    $8 on Temu
    Probably from the same manufacturer
    I bought one when it was 50% casback.
    Very sensitive.

      I have three of these and would never rely on a cheapy!
      All three are made differently and have different designs.
      The cheapest which I bought was still double the cost of yours would turn off by itself due to less than adequate battery connections.
      Maybe just bad luck but would you fly in a Temu aeroplane?
      With certain things that can hurt you I just think spend a few dollars and be safe

    • noise36 on 11/07/2025 - 08:58

      Isnt everything on amazon just resold stuff from sites like Temu/Aliexpress etc with big markups?

    Terrific product at a great price. This for $21 delivered is unheard of.
    Very reliable and easy to use.

    If you're testing 240v circuits before working on them, I wouldn't be trusting a Temu/Ebay knock off.
    Buying from Amazon means buying genuine. Don't stuff around with 240v.

    • teacherer on 10/07/2025 - 14:52

      Or… don't trust a Non Contact Voltage Tester Pen with 240v

      • whitey on 10/07/2025 - 15:12
        +26

        Yes, I'm a qualified sparky and I have the "Fluke" version of this. I have had quite a few false positives with these non contact testers, but never a false negative. False positives are usually caused by an induced voltage on the circuit ie. a live circuit running next to a disconnected circuit and voltage is transferred to the disconnected circuit through electromagnetic induction. To prevent this, place a load on the circuit being tested (Eg. light bulb) A multimeter can also show induced currents, not just these non contact testers. If you don't know what you're doing with 240V, get someone who does. Safest way to use these is to hold near circuit and cycle the power few times just to be sure the tester is working and the circuit is powering down.

        • bongoman on 10/07/2025 - 16:25

          i poke it at the light switch and then over to the 'dead' circuit - 2 times back and forth to make sure its on and safe….

          but they say safe is completely isolated….. so dont blame us if you die…..

        • Thrifty McGifty on 10/07/2025 - 18:37
          +1

          I'm not a sparky, but wouldn't hooking up a light globe to the circuit negate the need for the tester?

        • kongkurr on 10/07/2025 - 18:39
          +4

          For any electricians or budding elec engineers reading:

          Instead of induction, you mean capacitive coupling. The tester measures voltages, not current, so it tests for electric fields around a conductor, and not magnetic fields caused by induction.

          Adding a load won't remove capacitive coupling in a dead conductor for means of testing. However when using a multimeter, you want to use a 'LoZ' mode, which applies a low impedance load through the meter - low enough that a capacitive effect is dissapated between the test leads.

      • R4 on 11/07/2025 - 12:24

        Nothing wrong with using this tester as a quick check but always confirm a reading with a contact tester - multimeter or Duspol type tester.

    • Jimothy Wongingtons on 10/07/2025 - 14:59

      i paid closer to $40 iirc - but only use it to triple check circuit is not on. Makes fault finding even for low voltage circuit easier.

      You can't always get genuine products on Amazon even if it says sold by Amazon. Amazon is just a marketplace in essence. I mean most of the products are good but I've bought counterfeit stuff from Amazon before.

    • Leeroy Jenkins on 10/07/2025 - 18:59

      I wouldn't rely on a NCV detector to check presence of high voltage. I've had the same thing from Fluke fail me. I'd always use a quality multimeter/tester to be sure.

  • MattyD on 10/07/2025 - 15:05

    Why not spend an extra $10 or so and get a (well-reviewed, from what I've seen) digital multimeter that can do this and more like the ANENG 681?

    I bought this based on a fellow-OB recommendation and it has been brilliant. Watched a few good teardown/review videos before buying, and I think I got mine on special for about this same price, when it comes up.

    • AngryAlfred on 10/07/2025 - 16:01

      Very annoyed that you tell me this exists when it's cheaper than what I've spent on my cheap multimeter, extra cords and connectors, and non contact tester combined…

      Is the battery replaceable on the 681? Manual makes it sound like it’s not, but wanted to double check. Thanks.

  • Mnke on 10/07/2025 - 15:08

    It is too sensitive for my liking. You see demonstration videos where it would go off when inserted into the power point slot.

    When I tried that and it was near the outlet, it would start going off.

    Maybe it is more suited to 120V in the US.

    I did have it set to the higher voltage setting.

      just pull fuses each time you stop

    • Austrian Oak on 10/07/2025 - 16:41

      Just use a cheap multimeter and measure the voltage drop acrosss your fuses to find which circuit is causing the drain.

      • Thrifty McGifty on 10/07/2025 - 18:39

        Please explain further? You wouldn't get voltage drop across a fuse. Don't you need an ammeter to find the current?

        • Davo1111 on 10/07/2025 - 19:08
          +1

          im pretty sure hes talking about using the current function. Removing the fuse, stick in the probes then measure the current.

          • Austrian Oak on 10/07/2025 - 19:44

            @Davo1111: This video will explain it well. You basically measure the voltage in mA between each fuse, it should be zero, if it is not then you have a parasitic draw. You can then compare the measurement to a chart to see how much amperage that circuit is pulling.

      Yeah I've found this as well. I get around it by getting stuff sent to my daughter who lives in Wagga, that always works. It's only an hour away and someone is usually traveling there, worth the effort for the real bargains but not so much for the average ones.

  • iNeedMoreMoney on 10/07/2025 - 18:06

    Sorry I don't know much, but Bunnings sells a non-contact voltage tester for $8.98. Would it work just as well? I mean apart from all the other functions.

  • bumpyhead on 10/07/2025 - 18:10

      To check if the power to a wire or socket or device is truely off and that there is no charge running through the circuit.

  • mauricem on 10/07/2025 - 18:19

    Would this be more reliable than a multimeter like the UNI-T UT139C with NCV ? https://meters.uni-trend.com/product/ut139-series/

  • Bigsta on 10/07/2025 - 18:21

    I Initially thought this was dual voltage AC/DC which would be a great price but not that good for a standard AC tester even if it does pick up down to 12v which is likely to be induction anyway, not many low voltage things run on AC.

    This one for $7.50 will do the same job really

  • R4 on 11/07/2025 - 12:17

    I'm an electrical person. I have this tester and it's good. I would avoid buying a Temu knockoff - you're testing electricity (which, obviously, can be dangerous), not whether something is sweet or sour. This tool does the job but always, always confirm a reading with a multimeter or contact type mains tester (Duspol).

    • Pusdi on 14/07/2025 - 20:55

      Why not just use the multimeter to begin with?

  • R4 on 14/07/2025 - 21:01

    Sure, but say you had to fix a socket outlet that wasn't working, using one of these would immediately confirm if there was power there, thereby eliminating one potential fault.
