Review on RV220-50-SP 50 Amp Voltage πŸ”Œ Booster with Surge Protection by Hughes Autoformers by Lawrence Crespo

Revainrating 4 out of 5

Works as advertised, looks well put together, just needs a little tweaking to be perfect.

I bought this to solve problems I was having in a seasonal site where the voltage could drop to 94V. We have a small trailer so my average amp draw with fridge and air con was around 9 -10 amps. (Obviously a toaster oven or microwave will cause large spatters.) I replaced the AC unit with a more efficient unit and now with Autoformer my park draw is around 7-8 amps, even with voltage adjustments. Despite its 10% rating, it's like a sliding scale. If it only needs to boost 7 volts, that's all it does. When I get very low voltage on the poles it seems to be over 10%, I've seen around 13% this weekend and never went below 111v in the trailer. In order to get the final star for the price, they need to integrate the same Bluetooth capabilities they sell in Surge's specialty devices. As I wanted to keep an eye on the park I had to buy one separately and now have two combo surge protectors which is a bit of a pole mess, unnecessary and just adds to my cost. Just pay another $50 for it and turn on bluetooth on this device.

Pros
  • Inverter
Cons
  • Expensive
