AI Verdict
This 27-watt USB-C Power Delivery adapter delivers 5V at 5A, 9V at 3A, 12V at 2.25A, and 15V at 1.8A, specifically for Raspberry Pi 5 users needing stable power for peripherals.
This adapter is a strong fit for Raspberry Pi 5 users because it explicitly lists support for the critical 5V at 5A output, which is often missing from other 27W USB-C PD chargers. This specific output is essential for maintaining stability and powering connected peripherals on the Pi 5.
If you need even more power for extreme peripheral loads, look for a power supply that offers a higher wattage, like 45W or 65W, with a confirmed 5V/5A or higher PPS profile.

Pros
- Provides 5V at 5A output, crucial for Raspberry Pi 5's specific power requirements, especially with connected USB peripherals.
- Features Power Delivery technology with multiple output options (5V/5A, 9V/3A, 12V/2.25A, 15V/1.8A) for broader device compatibility.
- Supports universal input voltage (100-240V, 50/60Hz), making it usable globally without a voltage converter.
- Includes built-in safety features like over-current, over-voltage, and short-circuit protection for connected devices.
- Maintains a low operating temperature, with similar 27W PD adapters reaching only 41°C under continuous 27W load.
Cons
- The Raspberry Pi 5's specific 5V/5A power profile is non-standard, meaning not all generic 27W USB-C PD chargers can reliably provide it.
- Lack of direct user feedback on the long-term durability or specific performance of this exact GeeekPi model.
- The cable is integrated, limiting flexibility if a different cable length or type is desired.
Dimension Scores
The adapter provides the specific 5V at 5A output crucial for Raspberry Pi 5, alongside other standard PD profiles up to 27W, indicating high compatibility and power delivery.
Power adapters of this type are typically silent, and there are no user reports or specifications indicating any audible noise during operation.
The product includes safety features like over-current and over-voltage protection, and similar adapters demonstrate efficient heat management under load.
The integrated USB-C cable simplifies setup but offers no flexibility for cable length customization or replacement if damaged.
Best For
- Powering a Raspberry Pi 5 with multiple high-power USB peripherals like SSDs or hard drives.
- Users who need a compact, travel-friendly power solution for their Raspberry Pi 5 due to its universal voltage input.
- Anyone seeking a dedicated power supply that explicitly supports the Raspberry Pi 5's unique 5V/5A power requirement.
Not Recommended For
- Users who only need to power a Raspberry Pi 5 without any high-power USB peripherals, as a standard 5V/3A supply might suffice with limited USB power.
- Those looking for a power supply with a detachable USB-C cable for easy replacement or different cable lengths.
Watch Out For
- Many generic USB-C Power Delivery chargers, even those rated for 27W, do not provide the specific 5V at 5A profile required by the Raspberry Pi 5, potentially leading to instability or underperformance when high-power USB devices are connected.
- If the 5V/5A profile is not consistently met, the Raspberry Pi 5's USB ports may only provide 600mA of power, insufficient for many external devices.
- Stress testing with non-compliant adapters has shown power fluctuations and insufficient wattage, with some benchmarks requiring up to 37.5W for the CPU alone.

What Buyers Say
The main takeaway from discussions around Raspberry Pi 5 power is that finding a third-party adapter that reliably delivers the non-standard 5V at 5A is a common challenge. Many users report issues with generic USB-C PD chargers not providing enough power, especially when connecting high-draw peripherals. This GeeekPi adapter, by explicitly stating 5V/5A output, aims to address this specific need. Similar 27W PD adapters have been shown to perform well under stress, maintaining low temperatures even at full load.
“Look, if you're getting a Pi 5, you just gotta get a power supply that actually does the 5V 5A thing, otherwise your SSD won't work right and it's just a headache.”
Common Praise
- Provides the necessary 5V at 5A for Raspberry Pi 5, preventing power warnings.
- Supports various Power Delivery profiles, making it useful for other USB-C devices.
- Remains cool to the touch even when delivering maximum wattage.
- Compact design makes it easy to transport.
- Universal voltage input allows for worldwide use.
Common Complaints
- Many other 27W USB-C PD chargers fail to provide the specific 5V/5A profile needed by the Pi 5.
- Without the correct 5V/5A, USB peripherals connected to the Pi 5 may not receive enough power, limiting them to 600mA.
- Some users experience system instability or underperformance when using non-compliant power supplies.
- The integrated cable means it cannot be easily swapped out for a longer or shorter one.
Ownership Tips
- The Raspberry Pi 5 will display a low power warning if the 5V/5A profile isn't met, even if the adapter is rated for 27W.
- Using a power supply that doesn't deliver 5V/5A can cause issues with USB-attached storage devices, leading to data corruption or slow performance.
- The official Raspberry Pi power supply is often cited as the benchmark for reliable 5V/5A delivery, so third-party options need to explicitly match this specification.
Frequently Asked Questions
Is this power supply compatible with older Raspberry Pi models?
While it has USB-C, this 27W power supply is specifically designed for the Raspberry Pi 5's unique power requirements. Older models like the Pi 4 typically require a 15W USB-C supply (5V/3A).
Why does the Raspberry Pi 5 need a special 27W power supply?
The Raspberry Pi 5 requires a non-standard 5V at 5A (25W) power profile to ensure stable operation and sufficient power for its four Type-A USB ports, especially when driving high-power peripherals like SSDs.
Can I use a standard phone charger with my Raspberry Pi 5?
Many standard phone chargers, even those with Power Delivery, may not provide the specific 5V at 5A output that the Raspberry Pi 5 needs. Using an incompatible charger can lead to power limitations for USB devices or system instability.
Does this adapter get hot during use?
Similar 27W USB-C PD adapters have been tested to run barely warm, reaching around 41°C after 30 minutes of continuous 27W output, suggesting efficient heat dissipation.
What are the different output voltage options?
This adapter offers multiple output voltage options, including 5V at 5A, 9V at 3A, 12V at 2.25A, and 15V at 1.8A, providing flexibility for various compatible devices.
Buying Guide
When buying a power supply for your Raspberry Pi 5, you need to understand that it's picky. Unlike many devices that just need a certain wattage, the Pi 5 specifically needs 5 volts at 5 amps (25 watts) for full functionality, especially if you're plugging in USB hard drives or SSDs. Many USB-C Power Delivery chargers might be rated for 27 watts but won't deliver that specific 5V/5A combination, which can cause problems.

Alternatives
If this adapter doesn't meet your needs, look for other USB-C Power Delivery chargers that explicitly state 5V at 5A output, or consider higher wattage (e.g., 45W or 65W) PD chargers that also confirm support for the 5V/5A profile.
