Raspberry Pi 5 Power Adapter 5A Type-C 27W Original UK
Price in Sri Lanka

The Official Raspberry Pi 27W USB-C Power Supply is a high-quality, reliable power adapter specifically designed for the Raspberry Pi 5. While it shares the USB-C standard with smartphone chargers, it is uniquely engineered to deliver a consistent 5.1V at 5A. This ensures that the Pi 5 can power high-drain peripherals, such as NVMe SSDs or dual 4K displays without triggering undervoltage warnings.

Specifications

• Output Power: 27W (Maximum)
• Voltage/Current (PD Modes):
  • 5.1V / 5.0A (Standard Pi 5 Power)
  • 9.0V / 3.0A
  • 12.0V / 2.25A
  • 15.0V / 1.8A
• Input Voltage: AC 100V – 240V (50/60Hz)
• Connector: USB-C
• Cable Length: 1.2m (18 AWG)
• Efficiency: Level VI efficiency rating

Features

• High-Current 5.1V / 5A Mode: Specifically tuned to meet the peak power requirements of the Raspberry Pi 5. Standard USB-C Power Delivery (PD) supplies typically drop to 3A at 5V; this official unit maintains 5A, providing the necessary headroom for USB-attached devices.
• Universal Compatibility: Beyond the Pi 5, it functions as a standard PD power supply for Raspberry Pi 4, tablets, and smartphones, automatically negotiating the correct voltage for the connected device.
• Robust Protection: Built-in safeguards against short circuits, over-current, and over-temperature to ensure the safety of both the power supply and the connected hardware.
• Superior Build Quality: Features thick 18 AWG copper cabling to minimize voltage drop over the length of the 1.2m cable, a common issue with generic chargers.

Why use the 27W supply?

While the Raspberry Pi 5 will boot with a standard 15W (5V/3A) supply, the firmware will automatically limit the total current drawn by the four USB ports to 600mA. Using this official 27W supply unlocks the full 1.6A current limit for the USB ports, which is essential for:

• Running high-speed external SSDs.
• Powering multiple bus-powered USB peripherals.
• Stable overclocking of the BCM2712 processor.
