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

Very useful item. Never failed. Used to test for live sockets before lugging equipment around a job site and used before working on or near cables/power sources. Great sensitivity. Good price. Easy to use. Battery is down to brand used of course.

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.

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!

Really good can test if there is power by putting the probe in the plug socket

Great,works well , no more getting electrocuted, happy days

I can't believe that I haven't bought one of these before! Incredibly useful and so easy to use. You honestly don't need to spend more, this product is awesome.

Works well, only used a couple of times. Does what it say on the package

Appears to work okay now I’ve replaced the corroded batteries it came with.
