Customer Reviews:

  • outstanding voltmeter
    I bought two of these to monitor the battery system in my motorhome and another to monitor the batteries in my house that I run my computers off of. I can tell at a glance the state of my batteries.

    Wish I had bought this a long time ago as it would have prevented both overcharging and undercharging by giving me an active monitor of the battery voltage.

    Highly recommend....more info
  • Simple and useful ~
    This device gives a constant, backlit readout of battery voltage, together with color-coded info lights to help the inexperienced figure out whether those readings are good or bad. Sturdy, well-designed, and useful for basic battery and charging-system checking/monitoring. ...more info
  • Great Option for Vehicles Without a Volt or Amp Meter
    I recently had electrical issues with my vehicle and was unable to monitor the charging system and ended up with a dead battery a couple times. I'm pleased with the Equus Charging Monitor as it gives me a digital readout of whats going on with my electrical and charging system on the Vehicle. If my lights dim I don't have to guess what is happening all I have to do is check the Equus and I know if my charging system is working correctly. I would recommend this product to anyone that only has a idiot light on there dash. ...more info

    I have purchased two of these monitors. I bought the first one to monitor the battery on my van. I was so impressed with it that I bought a second one to monitor my Jump N Carry 660 jump start battery. Great tool!...more info
  • Great 4 Family Outings!
    Our family love going to the Drive In Movies but we were always concerned about would we have trouble getting home due to the fact that our truck was running its radio the entire time so that we could hear the movie. This device helped a lot. We knew when we needed to start the truck so the battery wouldn't go dead. YAY!...more info
  • The Equus Voltage Monitor
    I bought the voltage monitor and it works very well. I want to say that
    the screen protective laminate, now has a small tab, and it is very easy
    to remove. This comment is made to previous complaints regarding the
    protective laminate removal. I would recommend this item, if you want to monitor your battery charge and/or if you have a power pack....more info
