    Pros: Tested OK. I would use it for my portable SLA (sealed lead-acid battery) 12V battery to keep an eye on voltage during discharging and charging. Quite precision between 10V - 16V and that is range I really need. Surprised with low consumption - from my past experience LED display usually takes quite a lot- this one only about 15mA and doesn't matter if 10V or 16V. There is fine adjustment - miniature trimmer. Bright enough to be nice seen in bright daylight. Came even sooner than expected.

    Cons: There is description 'green' display and it is red. No problem for me, I like red better anyway.

    Other: Happy with this, will order more for my projects.

    Pros: Accurate to 0.1 volts total bright red and very simple to operate!

    Cons: I thought the screen is of medium size, but apparently it is small, No screw connection points. The minimum voltage is 3 volts but my LM317 can get to 1.2 volts with a false reading so below 3 volts, I must use my external voltage meter connected In parallel...

    Other: Good for home power supply... But if you want something serious, do not waste your $4 on this product...

    Involvement Level: Expert (understands the inner workings)

    Pros: The good voltmeter, with small ?????????? and exact indications. Bright and accurate figures, it is well visible and in the dark and on light. Only two occasions: plus and a minus, and a wide range of measurements from 3,2 volt To 30 volt. Very low price at such accuracy.

    Cons: Neznachitelnoe overestimate of indications in a range from 3,2 volt to 10 volt. In other range of measurement are exact to the one tenth volt.

    Other: Useful thing for electronics engineers of motorists and for various hobbies...

    posted by pfroozendaal on 06:53:34 G2T 19/02/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Exceeds specs of voltage range a little bit (2,6 - 35 V). Nice small and at least as accurate as my hobby DVM.

    Cons: Must still find a way to nicely incorporate it in my application. Lacks specifications: at voltages higher than 35V the display dims and switches of. What is the highest voltage before the device gets damaged?

    Other: Years ago I build a meter like this from discrete components, costing me at least $100,-. This one is better and I can hardly understand the low price! With my next DX order I will also try the Amps and the VAC meters. Can't wait.

  • Nice voltemeter, works as expected

    posted by bamsoft on 12:34:13 G1T 09/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Nice voltmeter that can be connected to a source without need of additional power supply. Can be adjusted to give accurate reading.

    Cons: Display is difficult to read unless you cover it with a red (plastic) transparent sheet. Supply current is fluctuating, may give unstable reading unless a capacitor is used. (see image)

    Other: ok

    posted by ligfries on 03:43:20 G12T 23/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Very easy to use, bright display and no external power needed. Accuracy is good enough (above 3.5 V). If you need absolute double digit accuracy go for something more expensive, but when 1 digit reliability is enough, this will do the job.

    Cons: Power consumption is quite high and non-adjustable. I measured about 20-22 mA irrespective of the measured voltage. Don't leave it "on" unattended, so either switch on/of with your device, or install a separate switch.

    Other: Great little device if you want to keep an eye on battery levels e.g. when used in combination with a dynamo like I have it in my bicycle. Might buy a couple more for other gadgets.

    Involvement Level: Expert (understands the inner workings)

    Pros: Bought this to put in a bench-top power supply... It's compact and accurate enough when compared to my multimeter. The display is good and it has mounting hole on the pcb. No external power required.

    Cons: Can't do negative readings, there must be some polarity protection in evidence. No matter, it suits my purpose.

    Other: I was going to build one, but for the price... it's a no brainer! I like its size and it seems well assembled

    posted by xsherlock on 01:58:07 G10T 15/10/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Small an bright, working fine from 3.7v up. The readout has 2 digit precision, contrary to some user pics.

    Cons: Not accurate below 3.7v, tried to use it as the voltage indicator for a single cell li-pol battery pack. And it works only half way. The spec claims from 3.2v up but at some 3.6 it will start hovering around 3.6 no matter how low the cell is. When the li-pol was totaly discharged at 2.99 it was still showing around 3.54v

    Other: Buy if you need a voltmeter from 4 volts up.

    posted by wurstsemel on 12:22:15 G9T 17/09/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - cheap - works even at lower voltage (3.0 Volts) - but maybe not exactly - no additonal power source needed - bright for daylight usage - small - easy installation - just connect the red and black cable to positive and negative DC

    Cons: - mounting points. The Voltmeter has two holes for installation, but they are small, and very close to the housing. You can use only bolts M2 or smaller, and even M2 nuts are hard to get on. Bigger holes and a wider pcb, so that usage of common M3 distances is possible would be nice - sometimes it flickers a little bit

    Other: Would buy again. Good.

    Involvement Level: Expert (understands the inner workings)

    Pros: Very small Quite Accurate Good readable display Wide voltage range

    Cons: High power consumption at high voltages

    Other: Very nice and useful voltage meter, ideal for automotive applications. But due to its power consumption it should not be connected directly to the battery, it could empty a car battery within a couple of weeks.
