    I think it is better to take things out on an object than kicking the dog, since this is a perfectly adequate tester with voltage readings that compare favorably with my tester.


    This tool was very useful, but don't use it if you're supposed to be watching the road.


    The product display is easy to read and has a soft blue color, but I found the battery meter to jump around quite a bit when I was driving, going from a very strong charge (green) to a questionable charge (amber) within moments.


    It was easy to plug in and read the voltages, it has a blue backlight, and I wish I could leave it plugged in 24/7.


    This is an excellent tool, it is quick and accurate, and it can be used on other vehicles as well. I did a test with it on another vehicle, and it gave me trouble, but it was dead on.

    Question & Answers

    Q:

    Is this a good thing to have in a camper that is running on a 12V battery?

    A:

    I think this meter can give you a good idea if your bat is working.

    Q:

    Is a live outlet required when the engine is off?

    A:

    It can only measure live voltage, but many 12v outlets in cars are live with the key/engine off.

    Q:

    Does it show the current of the engine when it is cranking?

    A:

    When you turn the key on, it shows the voltage as soon as you step on the pedal, but blanks out while the engine is cranking and comes back on as soon as the car starts.

    Q:

    Is the readings correct?

    A:

    The readings vary from my tester a little by a few tenths but it could be because one reading is at the battery.

    Q:

    Does it show the battery's voltage or can it actually test the battery?

    A:

    I believe the indicators are based on the voltage level, but I don't know.
