Anker Astro E5 15000mAh Portable Battery Review

Review by Richard Lartey

 

I’ve been testing out the Anker Astro E5 15,000mAh portable charger and as promised in the video review above here are the key figures you need to know.

After fully charging the Anker Astro E5 here are the results I got. I charged my LG G2 using the 2A socket and managed to charge my device once from 20% to 100% and three times from 5% to 100%. My LG G2 has a 3000mAh battery and I was able to get 365% more charge into my phone. A quick bit of maths shows that the actual charge I was able to get out of the Anker after energy loss was 10,950mAh which to be honest isn’t too bad.

Assuming the usable capacity of the Anker is 10,950mAh here are the figures you can expect to get from some of the most popular smartphones:

  • Device name – Battery Capacity – Expected Results
  • Apple iPhone 5s – 1560mAh – 7 full charges
  • Apple iPhone 5c – 1510mAh – 7 full charges
  • Apple iPhone 5 – 1440mAh – 7.6 charges
  • Apple iPhone 4s – 1432mAh – 7.6 charges
  • Apple iPhone 4 – 1420mAh – 7.6 charges
  • LG G2 – 3000mAh – 3.7 charges
  • Samsung Galaxy S5 – 2800mAh – 3.9 charges
  • Samsung Galaxy S4 – 2600mAh – 4.2 charges
  • Samsung Galaxy Note 3 – 3200mAh – 3.4 charges
  • HTC One – 2300mAh – 4.8 charges
  • HTC One M8 – 2600mAh – 4.2 charges

All in all I think the Anker Astro E5 is a fantastic bit of kit which will now be taking a well deserved spot in my travel bag. You can pick up an E5 from Amazon, it’s available in both white and black.

I’m going to Glastonbury, shouldn’t I just buy the EE charger?

To put it simply no, and I’ll explain why in a second. For everyone unfamiliar with it EE are offering a 2000mAh Power Bar for Glastonbury Festival priced at £20. Once the charge has been depleted you can take the charger back to the EE tent at the festival and get it replaced for free. You can swap the charger as many times as you like and take the last one you end up with home.

On paper this sounds brilliant but don’t be fooled, you’re actually getting a pretty bad deal. For starters the charger only holds 2000mAh, once you take into account energy loss the usable capacity is around 1500mAh. That will just about charge up an iPhone once but won’t even come close to fully charging other smartphones. Looking at my LG G2 for example, it has a 3000mAh battery but the EE charger will only offer around 1500mAh so I’ll barely get the phone up to 50% charge before the charger conks out.

The capacity thing isn’t too much of a problem at the festival because of course you can take the charger back to the EE tent and get a fully charged one, it’s once you leave the festival that the EE solution really loses its value for money. Once you’re unable to replace the Power Bar with a fully charged one at will you’re left with a device that will barely charge your phone once and will be pretty much useless during any trip away from home, bear in mind you’ve paid £20 for it too.

All in all the EE Power Bar pretty bad, the ability to swap it for a fully charged one as many times as you like at Glastonbury is great, but the low capacity really lets it down, to a point where when you leave the festival it will just become an expensive paperweight. Perhaps at a lower price point closer to other chargers of the same capacity the EE Power Bar would be a more attractive option, but as it stands with the £20 price tag I’d say avoid at all costs.
