GeeekPi 18W 5V 3.6A Power Supply for Raspberry… vs Geekworm P173 Heavy Duty Passive Cooling… — Head-to-Head (2026)

Our verdict

GeeekPi 18W 5V 3.6A Power Supply for Raspberry… is our pick.

If you can only buy one, buy the GeeekPi 18W supply. A Raspberry Pi 4 will not boot reliably without a compliant 5V rail, and this one delivers 3.6A (18W) against the official brick's 3A/15.3W. The Geekworm P173 is a 174-gram thermal upgrade to a board that already runs without it. These are complements, not rivals: the sensible move in 2026 is to buy both, in that order, since together they cost little.

Buy the GeeekPi 18W 5V 3.6A supply if you are powering a Pi 4, Orange Pi 5/5B, or an older micro-USB Pi and need guaranteed headroom for USB-SSD boot, an NVMe HAT, or a powered camera. It also adds an inline ON/OFF switch, so you stop yanking the plug and corrupting SD cards. Buy the Geekworm P173 Heavy Duty case if your Pi 4 Model B is already powered properly but is thermal-throttling under sustained load. Its 174 g fully passive aluminum enclosure with 4 heatsink pillars gives you silent, fanless, dust-tolerant 24/7 operation at a budget price.
