With its portable 50 Amp surge guard, Technology Research has earned its third and final spot on our list. The guard can keep electronics safe from surges clocking in at up to 3,850 joules, ensuring your valuable equipment stays safe.

It continuously monitors the voltage and Amperage being drawn by the RV it’s plugged into, displaying the readout on an easily visible LCD screen. As well as Volts and Amps, the screen also offers an insight into any electrical problems that emerge from the power supply. Any miswiring, surge, or low voltage situation is immediately picked up on, and the power supply is automatically halted. Customers say the unit is a sound investment that can stand up to drizzly weather, and reliably keeps RV electronics safe.
