I'm going away for 4 days this weekend camping. I've brought an electric coolbox which runs off of 12v or mains, unfortunately the campsite doesn't have electric hookups, so I'm going to have to resort to using the cars battery.
Question is, is this going to be a big no no and knacker the battery very quickly with the car off? Is there any kind of auto cut off that cuts the 12v socket out when the battery level is getting low, or is there a unit I can buy to do this?
Cheers all, And
