Official Raspberry Pi 4B Power Supply + 3 Heatsinks, White

Overview

This is the official Raspberry Pi USB-C power supply, designed specifically for the Raspberry Pi 4 Model B and Raspberry Pi 400. The Pi 4 is noticeably fussier about its supply than earlier models, and using the official adapter is the simplest way to avoid under-voltage warnings, random reboots and corrupted SD cards.

It delivers a steady 5.1 V at 3.0 A over a captive USB-C cable, with short-circuit, overcurrent and over-temperature protection built in. The wide 96–264 V AC input range covers mains standards worldwide.

This listing bundles the adapter with three IoTCrazy heatsinks — self-adhesive pads for the SoC, RAM and USB controller that shed heat passively and hold off thermal throttling during long workloads.

Key Features

• Official Raspberry Pi supply — Made for the Raspberry Pi 4 Model B and Raspberry Pi 400
• 5.1 V / 3.0 A output — The slightly raised voltage offsets cable losses so the board sees a full 5 V
• Wide input range — 96–264 V AC
• Fully protected — Short circuit, overcurrent and over-temperature protection
• Captive USB-C cable — Nothing to lose, and no risk of an underrated cable spoiling the supply
• Three heatsinks included — Self-adhesive aluminium pads to keep the Pi cool under sustained load
