Thanko - Ultimate eco portable battery that gets imperceptibly charged
Thanko just released the portable battery "nPower PEG" developed by Tremont Electric (Cleveland OH, USA). A cool feature of this product is that it can get charged automatically as long as you are moving.
"nPower PEG" is charged by shaking up and down. So, you can put it in or hang it on your daily bag and spend a regular day by commuting or walking or running, and power will be generated and saved in the 2000mAh portable battery.
As a regular portable battery, it can be charged from a PC's USB port.
