I have tried searching but I can't think of another way to ask and I haven't gotten the answer I was looking for. I read through the manual today and it seems that it doesn't stay on. That being said today at the grocery I plugged my GPS in back there and it was still being powered by the outlet roughly 30 minutes later. I want to sort this out before I put my ARB fridge back there and then have the power cut out on me and have to deal with that mess. Thanks in advance.
