This little suction cup works great. I live in an RV and travel across the country. When connecting to the power supply in the motorhome, I plug this voltmeter into the socket on the rig. As soon as 50 amps are being applied to the installation, I look at this volt meter to make sure it's at or near 120 volts before turning on things like the air conditioner, refrigerator, or water heater.

This is a great little voltmeter that did a great job reporting the voltage on our motorhome. We found that our alternator was not running as smoothly and the air conditioning was difficult to turn on. After researching possible errors, we came across a suggestion to check the voltage. It turned out that the generator did not give the voltage required to turn on the AC power. After some fine-tuning, everything is now running smoothly and the sockets report 118-119 voltage. I'm glad such an…
