Smraza 5.1V 3A Power Supply Compatible with… vs GeeekPi 27W Power Supply for Raspberry Pi 5 — Head-to-Head (2026)

Our verdict first, then the specs side by side.

Our verdict

GeeekPi 27W Power Supply for Raspberry Pi 5 is our pick.

If you own a Raspberry Pi 5, buy the GeeekPi 27W — its 5.1V/5A PD output is the only way to unlock the Pi 5's full power budget, while the Smraza's 5.1V/3A (15.3W) tops out at the Pi 4 spec and will trip undervoltage warnings on a Pi 5.

Buy the Smraza 5.1V 3A if you own a Raspberry Pi 4 (or Pi 3/3B+) and want a metal-shell, ETL-listed supply with a physical on/off switch. Buy the GeeekPi 27W if you own a Raspberry Pi 5 and need the full 5.1V/5A PD output to run NVMe HATs, the official active cooler, and USB peripherals without undervoltage throttling.
