A1 Voltage Tester/Non-Contact Voltage Tester with Range AC 12V-1000V/48V-1000V, Live/Null Wire Tester, Electrical Tester with Flashlight, Buzzer Alarm, Wire Breakpoint Finder

I picked up the Aicevoos A1 voltage tester to help with some electrical DIY work at home, and it’s been absolutely brilliant. It’s one of those tools that you don’t realise how useful it is until you start using it — now I keep it in the toolbox at all times. It’s a non-contact tester, which means you don’t need to touch any wires directly to check for voltage. Just bring the tip near a live socket, wire, or outlet, and it gives you a clear signal. It lights up, beeps, and makes it very obvious when voltage is present. This feature alone is a real game-changer when working safely, especially in tight or awkward spaces. The A1 model feels solid and well made. It’s lightweight and shaped like a pen, so it fits easily in a pocket or tool belt. The clip is a nice touch too, making it easy to carry around the job site or home without misplacing it. One of the standout features is the sensitivity range — it can detect voltages from 12V to 1000V AC, which makes it useful for all sorts of applications from basic home electrics to more advanced circuit testing. It also includes a low/high sensitivity mode, which is very useful for picking up low-voltage circuits like doorbells or thermostats. There’s also a handy built-in torch at the end, which is surprisingly bright. It’s been great for working in fuse boxes or dark cupboards where lighting’s poor. Only minor thing to watch is that it beeps quite loudly, which is great for noisy work environments, but might be a bit much if you’re testing in a quiet room. That said, it’s better to be safe and have clear feedback than not notice at all. Battery life is excellent — runs on a couple of standard AAA batteries and doesn’t drain them fast. I’ve been using it for weeks now and still on the original set. In short, this is a fantastic little tester. Accurate, reliable, safe, and perfect for DIYers or even professional electricians as a quick-check tool. Highly recommended for any toolbox.

This is a great little tool. It effectively replaces my "electrical" screwdriver, and it is far safer and much more reliable. I think everyone should have one, if you ever have a need to test for live cables. It could be life saving!

I’ve been using the Aicevoos A1 Voltage Stabiliser to protect my laptop and external monitor from power fluctuations, and it works well. The output stays consistently around 230 V—even when input voltage dips—with minimal noise and stable operation. What I like: Solid voltage regulation — keeps output within 10 mV, giving me confidence during unexpected surges or drops Durable build — feels sturdy enough for office or home use Easy setup — just plug it in and switch on, no complicated installation Summary: The Aicevoos A1 offers reliable voltage protection and is easy to use. It’s ideal for anyone who needs to safeguard electronics from electrical fluctuations. Great value for money!

Great does the job, good value for money

Brilliant voltage tester to use when working on any electrics safely touch the area you think might be live voltage with the tip of the voltage tester if live current the tester lights up . this tester could easily save your life well made and compact.

As described. Simple to use. I'm still alive so that's some sort of evidence that it works OK. Too soon to comment on durability (device, not me - I'm an old bird).

Really handy tool for DIY projects. I used it while changing a house switch to check for live wires, and it did the job perfectly. I did notice that sometimes the detection can be a bit too sensitive. it occasionally triggers even without direct wire contact. The AAA battery is replaceable, so no issues there. The built-in torch and laser pointer work very well too. Overall, a must-have tool for any DIY enthusiast and great value for the money.

Excellent product and fast delivery.
