This is a nice little 1.5 x
2 x 3.5 inch precision charger which uses switchmode technology rather than
transformer technology. Switchmode makes it smaller, lighter, more efficient,
and ensures a high degree of voltage regulation no matter what the AC input
voltage is. This makes it particularly useful when the car is a long way from
the AC outlet because it compensates for AC voltage drop in the extension
cord.
