This "Innova" battery monitor is a quick way to check your "battery voltage" and "alternator voltage" all in one package. Before starting your car (when the car is not running), this monitor easily plugs in to your cigarette lighter, and you get an instance display of your car battery voltage. As you see in my picture, it show's 12.70 and a "green" light, indicating "full voltage". "Yellow" light would indicate "low voltage" between 12.1 to 12.4 volt's in your battery, and "Red" would indicate, get help quick before you drain your battery and "time to locate the problem". Then while the engine is running/driving you will see the "voltage display" spike in voltage (13.3/14.4)green light, indicating " your alternator is working ", anything below 13.1 yellow light and a big red light 12.6 you might need to check your alternator or just use the helpful quick tip's included in package, to locate your problem. Great battery monitor to have onhand and can be used/switch from car to car to check your charging situation, in any vehicle. with a cigarette lighter. This would make a great gift, for the car gadget's person.

Customer reviews & ratings
An inexpensive way to monitor my RV batteries , very accurate when i compare volts with my Zamp portable 180W panels. While i am using power inside i can see dips in the monitor keeping my usage in check
My volt meter in my 03 Silverado 1500 HD quit working about two years ago, I checked battery and alternator voltage peoridocally with my multimeter, but it was unerving to be miles from home and not have constant monitoring as I pull a 25' fith wheel camper, now in excess of 90,ooo miles across the US and Canada. (yes ninty housand) tip-use 3rd gear not drive. I was doing a intrnet search lookind for a better way than replacing the instrument cluster, when I saw this device which plugs in the lighter receptical, reading the instructions, specifications and reviews, this shoud work great. and it does, very happy with this product. ordered on line from Wallmart, it arrived at my local store in bout one week.
Exactly What I Needed
My Hyundai Genesis was giving intermittent "Battery Discharge Warning" error messages. The car does not have a volt meter & the dealer said everything tested fine. So I purchased the Equus Innova 3721 volt meter & plugged it into one of my power ports. It didn't take long for this little device to pinpoint that the Genesis charging system does not charge based on electrical load but rather on operating settings. So far the only times I have observed it charging are when the headlights are on or if the headlights are off, when the car is coasting with a closed throttle at speeds greater than 5 mph. So now I burn the headlights on all the time, the system charges all the time, & I have not seen any more error messages. The volt meter was well worth the $10 it cost.
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.
