Eversame Flat US Plug AC 80-300V LCD Digital Voltmeter Voltage Measuring Monitor, AC 110V 220V Voltage Panel Power Line Volt Test Monitor Gauge Meter for Household Plug into Outlet to Measure Voltage

I live and work in a dry, hot, dusty West African country where the local electrical utility maintains a nominal line voltage of 80 to 325 volts. volts. Automatic voltage regulators (AVRs) and surge suppressors protect all of my electrical and electronic equipment. Lights-outages are a result of the wild and prolonged powerline disruptions. The AVRs growl like angry kittens when exposed to incandescent, fluorescent, and LED lighting. This voltmeter is plugged into an unprotected multioutlet next to my desk, before my AVRs and surge suppressors, to provide me with an instantaneous voltage reading as soon as the AVRs begin to regulate the voltage. Knowing what you're up against is extremely beneficial. I plug the LED voltmeter into a regulated surge suppressor every now and then to make sure that my powerline conditioning efforts are working. I may purchase a second to keep on the downstream side, as the LED voltmeter has worked flawlessly for the past four months.

This was purchased for use in my Class C RV. After I brought my RV in for an inspection, the RV technician recommended it to me because I had lost electrical power in my RV on a recent trip. I thought I'd blown a fuse, but there was a "burning smell" before the power went out completely. Mr. Keith recommended I use a surge protector with low voltage protection at the campsite electrical hookup post so I could visually monitor it from inside the RV and recommend I shut the a/c off if it drops below 108 and then turn off the power at the breaker. It's a small price to pay to avoid another costly repair. So far, I'm pleased.

Today I got this. It read 119 when I plugged it in. A pro voltage meter revealed a reading of 123 on the outlet. We had a major power surge after two lightning strikes, and the utility company regulator had to be replaced, which we already knew was correct. We decided to buy plug in to allow continuous visual readings after a stressful weekend of cutting power to prevent repeated surge damages. We also bought the Hughes plug-in, which gave us the same reading as our professional meter. When you go for a lower price, you may not always get what you pay for.

This volt meter is ideal for inspecting your electric service; I tested it against a professional digital volt meter and found it to be extremely accurate. The volts were exactly where they should have been. When using the air conditioner or refrigerator in an RV, it is extremely important to know the exact voltage. If the voltage is too low in an RV park, it can cause havoc with the electrical systems.

This was purchased to connect to a surge suppressor that was connecting a number of critical electronics. It's a good thing that the unit is smaller than it appears in photos. It appears to be a fat box in the photos, but it is actually a little thinner and has rounded edges. The screen is a medium-sized, light-colored display. It's blue and easy to read in general. I have no idea how accurate it is, but it appears to work. In addition, rather than updating every 30 seconds or so, the readout appears to update on the fly.

Depending on the load that is plugged into it, the voltage at a few RV parks may fluctuate. This digital voltmeter is one of my favorites because it allows me to keep track of my coach's AC voltage. The 220 is split, so I can switch it between two plugs (one on each leg) and see the voltage at a glance. It's simple to do. I checked the accuracy of this meter with a calibrated hand-held VM, and it's spot on.

Install a motorhome in the bathroom to keep an eye on voltage fluctuations. It works well and can also be used as a nightlight. Wish we'd known about this before spending the night in a park with brownouts that melted our expensive surge protector! It was well worth the small investment!.

I'm very pleased with it after several weeks of use in various campgrounds (with a variety of electricity sources). There is one caveat, however: "Accuracy" is where I put my rating. I have to assume that the accuracy is good based on the performance of my electronic equipment. Only another meter, which I, of course, do not have, could accurately determine the degree of accuracy.
