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, ivory 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.

3.0 out of 5 stars Not for outdoors 15 May 2013
By snedger
Colour Name:White
What a lovely looker!
And not as heavy or bulky as I would have supposed a 13A battery to be.
Took it out on a 37 mile walk last weekend. Needed to have my phone recording a GPS route, running all day.
First problem, as I had expected, was that the soft touch switch had been pressed in transit and so the torch was on.
Then when my phone down to 35% I started to charge it. An hour later went to check my phone and the lead had become disconnected and even worse the micro USB connector was bent. Took a chance bending it back. Managed to get phone charged up again and to record the whole route.
This would be a fabulous device to use on a long train/plane journey, but for outdoors, needs a more positive sliding switch and needs a better quality cable system - I shall be buying a dedicated USB-microUSB cable.

5.0 out of 5 stars More Power To Your Gadgets 15 May 2013
By Doc Pic
Colour Name:White
First of all, I have noticed that many of the 1 star reviews here relate to lower powered chargers. Please note that I'm reviewing the 13000mAh Astro E4 as listed.

There are lots of portable chargers on the market making choice difficult. Many of them are handy in the respect that they'll charge up your phone once or twice but that's it. These days, not only are more & more of us buying power hungry smartphones but we are also adding to the number of gadgets we own such as hands free kits, sat navs, IPods & tablet computers.

We therefore need a reliable, powerful & functional source of power. The Astro E4 does that job very well indeed. This 13000mAh power pack was provided to me by Anker in exchange for my honest feedback. I have tested it thoroughly over a number of days charging a number of different gadgets including my Samsung Galaxy Note, an iPod & even the batteries for my electronic cigarette!

Apart from assessing that the E4 worked OK, I wanted to see how many charges it would deliver. This model has two USB connections (one 2amp & the other a 1amp) which means that you can charge a pair of gadgets at the same time. That also means I have an extra USB port when connected to my computer. All very useful. In operation, the E4 charged my Galaxy Note from scratch around 6 times which included sometimes having another item on charge at the same time.

The E4 was delivered very quickly & arrived already charged which was handy. My first impression was that it was nice to look at, solidly built, quite small & light, weighing in at only 300g. Also included were 3 different connectors that will satisfy most needs & a carrying pouch which could be a little larger to accommodate the lead & connectors better.

5.0 out of 5 stars Amazing Battery Life! 13 May 2013
Colour Name:White
So far I have used this a few times when I knew I'd be gone all day and was worried I would run out of juice on one of my devices and it has come in handy too when I completely forgot to charge my phone (or other device) and I was able to get power immediately with this! I keep my Astro E4 charged and ready to go so I am always ready to go! It is amazing how helpful it has become and dependent I have become of it. Now it is a little on the heavy side but it is small enough that it fits just fine in my purse. My husband now wants one too after realizing how nice it is while he is going to all his different meetings on the go, instead of constantly looking for an outlet to charge his phone into. I cannot tell you how many social media events I go to too where everyone is huddled over a surge protector all charging their devices. This way I can charge up my phone or tablet right where I am and not worry about finding an outlet. The Astro E4 is perfect for anyone who is on-the -go and needs to be able to charge something. While yes there are usually outlets or even car chargers out there, those are not always an option or available, this is the perfect substitute! It even comes with a small little pouch to hold the battery and tips in!

I want to add too that while this portable battery does charge Apple devices, it is not just for Apple products but rather any product that fits one of the tips provided. I did though plug this into my dead iPod Touch and it restored it to full life and the Astro E4 still had 4 bars of battery life! Amazing! I have a feeling I am going to be popular when I am out with others whose devices run out of juice since I can charge both theirs and my device at the same time and still have life left in my Astro for another charge!

The battery pack I received was the white one. The general quality of the battery pack was extremely good. Felt solid and not flimsy, has a classy gloss surface which makes it look very expensive. It came with a USB cable that allows connectivity to either a micro USB connector or a connector for Apple products (both these connectors are in the package). However there was no wall charger in the package. I used my Samsung charger (5V - 1A)to charge the battery pack when it first came. It arrived half charged. You can tell by pressing a button on the battery pack and 4 blue lights will light up. Only 2 were lit when mine arrived. It took about 6 hours, with my wall charger, to fully charge a half full battery. Another reviewer here has a very detailed description of the charging times if you used more powerful chargers and all that ... please read his review for details. Mine is based on my own experience.

Charging a Samsung S 4G phone battery with the battery pack took as long as my phone's wall charger (estimated about an hour). I did not time it exactly how long it took but I was happy that it did not take longer than normal. The battery pack has 2 charging ports which has different output - 1A and 2A. According to the manual the 2A output is meant for tablets and the 1A for phones.

I think this battery pack should be a must-have for frequent travellers. As long as you can't find a wall outlet to charge your device (phone, tablet, mp3 player, handheld game console, etc) this portable battery pack will save the day. I have been purchasing Anker products for some time and so far have not been disappointed. They stand by their products and all the batteries and chargers that I have bought from them have been made to very high quality standards. I highly recommend this portable battery charger from Anker.
