  • Great little voltmeter.

    posted by Crowbot

    Crystal clear, vivid red LED display. Easy to use. Accurate and handy. Red light LED display are great because they don't interfere with your night vision/eyes; unlike blue or white light.
    This thing is tiny! Not that thats a bad thing. It's just about as long as your thumb is wide.Good quality. Just hook it up properly and you are set.
    Great little voltmeter. I bought it to install into my motorcycle to track actual voltage from the battery. Really handy gauge to have.
  • Great quality component!

    Nicely built compact adjustable voltage drop adjustable. Switch allows to view input and output in a nicely sized display. Adjustment screw is nicely sized to not be easily mis-adjusted. Voltage display switch is also conveniently located.
    Comes with stand offs and build quality appears to be very good. Using this drop a 12 volt gel cell down to 5 volts for a remote camera.///////////
    Great value for a well built component. Set screws for lead attachment appear to be quality and tighten down snuggly. I found that an oversize plastic TicTac box makes a good case to mount the regulator in.
  • Very good product!!!

    The "V20D-T1 0.36" LED 3-Digital Voltmeter - Black + Green + White (DC 3.2~30V)" device is good. I attached some photo, and one video. The measurement is precise. It may the precision of the voltmeter to calibrate with the potmeter (bottom side). I calibrated it. The product is very cheap. It luminous intensity of the voltmeter is very strong. The color of display is reed.
    The device is very cheap, good, and exact. I offer it!

  • Small and practical, but not very accurate.

    A small and practical module. It can easily be mounted.
    I thought that it would work the same as sku187376 only with extra power supply, but it was way more inaccurate. If you only need measurement from 2,5V to 30V i recommend sku187376 instead.
    The measurement range of 0-100V make it inaccurate. It varies about half a volt.
  • Fast delivery, works well and value for money

    I ordered this power booster on 28th Nov and I received it on 6th Dec in good condition. Took slight more than 1 week which is consider very fast.I connected the input to my 12V DC battery which is charged up by solar panels. I adjusted the output to 17.2V to charge my Philips electric shaver. I measured the actual voltage using Digital multimeter and found it to be 17.13V which is close enough.The stands are in rubble which help to prevent from short circuit. The LED display is bright and clear.
    It would be good if it comes with plastic enclosure.
    Fast delivery, good product that suits my needs.Highly recommended.
