Overview of the Products
The GeeekPi USB-C Power Supply UK Plug for Raspberry Pi 4 is priced at £11.99, while the 5V 4A Power Supply Adapter costs £14.96. Both products serve as power supplies but cater to slightly different requirements. The GeeekPi model is specifically designed for Raspberry Pi devices, boasting a special USB-C connector and an on/off switch, whereas the COLM power supply offers broader compatibility with a variety of devices, featuring a barrel connector.
Compatibility
The GeeekPi power supply is tailored for Raspberry Pi 4 models, making it an ideal choice for users of this specific platform. It also includes a USB-C to Micro USB adapter, supporting older Raspberry Pi models such as the 3B+ and 3B, along with compatibility for devices like the Orange Pi. In contrast, the COLM power supply is compatible with a wider range of devices, including the Jetson Nano and Odroid XU4, making it suitable for users who may need to power various electronics. While the GeeekPi focuses on a niche, the COLM provides versatility for different setups.
Power Output
The GeeekPi power supply delivers a reliable output of 5V and 3.6A, which translates to 18W of power. This is sufficient for the Raspberry Pi 4, ensuring stable operation. Conversely, the COLM power supply provides a higher output of 5V and 4A, equating to 20W. This means it can handle more demanding devices and provides a safer option for users who may require additional power. The difference in amperage can be crucial for performance, particularly in power-intensive applications.
Safety Features
Both power supplies incorporate essential safety features, but they differ in their offerings. The GeeekPi power supply includes multiple protection functions, such as over-current and short-circuit protection, ensuring safe operation for your Raspberry Pi. Additionally, it comes with UKCA and RoHS certification, highlighting its compliance with safety standards. The COLM power supply also boasts safety certifications, including CE, FCC, and PSE, alongside features like automatic overload cut-off and thermal cut-off. This emphasis on safety is crucial for users concerned about device protection.
Design and Usability
The GeeekPi power supply boasts a design that includes an on/off switch, enabling users to conveniently power their Raspberry Pi on and off without unplugging the device. This feature enhances usability, especially for those who frequently turn their device on and off. The COLM power supply, while lacking a power switch, offers a long power cord of about 120cm, allowing for flexible placement of devices. Each design serves its purpose, with the GeeekPi prioritising convenience and the COLM focusing on reach.
Cable Length and Flexibility
The cable length of the GeeekPi power supply measures 120cm, which is adequate for most setups involving Raspberry Pi devices. This length allows for reasonable flexibility in positioning the device without being overly restrictive. The COLM power supply has a slightly longer cable, offering a total of approximately 110cm for the DC cable and about 120cm for the power cord. This added length can be advantageous for users needing to position their devices further from the power source, making it a more flexible option in some scenarios.
Price Comparison
The pricing of these power supplies reflects their intended purpose and features. The GeeekPi is priced at £11.99, making it a cost-effective option for Raspberry Pi users needing a dedicated power supply. In contrast, the COLM power supply is priced higher at £14.96, which can be justified by its broader compatibility and higher power output. While the GeeekPi offers a more affordable solution for specific users, the COLM might be worth the investment for those who need versatility across multiple devices.
Which should you buy?
The decision between the GeeekPi USB-C Power Supply and the COLM 5V 4A Power Supply Adapter ultimately hinges on your specific needs. If you are a Raspberry Pi user seeking a reliable and affordable power supply with additional features like an on/off switch, the GeeekPi at £11.99 is an excellent choice. However, if you require a power supply that caters to various electronics, especially those needing higher power, the COLM at £14.96 offers greater versatility and a higher output, making it a strong contender. Consider your device compatibility and power requirements carefully to make the best choice for your setup.
