Product Description

With such massive capacity, in such a compact package, the Anker® Astro E4 is perfect for flights, road trips, or just any time you're away from an outlet.

Enough power to go around.
Marooned? In transit? Forget your OEM adapter? With the Anker® Astro E4, prolong your battery life multiple times, wherever you are. Holding enough power to charge a smartphone 3-6 times (depending on your phone's battery size), keep your gadgets going for days and still have juice left to share.

Strong but never slow.
In addition to capacity, the Anker® Astro E4 sports two concurrent, high-speed ports. So whether you're charging an Apple or Android device, you'll get the most out of your technology. We've also included connective adapters to ensure compatibility with most devices.

Designed around the details.
Just because the E4 packs a punch, doesn't mean it can't look nice. We went with a smooth, ebony finish to keep you traveling in style. Simple, unobtrusive features, such as one-touch status LEDs and a built-in flashlight, give you everything you need out of a battery without sacrificing aesthetics.

For optimal use.
• For simultaneous, max-speed charging of your Astro and other devices, check out Anker's new 25W 5-port wall charger or dual-port 24W car charger.
• Compatible with all Apple and Android smartphones, tablets and other 5V input USB-charged devices. The iPod nano, the Samsung Tab2, Asus tablets (not include the Nexus 7), the LG G2 and some GPS and Bluetooth devices are not supported.
• To ensure complete safety and best performance, we strongly recommend using your device's original cable, a third-party certified cable (such as MFI) or our included cable.

4.0 out of 5 stars Great But Had Niggles 13 May 2013
By C. M. Cotton TOP 100 REVIEWER VINE VOICE
Colour Name:Black
Anker gave me this product free to test so that I can give my honest feedback.

I have had a number of Anker products to review recently and I have rated them all as 5 star products. This item is a brilliant idea, it is in essence a rechargeable battery that charges other items, such as my Android phone. The product is quite small and relatively lightweight given the capacity of its charge. It is made from quality black plastic, with a chrome casing around the outside, which makes it look and feel superb. There is a chrome button which turns the unit on and off and also switches the internal LED flash-light on and off. Above the button are 4 blue LED lights which indicate the amount of charge left in the unit. There are 3 outlets, 2 USB ports and one Android/Phone charging port. To use you simply charge the unit using a USB port and then use the included cable to charge the item you want to charge such as a phone. On my test, I charged my Sony Xperia phone from empty to 100% charge in 1 hour 20 minutes, so equating to almost the same charge rate as plugging it into a socket. This charge also hardly dissipated the internal battery of the unit. I think the units' battery once fully charged, will allow 7 full charges of my mobile phone, giving the unit an enormous capacity.

I am very impressed by the unit and how it looks and the quality of its construction. As always the item is backed by Anker's 18 month warranty and helpline. For the first time with an Anker product I have two minor concerns. Firstly the instruction book is far to small and was difficult to read. Secondly the On/Off switch can be turned on too easily, resulting in the LED torch illuminating and so discharging the battery.

5.0 out of 5 stars This is a must have travel companion! 20 Jun 2014
Colour Name:Black|Verified Purchase
This is an excellent Power Bank that holds multiple charges for my devices!

I was a bit sceptical when buying this product as there are multiple reviewers saying the button is a little to easy to press and this could result in the torch turning on and draining the battery. I have not experienced this however have been keeping the charger in a small pocket in my bag for good measure.

The capacity of this device is massive! I can be away from power for several days and this charger will still have juice, despite charging my nexus 5 multiple times. The pouch that the charger comes with is a nice accessory that has just enough room for a usb cable to be stored in.

My only negative is that its very glossy and prone to fingerprints but that really doesnt affect the charger itself so I won't deduct any stars for it.

All in all, a great charger and essential for travelling!

5.0 out of 5 stars Does exactly what it should - Superb 7 May 2014
Colour Name:Black|Verified Purchase
I had read a number of the reviews before buying the Astro E4 and hoped that I did not have any of the problems experienced by some of the reviewers. I have to say that It has performed superbly and on a recent holiday to Peru, provided plenty of power for my Ipad Air and Camera. It always charged my kit quickly, even with the 1A port and I had no trouble recharging the E4 itself. It worked OK with a travel adapter and the electrics in Peru. It was particularly useful when one of our party had not got the correct travel adapter and I had to lend her the E4, to charge her Iphone a few times. The capacity seemed to be substantial although I did re-charge it at every opportunity, so I never totally flattened the battery. The only issue I had was with the switch, which was very easy to catch when in a bag resulting in the flashlight being turned on a few times. I just had to remember to be careful how I placed in my rucksack. Overall A very useful piece of kit and at a price that I thought good value.

5.0 out of 5 stars Bulky Charger but holds charge well 6 May 2014
By Grace
Colour Name:Black|Verified Purchase
After being mocked for the size of this charger, it is heavier and larger than an Iphone. I soon became the local charging point for my friends phones in the beer garden.

This has only been running off its charge from the box and has charged lots of Iphones from various states of emptiness, from dead to around 65%. It still has charge in it which has surprised me. I presume that it will take a while to charge up but that is easily offset by how long it lasts whilst out.

The first one i purchased was not delivered as it got damaged somewhere in transit. I had to re order one rather than be sent a replacement which was a pain, however Amazon did deal with my complaint swiftly.

This is definitely not a pocket charger, it is ideal for women who carry handbags or men with rucksacks or the like, as it is quite large and heavy.

I can see this coming in handy on long car journeys, camping, flights etc.

5.0 out of 5 stars Great for festivals! 1 July 2014
Colour Name:Black
Bought for the festival season and it packed enough power to keep mine and my girlfriend's mobile phones charged for the whole of Glastonbury! I'd say it can change a phone from flat to full around six times.

I've read some reviews about issues with charging this battery. It does take a long time to charge (around 10 hours) and that's using the 2.1A iPad 3 adapter. I'd imagine a few people have problems with adapters that aren't putting out enough current.

The battery is fairly heavy and big, not really something to carry in your pocket all day, but did go in my girlfriends handbag...

The button on the battery also operates the torch, again as a few reviews have said this can accidentally be operated, even though it is slightly indented. It requires a double-press to switch on and off. Just keep it away from protruding objects in your bag and I'm sure you'll be fine.
