Raspberry Pi Micro-USB Power Supply 5.1V 2.5A + Heatsinks

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.

This listing bundles the supply with IoTCrazy heatsinks — self-adhesive aluminium pads that shed heat passively from the SoC and keep the board out of thermal throttling.

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
• Tight regulation — Minimal load and line regulation for dependable performance
• Heatsinks included — Self-adhesive aluminium pads for passive cooling
• Efficient — Minimum 80.73% efficiency across the 25%, 50%, 75% and 100% load points
• Protected — Short-circuit and overcurrent protection for both supply and board
• 1.5 m 18 AWG cable — Thick conductors keep the voltage drop low over a useful length
• US plug — White finish, standard North American two-pin plug
