The Progressive EMS-PT30X is a portable 30 amp, 120 volt, 3,600 watt unit that absorbs surges up to 1,790 joules and includes an electrical management system. It guards against over and under voltage, open ground and neutral, reverse polarity, a miswired pedestal, accidental 240 volts, surge failure and frequency problems.

Its joule number is far lower than the budget models, yet it names the longest fault-detection list here. It has an all weather shield, thermal protection, a Lexan housing and a display for low light, and it is made in the USA.

It suits full-time and frequent RVers who want faults caught before the rig is connected. The unit is a known brand with an established track record.
