Price Comparison
When considering price, the iRasptek 27W USB-C Power Supply is the more economical option, priced at C$21.99 compared to the Official Raspberry Pi 5 27W USB-C Power Supply, which retails for C$31.90. This marks a difference of C$9.91, making the iRasptek a budget-friendly alternative without sacrificing essential features. For users looking to save while powering their Raspberry Pi 5, the lower price point of the iRasptek could be a significant factor in their purchasing decision.
Power Delivery Capabilities
Both power supplies offer robust power delivery capabilities, providing multiple output options. The Official Raspberry Pi 5 power supply delivers 5.1V at 5A, along with additional profiles of 9V at 3A, 12V at 2.25A, and 15V at 1.8A, all limited to a maximum of 27W. Similarly, the iRasptek also provides the same output specifications: 5.1V at 5A, 9V at 3A, 12V at 2.25A, and 15V at 1.8A. This means that both options are equally capable of powering high-demand peripherals like hard drives and SSDs, making them suitable for users who require reliable performance.
Cable Length
Cable length is an important consideration for usability, especially in larger setups. The Official Raspberry Pi 5 comes with a 1.2m cable, while the iRasptek offers a slightly longer 1.5m cable. The extra 0.3m of the iRasptek may provide more flexibility in positioning your Raspberry Pi 5, allowing for greater convenience in various setups. This difference can be particularly beneficial in situations where the power outlet is not in close proximity to the device.
Input Compatibility
Both power supplies are designed for international use, with an input voltage range of 100-240V AC and frequency of 50/60Hz. This means that both the Official Raspberry Pi 5 and the iRasptek power supply can be used in a variety of regions without any compatibility issues. Users can feel confident that either option will function well in different electrical environments, making them suitable for travel or international deployment.
Design and Build Quality
While specific design elements are not detailed in the provided data, both power supplies are from reputable brands in the Raspberry Pi community. The Official Raspberry Pi 5 is likely to have a design that aligns closely with Raspberry Pi's branding, ensuring aesthetic consistency for devoted fans. On the other hand, the iRasptek may offer a more generic look; however, it has undergone extensive compliance testing to meet various regional and international standards. This compliance signifies a commitment to quality and safety in its construction.
Automatic Current Limiting
An interesting feature of the iRasptek 27W USB-C Power Supply is its capability for automatic current limiting. This allows the power supply to communicate with the Raspberry Pi 5 and increase the USB current limit automatically from the default 600mA to 1.6A. While the Official Raspberry Pi 5 power supply offers stable power, it does not explicitly mention this automatic limit increase feature. This could be a deciding factor for users who need additional power for devices connected to the USB ports.
Versatility with Third-Party Products
Both power supplies have been designed with versatility in mind, allowing for the powering of third-party PD-compatible products. The built-in power profiles of both units—5.1V at 5A, 9V at 3A, 12V at 2.25A, and 15V at 1.8A—make them suitable for a range of devices. However, the iRasptek explicitly mentions its support for automatic power adjustments, which may enhance its compatibility with various peripherals. This feature can be advantageous for users who regularly connect different types of devices to their Raspberry Pi 5.
Which should you buy?
In conclusion, the choice between the Official Raspberry Pi 5 27W USB-C Power Supply and the iRasptek 27W USB-C Power Supply largely depends on budget and specific needs. The iRasptek is the more affordable option at C$21.99, offering similar power delivery capabilities and a longer cable length. However, the Official Raspberry Pi 5 power supply comes with the brand assurance of Raspberry Pi and provides reliable performance for those who prioritize brand loyalty. If budget is a primary concern, the iRasptek emerges as the clear winner, while those seeking brand consistency may lean towards the Official Raspberry Pi offering.
