Review: Anker Astro E4 13000mAh External Battery Charger Power Bank


Well what can I say, this is truly a monster. If you are going away on a trip for a few days (or are packing a bag for a day trip) this is an essential device to take.

In the box you get the battery bank, cable and attachments for a micro USB, Mini USB and also for an iPod. The battery is suitably heavy and this should be expected for something of its capacity. Don’t buy this expecting something you can carry in a pocket to give you a bit of a boost if you may need it. It’s too big for just carrying around ‘in case’. This is for when you KNOW you’ll need to recharge your device(s)!


I won’t go into too much detail as it’s a pretty standard battery bank. No bells and whistles, but what I will say is this will charge a device many times over and the ability to charge 2 at once is a great feature. I often travel with work to other countries, and this will be a god-send for when I’m using my phone to watch video’s or listen to music while flying and need to recharge. I will now easily be able to carry this in my flight bag and recharge my HTC One at least 4 to 5 times over!

This is a great quality product from a great company. I can’t praise Anker highly enough for all products I have from them, the build is exceptional and the practicality offered is unsurpassable.


If like me you travel lots then this is a must have to keep in your travel bag…. just note that it will take several hours to re-charge. From a full discharge it will take 8/9 hours to fully recharge if using an AC adapter, this will obviously be longer if charging via a USB port on a computer!

  1. Some of my friends are using RAVPower KinghtRider 14000mAh. The performance is pretty good. I’m thinking about buy one. But how’s this Anker Astro compared with the RAVPower KnightRider?

    • I’m afraid I haven’t had that battery charger to be able to compare. All I will say though is that Anker are widely reputed to produce good quality battery chargers, the E4 is getting great reviews all over the net.
