Raspberry Pi 4 Power Supply - USB-C 5.1V 15.3W
Raspberry Pi 4 Power Supply - USB-C 5.1V 15.3W
Official Raspberry Pi 4 USB-C Power Supply (5.1V 3A / 15.3W)
Keep your Raspberry Pi 4 Model B running at peak performance without fear of undervoltage warnings, throttling, or unexpected reboots. Beyond the Pi, it is also an ideal, rock-solid power source for maker electronics, home automation gear, ESP32 boards, RFXtrx/RFXcom modules, and any sensitive 5V USB-C hardware that suffers when powered by cheap phone chargers.
Most standard USB chargers drop below 5V under load, triggering erratic resets in microcontrollers and single-board computers. Engineered to sit steadily at 5.1V, this supply compensates for cable resistance to ensure stable, ripple-free power under heavy computational and wireless transmission spikes.
Available in classic Black and clean White to match your project enclosure or desk setup.
