Digital USB Charging Tester - Connector Options

See what is happening along a compatible USB charging connection. This inline digital tester displays electrical readings between a suitable power source and device, with USB and Type-C connector options.

✅ Check voltage and current during charging - The inline display shows readings while the connected load draws power.

✅ Compare a charging setup with visible data - Power and accumulated readings add context when checking compatible chargers or cables.

✅ Choose the connectors for the connection - USB, Type-C and combined options match different charging arrangements.

Read the Connection While It Works

A charging indicator on a phone does not show every electrical value. An inline tester gives the connection a separate display, helping you compare readings when changing a compatible cable or power source under similar conditions.

Match the tester's exact input/output direction and current limit to the setup. The Type-C version requires a connected load to display. Accumulated input readings are not a direct battery-health test, and the tester does not make an unsupported charging protocol compatible.
