Specifications

Why Choose the Official Raspberry Pi 4 Power Adapter?

• Eliminates Under-Voltage Throttling: The 5.1V/3A output provides a slight over-voltage margin that compensates for cable drop, so you never see the dreaded lightning-bolt warning icon on your Pi 4.
• Designed by the Raspberry Pi Foundation: Unlike generic USB-C chargers, this PSU is engineered specifically for the Pi 4's power delivery requirements - no negotiation issues, no compatibility headaches.
• Clean, Regulated Power: Low ripple and noise output protects sensitive GPIO peripherals, cameras, and HATs from power-related glitches.
• Universal AC Input (96-264V): Works seamlessly across Indian voltage standards and internationally - ideal for portable setups or travel.
• Short-Circuit & Over-Current Protection: Built-in safety features protect both the adapter and your Raspberry Pi from electrical faults.
• 100% Authentic - Guaranteed: Sourced directly from authorized Raspberry Pi distributors. Every unit is verified genuine before dispatch.
• Fast Shipping from Bengaluru: 1-5 day shipping, 7-8 day delivery across India; same-day dispatch available for Bengaluru orders.
• Expert Support Included: Our engineers can help you troubleshoot power issues, recommend complementary accessories, and assist with project planning.

Why Not Just Use a Phone Charger?

This is one of the most common questions we hear - and the answer matters. Most USB-C phone chargers output 5.0V and rely on USB Power Delivery negotiation to increase voltage for fast charging. The Raspberry Pi 4, however, does not support USB-PD negotiation. It expects a fixed 5V supply capable of delivering at least 3A continuously. A standard phone charger typically provides only 2A at 5V before switching to a higher voltage the Pi cannot use, leading to:

• Frequent under-voltage warnings ( lightning bolt icon)
• CPU throttling that slows performance by up to 50%
• Random crashes during high-load tasks like video playback or compilation
• USB peripheral disconnections and SD card corruption

The official adapter solves all of these problems by delivering a rock-steady 5.1V at 3A with no negotiation required - exactly what the Pi 4 was designed to receive.

Detailed Feature Breakdown

Stable 5.1V Output - The Key Difference

The 0.1V over-voltage design is intentional. Voltage drops across the USB-C cable and connector can reduce the effective voltage reaching the Pi's SoC by 0.1-0.2V. By starting at 5.1V, the official adapter ensures the Broadcom BCM2711 processor always receives voltage within its optimal operating range, even under full 3A load with peripherals attached.

3A Continuous Current

The Raspberry Pi 4 itself draws approximately 1.2A at idle and up to 2.5A under heavy CPU/GPU load. The remaining current headroom supports USB-connected peripherals such as keyboards, mice, external drives, and USB-powered HATs - all without exceeding the adapter's rating.

Built-In Safety Protections

The adapter includes over-voltage protection (OVP), over-current protection (OCP), short-circuit protection (SCP), and thermal shutdown. These features ensure that a wiring mistake or peripheral fault won't damage your Raspberry Pi or create a fire hazard.
