Progressive EMS Power Protector

Easy to set up and works as advertised. Great to know your power source is adequate and secure and not going to damage your Airstream electrical system.

Our last power monitor sacrificed itself to protect our Airstream: A valiant effort in a good cause. I replaced it with this Progressive unit, which seems to work well, and has more-informative error codes than the last unit (which shall remain nameless). So far, so good. And I'll admit I've not yet had a lick of trouble from anything from AirGear -- it's valuable to have a "curated" source!

Good product.
