NVVV MDR-20-12 AC to DC DIN-Rail Power Supply 12V 1.67 Amp 20W vs 27W PD USB C GaN Power Supply for Raspberry Pi 5 Adapter 5.1V 5A

Overview of the Products

In this comparison, we are looking at two power supplies: the NVVV MDR-20-12 AC to DC DIN-Rail Power Supply and the Vemico 27W PD USB C GaN Power Supply. The NVVV power supply is priced at C$21.41, while the Vemico model is slightly cheaper at C$21.39. Both products aim to provide reliable power for different applications, but their specifications and intended uses differ significantly.

Design and Build Quality

The NVVV MDR-20-12 features a DIN-rail design, making it suitable for mounting in electrical panels or enclosures. Its robust build is ideal for industrial applications. On the other hand, the Vemico GaN Power Supply is compact and portable, measuring just 60mm x 40mm x 26.5mm. This makes it easy to carry, particularly for users who need a power source for mobile applications like the Raspberry Pi 5. Each design serves a unique purpose, with NVVV focusing on stationary use and Vemico prioritizing portability.

Power Output and Compatibility

The NVVV MDR-20-12 provides a steady output of 12V and a maximum current of 1.67 Amps, translating to a maximum output power of 20 Watts. This makes it suitable for various low to moderate power applications. In contrast, the Vemico power supply offers a more versatile output range with 5.1V at 5A, 9V at 3A, 12V at 2.25A, and 15V at 1.8A, making it compatible with the Raspberry Pi 5 and other devices requiring variable voltage. Thus, if you need a flexible power supply, the Vemico is the clear choice.

Input Voltage Range

The NVVV power supply supports an input voltage range of 85 to 264 VAC, making it adaptable for use in various regions with different electrical standards. This broad range ensures that it can function efficiently in many environments. Conversely, the Vemico power supply also supports an input of AC100-240V, 50/60Hz, ensuring compatibility across different regions. Both products provide good flexibility for international use, but the NVVV’s wider range may offer additional peace of mind in fluctuating voltage situations.

Safety Features

Safety is paramount when dealing with electrical devices, and both power supplies come equipped with protective features. The NVVV MDR-20-12 does not explicitly list safety features in the provided information, which may be a consideration for potential users. In contrast, the Vemico power supply highlights built-in protections against over-current, over-voltage, and short-circuit scenarios. This focus on safety makes the Vemico a more reassuring choice for users who prioritize the protection of connected devices.

Application Suitability

The NVVV MDR-20-12 is designed primarily for fixed applications, providing stable power for equipment that requires a steady 12V output. Its DIN-rail mounting makes it ideal for industrial settings, control systems, and other applications where space is at a premium. The Vemico GaN Power Supply, however, is specifically designed for the Raspberry Pi 5, offering various voltage options that make it highly versatile for hobbyists and developers. If your primary use is with a Raspberry Pi, the Vemico is more suited to your needs.

Price Comparison

When it comes to pricing, the NVVV MDR-20-12 is available for C$21.41, while the Vemico power supply is slightly cheaper at C$21.39. The difference in price is minimal, but when considering the features and intended use, the Vemico appears to offer better value, especially for users needing a power supply for the Raspberry Pi 5. The small price difference may influence buyers leaning towards the more versatile Vemico option.

Which should you buy?

Choosing between the NVVV MDR-20-12 and the Vemico 27W PD USB C GaN Power Supply ultimately depends on your specific needs. If you require a stable 12V power source for industrial applications, the NVVV model is a reliable choice. However, if you're looking for a versatile, portable power supply specifically for the Raspberry Pi 5, the Vemico is the better option due to its compatibility and safety features. Given the slight price advantage and enhanced functionality, the Vemico power supply stands out as the more appealing choice for most users.
