 Great Option for Vehicles Without a Volt or Amp Meter November 17, 2008
Oscar Ennis (USA)
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.
 Great 4 Family Outings! November 8, 2008
Conita Clayton (Killeen, TX)
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!
outstanding voltmeter November 4, 2008
Michelle M. Ress (Felton, CA., USA)
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.
Acqurate Info November 2, 2008

Allows me to check battery condition and charge rate in my boat. Good piece of mind as I really don't want to try to start my motor with the rope pull!

I LOVE this thing. It works perfectly, and is very easy to use. I've already ordered a new battery, because I can tell from a simple check that my current one doesn't have too much life left in it. I suspected as much, and that is why I ordered it in the first place. Very easy to read and use.
