We're featuring this external battery charger for three reasons. One: it's a pretty neat piece of kit in its own right, with a huge 12000mAh capacity (4-8 charges for most recent Android phones) and four USB charging ports, three of which can be active simultaneously. Two: the manufacturer made some small but pertinent additions to the hardware design after receiving feedback from a knowledgeable customer. Three: at $40, it would be a pretty good deal even for a basic 1-port charger of this capacity. With the extra features, it's a downright bargain.

The EasyAcc charger's biggest differentiator is its four standard USB charging ports ,which are set to amperage outputs between .5A and 2.1A. That means that it supports charging for tablets on the higher ports, plus the "rapid charging" feature of some smartphones. For most hardware, the charger can simultaneously power two tablets or three phones at the same time. Adapters for MicroUSB, standard USB, MiniUSB, Samsung tablets, iDevices, and a few others are included in the box.


But what's really impressed us about this particular unit is that the manufacturer saw one of the more detailed reviews on Amazon and decided to amend the hardware to address it. After Amazon user "Aragorn" posted an exhaustive review of the charger in October, EasyAcc added amperage labels for the four USB ports (5v/0.5A, 5v/1.3A, 5v/1.0A, 5v/2.1A) and a handy bag for holding all the cables and adapters. We're happy to support any manufacturer, big or small, that takes customer feedback seriously. Aragorn's review was updated in March - unfortunately, the current Amazon product shots don't reflect the changes. The charger has a 4.6 star rating after 300 reviews.

The EasyAcc 12000mAh battery pack is a whopping .7 pounds, and uses a lithium polymer battery for more lifetime recharge cycles. The plastic body is available with either black or white panels. It's currently listed at $39.99 on Amazon, and qualifies for free 2-day shipping for Amazon Prime members - which you'll definitely want if you're heading to Google I/O next week.

      Fixed, thanks.

  • Craig Simpson

    I literally bought this about 14-6 hours ago.

    • http://www.androidpolice.com/ Artem Russakovskii

      About how many now?

      • Craig Simpson

        14-16 hours ago. Did not see that missing tenth placer. But it should be here sometime today. Will see how it fares charging my N7, and Optimus G on lte at the same time for a long car ride.

    • andy_o

      I buy my things figuratively. It's cheaper that way.

  • Mike Loomis

    OK. I just bought one. I hope the low price isn't for getting rid of the leftover stock of the older design. Still a good deal anyway, though.

    • http://www.androidpolice.com/ Artem Russakovskii

      According to the price history, it's been 40 bucks for a while now. We just didn't hear about it.

      • Craig Simpson

        It actually dropped. I added it ~24 hours ago and it dropped to 39.99 between 24-18 hours ago.

        • Dave

          OK, seriously, were you just not at school on the day when they taught how to write ranges? :D

          • Craig Simpson

            Depends on what kind of Math Classes you have taken and what purposes you would be using ranges in. We use ranges differently in class and has become a way of life. I actually used it to reference the time pool between the 24-18 from the 24 hours. Indicating a plus or minus from the 18 but with a stop of 24. Makes sense?

    I've had this for months and love it. I would keep it in my bag with and it would keep my Nexus 7 and various other gadgets charged for a week. Sometimes I feel it has too much capacity because I think it can go forever and forget to charge it!

    Ingress make this a must.

  • Lexster

    I have a Power Bag, but I bought one of these, too. Stop showing me deals, AP! You're making me spend money!

  • Robert Jakiel

    NICE! Just picked it up. This will make the weekends in the woods so much easier!

  • http://twitter.com/olkjas Noah Hamlen

    I've had one for a while, that I keep in my bag. I get rather obsessive with it though. If my Nexus 4 ever drops below like 90%, I end up plugging it in! It really is a nice battery.

  • Stephen Fronda


    I found this one for cheaper: $24.78 ... It's only got 2 ports though.

  • David S

    Just an FYI, I bought this exact item and it arrived the day I was leaving on a trip. I could tell the brick was charging and the little lights would come on, but I couldn't get it to charge any of three phones we had with us. So, yes, great deal, great accessory, but if you need it to work the day you get it, I don't know that I would go with this brand.

      All rechargeable batteries leave factory with 20% or lower charge, because the battery at 100% charge degrades much quicker, when unused. Any battery needs to be fully charged after unboxing to maximize it's capacity, the ones that allow you to use them before that just don't have smart electronics preventing such usage.
      Power freaks usually perform 4 full recharge-discharge cycles on any new piece of electronics, to fully pump up battery.

  • WinDroidGuy

    You can get the 12000mAh and 8600mAh chargers for $61, that seems like a better bargain...add them both to your cart and you'll see the instant discount :)

  • http://twitter.com/matxor MatXOR

    Can Canadians partake on this awesome deal? It seems the one on the Canadian site is $172.

  • Matthew Fry

    Does it come with a head strap so I can charge my Google Glass while I wear it?

  • http://www.arcane.org Mystech

    If I'm reading this correctly it still won't charge the Asus Transformer Infinity, will it? :-(

  • Steven S

    I'll just wait for the 18,000mAh Limeade Blast that I'm backing on Kickstarter :-)

    2.1A and 1A output ports, and industry-first 2.1A input port
