Anker enjoy a great reputation and it's not hard to see why. The Astro E5 has plenty of power to keep your devices charged whilst out and about. Construction is great. The outer casing is, though, a fingerprint magnet which is why I went for the white version - they don't show up.

Anker products come with an 18 month guarantee which shows the company has faith in the reliability of its products.

to start with this was brilliant, I took it fishing and kept my phone and a friends phone going all weekend. after only a couple of months it started to become clear that the battery life was much lower. after 6 months it is now sat in a draw not used as it is of little use.
one problem I had with it from nearly new is although it can charge ure iPhone or other devices several times it was taking nearly a day to charge!

Update 28.06.16;- i have increased my review to 3 stars due to the amazing customer service, even though i submitted my review over 12 months after my purchase, they have contacted me to send me another due to the issue with the first item. I will update the review again once i have received the item and been able to test it out

Great product for charging away from home. I use all the time when out camping. On a full charge it can charge my iPad mini twice and my smartphone 5 times. Also it has a very bright light on it which comes in very handy!

I have been looking for an external battery for ages and l never really got round to ordering anything. So I sat down and decided to get it sorted out, I found this Anker product.

I am a fan of Ankers products, I have the high power USB charger of theirs and its been great so I decided to take the plunge and order it up. I have not been disappointed, its fantastic and charges my Galaxy S4 work phone in next to no time, it has also got me out of trouble with my iPhone 6 and I will be taking it away with me next month but I'm confident I'll have no issues with it.

I was supplied a sample for test and evaluation, and I promised that my review is fair and honest.

I own both the Anker Astro Mini and the Anker SlimTalk. I use either of the two batteries for everyday commute to and from work. My iPhone 5 is a battery hog and I need any of the above batteries that are both lightweight, as backup. However, the above batteries can only supply 1-1.5 full charges to the iPhone. Because of this limitation, I need a larger backup battery for long travel like (e.g. long haul flights, long bus/car rides).

I received the Anker Astro E5 battery in time for our Adirondack vacation. The dual ports really come in handy as you can share the battery with your companions or charge two devices simultaneously. The kids all brought their gaming device and iPads, and us - our Smartphones. We can not rely on the car charger as it can only charge a GPS device or smartphone and not an iPad. I'm glad that the Anker Astro E5 can supply as much juice as to charge an iPad along with another Smartphone or a gaming device.

The Anker Astro E5 is a bit heavier than my other Anker external batteries. Tested a fully-charged E5; it can supply 2 full charges to a Smartphone, 2 full charges to an iPad, plus 1 full charge to a gaming device and a bluetooth headset. Pretty impressive for a device that is not as heavy as I was expecting it to be. I also believe that this external battery will also come in handy in cases of emergencies, hurricanes and blackouts. It also comes with a LED flashlight feature which you can use to locate adapters and connections while in the dark (night time travel, blackouts, etc.).

Size and weight is not as bulky as my old Zagg external battery. Size is almost equivalent to a regular 2.5 inch external hard drive.

After purchasing a number of Anker chargers over the last few years I have to say this one is the most robust so far. Much larger than the others it's not really pocket sized at 15cm long. The slightly smaller previous model did 3 or 4 charges on a Samsung s4 but this one apparently does 7 or 8 although we have not had it that long to test that it certainly looks probable. They are just a MUST HAVE these days for smart phone users and my ipad mini works well too. I use my other one most days for backup charging when I am busy.
This one was bought to give to my son for his birthday after his mate blew up the old one by plugging his into my sons ... to charge it!!! Not a good idea. My son works long hours and uses a rucksack every day so the size is not an issue. If you want pocket sized versions we have purchased three of the smaller bullet shaped ones from anker for the nephews and nieces christmas pressies. What could a teenager want more than all day mobile access! They were chuffed and thought Aunty was really cool for being so clued up.
To be honest, if I am ever short of an idea what to buy someone, I've come back to one of these various models from anker. They definitely give value for money totally useful daily gadgets and piece of mind with the guarantee its a no brainer in my opinion. Anker have always had excellent customer support too, hence my willingness to post a review again for our new purchase they deserve it. I've only ever had one break once but I dropped it on concrete from a great height! This new one actually looks like it would survive that though!!!
So to sum up, you can't go wrong IMO with anker chargers just check the sizes and capacities, there's quite a few to choose from, to make sure you've got the most charge and the appropriate size. Thanks anker for another excellent product and a happy birthday boy!!
