GeeekPi USB-C Power Supply UK Plug for Raspberry Pi 4 With On/Off Switch vs iUniker GaN PD 27W 5.1V 5A 27W PD Power Supply USB-C for Raspberry Pi 5

Overview of the Products

The GeeekPi USB-C Power Supply and the iUniker GaN PD Power Supply both offer unique features tailored for Raspberry Pi devices, but they cater to different models. The GeeekPi is specifically designed for the Raspberry Pi 4, while the iUniker is compatible with the newer Raspberry Pi 5. With prices set at £11.99 and £13.79 respectively, there are notable differences in functionality and technology that may influence your purchasing decision.

Compatibility

Compatibility is a key factor when choosing a power supply for your Raspberry Pi. The GeeekPi USB-C Power Supply is designed for the Raspberry Pi 4 across all its variants—1GB, 2GB, 4GB, and 8GB. It also includes a USB-C to Micro USB adapter, making it compatible with Raspberry Pi 3B and 3B+, as well as Orange Pi models. In contrast, the iUniker GaN PD Power Supply is exclusive to the Raspberry Pi 5, supporting both 4GB and 8GB versions. If you own a Raspberry Pi 4, the GeeekPi is the clear choice; however, the iUniker is ideal for those looking to power the latest Raspberry Pi model.

Power Output

When it comes to power output, there is a significant difference between the two products. The GeeekPi offers a consistent output of 5V at 3.6A, translating to an 18W power supply. This is designed to ensure stable performance for the Raspberry Pi 4. On the other hand, the iUniker boasts a more versatile power output with multiple options, including 5.1V at 5A, which provides a maximum of 27W. This additional power could be advantageous for demanding applications on the Raspberry Pi 5, making the iUniker more suitable if you require higher performance.

Design and Usability

The design and usability of a power supply can greatly affect user experience. The GeeekPi features an ON/OFF switch, allowing users to easily control power without the hassle of unplugging the device. This can be particularly convenient for users who frequently turn their Raspberry Pi on and off. Meanwhile, the iUniker power supply utilises GaN technology, making it smaller and cooler to operate without sacrificing power output. While the iUniker lacks a physical switch, its compact design could be more appealing for users with limited space or those who prefer a minimalist setup.

Safety Features

Safety is paramount when using electronic devices, and both power supplies come equipped with protective features. The GeeekPi includes comprehensive protection against over-current, short-circuit, over-voltage, low-voltage, over-temperature, and electrostatic issues. This ensures safe and reliable usage of your Raspberry Pi. Similarly, the iUniker also offers over-voltage, over-current, and short-circuit protection, providing peace of mind to users. While both products have strong safety features, the GeeekPi's extensive list may give it an edge for those prioritising safety above all.

Cable Length and Quality

The length and quality of the power cable can influence how convenient a power supply is to use. The GeeekPi comes with a 120cm cable, allowing for ample distance between the power source and the Raspberry Pi, which is beneficial in larger setups. The iUniker also features a similarly long 120mm cable, ensuring flexibility in positioning. Both cables are constructed using quality materials, but the GeeekPi highlights the use of high-quality copper wire for better conductivity and stable transmission, which may enhance performance compared to the standard cables.

Certification and Professional Standards

Certification can be an important aspect for consumers regarding quality assurance. The GeeekPi power supply holds both UKCA and RoHS certifications, indicating that it meets specific safety and environmental standards for electronic devices in the UK. The iUniker, while not explicitly stating certifications in the provided data, is implied to meet necessary safety standards by its inclusion of protective features. For users who value certified products, the GeeekPi may offer an added layer of trustworthiness.

Price Comparison

When considering budget, the price difference between the two power supplies is noteworthy. The GeeekPi is priced at £11.99, making it a more cost-effective option for those using a Raspberry Pi 4. In contrast, the iUniker is available for £13.79, reflecting its advanced technology and higher power output capabilities. This £1.80 price difference could be justified for users who require the additional power and features of the iUniker, especially if they are using a Raspberry Pi 5.

Which should you buy?

Deciding between the GeeekPi USB-C Power Supply and the iUniker GaN PD Power Supply ultimately depends on your specific needs. If you own a Raspberry Pi 4 and prefer a power supply with an ON/OFF switch, comprehensive safety features, and a lower price, the GeeekPi is the better choice. However, if you are using a Raspberry Pi 5 and require higher power output with the latest technology, the iUniker is worth the extra £1.80. Both products have their merits, so align your choice with your Raspberry Pi model and usage requirements.
