When it comes to powering your Raspberry Pi, there’s really only one way to do it – the official Raspberry Power Supply.
If you want to guarantee a steady, quality supply of power to your projects without drop-outs or random restarts, we strongly recommend using the power supply that was designed for the board, by the same people who designed the board.
All models of Raspberry Pi now use the same universal power supply, which offers 5.1V @ 2.5A. This will happily power all flavours of Raspberry Pi - from original boards right through the range to the most powerful Raspberry Pi 3 Model B+.
Don’t risk it – get the right tool for the job!
