GeeekPi 18W 5V 3.6A Power Supply for Raspberry Pi 4 vs MEAN WELL LRS-100-24 AC/DC Switching Power Supply 108W 24V 4.5A Single Output fo

Overview of the Products

In this comparison, we will examine the GeeekPi 18W 5V 3.6A Power Supply for Raspberry Pi 4 and the MEAN WELL LRS-100-24 AC/DC Switching Power Supply. The GeeekPi power supply is specifically designed for Raspberry Pi devices, while the MEAN WELL unit caters to a broader range of industrial and commercial applications. Priced at C$16.99, the GeeekPi power supply offers targeted functionality for hobbyists and developers using Raspberry Pi. In contrast, the MEAN WELL model, with a price of C$32.95, is built for high-efficiency performance in various professional settings.

Design and Build Quality

The build quality of both power supplies reflects their intended usage. The GeeekPi power supply is compact, designed primarily for Raspberry Pi devices, featuring a Type-C input and an integrated ON/OFF switch for user convenience. Its extended cord measures 120cm, which adds flexibility for setup. On the other hand, the MEAN WELL power supply boasts a robust metal mesh housing that enhances heat dissipation, promoting longevity and reliability. Its slim 30mm profile is particularly advantageous for installations with limited space. Both units exhibit quality construction, but the MEAN WELL provides a more industrial-grade option.

Power Output and Efficiency

The power output is a significant differentiator between the two products. The GeeekPi power supply provides a stable output of 5V and 3.6A, amounting to a total power output of 18W. This is sufficient for powering Raspberry Pi 4 devices under typical conditions. Conversely, the MEAN WELL unit delivers a more substantial output of 24V and 4.5A, equating to a total of 108W. This high output makes it suitable for demanding applications that require consistent power delivery. Moreover, the MEAN WELL power supply claims an impressive 90% energy efficiency, minimising power loss during operation, which is a crucial factor for users looking to reduce energy costs.

Certifications and Safety Features

Safety certifications play a vital role in determining the reliability of power supplies. The GeeekPi power supply comes with multiple certifications, including UL Listed Certification, TUV, and RoHS, ensuring that it meets safety standards for consumer electronics. It also includes various protection features such as overvoltage, undervoltage, over temperature, overcurrent, and short circuit protection. Meanwhile, the MEAN WELL power supply is safety-certified to CE, IEC/EN 62368-1, and EN 61558 standards. It features additional protective measures, including automatic recovery from overload and overvoltage conditions. While both products offer robust safety features, the MEAN WELL unit provides a more comprehensive suite of protections tailored for industrial use.

Input Voltage Compatibility

Input voltage compatibility is a critical consideration for users operating in diverse geographical regions. The GeeekPi power supply accepts a universal input range of 100-240V AC, making it suitable for a variety of electrical systems. This versatility is essential for users who may travel or relocate their Raspberry Pi setups. In contrast, the MEAN WELL power supply supports an even broader input voltage range of 85-264VAC, withstanding surge inputs of 300VAC for up to five seconds. This capability ensures that it can function reliably in different environments, including those prone to voltage fluctuations, further enhancing its appeal for industrial applications.

Applications and Use Cases

When assessing the applications of these power supplies, it’s clear that they cater to different audiences. The GeeekPi power supply is specifically engineered for use with Raspberry Pi devices, making it an excellent choice for hobbyists, educators, and developers working on small projects or learning about electronics. Its design includes features that simplify powering on and off a Raspberry Pi setup. Conversely, the MEAN WELL power supply is suited for a wide range of industrial and commercial applications, such as automation systems and electronic instrumentation. Its higher power output and rugged design make it ideal for demanding environments, appealing to professionals in need of reliable power solutions.

Price Comparison

Price is a significant factor in any purchasing decision. The GeeekPi power supply retails for C$16.99, making it an affordable option for those specifically looking to power Raspberry Pi devices without breaking the bank. In comparison, the MEAN WELL power supply is priced at C$32.95, reflecting its enhanced capabilities and suitability for industrial applications. While the initial cost of the MEAN WELL unit is higher, the investment may be justified by its greater efficiency, durability, and versatility in various settings. Buyers must consider their specific needs and whether the additional features of the MEAN WELL justify the price difference.

Which should you buy?

When deciding between the GeeekPi 18W 5V 3.6A Power Supply and the MEAN WELL LRS-100-24 AC/DC Switching Power Supply, your choice largely depends on your specific requirements. If you are a Raspberry Pi enthusiast looking for a budget-friendly and easy-to-use power supply, the GeeekPi is a suitable option. However, if you need a robust, high-efficiency power supply for industrial applications or projects requiring more power, the MEAN WELL unit is the better choice due to its greater output and advanced safety features. Ultimately, understanding your power needs will guide you to the right product for your situation.
