Mini Waterproof Voltmeter,2in1 LED Battery Capacity Monitor Gauge Meter DC 12V-24V Universal for Car/Motorcycle/Truck – Green

It's a well-finished product, The meter was easy to fit by installing it adjacent the 12V power outlet in the rear of car. The connector blocks for the wiring aren't the best in the business but did the trick, which is fine. I've now checked the readings, comparing with a separate voltmeter, and they're accurate. The battery efficiency reading is very useful. Much easier than hunting out the voltmeter and doing checks under the bonnet, so, very pleased.

Doesn't budge once it gets to 88% and sticks on 12.8v too. Buy a better one.

WOULD BE GOOD TO MOUNT

Does as it says - clear display unlike some cheaper ones.

Easy to fit and connect, works as advertised. Fitted to top of battery cover.

I used it in my car To keep an eye on the battery. And it was so easy to install.

Works great !! - great value item .. I’ve wired it to the ignition, it’s perfect for checking if I have enough charge before starting my boat..

These are perfect. Really well made and look really good in place.
