Review on 💡 Highly Efficient Surge Protector: Progressive Industries EMSHW50C by Andargie Waiker

During our second trip, we had intermittent undervoltage first on L1 and then on L2 due to incorrect camping wiring. While we were not happy with the temporary failure of an air conditioner, we were very pleased to learn that EMS protected the air conditioner compressor from low voltage damage. I would add a second one. While you can install both indoor and basement displays, only one can be active at a time. So if we have a power problem and I forgot to flip the switch to change the display to internal, I still go outside in the rain. There's no way there's $90 electronics stuffed into the second display and switch assembly, so we're making it a little more user-friendly.
