🔋 MNJ Motor Digital Voltage Multimeter - DC 6.5-100V 0-100A Volt Watt Power Energy Meter Ammeter Voltmeter - LCD Digital Display with Shunt 100A 75mV Review

I have used this on my boat and truck. Both apps worked great and the screen backlight is very helpful. I would recommend this product to my friends.

Works great. My only complaint would be the tiny recessed backlit button. You can't turn it on or off with your finger. You will need a paper clip or the edge of a screwdriver or pen etc. Everything else is fine!

Works well if it could read reverse current. If you charge through the shunt, the current becomes 0, not as my charge controllers show. Alarm no audible alarm.

Bought 2 of these together. 1. worked, 2. not. 1. Works as it should, does what it should. The 2nd does nothing, so 50/50 in my experience. For some reason it is impossible to contact the seller. I would give 5 stars based on the 1st but the 2nd doesn't work. It fails 50 percent

I followed the instructions and connected according to the wiring diagram that comes with the unit. The meter turned on, but read or showed no current through the resistive load element that came with the meter. It did not work! Unfortunately, I only got past the return window on the first attempt to use it.

Inexpensive, works exactly as advertised. I connected it according to the scheme and everything worked without problems. I use it to monitor battery charge and usage/discharge stats and it does the job perfectly. I would say it was 99% accurate (good for surveillance), pretty easy to use and read. The only downside is that the shunt is 100A larger than the block.
