  1. We purchased the EMS-PT30X about 11 months ago and used it for 6 or 7 trips. This surge protector displays amps being consumed so you know if limits are being surpassed. A little bulking, but manageable and while it’s made for outdoor use, I tend to keep a plastic bag over the plugged in unit to ensure it’s lomg use. I use a couple of pad locks and a chain with one lonck around the cord and the other end locked to the eclectical outlet. The delay of electric flow after plugging in or an electrical interruption ensures RV components are protected. Have only used it for a couple of months and so far so good
