    Customer Product Reviews

    Rated 4.5 out of 5★ by 30reviewers.
    Rated 5 out of 5★ by Excellent tool Excellent display, day or night and ideal for monitoring battery and alternator charging status. I see a lot of people broken down on the highway and the worst thing is when they are with their families. As a mechanic, I often stop to help, especially when there are children involved and 8 out of 10 times, it's the vehicles charging system that has failed. This product easily allows me to check my vehicles charging system and this way, I can prevent stalling on the road, especially if I have my familly with me. Because I know what the charging system should read, I can fix the problem, before it every happens. Great tool to have. 08/30/2012
    Rated 5 out of 5★ by GREAT DEVICE OF CHECKING THE BATTERY 12/20/2012
    Rated 3 out of 5★ by Only tried it once. Need to compare it against another device for accuracy. So far I like it. 06/22/2013
    Rated 5 out of 5★ by Super Value and Accurate Bought for its two decimal readout and adjustable head. When I checked its accuracy against a $150 Fluke DIgital Multimeter, the Equus voltage was within 0.02 volts. Wow!Exceeded my expectations, and at $13 it is a great value. Every RV or Boat should have one as a primary or secondary battery monitor. 03/03/2014
    Rated 5 out of 5★ by Excellent Product Easy to use, accurate readings, nice easy to read bright display with large numerals. Head tilts for easy to read angle. 03/08/2013
    Rated 5 out of 5★ by Can't go wrong Handy, reliable, very large readout. The lights may or may not apply to your type of battery, but being able to rotate the face makes this very adaptable. 03/01/2014
    Rated 5 out of 5★ by i love it its just what i needed for my rv. 07/04/2013
    Rated 5 out of 5★ by Plug-in voltmeter was "a perfect fit". I use this voltmeter to provide an inexpensive way to get a reading of my camper battery's voltage, so as not to under or overcharge it. I installed a weatherproof power socket right on the battery box, located on the trailer tongue, and hooked it up to the battery terminals with an in-line 10 amp fuse on the positive lead. Then, because the voltmeter is a plug-in type, I can easily pull it out after getting a quick reading, and protect it from the weather. Afterward I can plug it into a power socket inside my tow vehicle, so as to monitor the tow vehicle's battery as well. The meter has digital and lighted displays that are easy to read. Although just installed, it looks like a winner. 06/09/2014
