Banggood

It seemed easy to use, so I added order. Although it was displayed from the same power supply, there is a delicate error. There is no problem in practical use.

looks fine to me

Accuracy is reasonable

A+++

👍👌

Interesting voltmeter I use on my RV. The display is small, only 7mm (1/4 inch) tall. They are too bright at night, and too dim during the day for driving, so don't put on your dash, unless it's hard to see from the drivers seat. I placed it low near the passengers seat, well away from the drivers view. There are 3 connections, Main, Aux and Ground. They are not marked, The "+" is Main, the "-" (brass colored connection) is Ground, and the middle is the Aux input. The "Main" is where it gets it's

Very small and compact little unit . Ideal for RV and camper use to keep an eye on your battery voltages. Fast shipping -

using to measure solar panel and controller output on camper van. works ok. note negative is common to both displays.

it's a little smaller than i was thinking but it works really well and the voltage is spot on. I would recommend this to others

super product
