Frequently asked questions
Is 3 A enough for a Raspberry Pi 3?
Yes. The official recommendation for the Raspberry Pi 3B is 2.5 A, so a 3 A adapter gives extra headroom for USB peripherals.
How do I connect it to the Raspberry Pi?
Connect the adapter's output cable to the Pi's power input, which is micro-USB on the Pi 3B. Use the ON/OFF cable's switch to power the board on and off, and follow the product manual if the cable has a different connector.
