Miuzei Power Supply for Raspberry Pi 4 vs Official Raspberry Pi 5 27W USB-C Power Supply

Power Output and Compatibility

The Official Raspberry Pi 5 27W USB-C Power Supply delivers significantly higher power output compared to the Miuzei Power Supply for Raspberry Pi 4. The Raspberry Pi 5 supply can provide up to 5.1V at 5A, equating to 25.5W of power, while the Miuzei offers a fixed output of 5V at 3A, totalling 15W. This means the official supply supports much more demanding power needs, particularly for the Raspberry Pi 5’s advanced features and peripherals. In contrast, the Miuzei is designed for Raspberry Pi 4 and 3 models, with a stable 5V 3A output sufficient for those devices but not for higher loads. Users requiring power for the latest Pi 5 or high-draw USB accessories will benefit from the official 27W supply’s elevated capacity.

Design and Build Features

Both power supplies cater to their target Raspberry Pi models with thoughtful design features, but the Miuzei offers a notable convenience with an integrated on/off switch. This switch allows users to power on and off their Raspberry Pi 4 without unplugging, a practical feature for frequent use or testing scenarios. The Miuzei also includes a 5ft (1.5m) cable, giving decent reach for typical desktop setups. The official Raspberry Pi 5 power supply, meanwhile, includes a 1.2m 17AWG USB-C cable designed for robust power delivery and compliance with Power Delivery standards. It comes equipped with a Canada/US plug, ensuring compatibility and safety for local users. The official power supply’s design focuses on providing stable power even under full load, reflecting its role as the recommended accessory for the Raspberry Pi 5.

Protection and Safety Mechanisms

When it comes to safety features, the Miuzei Power Supply explicitly highlights multiple protection designs, including over voltage, under voltage, short circuit, overheat, and overcurrent protections. These safeguards ensure reliable and safe operation for Raspberry Pi 4 and 3 models, reducing risk of damage from electrical faults. The official Raspberry Pi 5 power supply does not list specific protection features in the provided data, but as an official accessory designed for modern Power Delivery profiles, it is expected to meet high safety and stability standards. However, based on the descriptions, Miuzei’s clear emphasis on multiple protections may appeal to users prioritizing explicit safety measures.

Power Delivery and Versatility

The Official Raspberry Pi 5 power supply supports multiple power profiles under the USB Power Delivery (PD) protocol: 5.1V at 5A, 9V at 3A, 12V at 2.25A, and 15V at 1.8A, all capped at 27W. This versatility means it can power not only the Raspberry Pi 5 but also various PD-compatible third-party devices, including peripherals like hard drives and SSDs. By comparison, the Miuzei supply provides a fixed 5V 3A output with no mention of Power Delivery support, limiting its use to Raspberry Pi 4 and 3 models and less demanding peripherals. For users looking for a power supply with broader compatibility across different devices and power profiles, the official Raspberry Pi 5 supply offers a clear advantage.

Price and Value

Price-wise, the Miuzei Power Supply for Raspberry Pi 4 is considerably more affordable at C$16.99, nearly half the cost of the Official Raspberry Pi 5 27W USB-C Power Supply, which is priced at C$31.90. For users with Raspberry Pi 4 or 3 who do not require the higher power output or advanced PD profiles, the Miuzei supply provides good value without compromising on basic functionality and safety features. However, for those needing higher power delivery or compatibility with the latest Raspberry Pi 5 and its peripherals, the higher price of the official supply is justified by its enhanced capabilities and official support.

Cable and Connector Considerations

The Miuzei supply uses a Type-C connection with a 5ft (1.5m) cable length, which offers reasonable flexibility in placement. The official Raspberry Pi 5 power supply also uses USB Type-C but includes a slightly shorter 1.2m cable made from 17AWG wire, which is thicker and better suited to handle higher current loads safely. The official power supply’s cable and plug are tailored to Canadian and US standards, potentially offering better compatibility and durability for users in those regions. In contrast, the Miuzei’s longer cable might be more convenient for setups requiring extra reach but may not support the same current levels as effectively.

Target Audience and Use Cases

The Miuzei Power Supply is clearly aimed at Raspberry Pi 4 and 3 users who need a reliable, straightforward charger with an added on/off switch for convenience. It suits hobbyists and general users who do not require high power or advanced PD functionality. The Official Raspberry Pi 5 27W USB-C Power Supply, on the other hand, is designed to meet the demands of the new Raspberry Pi 5 platform, including high-power peripherals and third-party PD-compatible devices. This makes it the preferred choice for users with newer hardware or those who intend to run power-hungry accessories such as external drives.

Which should you buy?

The choice depends primarily on your Raspberry Pi model and power needs. If you own a Raspberry Pi 4 or 3 and want an affordable, reliable power supply with an on/off switch and solid protection features, the Miuzei Power Supply for Raspberry Pi 4 at C$16.99 is a practical option. However, if you have a Raspberry Pi 5 or require a power supply capable of delivering up to 27W with multiple Power Delivery profiles for high-power peripherals, the Official Raspberry Pi 5 27W USB-C Power Supply at C$31.90 is the better investment. It offers superior power output, official compatibility, and enhanced versatility, justifying the higher price for users with more demanding setups.
