WattBench turns your iPhone into a wireless display, data logger and test bench for the FNIRSI FNB58 USB power meter. Connect over Bluetooth and watch voltage, current and power live. See what your charger is doing on the USB data lines. Record a whole charge cycle with the phone locked. Then run guided tests that answer real questions: how much a power bank actually holds, how fast a phone really charges, and whether a cable is wasting power. LIVE • Big, glanceable voltage, current and power
