GeeekPi 20W 5V 4A Power Supply for Raspberry Pi 4/Orange Pi 5/5B vs NVVV MDR-20-12 AC to DC DIN-Rail Power Supply 12V 1.67 Amp 20W

Overview of the Products

The GeeekPi 20W 5V 4A Power Supply is priced at C$31.40, while the NVVV MDR-20-12 AC to DC DIN-Rail Power Supply costs C$21.41. The price difference reflects their differing functionalities and target applications. The GeeekPi is tailored for use with Raspberry Pi devices, while the NVVV is designed for broader applications that require a DIN-rail power supply. Understanding these distinctions will help in determining which product better suits your needs.

Design and Build Quality

The design of the GeeekPi power supply includes a Type-C to Micro USB power adapter, specifically catering to Raspberry Pi models 4 and 3B+/3B, while also accommodating Orange Pi devices. The built-in ON/OFF switch adds convenience for users, allowing easy control over the power supply. In contrast, the NVVV power supply is a compact DIN-rail model, designed for easy integration into various electrical systems. Both units feature high-quality components, but the GeeekPi's additional adapter and switch enhance its user-friendliness, making it ideal for hobbyists and developers.

Compatibility

Compatibility is a significant factor where the GeeekPi shines. It is expressly designed for Raspberry Pi 4, 3B+, and 3B, along with compatibility for Orange Pi 5 and 5B. This makes it a highly targeted solution for users engaged in projects with these specific devices. Meanwhile, the NVVV power supply operates at 12V and is suitable for a broader range of applications requiring DIN-rail mounting. For users specifically needing to power Raspberry Pi or Orange Pi devices, the GeeekPi is the clear choice, while the NVVV is better suited for industrial or general-purpose use.

Power Output

The GeeekPi power supply provides an output of 5V at 4A, delivering a maximum of 20W, which is optimal for powering Raspberry Pi devices that require stable low-voltage power. In contrast, the NVVV supply offers 12V at 1.67A, also maxing out at 20W. The difference in voltage output signifies that the two products cater to different requirements; the GeeekPi is tailored for low-voltage applications, while the NVVV can be integrated into systems that require higher voltage. Depending on your project needs, this can be a critical factor in your decision.

Safety Features

Safety is paramount in power supplies, and both products offer various protective features. The GeeekPi power supply boasts multiple protections, including over-voltage, under-voltage, over-temperature, over-current, and short circuit protection. This level of safety is essential for those working with sensitive electronics like the Raspberry Pi. On the other hand, the NVVV power supply does not list specific safety features but operates within a broad input voltage range of 85 to 264V, which indicates a robust design. However, the GeeekPi's comprehensive protection features make it a safer bet for individual users focusing on electronic projects.

Cord Length and Installation

The GeeekPi power supply comes with an extended cord measuring 120cm, which provides flexibility in positioning the power supply relative to the devices it powers. This is particularly useful for setups where space is a concern. In contrast, the NVVV power supply is designed for DIN-rail installation, which is ideal for organized and space-efficient setups in industrial environments. While the GeeekPi caters to home and project use with its longer cord, the NVVV's mounting style suits professional applications better.

Price Comparison

With a price point of C$31.40, the GeeekPi is more expensive than the NVVV at C$21.41. This price difference reflects the specialized features that the GeeekPi offers, making it more suitable for specific Raspberry Pi applications. The NVVV, while cheaper, provides general-purpose functionality that may not cater to the specific requirements of Raspberry Pi users. Therefore, the choice largely depends on whether you need the specialized features of the GeeekPi or prefer the cost-effective generality of the NVVV.

User Applications

The GeeekPi power supply is particularly beneficial for hobbyists and developers working on Raspberry Pi projects, thanks to its dedicated design and user-friendly features. It is ideal for DIY electronics, robotics, and educational purposes. Conversely, the NVVV power supply’s DIN-rail design makes it more applicable in industrial settings or for users needing a versatile power supply for various electronic projects. Users should consider their specific applications when choosing between these two power supplies.

Which should you buy?

Ultimately, the decision between the GeeekPi 20W 5V 4A Power Supply and the NVVV MDR-20-12 AC to DC DIN-Rail Power Supply boils down to your specific needs. If you are working on Raspberry Pi projects and require a power supply that offers tailored features, comprehensive safety, and user-friendliness, the GeeekPi is the better choice despite its higher price. However, if your requirements are more general, or if you need a power supply for a broader range of applications, the NVVV offers good performance at a lower price point. Choose based on your project requirements and desired functionalities.
