Frequently Asked Questions
Q: Is this power adapter compatible with Raspberry Pi 4?
A: This 5V 3A Micro USB power adapter is specifically designed for Raspberry Pi 3B and 3B+ models that use a Micro USB power port. The Raspberry Pi 4 uses a USB-C connector and requires a different adapter, so this unit is not recommended for the Pi 4.
Q: What does the inline switch button do?
A: The inline on/off switch lets you power your Raspberry Pi on or off without physically unplugging the adapter from the wall. Simply press the button once to start supplying power, and press it again to cut the power — making it easy to restart or shut down your board safely.
Q: Will this adapter work with my country's wall outlets?
A: Yes. The adapter accepts universal AC input from 100V to 240V at 50/60Hz, covering wall outlet standards across the EU, US, UK, and AU. Multiple plug types are available, so please select the correct plug type for your region when ordering.
Q: Is the 3A output enough to run Raspberry Pi accessories?
A: A 3A output at 5V provides 15W of power, which meets and exceeds the official Raspberry Pi Foundation's recommendation for the Pi 3B and 3B+. This gives you headroom to power USB peripherals, HATs, and other connected accessories without causing under-voltage warnings.
