External batteries benchmarked, the portable juice is loose

A lot of portable PC power cells last for only four or five hours, after which you'll find yourself chained to a wall socket. Good thing there are external batteries to keep us in current when a plug's nowhere to be found, and Tom's Hardware has done some benchmarking on a slew of such devices so you'll know which one's suited for you. A Dell Vostro 3300 and an Inspiron Mini 10 running Windows 7 were used to put packs from Amstron, Brunton, Digipower, Electrovaya, Energizer, Lenmar, PowerTraveller and Tekkeon through some real-world paces -- we're talking word processing and web surfing, not fragging and film editing. So if you're in the market for a mobile power unit, hit the source link and get the down and dirty on which external battery's best.
