    The Astro is a rechargeable 13,000mAh battery unit that can then be used to charge a slave device connected to it via USB. Included in the package is the Power Bank, micro USB cable, user manual, and travel pouch.

    Because this is billed as MFI certified, it ships with a lightning cable for recent iOS devices which is a nice addition. This is black to match the Astro and well constructed - it certainly compares to the official cable and has no issues with charging or syncing.

    The Astro measures in at 15 x 6.2 x 2.3 cm and 295g. It feels sturdy in the hand, in part due to the weight of the internal battery and also thanks to the good construction on offer. The unit does have a smooth all over finish though so be wary of placing this somewhere it may slide.

    It features four LEDs on the top to indicate remaining power and a power button on one side to enable the remaining power indicator or to operate the LED torch function which is a handy feature that is creeping into more and more power banks. On the end it has two full sized USB ports as well as a central micro USB port for recharging which sits just above the LED torch. It takes around 6.5 hours to fully recharge the unit from empty using a 2A charger. There is no supplied charger but the included cable or indeed any other micro USB cable can be used in connection with any USB source.

    From a full charge, 13,000 mAh of portable power is on offer. To put this in an IOS perspective, an iPhone 6 rated @ 1,810 mAh could be fully charged around 7 times. An iPad mini @ 4,490 mAh could be charged almost three times while a full sized iPad Air 2 @ 7,340 mAh could be charged 1.7 times. The USB ports are not labelled with their output but utilise Anker's PowerIQ Technology to detect the connected device and charge up to maximum of 3A. Two devices can also be charged simultaneously for a combined output of 3A which makes this a flexible performer. One thing I did note during my testing was that regardless of what device you are charging or even if you are recharging the Astro, it remained cool at all times with no sign of heating up. This is a welcome surprise when it comes to portable devices and batteries.

    For me, travelling with my usual compliment of gadgets makes a product like a power bank a sensible purchase. All my portable gadgets from phones, tablets, music player, ebook reader, keyboard and camera can be charged via USB and having the ability to do this when away from a fixed power source gives real peace of mind. The Anker Astro E4 delivers a high power capacity and flexibility of dual charging in a portable and well priced package. If you are in a similar position then this comes highly recommended.

    Disclaimer. Many thanks to Anker for supplying this unit for review. As always my reviews are objective and only of my own opinion and are in no way influenced by the supplying company.

    I LOVE the way you edit your review! I'm so sick of watching people struggle and fumble to unpackaged and unwrap, so it's so refreshing to see that you 2x'd the actual parts nobody cares about. Thanks for a refreshing take on an unboxing.

    I'm curious about this power bank. It's the smallest "13,000" I've ever seen. I'm curious to the ongoing realistic expectations I would have for this big claim of capacity. The physics just don't seem to support the 13,000 mah claim.

    Let me know what you think after using it for a bit.....

    Thanks again for the best unboxing I've seen in a while!

    Thanks for your kind words. I know a lot of people enjoy the unboxing part as it gives a good idea of what exactly is in the box and how it is packaged - in my experience, better packaging usually is an indicator of a better product. That is why I leave it in there but fast forward through it - I'm just waiting on Apple to give us 4x in iOS iMovie as I do all my editing on the iPad. :)

    I have a couple of power banks around the 10,000mAh capacity from different manufacturers and they weigh in at about 230g so this one at 295g may well be spot on - I think mass is probably the best indicator. I have managed a full charge of an Air 2 and an iPhone 5s out of this as well as topping up a retina mini with capacity to spare so I don't have any concerns over the total capacity but I will try and run through an exhaustive test when I get the time for confirmation.

    Great review! I have this same one. (Actually I have the 16000) I bought it in Nov when it went on deep discount on Amazon. I love this one for flights cuz it can chage my ipad & my phone on long hauls.

    For the ladies that like to carry wristlets...this will only fit in a much larger wristlet or mini purse. Also, it's quite heavy! I know DUH! But if you have it in a mini purse and need to lay down the boom you've got some weight in your bag. ;)

    So it's for that reason that I only carry it daily in my larger bag/purse or a briefcase.

    But in my wristlet that doubles as my wallet I carry the Anker 3200 mAh 'lipstick' battery with a 3 inch lightening cable. That's perfect when you need to roll light like when you are standing in a long lines to vote.

    Both Anker products are top notch. I say get both! Get the 13000 or 16000 behemoth and get the 3200 smaller one. That way you are covered.

    I ordered this once I saw this review. It was reasonably priced and as my bag is a decent size anyway, carrying it won't be an issue. It's due for delivery tomorrow thanks to Amazon prime

    I keep buying more and more of these, be it online or when I travel.

    I now have about 15 power banks ranging from 1600mah to 17000mah... and it's so funny the ONE I keep going back to is my Mophie Powerstation Plus with the built in lightning cable. It only recharges one or two times .... but its just so easy not having to dig for a lightning cable.

    I travel internationally a week out of the year, and it just is such a pain to carry these bigger battery packs, even though they're not that big. I think I have an illness to keep buying more and more.

    I'm looking at the E3 and the Anker 2nd Gen Astro3 12800mAh. There's a significant price difference. What makes the Anker 2nd Gen Astro3 12800mAh better than the E4?

    I received mine yesterday. It's not too big and the weight is reasonable considering the amount of charging capacity it provides. I fully charged it and it'll get its maiden voyage tomorrow when I'm in work.

    Good to hear. Let us know how you get on with it.

    ----------

    It's more expensive because the 3 has three USB ports instead of two and has a higher total output of 4A.

    How about the Astro finish compared to the E3? I would prefer a rubberized type finish.

    I haven't tried the E3 so can't comment on the finish unfortunately. If I get a hold of one then I'll feedback.
