QuantaPulse USB-C Power Meter

Stop guessing whether a charger or cable is actually doing its job. QuantaPulse sits in the USB-C path and shows the voltage, current, and wattage moving through it — on its own display, no app or battery needed. • Measures 3.0–21.0V, 0–5.0A, and 0–105W, updating several times a second with smoothing • USB-C pass-through connectors for observing USB Power Delivery negotiations • A pocket-size 18 g aluminum body in Black, Silver, or Teal Slip it inline, reconnect the source and device, and give it 10–20 seconds to settle before reading. Compare one cable or adapter at a time so you know what changed. It observes electrical values — it won't regulate output, fix a bad charger, or certify a cable — and a loose or hot connector is your cue to stop. Handy for repair benches, travel-kit checks, and USB-C tinkering.
