Accurate, Detailed, and Perfect for Power Testing
Excellent tool for monitoring USB power delivery in real time. The display is clear and easy to read, and it provides detailed data including voltage, current, wattage, accumulated mAh, and Wh. I’ve used it to test chargers, cables, and device draw under load, and the readings have been consistent and reliable. The PD/QC trigger functionality is a big plus for stress testing and verifying fast-charge negotiation. Build quality feels solid and it handles higher wattage without issue. Great for anyone who likes understanding exactly what their devices are pulling.

Not testing as per specs given
As mentioned max measurable voltage / current 26V - 6.0A in specs, but measuring max. 20V - 3.1A = 63W (PD3.0 PPS) while charger can supply 20V - 5A = 100W.
