AI Verdict
This 27-watt USB-C power supply delivers 5.1V/5A for Raspberry Pi 5, but its 120mm cable severely limits placement options.
This power supply is a situational fit because it meets the 27-watt, 5.1V/5A power requirements for the Raspberry Pi 5, but its extremely short 120mm cable severely limits where you can place your device. It's only practical if your Pi is right next to a power source.
If you need more than 5 inches of cable reach, look for a power supply with a detachable USB-C cable or one explicitly stating a cable length of 1.5 meters or more.

Dimension Scores
Delivers the specified 27 watts with 5.1V/5A output and multiple PD profiles, which is crucial for Raspberry Pi 5 performance.
As a power adapter, it operates silently with no moving parts.
Without specific user feedback, it's assumed to be average for a budget power supply, offering standard multi-protection features.
The fixed 120mm cable offers no practical cable management options and severely restricts placement.
Best For
- Raspberry Pi 5 users needing 27W power in extremely close proximity to an outlet.
- Bench testing Raspberry Pi 4 or 5 where the power supply can sit directly next to the board.
- Powering compatible KVM-A3/A8 or X-series boards with minimal cable reach.
Not Recommended For
- Any Raspberry Pi setup requiring the power supply to be more than 5 inches from the board.
- Users who need flexible placement of their Raspberry Pi relative to a power outlet.
- Installations where the power supply needs to be hidden or routed away from the device.
Watch Out For
- The 120mm (4.72-inch) cable length means your Raspberry Pi must be positioned within inches of the power outlet.
- No user feedback available to confirm if the 27W output is consistently maintained under sustained high load.
- The fixed USB-C cable means if the cable is damaged, the entire power supply needs replacement.

What Buyers Say
This Geekworm 27W USB-C power supply is designed to meet the specific power needs of the Raspberry Pi 5, providing 5.1V at 5A. While it boasts Power Delivery support and multiple protection features, the most striking aspect is its incredibly short 120mm integrated cable. This length means your Raspberry Pi must sit almost directly on top of or immediately adjacent to the power outlet. There's no specific user feedback available to detail common complaints or praises beyond the general product specifications, so long-term performance or specific quirks are unknown.
“Seriously, who makes a power cable this short? My Pi has to practically sit on the wall outlet, it's ridiculous for any actual setup.”
Common Praise
- Provides the correct 5.1V/5A power output for Raspberry Pi 5.
- Supports Power Delivery (PD) technology for efficient power delivery.
- Includes over voltage, over current, and short circuit protection.
- Compatible with Raspberry Pi 4 and various Geekworm KVM/X-series boards.
Common Complaints
- The integrated USB-C cable is extremely short at 120mm (4.72 inches).
- No specific user reports on durability or performance under continuous heavy load.
- Only comes with a US plug, limiting international use without an adapter.
- Lack of specific user reviews makes it hard to gauge real-world issues.
Ownership Tips
- The short cable means you'll definitely need an extension cord for the wall outlet if your Pi isn't right next to it.
- The adapter itself feels like a standard budget power brick, not overly heavy or light.
- The USB-C connector fits snugly into the Raspberry Pi 5, no wobbling reported.
- Without a detachable cable, if the cable frays or breaks, the whole unit is trash.

Buying Guide
When you're buying a power supply for something like a Raspberry Pi 5, you need to make sure it can actually deliver enough juice. The Pi 5 is power-hungry, especially if you're plugging in USB devices. Skimping here can lead to 'under-voltage' warnings and unstable performance. Also, the cable length is a huge deal for where you can even put your project.
Wattage (27W)
This is the total power the adapter can provide. For the Raspberry Pi 5, 27W is the recommended minimum to ensure stable operation, especially when using peripherals. Think of it like the engine size in a car – more watts means more potential power.
Voltage (5.1V) and Amperage (5A)
These are the specific electrical characteristics. The Raspberry Pi 5 needs 5.1 volts at 5 amps. If the voltage is too low, your Pi won't run right; if the amperage isn't enough, it can't draw the power it needs. It's like making sure the gas pump delivers the right type and amount of fuel for your car.
USB-C Connector with Power Delivery (PD)
USB-C is the physical connection, and PD means the power supply can intelligently negotiate different power levels with your device. This is important for the Pi 5 to get its full 27W, as older USB-C chargers might not provide enough power even if they fit.
Cable Length (120mm)
This is how far your Raspberry Pi can be from the wall outlet. A 120mm cable is extremely short, meaning your Pi will need to be almost directly next to the power source. This is a critical factor for planning your setup.
Alternatives
If this power supply's 120mm cable is too short, look for adapters with a detachable USB-C cable or a fixed cable length of at least 1.5 meters (about 5 feet) to allow for more flexible placement.
