Review on 🔌 POWSAF 30-Amp RV Extension Cord, 25-FT Waterproof RV Surge Protector (4100 Joules) with Circuit Analyzer LED Indicator Light, Designed with Easy-to-Use Handles, RV Accessory by David Butterfield

I like this surge protector for my trailer because of its length. I can also use it at home to plug into a 30 amp outlet in the garage to power up the trailer before driving. A surge protector is a must when using a generator or plugging it into a camping outlet - it will save you a lot of money in the long run by protecting your caravan/motorhome from power surges or your generator. Power surges can damage trailer wiring or the main power supply. This POWSAF surge protector does the job perfectly! Easy to read green indicators on the head let you know the performance is at the right level for your trailer. Peace of mind is priceless!
