Battery Boy
This article is about batteries that you can use to provide backup power for your laptop. The emphasis is on the two external batteries that I haved actually used: the Tekkeon myPower ALL MP 3450 and the Duracell/Xantrex XPower Powersource Mobile 100.
The bottom line? I bought one of each. The Tekkeon was better designed for the specific purpose of use with a laptop, as I’ll explain below. The Xantrex, however, was a battery that could more conveniently be used as a power supply for a variety of devices.
