The battery in the Jambox is an 11.1V 2600mAh Li-ion. Its wall charger output is 14.5V 2.48A. USB specifications will only allow 5.0 volts to had from that port, and very few laptops out there, aside from the high $ business class lappys, will allow for more than 1A to be had. Charging from a laptop will only charge the Jambox half way at best.
