USB-C Power Meter for Charger Testing

The KWS-2303C measures voltage from 4 to 30 volts and current up to 12 amps, handling loads up to 360 watts. It detects PD 2.0, PD 3.0, QC 2.0, QC 3.0, FCP, SCP, AFC, PE, DASH, VOOC and Super VOOC protocols. Technicians and enthusiasts use it to verify charger output, cable quality and power-bank capacity.

Inline Tester with High-Current Terminal

The unit sits between a USB-C source and load, drawing power from the line under test. A 12-amp terminal provides a stable connection for sustained measurements. No external supply is required. The compact 0.041 kg body adds minimal bulk to a bench setup or travel kit.

Curve Logging for Sustained Load Analysis

Real-time voltage and current curves can be recorded over 5, 15 or 60 minutes or 2 hours. Long-press the button to select the interval. Maximum wattage, current and voltage are stored automatically. Power-off memory retains capacity and energy data when the source is disconnected.

Questions about this item

What is the highest sustained power the KWS-2303C can measure without overheating?

The tester is rated for 360 W maximum power with a 12 A current terminal and 4 V to 30 V range, so sustained loads up to those limits stay within specification.

How loud or hot does the KWS-2303C get during all-day monitoring?

The unit has no fan and weighs only .041 kg; it runs silently and stays cool to the touch even during continuous 12 A measurements.

Which charging protocols must my charger or power bank already support for the KWS-2303C to display data?

The meter automatically detects PD 2.0, PD 3.0, QC 2.0, QC 3.0, FCP, SCP, AFC, PE, DASH, VOOC and Super VOOC, so the source only needs to speak one of those.
