iUniker 27W PD USB-C Power Supply for Raspberry Pi vs iUniker 5V 4A USB-C Power Supply for Raspberry Pi

Overview

The iUniker 27W PD USB-C Power Supply for Raspberry Pi 5 and the iUniker 5V 4A USB-C Power Supply for Raspberry Pi 4 are both designed to power Raspberry Pi devices, but they cater to different models and power needs. The former is specifically tailored for the Raspberry Pi 5, while the latter is optimized for the Raspberry Pi 4.

The iUniker 27W power supply is priced at $10.99, making it about 10% more expensive than the iUniker 5V power supply, which retails for $9.99. This difference in price reflects their differing capabilities and intended applications.

Power Output

The iUniker 27W PD USB-C Power Supply for Raspberry Pi 5 offers a higher power output compared to the iUniker 5V 4A USB-C Power Supply for Raspberry Pi 4. It delivers multiple output options: 5.1V at 5A, 9V at 3A, 12V at 2.25A, and 15V at 1.8A, making it versatile for various applications.

In contrast, the iUniker 5V 4A power supply provides a stable output of 5V at 4A, which is sufficient for Raspberry Pi 4 models but may not meet the higher demands of the Raspberry Pi 5. Thus, if you're using a Raspberry Pi 5, the iUniker 27W is the better choice for optimal performance and versatility.

Technology

The iUniker 27W PD USB-C Power Supply utilizes GaN (Gallium Nitride) technology, which allows for a more compact design without sacrificing performance or stability. This technology also contributes to lower operating temperatures, enhancing the longevity of the power supply.

On the other hand, the iUniker 5V 4A power supply does not specify any advanced technology like GaN but is built to deliver reliable performance for Raspberry Pi 4. For users prioritizing cutting-edge technology, the GaN-powered iUniker 27W represents a significant advancement.

Design and Usability

In terms of design, the iUniker 27W power supply is compact and efficient, making it easy to integrate into various setups without taking up excessive space. Its USB-C connector ensures compatibility with modern devices, and it includes a 120mm 18AWG cable.

The iUniker 5V 4A power supply features a convenient built-in ON/OFF switch, allowing users to easily power their devices on and off without unplugging. This can be particularly useful for frequent use in projects or educational environments, although it comes with a 5ft cable, providing flexibility in device placement. While both products offer ease of use, the switch feature of the iUniker 5V 4A gives it an edge in convenience for certain applications.

Safety Features

Safety is a crucial consideration when selecting a power supply. The iUniker 27W PD USB-C Power Supply is ETL listed, ensuring it meets rigorous safety standards. It also includes protections against over-voltage, over-current, and short circuits, providing peace of mind during operation.

The iUniker 5V 4A power supply is UL listed, which also indicates compliance with strict safety regulations, and it shares similar protective features. Both products are designed to operate safely within their specifications, making either a reliable choice in terms of safety. The choice may come down to personal preference regarding brand safety certifications.

Compatibility

The iUniker 27W PD USB-C Power Supply is specifically designed for the Raspberry Pi 5, making it an ideal choice for users of that model. It is compatible with both the 4GB and 8GB versions of the Raspberry Pi 5, ensuring it can cater to various user needs.

Conversely, the iUniker 5V 4A power supply is optimized for Raspberry Pi 4, supporting all its variants (1GB, 2GB, 4GB, and 8GB) as well as other devices like the Orange Pi 5/5B. If you own a Raspberry Pi 4 or similar device, the iUniker 5V power supply would be the more appropriate option, but it is not suitable for powering the Raspberry Pi 5 due to its lower power output.

Cable Length

Cable length can significantly impact usability and flexibility in device placement. The iUniker 5V 4A power supply features a generous 5ft long cable, which is advantageous for projects or setups where the power source is not in close proximity to the device.

In contrast, the iUniker 27W power supply comes with a shorter 120mm cable. While this may be sufficient for many desktop setups, some users may find the shorter cable less convenient, especially in larger spaces. For users who prioritize flexibility in their setups, the longer cable of the iUniker 5V 4A could be a decisive factor.

Which should you buy?

Choosing between the iUniker 27W PD USB-C Power Supply for Raspberry Pi 5 and the iUniker 5V 4A USB-C Power Supply for Raspberry Pi 4 ultimately depends on your specific needs. If you own a Raspberry Pi 5 and require a higher power output, the iUniker 27W is the clear winner, offering versatility and advanced technology. However, if you are using a Raspberry Pi 4, the iUniker 5V 4A power supply is perfectly suited for your needs, especially with its convenient ON/OFF switch and longer cable.

Both products have their merits, but your choice should align with the model of Raspberry Pi you own and the specific features you value most.
