Compact Power Systems has expanded its Cellboost line of disposable battery/chargers for cell phones with a new device for the iPod. (The company also launched new models for smart phones, camcorders, and Nintendo Game Boy Advance SP and DS systems). The compact Cellboost is capable of bringing powerless or near-powerless iPods back to life without any external electricity, battery changes or significant charging time. The Cellboost units will also allow for users to continue usage while simultaneously charging their device. It can also be used in one charging session or several, and can be thrown away when its power is exhausted. The company said the iPod unit “delivers several hours of additional playback time” and did not provide pricing.
