Aicevoos 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 tester is great value for money in my opinion.It comes boxed with instructions which are simple to follow and after testing on a few things works really well.You turn it on and move it to where you think there might be power, if detected it beeps loudly and flashes. I tested this on sockets, computers and lamps; it works flawlessly.Highly recommend.Added bonus it has a torch built in so you can see what you are doing in that loft and a laser pointer to point out things to the wife!

Neat little gadget that helps track down live wires and minimise the risk of an electric shock. Great price as well. Seems to be accurate and a quality product for the price

When I had worked out how to switch it on (hold the power button for a few seconds) - it works great! Pretty sensitive (has a high and low range) and was consistent at tracing a live circuit. Compact and durable.

Voltage pen does the job! It is quite intuitive to use, and the instructions are easy and clear. I had an issue with electric circuit and was able to sort it out with help of this pen 😊

Worked really well.Well made

Not as clear as I expected

Nice piece of kit at a great price. Large pen size, clips to pocket. Simple to use. Light and noise let's you know if a line is live. Much better and easier than using a multi-meter to check if a line or socket is live.
