USBpwrMe is a compact adapter that allows you to power any USB-powered device directly from your bench power supply. It includes multiple safety features and is designed to fit most laboratory power supplies.

When working with USB-powered devices, it is often important to monitor things like input current and power consumption, and USBpwrMe gives you a great deal of control. Simply connect your device via the USB Type-A or USB Type-C port on the adapter board, turn on your bench power supply, and you’re ready to start testing. The board operates from 3 V to 20 V, making it suitable for a wide range of applications, with charging negotiation when used at 5 V.

Power Up Your Workbench

USBpwrMe is an essential tool for electronics development, testing, and troubleshooting. For anyone who needs to power prototypes as they’re developing custom hardware.

Quickly plug in and troubleshoot a wide array of USB-powered devices—it lets you sanity check your latest board revision and monitor its power draw in seconds.

With the flexibility and convenience of USBpwrMe, you’ll never have to search for matching cables and connectors again. There’s no need to cut or modify cables to connect to your bench power supply. Simply connect your DUT and forget the frustration of cutting up your last USB cable.
