Lately, external battery packs have become more popular than extended batteries, which is probably due to the fact that most OEMs are doing non-removable batteries these days. We've seen a lot of high capacity battery packs out there, but I don't think I've ever seen one this big. This one is a 26,000mAh battery. Yes that's 26 thousand. Just to give you an idea of exactly how big that is, it's almost 9 times the size of the battery in the G2, and about 11 times the size of the battery in the Moto X.
This battery has over 1000 recharge cycles over it's lifetime, so it should last you a pretty long time. It's got a stylish quality design with aluminum alloy body which makes it safer and more sturdy than plastic. It also comes with 10 different connectors for smartphones, tablets and more. The battery will take about 5-6 hours to charge, which is expected, given the size of the battery inside. This is definitely a massive battery, and if you're going camping or on a road trip, this is a good item to pick up, as it will probably last you a few days.
Intocircuit also offers a 12,000mAh battery pack, which is also linked below.
