It loses power and play havoc with the Garmin.

The Product looks good and is the only one i can find to power a garmin, but used it on a one week trip to the bahamas and the the pin that provides power to the gps rusted and broke off, how can that be prevented, amazon is going to do a 1 times refund, will try it one more time.

No power port to worry

After just one (very long) trip it started acting up: intermittent "External power lost" message on GPS, pretty annoying when you have to hit "STAY ON" every few minutes, got to the point that I would leave it unplugged
