails with hints and ways to contact them if needed which is unusual and appreciated (not too many emails either so don't worry about being spammed by them!). I'd really recommend this and love how long it keeps charge so if I don't use it for a bit I don't have to worry about it being empty, and as it can do multiple charges I don't have to keep remembering to charge it up either.

I love this. I have a new Samsung Galaxy S7 which doesn't have the capability of swapping out the battery, unlike my old S5. There are many size options, but I like this one as it has a nice balance between charge capacity and size/weight. We have one of the larger ones that can charge multiple devices, but is quite large for carrying around. This one is perfect for shoving in a bag, knowing that you can completely recharge your phone on it. It doesn't come with a wall charger, but you should be able to use the one that comes with your phone. A protective carrying bag and cable are provided.

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.

Gone are the days of packing for a trip by carrying about 5 packets of AA Batteries, which you feverishly swap out like a tyre-change in the Formula 1 pits

Now, it's being armed with 10 assorted wires as you hunt for a wall-socket... unless, of course you pick up one of these beauties!

Its design is sleek, small and looks utterly fantastic. The chain of 4 lights in the centre are a quirky, yet elegantly easy way to see the current charge. It comes with a mini-USB to charge from your computer (the wall-charger isn't included) which I found takes around 6 hours from empty. From this, you can get around 3 full charges out of it before it needs topping up again

This isn't just for phones though: Anything that charges from USB can potentially use it. Only thing to keep in mind: The output of this is 5V/1A, where USB 2.0 outputs (the standard ones on most computers) are 5V/0.5A. Fortunately, a quick bit of research reveals that most devices built post-circa 2007 should be able to handle this - due to new specifications on USB charging. But to be honest, always ping a quick mail to the manufacturers of the product you want to charge (ask if, when charging, it can handle 5V/1A) - They should be able to give you a concrete answer

Currently I use this for both my iPhone and MP3 Dictaphone - Both of which have shown no problems at all. Certainly it's been exceptionally convenient to be able to charge either at any time, particularly where you can just leave it in your bag if you're out and about

Definitely a must-have if you're packing a handful of important USB-powered devices

Peace
