Overview of the Raspberry Pi Power Supply and NVVV MDR-20-12
The Raspberry Pi Power Supply and the NVVV MDR-20-12 are both reliable power solutions, but they serve different purposes. The Raspberry Pi Power Supply is specifically designed for Raspberry Pi devices, while the NVVV MDR-20-12 is a versatile DIN-rail power supply that can power various electronic devices. Understanding their features can help you choose the right one for your needs.
Compatibility and Design
The Raspberry Pi Power Supply excels in compatibility, designed exclusively for Raspberry Pi 3 Model B, B+, and R-Pi 2 Model B+. It supports a range of current outputs from 1A to 2.5A, making it highly suitable for various Raspberry Pi applications. On the other hand, the NVVV MDR-20-12 provides a standard output voltage of 12V and a current output of 1.67A, which makes it a more general-purpose solution for devices that can operate on 12V DC. This difference in design reflects their intended uses: the Raspberry Pi Power Supply for specific Raspberry Pi models and the NVVV for broader applications.
Power Output and Efficiency
When considering power output, the Raspberry Pi Power Supply delivers a maximum output of 5V at 3A, which is sufficient for powering Raspberry Pi units effectively. In contrast, the NVVV MDR-20-12 features an output voltage of 12V and a maximum power output of 20W. This means that while the Raspberry Pi Power Supply is tailored for low-voltage devices, the NVVV can handle a wider range of applications that require higher voltage, making it more versatile in terms of power efficiency.
Cable Length and Installation
One notable feature of the Raspberry Pi Power Supply is its 6-foot cable, which provides ample length for flexible installation and operation of your Raspberry Pi, reducing the hassle of finding a nearby outlet. On the other hand, the NVVV MDR-20-12 is designed for DIN-rail installation, which is ideal for industrial settings where space and organisation are crucial. However, it does not specify any cable length, which may limit installation flexibility compared to the Raspberry Pi Power Supply.
Safety and Certification
Safety is an important consideration for any power supply. The Raspberry Pi Power Supply is certified by ETL, CE, and FCC, ensuring it meets safety standards for consumer electronics. This certification offers peace of mind for users who are concerned about the safety of their devices. The NVVV MDR-20-12 does not provide specific safety certifications in the data presented, which could be a deciding factor for users prioritising certified products in their setups.
Price Comparison
In terms of pricing, the Raspberry Pi Power Supply is more affordable, priced at C$18.99, while the NVVV MDR-20-12 comes at C$21.41. This difference of C$2.42 may seem minor, but for those on a budget or looking to equip multiple devices, the cost can add up. The price point of the Raspberry Pi Power Supply makes it an attractive option for Raspberry Pi enthusiasts who want to avoid overspending.
Target Audience and Use Cases
The Raspberry Pi Power Supply is targeted towards Raspberry Pi users, making it an ideal choice for hobbyists and developers working with these mini-computers. Its design and power output are optimised for the specific needs of Raspberry Pi devices. In contrast, the NVVV MDR-20-12 appeals to a broader audience, including industrial users and those needing a reliable power supply for various electronic systems that require a 12V input. This distinction highlights the specific user base each product aims to serve.
Which should you buy?
Choosing between the Raspberry Pi Power Supply and the NVVV MDR-20-12 ultimately depends on your specific needs. If you're looking for a dedicated power solution for your Raspberry Pi, the Raspberry Pi Power Supply is the clear winner with its compatibility, safety certifications, and longer cable length. Conversely, if you need a more versatile power supply for different devices requiring 12V input, the NVVV MDR-20-12 is a solid option, offering a higher voltage output and broader application potential.
