How does it work?
Mugen Power is brand of extended batteries for handsets, pocket Wi-Fi, and laptops. Mugen produces two types of battery:

1. Replacement battery of same size and claimed slightly higher capacity than the original one.

2. Extended battery of larger capacity and size than original.

The Mugen Atomic Battery for Galaxy Note 2 is a new breed of extended battery which uses a groundbreaking nuclear-compound technology to increase the average smartphone battery life by up to 180 times longer.

The technology is quite scary with word "atomic" or "nuclear" technology fused inside, but all of their batteries carry the CE mark and satisfy the Restriction of Hazardous Substances (RoHS)

Alternatively, if you do not want such overwhelming power for a small battery, Mugen also offer a 6400mAh battery for Galaxy Note 2 which is a little bit larger than the device's original but serves twice as much power.

Since the battery is quite large, the modification of the back casing will make the device a little bit thicker unlike before. It costs at least $100 and works to most Galaxy Note 2 variant including the US versions from AT&T, Sprint, T-Mobile and US Cellular.

Mugen Power also supports HTC, iPhone, LG, Blackberry, and Nokia.
