  • Perfect

    posted by MarekNovak

    Works great, ideal stability of displayed value. Display (red LED) is very readable during the day and not disturbing at night.USB power source works, but get little warm during charging of mobile phone. (But it is OK)
    Current consumption is 10 mA at 12V, and about 6 mA at 24V. (when USB is empty).Displayed voltage is 0,1V smaller than actually is at 12V and at 24V it is accurate.Minimum operating voltage is 5V.
    Great stuff for me.
  • very usefull (during winter), cheap and effective

    Cheap, accurate, handy and easy to use. Looks good too. Fits every car with a cigarettelighter. Parts are even easy to build in your dashboard. Some technical knowledge demanded.
    took some time to arrive. I had to contact DX several times, but in the end the pakkage was delivered. Feedback was friendly and o.k. Thanx
    Must be in your car. Quick check-up of your battery-status and the working of dynamo. In wintertime, when Powerconsumption of your car is high, you won't be surprised no more with a flat battery.
  • Nice DC ammeter/Voltmeter

    posted by Rimlyanin

    This device is small in size, without using an external shunt accurately measures the volts and amps in your circuit. Ammeter and voltmeter can be calibrated independently of each other for this purpose on the rear side of the device has two trimming resistor.
    The ammeter measures the voltage drop across the internal shunt resistor , which is not always possible to get a fairly accurate reading.
    Good quality / price ratio . To use such control circuitry .
  • good stuff to use

    cheap, very small, you can put it into the motorcycle that doesn't have big space, into dashboard, very clear to read the number. no additional power needed. it's good packing
    manual is important to have in this case, because there are many pins
    not bad for price, good quality enough...you can add to your car or motorcycle for indicating the voltage
  • Does the job

    Works well and are accurate.Easy to make attach into your dashboardVery simple to connect into your car or whateverproject you are using.
    A good value item
    I use two of those in our off-road car. One for the 24v system and one for the 12v system.They are accurate and the 24v shows the 12v x2 which is correct since there are two 12v batteries connected to each other. Measured it and found that it was accurate down to 0,1 volt. which is enough for most people.
