PonJel PJ-U37-01 USB-C Power Meter

The PonJel PJ-U37-01 is a USB Type-C male-to-female adapter with an integrated LED display that shows real-time voltage, current and power up to 240W. It supports data transfer at 80 Gbps and 8K video at 60 Hz. The two-pack includes a lanyard for portability.

For engineers and enthusiasts checking USB-C power

Suits anyone who needs to verify that a charger, cable or device is negotiating the correct power profile up to 48 A. Not for users who require automated logging, software control or multi-port simultaneous measurement.

Plug-and-play installation with a lanyard

Insert the adapter between the host and the cable; no drivers or software are needed. The only common issue is forgetting that the display draws a small current, which can slightly offset idle-power readings.

Questions about this item

What must I already have to use the PonJel PJ-U37-01 power meter?

You need a USB-C cable with a male plug on one end and a USB-C device or charger on the other; the meter sits in-line between them.

Does the PonJel PJ-U37-01 meter limit the speed of a legacy 10 Gbps USB-C drive I still use?

The meter supports up to 80 Gbps, so a 10 Gbps drive will run at its own rated speed without being bottlenecked.

How can I verify the PonJel PJ-U37-01 is showing live power data after I plug it in?

The built-in LED display instantly shows voltage, current and watts; confirm the numbers change when the attached device starts or stops charging.
