This handy little adapter lets you convert male USB micro-B to USB-C, just the ticket if you want to use a micro-USB power supply with your Raspberry Pi 4*.

*Ensure that your micro-USB power supply is capable of supplying the required current and voltage necessary for the Raspberry Pi 4. We've found that the older official Raspberry Pi power supplies (5.1V/2.5A) work fine with this and the Raspberry Pi 4.
