Title: It keeps my battery charged up
Review: I've had this about 2 months, and it seems to work. I leave it sitting on the dash board of my car that I only rarely drive. Because the car operates a clock and a few electric devices all the time, the battery would drain down. This keeps the battery fully-charged.It has a long wire that plugs into the cigarette lighter. I leave it plugged in even when I'm driving (it has a diode to protect it from reverse current flow). Thus, it couldn't be easier to use.
