Applications & Projects

• Raspberry Pi 5 Desktop: Powers the board + active cooler + keyboard/mouse + dual displays without throttling.
• NAS / File Server: Provides sufficient current to power USB-attached SSDs or NVMe drives via HATs.
• Edge AI Projects: Stable power for attached Coral USB Accelerators or Hailo modules.
• General PD Charging: Can also charge PD-enabled phones and tablets at up to 27W.

Project Evolution

• The Bottleneck: If you have been using a standard 15W USB-C Charger (like the Pi 4 supply), your Pi 5 is forced to limit downstream USB power to 600mA to prevent system crashes.
• The Upgrade: Connecting this 27W PD Supply tells the Pi firmware to unlock the full 1.6A USB current limit.
• What this enables: You can now boot directly from power-hungry NVMe SSDs or run multiple external hard drives without needing a powered USB hub.
• Effort Level: Plug-and-Play. No coding required; the hardware negotiation happens instantly on boot.

Virtual Technician & Safety Guide ⚠️

• Probots Lab Verified: We have tested this supply on our test bench. It maintains a solid 5.1V even under heavy processor load, preventing the "Lightning Bolt" undervoltage icon.
• Compatibility Note: While designed for Pi 5, this supply is backward compatible with Raspberry Pi 4 (it will run at 5.1V/3A).
• Cable Warning: The cable is captive (fixed) to the brick. This is a design feature to ensure the wire gauge is thick enough to carry 5A without voltage drop. Do not attempt to splice or extend this cable with low-quality USB extenders.

Package Includes:

• 1 x Raspberry Pi 27W USB-C Power Supply White, IN Plug

Frequently Asked Questions (FAQ)

• Why do I need 27W for a Raspberry Pi?
  The Pi 5 processor is more powerful, but the main reason is to provide extra headroom (up to 1.6A) for USB peripherals like SSDs.
• Will this work with Raspberry Pi 4 Model B?
  Yes, it will negotiate 5.1V @ 3A, which is perfect for the Pi 4.
• Does this supply come with a USB cable?
  Yes, it has a built-in (captive) 1.2m USB-C cable.
• Can I use a MacBook USB-C charger instead?
  Maybe, but many laptop chargers do not support the specific "5.1V @ 5A" profile, falling back to standard 5V/3A, which restricts USB peripheral power.
• What is the wire gauge of the cable?
  It uses high-quality 17AWG wire to minimize voltage drop over the 1.2m length.
• Does this plug fit standard Indian sockets?
  Yes, it comes with a standard 2-pin Indian plug (Type C compatible).
• Is this supply regulated?
  Yes, it is a switching mode power supply with tight voltage regulation.
• Can I power a Raspberry Pi 3 with this?
  No, the Pi 3 uses Micro-USB. You would need a USB-C to Micro-USB adapter (not recommended for high loads).
• Does it support Quick Charge (QC)?
  It uses USB Power Delivery (PD), which is the standard protocol. It does not explicitly support proprietary QC protocols.
• Why is the output 5.1V and not 5.0V?
  The slight boost compensates for voltage drop across the cable and PCB traces, ensuring the chip gets a full 5.0V.
• Can I charge my phone with this?
  Yes, if your phone supports USB-PD, it will charge effectively at up to 27W.
• Will this stop the undervoltage warning on my Pi 5?
  Yes, this is the definitive solution for undervoltage warnings on the Pi 5.
• Is the output voltage adjustable?
  No, the voltage is negotiated automatically by the device (PD); you cannot manually set it.
• Does it get hot during use?
  It gets warm, which is normal for a 27W adapter, but it should not be too hot to touch.
• Can I leave it plugged in 24/7?
  Yes, it is designed for continuous operation in server/desktop applications.
• What happens if I short the output?
  It has built-in short-circuit protection and will cut power to prevent damage.
• Do I need this if I don't use USB peripherals?
  A standard 15W supply might suffice for a "headless" Pi 5, but this 27W supply guarantees stability if your CPU spikes.
• Is this the white or black version?
  This specific SKU (SC1151) is the White version.
• Does it include an on/off switch?
  No, the supply is always on. The Pi 5 has a dedicated power button on the board itself.
• Is this compatible with the Raspberry Pi Active Cooler?
  Yes, it provides ample power to run the active cooler alongside the board.
