works best in lighting and electrical engineering

We bought a cheaper one again and sent it back. This one works great. Without him I wouldn't have gone boating. Bad/empty battery = bad day at the lake.

Pros
  • new
Cons
  • boring packaging

Auxiliary battery not reading voltage

Just installed a 10/5/20 volt meter and the auxiliary battery LEDs are not reading voltage. My Fluke meter reads 12.8 volts on the main battery and 11.2 volts on the auxiliary battery, but this meter reads nothing on the auxiliary battery.

Pros
  • Permanent test results
Cons
  • I will add later

Not Outdoors: Lighting and Electrical

Both battery indicators work as they should. The displays are reassembled into the plastic base and are completely open and exposed to the elements. Don't even think about putting them on a boat between the rain and salt, they won't last a week.

Pros
  • Impressive
Cons
  • Available in Black Only

Works as described but is too bright at night and won't turn off. Dazzling

Extremely bright at night. Dazzle must have 2 lighting modes or an auto dimmer. The tension rose a little. measured against a +-2VDC precision desktop power supply. The company has to add some costs to make a quality product!

Pros
  • Best in its niche
Cons
  • Expensive

Super readable, over 95% accurate!

I tested this battery voltmeter when I received it and made a direct comparison to a high-end battery voltmeter. After numerous tests I have come to the conclusion that this MNJ voltmeter is over 95% accurate! There are practically no problems reading volts. 10/10 I will buy again for my next car project. I absolutely love how easy the screens are to read volts. I can be far away from the voltmeter and still read the volts. Not too bright for nighttime uses so the light won't bother you whenโ€ฆ

Pros
  • Dope ๐Ÿ”ฅ
Cons
  • Out of fashion

Good until it gets wet then it gets dangerously bad

Installation on my boat was easy, was very neat and looked great, perfectly level. It's hard to see in the sun but otherwise it's nice and bright. Everything worked fine until the water got on the device, like any other device installed on the boat, on the center console. Once water hit the unit the AUX side read 20+ volts on a 12 volt marine application. Other instruments on the AUX side started resetting randomly as they seemed to be receiving more voltage than their allowable range. Itโ€ฆ

Pros
  • Inspires confidence
Cons
  • Appearance

works great + next day delivery

no complaints here, reads a lithium and an AGM battery connected together with the battery relay on my honda pioneer 1000, the lithium battery is draining due to many accessories and I wanted to control usage before turning on the solar manipulator the roof installed so my accessories don't deplete the system backup

Pros
  • MNJ Round dual voltmeter, real-time monitoring of 2 car batteries, timely reminder to charge or replace, better avoid running out of battery when car engine starts!
Cons
  • Secret
