About this product
Overview
A Raspberry Pi is only as stable as the supply feeding it. This IoTCrazy 5.1 V 2.5 A micro-USB power supply is built for every Pi model that uses a micro-USB power input — Pi 3 B+, Pi 3, Pi 2, Pi 1, Pi Zero, Pi Zero W and Pi Pico.
The slightly elevated 5.1 V output is deliberate: it compensates for the small voltage drop along the cable so the board still sees a clean 5 V under load, which is what prevents the low-voltage warning and the SD-card corruption that follows it.
An inline ON/OFF switch saves the connector from constant plugging and unplugging — a small thing that makes a real difference on a board you reboot often.
Key Features
- Broad Pi compatibility — Raspberry Pi 3 B+, Pi 3, Pi 2, Pi 1, Pi Zero, Pi Zero W and Pi Pico
- Stable 5.1 V output — Compensates for cable losses so the board sees a full 5 V under load
- 2.5 A of headroom — Enough for the board plus typical USB peripherals
- ON/OFF switch — Power-cycle without pulling the connector
- Tight regulation — Minimal load and line regulation for dependable performance
- US plug — White finish, standard North American two-pin plug
