Why Choose This?
- Official Raspberry Pi Foundation Approved: Engineered by Stontronics to meet the exact power requirements of the Pi 3B, preventing the dreaded lightning bolt under-voltage icon.
- 5.1V Output - Not Just 5V: The extra 0.1V compensates for voltage drop across the micro USB cable, ensuring your Pi receives a full 5V at the GPIO header.
- 2.5A Capacity: Provides enough headroom to power the Pi 3B along with USB peripherals such as keyboards, mice, and small USB drives without brownouts.
- Clean, Regulated Power: Low ripple design protects sensitive components and ensures stable operation during CPU-intensive tasks and overclocking.
- Built-in Safety: Over-current, over-voltage, and short-circuit protection safeguard both the adapter and your Raspberry Pi.
- Universal AC Input: Works on 100-240V mains, making it suitable across India and internationally.
- 100% Authentic: Sourced directly from authorized distributors - no counterfeit risk.
- 1-5 days shipping: Ships from our Bengaluru warehouse to most locations across India.
Project Ideas
- Home Media Centre: Power your Raspberry Pi 3B running Kodi or LibreELEC for a reliable, always-on streaming box without random shutdowns caused by inadequate power.
- Retro Gaming Console: Build a RetroPie station - the stable 2.5A supply ensures smooth gameplay even when emulating demanding consoles like the N64 or PSP.
- IoT & Home Automation Server: Run Home Assistant, Node-RED, or MQTT broker on your Pi 3B with confidence that the power supply won't cause SD card corruption during writes.
- Network-Attached Storage (NAS): Use your Pi with an external USB hard drive - the 2.5A output supports peripheral power draw alongside the board.
- Learning & Education: Ideal for students learning Linux, Python programming, or electronics - a dependable PSU means fewer frustrating troubleshooting sessions.
- Digital Signage & Kiosk: Deploy a Pi-powered display in shops or offices with a power supply rated for continuous, long-term operation.
- Pi-hole Ad Blocker: Set up a network-wide ad blocker that runs 24/7 - the efficient Stontronics adapter keeps power consumption and heat minimal.
What's in the Box
- 1 x Stontronics 5.1V, 2.5A Micro USB Power Adapter (White)
- Documentation and safety information
Frequently Asked Questions
Is this the official Raspberry Pi power supply?
Yes. Stontronics is the manufacturer licensed by the Raspberry Pi Foundation to produce the official power supply. This is the genuine, foundation-approved adapter - not a third-party clone.
Why 5.1V instead of 5V?
Every micro USB cable introduces a small voltage drop due to resistance. By outputting 5.1V at the adapter end, the voltage arriving at the Raspberry Pi's power input stays close to the ideal 5V, preventing under-voltage throttling.
Can I use this with a Raspberry Pi 4?
No. The Raspberry Pi
