Why a Quality Power Supply Matters?

Using a generic phone charger for your development board is a common mistake. Single-board computers like the Raspberry Pi require precise voltage regulation. A subpar power supply can cause "under-voltage" warnings, SD card corruption, or random reboots. SunFounder’s Raspberry Pi power supply options are tested to deliver consistent 5.1V output even under heavy load, ensuring your Pi 5 or 4 operates at peak performance.

Choosing the Right Power Adapter

○ For Raspberry Pi 5: You need a 27W USB-C PD power supply (5V/5A) to support peripherals and PCIe devices fully.
○ For Raspberry Pi 4: A standard 15W USB-C power supply (5V/3A) is recommended for most desktop and media center applications.
○ For Arduino: Our 9V 1A DC adapters with a 5.5mm barrel jack are perfect for powering Arduino Uno and Mega boards externally.

Frequently Asked Questions

○ Can I use my laptop charger for Raspberry Pi 5?
While some USB-C laptop chargers work, they may not negotiate the specific 5V/5A profile required by the Pi 5. For the best stability, we recommend using a dedicated Raspberry Pi power supply designed for the board.
○ Does the power supply have an on/off switch?
Yes, many of our third-party Raspberry Pi power adapters feature an inline on/off switch, allowing you to power cycle your board conveniently without unplugging the cable.
○ What power supply do I need for a robot kit?
Robots often use high-current batteries (like 18650s) rather than wall adapters. However, for bench testing, a stable 5V/3A power supply connected to the controller is essential.
