DESC: It happens to the best of us...you're running out of battery and far from a charging source. Just grab the slender, disposable charger, plug in, and keep talking. The phone will begin charging immediately. Use multiple times, up to one hour. Available for Nokia (all models made from 2000 on); Motorola (most current models) and Sony Ericsson (most models). Not sure if the Cellboost fits your phone? Take a look at our expanded application guide .
