With our previous 'van(a Freedom), we had an internal 240v light and the radio running from the mains, so it was obvious if the mains supply failed.

With our new 'van(Eldis Xplore), we had a mains failure on our last trip, and the only reason that we discovered the problem was that we noticed the tiny LED lights on the fridge flashing.

Is there any sort of gadget that you can plug into a 240v socket that will buzz(or something) when mains power goes off?
