iUniker GaN PD 27W 5.1V 5A 27W PD Power Supply USB-C for Raspberry Pi 5 vs 24V / 12V to 5V 5A Power Buck Converter DC-DC Power Down Module Power Supply Boa

Price Comparison

When it comes to pricing, the iUniker GaN PD 27W power supply is significantly more expensive than the 24V / 12V to 5V power buck converter. The iUniker is priced at £13.79, while the buck converter costs just £7.69. This price difference of £6.10 could make the buck converter a more attractive option for budget-conscious buyers. However, the higher price of the iUniker may be justified by its advanced features and compatibility with the Raspberry Pi 5.

Compatibility

The compatibility of each product varies significantly, impacting their suitability for different applications. The iUniker is specifically designed for use with the Raspberry Pi 5, making it an ideal choice for Raspberry Pi enthusiasts and developers. In contrast, the 24V / 12V to 5V buck converter is more versatile, capable of powering a range of devices including iPhones, iPads, and other smartphones. This broad compatibility could make the buck converter a more appealing option for users with diverse charging needs.

Technology and Efficiency

The iUniker GaN PD power supply utilises GaN technology, which allows for a compact design without sacrificing performance. This technology contributes to lower operating temperatures and enhanced stability, making it suitable for prolonged use. On the other hand, the buck converter employs a synchronous rectification scheme, offering high efficiency for a wide voltage range. This efficiency ensures reliable performance, particularly when fast charging various devices. Users looking for cutting-edge technology may favour the iUniker, while those prioritising efficiency might prefer the buck converter.

Output Specifications

In terms of output specifications, the iUniker provides a range of voltage options including 5.1V at 5A, 9V at 3A, 12V at 2.25A, and 15V at 1.8A. This variety enables it to cater to different requirements, especially for Raspberry Pi projects. Conversely, the buck converter delivers a consistent 5V at 5A output from either 24V or 12V sources. This straightforward output is ideal for powering devices that require a stable 5V supply. Users with specific voltage needs might find the iUniker more suitable, whereas those needing a standard 5V output could lean towards the buck converter.

Protection Features

Both products feature protective capabilities, but they differ in their implementations. The iUniker power supply includes over-voltage, over-current, and short-circuit protection, which enhances safety during use. This level of protection is vital for sensitive electronics like the Raspberry Pi. In contrast, the buck converter comes with an independent anti-static package, ensuring its safety during transportation and storage rather than during operation. While both products offer protection, the iUniker's focus on operational safety may provide added peace of mind for users working with delicate devices.

Design and Portability

Portability is a key aspect for many users when selecting a power supply. The iUniker, being a GaN power supply, is designed to be smaller and more compact without compromising power output. However, its specific application for the Raspberry Pi may limit its versatility. The buck converter, measuring just 63 × 27 × 10mm and weighing only 22g, is designed for easy transport and integration into various applications. This lightweight and compact design makes it an excellent choice for users who often move their devices or require a power solution on the go.

User Experience

User experience can greatly influence the choice between these two products. The iUniker is straightforward to use, especially for Raspberry Pi users, as it includes a UK plug and a 120mm cable. Its compatibility with multiple output voltages also allows for flexibility in usage. Conversely, the 24V / 12V to 5V buck converter provides a USB port, DC plug, and connecting terminals, making it adaptable for different devices and user scenarios. Users may find the iUniker more user-friendly for specific Raspberry Pi applications, while the buck converter offers versatility for various charging needs.

Which should you buy?

The decision between the iUniker GaN PD 27W power supply and the 24V / 12V to 5V buck converter ultimately hinges on individual requirements. If you are primarily seeking a power supply for the Raspberry Pi 5 with advanced features and protection, the iUniker at £13.79 is a strong choice. However, if budget is a significant concern and you require a versatile power solution for various devices, the 24V / 12V to 5V buck converter at £7.69 offers excellent value and efficiency. Assess your specific needs to determine which product aligns best with your usage scenario.
