Display is powered only from main terminal
Works as expected. This display is powered only from the main terminal, so digits will be blank if main voltage is zero even when positive voltage is on the aux terminal. This feature is useful in an RV application with switched start battery on main, and always hot house battery on aux. Thus house battery current drain is negligible when ignition is off.

Simple but effective
Simple connections lets me monitor my main battery and auxiliary batteries in the same location and not have two separate voltmeters

Both voltages need to be present
Must have both voltages present to work correctly

Great value
Works great duel voltage for bass boat main power and trolling motor voltage

The Mictuning double voltmeter is perfect for what I need
I picked this up as part of my plans to redesign my layout in my camper shell. I have a dual battery system with a read out in the cab, but as most of the time in camp is spent at the back of the truck I wanted a way to monitor the batteries. The Mictuning double voltmeter is perfect for what I need. As you can see in the pictures I plugged it into a power supply at work that we use for testing and the read out is bright and easy to read. The set up is also simple. There are 3 terminals on the back, 2 silver 1 gold. Unlike most applications, the Gold terminal is the ground, and that is shared between your two batteries or power sources. The 2 silver terminals are for the positive lead from each battery or power source. I tested plugging in both positive terminals together, and separately and compared them to my Fluke 400a meter and found the mictuning to be very accurate. Fluke 400A AC/DC, 600V AC/DC TRMS Clamp Meter with Frequency, Temp, & Capacitance Measurements with a NIST-Traceable Calibration Certificate with Data This appears to be fully sealed except for a small opening on the back so it should do great in the bed of the truck where there is a possibility of being exposed to the elements.

Lasted 2 years...
Works good for my dual battery setup to ensure both batteries are at charging voltage. Lasted about 2 years before the led displays started glitching, took it apart and there was lots of corrosion on contacts on led board which could have been the culprit but I already ordered another one (different brand name, but same exact clone, just labeled with different name).. Low quality but great for the price and I couldn't find anything else in this form factor.

Love it
Nice in the boat have 36 volt system in bow for trolling motor and 12 volt in transom for main motor and accessories nice to be able to see what voltage everything is at at a glance

Alles gut
Ja, es ist richtig, wie andere schreiben, dass zwischen den Anzeigen eine Toleranz/Abweichung von +- 0.1 V festzustellen ist. Das halte ich aber für absolut vertretbar bei der kleinen, praktischen Bauform. Schließlich habe ich kein Fluke-Messgerät erworben ... Einbau war problemlos, die Anzeige ist schon etwas hell, hätte mit einem geschwärztem Glas davor sicher schöner ausgesehen. Aber bei dem Preis bin ich rundherum zufrieden.

Nice dual voltage guage
Used for a modified Power Wheels project. Had a 12v circuit and a 20v circuit to be monitored and works like a charm. Flush mounted easily with step drill bit through plastic.

Cumple las espectativas.
Estoy contento, se ve muy bien, y funciona correctamente. Espero que dure... PD: durante el dia se ve muy bien, por la noche ilumina demasiado, puede llegar a ser molesto. Mejor ponerlo en un lugar que no te de a la cara directamente. Estaria muy bien poder regular la intensidad de la luz.

釣り船に装着しました。
日本語コメントが無くて不安でしたが購入して良かったです。私の使い方は24vバッテリーのディーゼルの釣り船への装着です。ソーラー充電を繋げたバッテリーは「セル用」と「その他アクセサリー用」の2つがあり今まではアナログ電圧計で計ってましたが小数点第一位目盛りまでは把握出来ません。そこでこの商品を見つけて専用スイッチも装着しました。デジタル表示は最高です。ソーラー充電でどれくらい増えていくかも日々のチェックが楽しみです。

Passt und funktioniert
Mich haben zunächst die schlechten Bewertungen fast abgeschreckt. Primär wird ja immer die Messabweichung von bis zu 0,3V angesprochen. Auch bei Amazon.com. Ich hatte aber an meinem Verwendungsort nur minimal Platz und habe im Netz keine Alternative gefunden. Also hab ich das hier bestellt. Es ist absolut wertig und ist optisch ansprechend. Einbau und Inbetriebnahme ohne Probleme. Nun zur Abweichung. Bei der Main-Anzeige habe ich keine Abweichung zu meinem Multimeter. Bei der Aux-Anzeige habe ich -0,1V. Das ist aber für mich absolut im Rahmen der Messtoleranz. Sprich, mein Exemplar ist top für meine Anwendung. Ich könnte meckern, dass mich die Prime-Lieferung 7€ mehr gekostet hat, als die Lieferung aus China. Aber gut, war meine Entscheidung, nicht zu warten. Hinweis: Aus der Spannung des Main-Eingangs zieht sich das Teil seine Betriebsspannung. Sprich, nur die Aux zu messen, ohne Main, ist nicht möglich. Main ohne Aux schon.
