    The use is very simple. Just put in 12V and they show the voltagem. The price is acceptable, because they work and safe you to get without power to turn the engine. Could be less expensive. I cut the cable of one and put direct with 12V from battery to monitor the state of sound battery (hi-power car sound). i hope the this still working for a long ... Read more

    This little guy is bright, consumes very little power, is large enough to read from across a room, but small enough to wedge into a small corner. The cable is rather short. It doesn't work if wired up backwards. I use this as a quick and dirty battery monitor on my off-grid batteries. It seems to disagree with the voltage from my meter, but consistently ... Read more

    This is a pretty straight forward devce. Plug it into the cigarette lighter power plug, and it'll give you a voltage in the LED display. The accuracy isn't 100%. It's off by about 7% in my car, but as a rough gauge, it is fine enough. The plug is a bit brittle and feels like it may break if you have to apply a lot of force to pull it out. It's a bit ...

    Very compact unit with power cord approximately 12 inches in length. I've used it to measure voltage of a lithium cell just to ensure that it works out of the box and it measured the voltage accurately given that it was a single cell (3.7V). Since I have an audio system in the car and often times play music with the car engine off, it's critical to ... Read more
