Great real-time monitor for elec/charging system

Plugs in and tells me precisely what the battery charge and alternator activity are. Acts like the old-time dash amp meter used to (don't know why the manufacturers eliminated that). Switch from car to car to check charging situation. It seems very accurate.

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.

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.
