GeeekPi 20W 5V 4A Power Supply for Raspberry Pi 4/Orange Pi 5/5B vs MEAN WELL LRS-100-24 AC/DC Switching Power Supply 108W 24V 4.5A Single Output fo

Power Output and Compatibility

The GeeekPi 20W 5V 4A Power Supply provides a 20-watt output at 5 volts and 4 amps, making it specially designed for Raspberry Pi 4, Raspberry Pi 3B+/3B, and Orange Pi 5/5B devices. In contrast, the MEAN WELL LRS-100-24 offers a significantly higher 108-watt output at 24 volts and 4.5 amps, targeting industrial and commercial applications.

GeeekPi’s power supply is purpose-built for single-board computers like the Raspberry Pi 4, delivering the exact 5V 4A output these devices require. It even includes a Type-C to Micro USB adapter for older Pi models. On the other hand, MEAN WELL’s LRS-100-24 is an AC/DC switching power supply designed for broader uses, including automation systems and control panels, with a 24V output that is unsuitable for powering Raspberry Pi devices directly without additional voltage regulation.

In summary, GeeekPi is ideal for hobbyists or developers working specifically with Raspberry Pi or Orange Pi boards, while MEAN WELL serves industrial equipment needing higher wattage and voltage.

Build Quality and Design

When it comes to build quality, both products offer reliable construction but cater to different environments. The GeeekPi power supply includes a 120 cm cord and features a high-quality copper wire core with an inline noise filter to ensure stable power transmission, supported by certifications such as UL Listed, TUV, and RoHS. It also has an ON/OFF switch for easy power control, which is convenient for desktop or lab setups.

The MEAN WELL LRS-100-24 boasts a compact design with a slim 30 mm profile and a metal mesh housing that enables superior heat dissipation and fanless operation. It has undergone 100% burn-in testing and is rated for high-altitude operation up to 5,000 meters, reflecting its ruggedness for challenging industrial environments. Its IP31-level protection guards against particulate ingress, adding to its durability.

Overall, GeeekPi emphasizes user-friendly features and certifications for consumer electronics, while MEAN WELL prioritizes durability and thermal management for industrial use.

Safety and Protection Features

Both power supplies provide comprehensive protection mechanisms, but with differences suited to their respective applications. The GeeekPi power supply includes multiple protection functions such as over voltage, under voltage, over temperature, over current, and short circuit protection. These safeguards are critical for sensitive single-board computers and ensure stable operation.

The MEAN WELL LRS-100-24 also offers full protection against overvoltage, overload, and short circuits, with automatic recovery features for overvoltage and overload conditions. Additionally, it has a low no-load power consumption of less than 0.5 watts, which improves energy efficiency during idle periods. MEAN WELL’s product meets CE, IEC/EN 62368-1, and EN 61558 safety standards, underscoring its industrial-grade compliance.

In short, both units deliver robust safety features, but MEAN WELL’s protections are tailored for industrial reliability with automatic recoveries, while GeeekPi covers essential protections for consumer electronics.

Energy Efficiency and Performance

Energy efficiency is a standout aspect of the MEAN WELL LRS-100-24, which achieves approximately 90% efficiency, significantly reducing power loss and heat generation. This efficiency level is beneficial in industrial settings where power consumption and thermal management are critical.

GeeekPi’s power supply, while stable and tested for power delivery, does not specify an energy efficiency rating. Its focus is on providing stable 5V 4A power with high-quality copper wiring and an inline noise filter, which helps maintain signal integrity but does not directly address efficiency metrics.

For performance, the MEAN WELL unit maintains stable output under a continuous 4.5A load with ±1% voltage regulation accuracy and less than 150mVp-p ripple noise. GeeekPi’s product is designed to meet the power stability needs of Raspberry Pi 4 and similar devices but lacks detailed performance data on voltage regulation and ripple.

Thus, MEAN WELL offers superior energy efficiency and detailed performance specs tailored for demanding applications, while GeeekPi focuses on reliable power delivery specific to Raspberry Pi.

Input Voltage and Global Compatibility

The MEAN WELL LRS-100-24 features a universal AC input voltage range of 85 to 264 VAC and can handle 120 to 373 VDC, making it compatible with global power standards. It is also capable of withstanding 300 VAC surge inputs for up to five seconds without damage, which is important for industrial environments with unstable power supply conditions.

GeeekPi’s power supply supports a wide input range of 100 to 240 V AC at 50/60 Hz, covering most household and office power standards worldwide. This ensures it can operate reliably in different regions without voltage converters.

While both products offer international compatibility, MEAN WELL’s wider input voltage range and surge tolerance make it better suited for harsh or variable power environments.

Price and Value

The GeeekPi 20W 5V 4A Power Supply is available for C$31.40, while the MEAN WELL LRS-100-24 is priced slightly higher at C$32.95. The price difference of just C$1.55 is minimal, but the products serve very different markets.

GeeekPi provides a budget-conscious solution tailored to Raspberry Pi enthusiasts who need a reliable, certified power supply with features like an ON/OFF switch and adapter for older Pi models. MEAN WELL offers a more industrial-grade power supply with greater wattage, voltage, energy efficiency, and rugged construction, justifying its marginally higher price.

Ultimately, the value depends on the intended use: GeeekPi is a cost-effective choice for hobbyist and small-scale users, while MEAN WELL provides industrial performance and durability at a slightly higher cost.

Applications and Use Cases

GeeekPi’s power supply is purpose-built for powering Raspberry Pi 4, Raspberry Pi 3B+/3B, and Orange Pi 5/5B devices, making it ideal for developers, makers, and educators working with these single-board computers. Its USB-C connector and included adapter enhance usability across these models, and the ON/OFF switch adds convenience for repeated use.

In contrast, the MEAN WELL LRS-100-24 targets industrial and commercial applications such as automation systems, control panels, electronic instruments, and electromechanical equipment. Its ability to operate fanlessly over a wide temperature range (-30°C to +70°C), high-altitude capability, and comprehensive protections make it suitable for harsh environments.

Thus, the GeeekPi power supply fits the needs of tech hobbyists and educators, while MEAN WELL’s LRS-100-24 is engineered for demanding industrial scenarios.

Which should you buy?

Your choice depends primarily on your power requirements and application. If you need a reliable, certified power supply specifically for Raspberry Pi 4, Raspberry Pi 3B+/3B, or Orange Pi 5/5B at a budget-friendly price of C$31.40, the GeeekPi 20W 5V 4A Power Supply is the clear option. It delivers the exact 5V 4A output, includes a handy ON/OFF switch, and comes with the necessary adapters.

Alternatively, if your application demands a higher wattage (108W), 24V output power supply with industrial-grade safety certifications, fanless operation, and superior energy efficiency at approximately 90%, the MEAN WELL LRS-100-24 at C$32.95 is the better investment. Its rugged design and wide input voltage range ensure reliable operation in challenging environments.

In summary, choose GeeekPi for single-board computer projects needing 5V 4A power, and MEAN WELL for industrial or commercial equipment requiring robust, higher-voltage power supplies.
