USB-C Power Meter Tester KWS-1902C – 4–30V 0–5A 150W Bidirectional with 0.96" Colour Display

The KWS-1902C USB-C Power Meter is a compact inline tester that shows exactly what is flowing through a USB-C connection. Plug it between a charger and a device to read voltage, current, power, capacity and energy in real time on its 0.96" colour display.

It handles 4 to 30V at up to 5A (150W) and measures in both directions, so it works with chargers, power banks, laptops, phones and USB-C powered projects. Use it to check whether a charger is delivering its rated output, compare cables, measure battery capacity, or troubleshoot a device that charges slowly. An animated arrow shows the direction of current, changing colour and speed as the current rises.

How to Use

1. Change display page: press the button once.
2. Rotate the screen: double press the button.
3. Clear saved data: hold the button for 3 seconds.
4. Current direction indicator: the arrow shows which way current is flowing. Its colour changes from green to yellow to orange to red and it scrolls faster as current increases. No arrow is shown when there is no current.
5. Calibration: connect a precise 5.000V source, then hold the button while powering on. Release the button when "Factory setting" appears and the meter will calibrate automatically. Do not connect any load during calibration.
