Official Raspberry Pi 4 USB-C Power Supply 5.1V 3A (15.3W) – EU Plug

Official Raspberry Pi 4 USB-C Power Supply 5.1V 3A (15.3W) – EU Plug is the genuine Raspberry Pi Foundation 15.3W AC-to-DC USB Type-C power adapter engineered specifically to meet the peak current demands of the Raspberry Pi 4 Model B single-board computer. Unlike standard 5.0V smartphone chargers that suffer voltage sag across thin cables—triggering the Raspberry Pi’s low-voltage lightning bolt throttling warning—this supply outputs a rock-solid 5.1V DC at up to 3.0A through a captive 1.5-meter 18 AWG low-resistance USB-C cable.

Key Features:

• 5.1V 3.0A (15.3W) Precision Output: Engineered with a +0.1V line-drop margin (5.1V) so the Raspberry Pi 4 receives a full 5.0V rail even under 3A peak CPU and USB peripheral loads.
• Captive 1.5m 18 AWG Thick-Gauge Cable: Permanently attached heavy-gauge 18 AWG wire eliminates contact resistance and voltage drop common in detachable USB-C cables.
• Full Safety & Protection Suite: Built-in short-circuit, overcurrent, and overtemperature protection with DoE Level VI energy efficiency compliance.
• High 50,000-Hour MTBF Reliability: Designed for 24/7 continuous industrial, server, and home-automation operation.
• 2-Pin Europlug (Type-C) AC Prongs: Directly compatible with standard Indian and European 230V AC wall sockets.
