Key Applications & Projects

• Home Media Centres: Runs the Pi 5 at full speed for 4K streaming without throttling.

• Edge AI & Computer Vision: Provides stable current for AI hats and camera modules.

• Network Attached Storage (NAS): Essential when powering external NVMe or SSD drives directly from the Pi's USB ports.

• General Purpose PD Charging: Capable of charging PD-enabled mobile phones and tablets efficiently.

Project Evolution

• The Bottleneck: If you are coming from a Raspberry Pi 4, your old 15W (5.1V/3A) supply is now a bottleneck. It physically cannot provide the current needed for the Pi 5's PCIe lane and boosted USB ports.

• The Upgrade: This 27W supply acts as a "Key" that unlocks the Pi 5's firmware limit, automatically boosting the USB peripheral current limit from 600mA to 1.6A. This allows you to attach power-hungry hard drives without a powered hub.

• Effort Level: Beginner. It is a strictly plug-and-play solution. The Probots™ Lab Verified ???? guarantee ensures the PD handshake happens instantly on boot.

Virtual Technician & Safety Guide

• ⚠️ Voltage Warning: While this supply supports standard PD voltages (9V/12V/15V), the Raspberry Pi 5 only uses the 5V rail. The higher voltages are strictly for other PD-compatible devices.

• Wiring/Cable: The cable is captive (permanently attached). Do not attempt to extend it with low-quality USB-C extensions, as this will cause a voltage drop and trigger under-voltage warnings.

• Heat Dissipation: Under full 27W load, the brick will get warm. This is normal operation. Ensure it is placed in a ventilated area.

Accessories & Compatibility

• Included: 1x Official 27W USB-C Power Supply (Black).

• Required (Sold Separately): Raspberry Pi 5 Board.

• Related: Active Cooler for Raspberry Pi 5 (Recommended for high-load use).

Frequently Asked Questions (FAQ)

• Why does the Raspberry Pi 5 need a 27W power supply?
  The Pi 5 consumes more power than previous models and requires 5A at 5.1V to enable full current (1.6A) for USB peripherals like SSDs.
• Can I use my old Raspberry Pi 4 power supply with the Pi 5?
  Yes, but the Pi 5 will detect the lower capability and limit USB current to 600mA. You may also see under-voltage warnings under load.
• Will this power supply work with my mobile phone?
  Yes, it supports standard USB-PD profiles (9V/3A, 12V/2.25A, 15V/1.8A), making it a fast charger for many modern phones.
• Is this the official Raspberry Pi product?
  Yes, this is the official accessory manufactured by the Raspberry Pi Foundation, ensuring full compatibility.
• Does this power supply come with a USB cable?
  Yes, it features a 1.2-meter captive (permanently attached) USB-C cable designed to handle 5A current.
• Why is the output voltage 5.1V instead of 5V?
  The 5.1V output compensates for voltage drop across the cable, ensuring exactly 5V reaches the board's PMIC.
• Can I use this power supply with a Raspberry Pi 4?
  Yes, it is backward compatible and will safely power a Raspberry Pi 4.
• Does this support Qualcomm Quick Charge (QC)?
  No, this supply uses the USB Power Delivery (PD) standard, not proprietary standards like QC.
• What is the maximum current this supply can deliver at 5V?
  It delivers a maximum of 5 Amps at 5.1 Volts.
• Can this power a laptop?
  It can charge some efficient USB-C laptops slowly (if they accept 27W PD), but it is not designed for high-power laptops.
• Does it have short-circuit protection?
  Yes, the official supply includes over-current and short-circuit protection features.
• Why do I need a specific 5A cable?
  Standard USB-C cables are often rated for only 3A. Pushing 5A through them is dangerous; this unit's integrated cable is rated for the full load.
• Will this fix the "Low Voltage Warning" on my screen?
  Yes, if your current supply is insufficient, switching to this official 27W supply will eliminate those warnings.
• Is the AC plug removable?
  No, this version comes with a fixed plug standard for Indian sockets (Type D/Generic 2-pin compatible).
• Can I use this to power a Jetson Nano 2GB?
  If the Jetson Nano accepts 5V/3A via USB-C, this supply can easily handle that requirement.
• What is the efficiency rating of this power supply?
  It meets Level VI energy efficiency standards, minimizing wasted power when idle.
