aFe Power KWS-2303C USB-C Tester

The aFe Power KWS-2303C is a USB-C power meter and digital multimeter designed for electrical system diagnostics. It measures voltage from 4 to 30V and current up to 12A, providing real-time data on charging performance. The device includes a storage case and user manual for immediate use.

Suits technicians and enthusiasts checking USB-C

This tester suits technicians and enthusiasts who need to verify charger output, power bank capacity, or cable quality on Type-C ports. It supports PD2.0/3.0, QC2.0/3.0, FCP, SCP, AFC, PE, DASH VOOC and Super VOOC protocols. Builders requiring Micro-USB or USB-A connectivity should look at a different model, as this unit only offers a Type-C connector.

12A maximum current rating

The single specification that decides fit is the 12A current measurement ceiling. Circuits drawing more than 12A will exceed the meter range and require a higher-rated instrument. The 360W power range and 30V voltage limit align with this current rating for USB-C power delivery testing.

Questions about this item

What does the 12 A current limit mean when I plug this tester between my charger and phone?

It means the tester can safely measure up to 12 A of current flowing through the USB-C connection, so it will handle even high-power laptop chargers without saturating.

Which fast-charge protocols does the USB-C port actually negotiate and display?

The unit detects and shows PD 2.0/3.0, QC 2.0/3.0, FCP, SCP, AFC, PE, DASH, VOOC and Super VOOC handshakes on its screen.

How does the tester mount in a tool bag or on a bench?

It comes with a compact aluminium shell and a fitted storage case that slides into a pocket or sits flat on a workbench.
