USB Current Adapters

The USB-IF is providing a limited number of USB current adapters to USB-IF member companies. The intent is to enable member companies to run power measurement as it is at the USB-IF compliance workshops. The goal is to aid member companies in identifying and resolving power issues prior to attending the workshop.

While our supply lasts, each USB-IF member company that requests a current adapter by email to will be provided one adapter at no charge. If you would like to purchase additional current adapters, please contact Stephen Kaplan with Elite Electronics, Inc. by email to

Supply is limited, so please respond as soon as possible if your company would like to receive a USB current adapter from the USB-IF. Again we will be providing one per USB-IF member company. Requests will be filled on a first come, first served basis.

You may download instructions for running Current Measurement at the USB Workshop.
