Not Bad good product BUT ?,
Amazon Verified Purchase(What is this?)
This review is from: Mini LED Display Digital Car Volt Meter 12V/24V Vehicle Voltage Gauge (Misc.)
Bought this on good reviews, but just wish. And I should have realized, that if you need to put your car ignition on to power up your cigarette socket, you wont get a proper reading, as the battery is now drawing power to glow plugs fuel pump etc. I was getting 11.7 v. Like this.
But when I used this, ( Link below Or copy paste) and connected dirtily to the battery.
I was getting 12.4, So if you need to put your ignition on to power your cigarette socket, you would be better off with something like this. (Link below)
As you will get a more accurate reading.
