Pros
- Provides the exact 5.1V/5A output required for stable Raspberry Pi 5 operation, preventing undervoltage issues.
- Utilizes GaN technology, allowing for a smaller form factor and cooler, more stable operation compared to traditional power bricks.
- Includes an integrated LED indicator power switch, designed to minimize voltage drop for consistent performance.
- Offers comprehensive protection against over voltage, over current, and short circuits, enhancing device safety.
- Supports multiple output profiles (5.1V/5A, 9V/3A, 12V/2.25A, 15V/1.8A) for broader compatibility with PD devices.
Cons
- The cable length is a fixed 120mm (approximately 4.7 inches), which might be too short for some setups, limiting placement flexibility.
- While ETL Listed, the absence of other specific certifications beyond general protection features isn't detailed.
- No specific data on standby power consumption is provided, which could be a minor concern for always-on devices.
Dimension Scores
It delivers the precise 5.1V/5A required by the Raspberry Pi 5 and uses GaN technology for efficient, cool operation.
As a GaN power supply, it operates silently without any moving parts or fans, ensuring a quiet environment.
It is ETL Listed and includes multiple protection features, indicating adherence to safety and quality standards.
The fixed 120mm cable is quite short, which can limit placement options and potentially lead to cable clutter if extensions are needed.
Best For
- Powering a Raspberry Pi 5 2GB/4GB/8GB/16GB in a compact setup where space is limited.
- Users needing a dedicated power supply that guarantees the 5.1V/5A requirement for Raspberry Pi 5.
- Environments requiring a power supply with an integrated, low-voltage-drop power switch.
Not Recommended For
- Setups requiring a longer power cable than 120mm without an extension.
- Users seeking a multi-port power adapter for simultaneously charging other devices beyond the Pi 5's needs.
Watch Out For
- The 120mm cable length is quite short, potentially forcing the Raspberry Pi 5 to be very close to the power outlet or requiring an extension cord.
- Despite being ETL Listed, specific details on surge protection ratings or other advanced safety features are not provided.
- No user reviews were available at the time of this assessment, so long-term durability or common failure points are unknown.
