Cobra POWER 500W

Sheepdog

Worth having.

First use

The first time I used the device just to power a laptop (nothing else) the alarm went off after about 15 minutes of use. I needed to start the car to stop the alarm. I was hoping this would keep my laptop charged without having the car running at all. Not sure I'm going to keep this setup.

its is smaller and lighter than i had though it would be but it works
