It is now April 30, and I've had this for about 6 months now. It's still going very strong, and I'm very happy with my purchase. I travel A LOT, and it's been extremely reliable and durable.

I've noticed a lot of 1-star reviews of people saying that their battery just completely died. That's because they discharged the battery down to 0%. 0% in a lithium battery means complete death of the battery. That is why nearly all smartphones and such report 0% battery left, when in actuality, there's 20% charge left. This is so that the battery won't die.

You MUST keep in mind, that any lithium battery pack, regardless of how new it is, will DIE if you discharge it completely. Usually, devices have software that forces the device to shutdown if it gets too low. A device's battery meter that shows a 0% charge, actually means it has around 20% charge left. This is a reserve, because once that battery reaches 0%, it's dead.

Everyone has to keep this mind when using ANY battery out there. Keep it plugged in every now and then when you're not traveling. There should be enough reserve for a few days if you discharge the battery down to the LED's 0%. This has so much capacity, that I rarely had it go down to 1 green LED left. Lithium batteries last much longer if you keep it at a moderate charge while it's being stored. None of my laptop batteries last less than 5 years, because I always keep them charged (people usually change them out between 2-5 years).


I bought this recently, and it's the best external battery pack you can buy. I went through several days of researching reviews and specs of high-capacity batteries all over. Hands down, this is the BEST ONE. Buy it. Now.

Size: 13000mAhColor: Black
Very nice built and nice weight for the amount of power it provides. The 3 things I would have changed with this unit..

1. Include a better quality LED light, it was a nice idea but the execution of that part was not great. It just doesnt provide very much light, not looking for cree LED but something brighter would have been nicer and very possible without using more power.

2. A higher quality cable would have also been nice, the included cable just feels like a cheap cable you get from a ebay china seller that sell for a dollar.

3. Include a 2amp charger to charge the battery pack itself, i'm lucky to have lots of 2amp chargers around but I know most people have only the ones included with their phones which are usually .5 or 1 amp. If it's taking too long to charge make sure you have a high quality 2amp charger.

I got one of these (the 18,000 mAh version) through a Kickstarter campaign (just ended 5/31/13) and was kind of surprised to see it on Amazon so quickly. So far, I really like this. I've charged my Kindle Paperwhite 3G, 6" High Resolution Display with Built-in Light, Free 3G + Wi-Fi - Includes Special Offers, my Samsung Galaxy Tab 2 (7-Inch, Wi-Fi), and my Samsung Galaxy S III/S3 GT-I9300 Factory Unlocked Phone - International Version (Pebble Blue) all on the same initial charge. The phone and Kindle still had about 1/2 charge left when I started, but the tablet was completely dead when I plugged it in and all three charged to 100%. I'm not sure how much is left in the bank now (>25% according to the light) but it's enough to turn on the flashlight, which is quite bright!

This has a full rubber coating that's nice and grippy and will keep this from slipping off the table when your cat jumps up. It's slightly shorter and wider than my phone, and about twice as thick. It's able to charge 2 USB things at once, and comes with a 2-in-1 micro USB/iPhone (old style) charging cord. If you want to charge your Galaxy Tablet, you'll have to provide your own plug. (Not a problem for me - I'm just happy it will charge the Galaxy tab at all.) It's got a flashlight - click the on/off switch TWICE to turn that on or off. It's about 2.5 times as heavy as my phone (using the scientific process of holding one in each hand and guestimating).

Initially, this battery was a life saver, it charged multiple devices like a charm. With less than two months, whenever I plug any mobile device to it, it would make a hissing noise and not charge. I Had high hopes for this charger.

Size: 13000mAhColor: Black Verified Purchase
I purchased the 13000mah Limeade battery pack.
(Updates at bottom, 2013-07-04, 2013-08-01)

I was very excited to see all of the positive reviews for this. The people behind the product seemed genuinely interested in a quality product, and it seemed perfect for my multiple flights, the overnight "sleep" while connecting in LA's airport, and road trips from July 4th through the 18th.

The Limeade battery did charge itself at a great rate, as advertised. I wasn't around for it, but it was definitely quick and took what my S4 charger could offer. I liked that, a lot.

It's a great size. I was a little concerned that it might be too bulky, but I have an S4 and this pack won't bother me at all.

It arrived 25-50% charged, as lithium-ion batteries should be when sitting on a shelf, unused. Many me people complain about receiving phones or batteries at half charge or a bit less, but in actuality, that's GOOD customer service, not bad; fully-charged or discharged is not ideal. They're extending the life of the battery a bit more until it's shipped.

It's built quite well. There's no worry of a removable part sporadically falling off, it feels solid and compact, and if I drop it into my jeans' pocket to charge my phone while moving around, there aren't pointy corners to jab me.

Over a couple of 20-minute periods, the Limeade battery's 2.1amp output port briefly peaked at ~750ma (0.75amps), but consistently output just 500-600ma (0.5-0.6amps). I tried the Limeade-supplied USB cable as well as my Samsung OEM cable and results were consistent between the two.

Over another 20-minute period, the Limeade battery's 1.0amp briefly peaked at ~600ma (0.6amps), but consistently output only 350-500ma (0.35-0.5amps).
