Power Output

The power output of a power supply directly influences its performance in different applications. The 27W PD USB C GaN Power Supply delivers a maximum output of 27W, which is ample for powering devices like the Raspberry Pi 5 effectively.

In contrast, the MEAN WELL LRS-100-24 provides a significantly higher power output of 108W at 24V and 4.5A. This makes it ideal for powering larger systems or multiple devices simultaneously. For users requiring more robust power capabilities, the MEAN WELL supply's output is a clear advantage.

Efficiency

Efficiency is a critical aspect of power supplies, impacting both performance and energy costs. The 27W PD USB C GaN Power Supply is designed for optimal performance with the Raspberry Pi 5, but specific efficiency metrics are not detailed in its specifications. However, it does include built-in safety features to ensure reliable operation.

On the other hand, the MEAN WELL LRS-100-24 boasts an impressive energy efficiency of 90%. This high efficiency minimizes power loss, making it an ideal choice for applications where energy consumption is a concern. This level of efficiency is especially beneficial in industrial settings, where prolonged usage can lead to significant savings in energy costs.

Safety Features

Safety features are essential in any power supply to protect connected devices and users. The 27W PD USB C GaN Power Supply includes multiple built-in safety mechanisms, including over-current protection, over-voltage protection, and short-circuit protection. These features ensure that the Raspberry Pi 5 and other connected devices operate safely without risk of damage.

Conversely, the MEAN WELL LRS-100-24 also emphasizes safety with full protection against overvoltage, overload, and short circuits. It has undergone extensive burn-in testing and is certified to safety standards such as CE and IEC/EN 62368-1. Such rigorous safety protocols make it a reliable choice for critical applications in industrial environments.

Size and Portability

Portability is an essential consideration for many users, especially those who require flexibility in their power supply solutions. The 27W PD USB C GaN Power Supply is compact, with dimensions of 60mm x 40mm x 26.5mm, making it easy to carry and ideal for on-the-go use with the Raspberry Pi 5.

The MEAN WELL LRS-100-24 is less portable due to its larger size, measuring 159mm x 97mm x 30mm. While it is designed for stationary use in industrial applications, its metal mesh housing does facilitate superior heat dissipation, which is crucial for performance in fixed installations. Users needing a power supply that can easily be transported may prefer the Vemico option.

Intended Use Cases

The intended use cases for these power supplies significantly differ, influencing their design and features. The 27W PD USB C GaN Power Supply is specifically aimed at hobbyists and developers using the Raspberry Pi 5, making it an excellent choice for personal projects, DIY applications, and educational purposes.

In contrast, the MEAN WELL LRS-100-24 is geared toward industrial and commercial applications. With its high power output and robust construction, it is suitable for use in automation systems, control panels, and various electronic instruments. Users in these fields will benefit from the reliability and efficiency of the MEAN WELL power supply.

Which should you buy?

In conclusion, the choice between the 27W PD USB C GaN Power Supply for Raspberry Pi 5 and the MEAN WELL LRS-100-24 AC/DC Switching Power Supply boils down to your specific needs. If you require a compact, portable power supply for a Raspberry Pi 5, the Vemico option at C$21.39 is an excellent fit.
