The world's most portable professional power probe. Diagnose 12V-24V electrical systems with a tool that fits in your shirt pocket.

Professional Diagnostics, Miniaturised

The Autel PowerScan PS100 redefines what a circuit tester can be. Weighing just 30g, this ultra-compact tool eliminates the need for bulky handheld multimeters during initial fault isolation. Whether you are testing for ground, checking polarity, or measuring continuity, the PS100 provides instant, accurate feedback in a form factor designed for the mobile professional.

Built for the Modern Engine Bay

Modern vehicle engine bays are more cramped than ever. The PS100's slim profile allows you to access connectors, fuse boxes, and looms that traditional power probes simply cannot reach. Its integrated LED work light ensures you can see exactly what you are probing, even in the deepest recesses of a dashboard or undercarriage.

Versatile 12V/24V Capability

Designed for both passenger vehicles and heavy-duty commercial fleets, the PS100 handles 12V to 24V systems with ease. It features a high-speed circuit breaker for safety and a clear digital display that provides real-time voltage and resistance data. It is the essential 'first-response' tool for breakdown recovery drivers and workshop technicians alike.

Absolute game changer for roadside recovery. Fits in my pocket and replaces my bulky old probe. The LED light is surprisingly bright for such a small tool.

I work on HGVs and the 24V compatibility is flawless. It's so light that I don't get hand cramp when I'm probing a massive loom for an hour.

Great little tool for the price. The screen is clear, though I wish the cable was a tiny bit more flexible in sub-zero temperatures. Still, it hasn't let me down.

Finally a tool that fits into the tight fuse boxes on modern German cars. The accuracy on the resistance mode is spot on compared to my Fluke.

Excellent build quality. Dropped it on the workshop floor twice already and it's working perfectly. The UK support team were very helpful with my registration too.

Very handy for quick checks. It's so small I nearly lost it in my toolbox! Highly recommend for any mobile sparky.
