DaierTek Battery Voltage Meter Waterproof DC 12V 24V LED Voltmeter Panel 12 Volt 24 Volt 36 Volt Battery Monitor with Blue Light Round Digital Voltage Display for Marine Boat Car Automotive Motorcycle

Small and handy, reads dc voltage as it should, and will be used to monitor dc in my RV.

Works great , used it in my mud truck its been through it lol

Works great on utilities and it is a good value for the money. It’s a decent size and basic design and easy to read and bright enough to see.

Quick and simple

These work great. Bought two of them and mounted them in the battery boxes on my boat. They don't have enough of a draw to talk about. It's nice to be able to monitor battery voltage since my boat didn't come with a gauge in the dash.

Great voltage meter using it for my 81 toyota pickup wires are good not to thin and has a fuse built in which is major plus!! A must have. I'd definitely buy again and recommend if you want to keep a eye out for the voltage reading of your vehicle. The length of the 2 wires worked great for me it may or may not work for you if your intending to wire up to your battery which I wouldn't do, I simply spliced into a switched wire and grounded it to the closest body frame and worked great for me

Works good and I put it on my riding mower. I had to rebuild the wiring for my rider mower. Pesky little critter chewed the wiring all up. I like to know if my charge system is working while it's running and my battery has enough power to crank it over. Easy hookup to the start switch.

Terrible quality. The meter has .25" quick connects (QC). One cycle of disconnecting and reconnecting the wires moved the positive QC terminal enough to break it's electrical connection inside the meter so meter does not work. Meter case is ultrasonically welded so cannot be opened for repair. Bought this unit as it seemed a good value for the features but in reality is low quality JUNK. Advertised as waterproof but there is no seal where the QC pins enter the meter body, so outright false there. Why won't it let me rate zero stars? It does not deserve even 1 star.

Très bon petit voltmètre. Précis et bien lisible.

Measures voltage well, I use in my car to make sure alternator is charging the battery good in the colder weather months, much easier to monitor charging system this way in my opinion,

Very easy install and works as described.

Nice little unit. Easy install

It does what its supposed to. I’m happy with it. Good quality
