WUQ PowerScan Automotive Circuit Tester 12-24V 20FT Extension Cord

All-in-One Circuit Tester Kit

The WUQ PowerScan is a 2025 all-in-one power circuit tester kit built for automotive electrical diagnostics. It covers 6-30 volt vehicle systems with a 160x128 TFT display. The package includes the probe itself with a 20ft cable plus an extra 20ft extension cord for reach. Technicians and enthusiasts can perform voltage, polarity, continuity, resistance and component activation checks with one tool.

Suits Techs Needing Component Activation

This kit suits professional technicians and serious DIYers who need to activate components such as fuel injectors, wiper motors or cooling fans directly from the probe. It also fits shops that want instant polarity identification through red and green LEDs with audible tones. Buyers who only need a basic 12-24V test light for simple continuity checks will find the feature set excessive. Users requiring oscilloscope-level waveform capture or CAN bus decoding should look at a dedicated diagnostic scanner instead.

Plug-and-Play With Long Reach

Installation is straightforward: connect the probe to the vehicle battery using the supplied clamps, then use the 20ft built-in cable or add the extra 20ft extension for access around the chassis. The four working modes — DC voltage, AC voltage, resistance and tone — are selected on the probe body with no software setup. Common issues include accidental activation of the tone mode in bright daylight where the audible cue is hard to hear, and forgetting to switch the ground reference when moving between positive and negative circuit tests.
