Power Supply for Raspberry Pi Boards

This 5 V 3 A adapter is built for Raspberry Pi 3 B+, Pi 2 B, Pi Zero and Model A, A+, B, B+ boards. It delivers stable DC power through a fixed Micro-USB plug. The unit accepts 100 V to 240 V input at 50 Hz or 60 Hz, making it suitable for worldwide mains voltages.

Safety Protection Built In

The supply includes short-circuit, over-current, over-voltage and over-temperature safeguards that cut power automatically during a fault. These protections prevent damage to the connected board and reduce the risk of component failure during prolonged use. No extra software or configuration is required.

Fixed Cable and Connector

A 3.3 ft (100 cm) Micro-USB cable is permanently attached, so there is no separate lead to lose or misplace. The length allows the board to sit on a bench or inside a case while the adapter reaches a wall socket or power strip. The connector fits only boards with a Micro-USB power port.

Questions about this item

Will the Micro-USB plug or the 3.3ft cable need replacing before the power supply itself fails?

The Micro-USB connector and 3.3ft cable are fixed to the unit; they cannot be swapped separately. If the plug wears or the cable frays, the whole adapter must be replaced.

Which protection limit activates first during continuous 3A load — over-current or over-temperature?

Built-in safeguards include short-circuit, over-current, over-voltage and over-temperature protection. The adapter will trip whichever threshold is reached first under sustained load.

How warm does the brick get and is there any fan noise when it runs 24/7 at 5V 3A?

The unit has no fan, so it runs silently. Heat rises until the over-temperature protection engages, but no surface-temperature figure is published.
