GeeekPi 18W 5V 3.6A Power Supply for Raspberry Pi 4 vs iRasptek 27W USB-C Power Supply with PD for Raspberry Pi 5（5.1V/5A）

Pricing Comparison

When it comes to pricing, the GeeekPi 18W 5V 3.6A Power Supply is more budget-friendly than the iRasptek 27W USB-C Power Supply. The GeeekPi is priced at C$16.99, while the iRasptek is available for C$21.99. This C$5 difference could be a deciding factor for users who are looking to save costs while still ensuring their Raspberry Pi devices are powered adequately. The lower price of the GeeekPi may appeal to casual users or those on a tight budget, whereas the iRasptek's higher price reflects its advanced features, including higher power output capabilities.

Compatibility with Raspberry Pi Models

The GeeekPi power supply is specifically designed for the Raspberry Pi 4, but it also comes with an adapter for Raspberry Pi 3B+/3B models. This makes it a versatile choice for users who own multiple versions of the Raspberry Pi. On the other hand, the iRasptek power supply is tailored for the Raspberry Pi 5, providing compatibility with the latest model and its high-power peripherals. For users who are upgrading to the Raspberry Pi 5, the iRasptek offers more relevant features, while those still using older models may find the GeeekPi to be sufficient for their needs.

Power Output and Efficiency

Power output is a significant differentiator between the two products. The GeeekPi provides 18W of power at 5V and 3.6A, which is adequate for basic operations of the Raspberry Pi 4. In contrast, the iRasptek offers a much higher output of 27W, with the capability of delivering 5.1V at 5A. This higher output is particularly beneficial for powering high-demand peripherals such as external hard drives, making the iRasptek a more efficient choice for users who require additional power. The difference in power output can greatly affect the performance of connected devices, especially for those utilizing the Raspberry Pi 5.

Cable Length and Design

The length of the power cord is another point of comparison. The GeeekPi comes with a 120cm cord, providing a reasonable reach for most setups. Meanwhile, the iRasptek features a longer 1.5m (150cm) cable, which offers more flexibility in terms of placement and setup for your Raspberry Pi. A longer cable can be particularly advantageous for users who need to position their devices further from power outlets or want to create a more organized workspace. Additionally, the iRasptek’s design includes an automatic limit increase feature, allowing it to communicate more effectively with the Raspberry Pi 5 to optimize power delivery.

Safety Features

Safety features are crucial in power supplies to protect both the device and the user. The GeeekPi power supply boasts multiple protection functions, including over-voltage, under-voltage, over-temperature, over-current, and short circuit protection. This range of safety features ensures a stable and secure operation for your Raspberry Pi. In comparison, while the iRasptek doesn't explicitly list similar safety features, it has undergone extensive compliance testing to meet various international standards. Users should consider the importance of these safety measures when selecting a power supply, especially for prolonged use.

User Convenience

User convenience is a notable aspect of both power supplies. The GeeekPi includes an ON/OFF switch, allowing users to easily power the Raspberry Pi on and off without needing to unplug the device. This feature can enhance user experience by providing quick access to power management. Conversely, the iRasptek does not mention such a switch, which may require users to unplug the device to turn it off. For those who prioritize convenience and ease of use, the presence of an ON/OFF switch in the GeeekPi could be a significant advantage.

Brand Reputation and Support

Brand reputation and customer support can influence purchasing decisions. GeeekPi is known for producing reliable accessories specifically designed for Raspberry Pi products, which may assure users of its quality and performance. The iRasptek brand has also established a presence in the market, particularly with its focus on advanced power delivery features. However, potential buyers should consider the availability of customer support and resources for troubleshooting, which can enhance their overall satisfaction with the product. The iRasptek offers a customer support contact for inquiries, which may be beneficial for users needing assistance.

Which should you buy?

Choosing between the GeeekPi 18W 5V 3.6A Power Supply and the iRasptek 27W USB-C Power Supply ultimately depends on your specific needs. If you are looking for a cost-effective solution for the Raspberry Pi 4 and appreciate features like an ON/OFF switch, the GeeekPi is a solid choice. However, if you require higher power output for the Raspberry Pi 5 and its peripherals, and are willing to invest a bit more, the iRasptek offers superior performance with its advanced capabilities. Each power supply has its strengths, so consider your device compatibility and power needs before making a decision.
