Working Principle

The power supply converts standard 100–240V AC mains power into a regulated 5.1V DC output suitable for powering the Raspberry Pi 4 Model B.

The regulated output is designed to maintain stable voltage during normal operation and when the Raspberry Pi is powering connected peripherals such as USB devices, storage drives, HATs, and other accessories.

The integrated protection circuitry helps protect the power adapter and connected hardware during abnormal conditions such as excessive current, short circuits, or overheating.

Stable Power for Raspberry Pi 4

The Raspberry Pi 4 can require more power than earlier Raspberry Pi models, especially when the processor is under heavy load or when multiple peripherals are connected.

The 5.1V 3A output provides sufficient power for many typical Raspberry Pi 4 applications, helping support stable operation and reduce the likelihood of power-related interruptions.

Using an appropriate power supply is particularly important for applications that use USB storage, displays, cameras, networking equipment, HATs, or other power-demanding peripherals.

Protection Features

The power supply includes built-in safety protections:

• Short-Circuit Protection: Helps protect against output short circuits.
• Overcurrent Protection: Helps prevent excessive current from damaging the adapter.
• Overtemperature Protection: Helps protect the power supply during excessive thermal conditions.
