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.
