🚗 DC 12V Car Voltmeter Gauge with LED Display - Waterproof, Durable and Versatile for Vehicles, Boats, Motorcycles and More Review

I bought 2 and one of the readings is upside down. Good quality control. Then he asked me to send it back to replace it? It costs more than it's worth sending back! I would suggest finding another provider that is easier to deal with, offers better quality control, or basic customer service.

Excellent gauge. The meter held a solid number and didn't change until the voltage changed, unlike other meters I've installed that kept switching back in numbers even when there were no voltage fluctuations. I checked my $500 meter and it was accurate to hundredths of a volt.

I bought this to fit on my RV's battery box. The battery was recently charged and showed 12.58 volts on my multimeter. The reading on this meter fluctuated between 12.3 and 12.5 volts with no load. I thought I had a faulty meter so I ordered a replacement that does the same thing. Had to return due to read error.

This little scale is bright! I hooked it up to a 9 volt battery with test leads to see if it worked. The brightness was amazing! She is small. Little more than an American quarter of a coin, or a Coca-Cola bottle cap for non-Americans. So far it seems to be reading exactly 9.42 on a 9 volt battery, which is about right. Good little cheap voltmeter for the money.

The plugs supplied are a little cheap and one came loose from the cord but I had spares so no big deal. I installed it in my RV to more precisely control battery voltage and it works great. It's bright enough for reading but not too bright, illuminating the entire camper at night. Super easy installation. I just used a Christmas tree drill bit to drill the hole. Need about 1 7/8 holes for it to sit flush

I use this Linkstyle car voltmeter DC 12v 24v to monitor the charge on my trolling motor. I built it right into the battery compartment so I always have it in front of me. Since it's waterproof, I got this one. I ruined a couple of multimeters using them on the boat so even if this one gets damaged I'll lose nothing but a few bucks. It serves its purpose and matches the voltage of my multimeter.
