STARTECH USB-C Power Tester USBC-PWRTESTER 240W EPR
Measures USB-C voltage, current and wattage bi-directionally up to 240 W with a 180° flip display and 10 Gbps data pass-through
- Bi-directional testing measures power flow in both directions
- 180° flip display reads clearly from any angle
- Supports 240W USB PD 3.1 EPR for high-power devices
- Pass-through up to 10Gbps data and DP Alt Mode video
- Operating range 4.5V-50V, 50mA-6.5A covers diverse USB-C sources
What it is and who it is for
This compact USB-C power tester measures voltage, current and wattage in both directions through a bi‑directional Type‑C connector. A digital display with 180° flip rotation gives real‑time readings for IT professionals and technicians who need portable verification of charging stations, cables and bus‑powered devices. It supports USB 3.2 Gen 2 data pass‑through at 10 Gbps including DisplayPort Alt Mode video.
Practical limits of the USB-C interface
The tester operates within a 4.5‑50 V and 50 mA‑6.5 A range, capping measurement at 240 W under USB Power Delivery 3.1 Extended Power Range. It cannot measure beyond those voltage, current or power boundaries, and it does not test protocols or cables that fall outside the USB‑C PD 3.1 EPR specification.
What it replaces and when the jump is worth it
It replaces guesswork with multimeters or single‑direction dongles when diagnosing VBUS drops, validating high‑power delivery or confirming cable compliance. The upgrade is justified whenever bi‑directional visibility, 240 W headroom and 10 Gbps data transparency are required for troubleshooting modern USB‑C ecosystems.

Questions about this item
Should I choose the 240W EPR model or a lower-wattage tester?
This tester measures up to 240W USB Power Delivery 3.1 Extended Power Range, so select it when you need to validate chargers, docks or cables that operate at the full EPR limit.
What does the 240W figure mean when I plug the tester between my charger and laptop?
It shows real-time voltage (4.5V–50V), current (50mA–6.5A) and calculated wattage up to 240W, letting you confirm the charger actually delivers the negotiated EPR power level under load.
The tester has USB 3.2 Gen 2 10 Gbps ports — what does that cap in practice?
Data passes through at up to 10 Gbps with DisplayPort Alt Mode video support, while the measurement circuit handles 4.5V–50V, 50mA–6.5A and 240W PD 3.1 EPR simultaneously.
