iUniker GaN PD 27W 5.1V 5A 27W PD Power Supply USB-C for Raspberry Pi 5 vs PiSugar 3 Portable 1200 mAh UPS Lithium Battery Pwnagotchi Power Module for Rasp

Overview of the iUniker GaN PD 27W Power Supply and PiSugar 3

The iUniker GaN PD 27W power supply is a dedicated charging solution for Raspberry Pi devices, while the PiSugar 3 serves as a portable uninterruptible power supply (UPS). At £13.79, the iUniker power supply is significantly less expensive than the PiSugar 3, which retails at £39.99. Each product has its unique strengths, making them suitable for different use cases within the Raspberry Pi ecosystem.

Design and Build Quality

The iUniker power supply utilises GaN technology, allowing for a compact design that doesn’t compromise on power output. It operates at a voltage of 5.1V and can provide up to 5A, ensuring efficient charging and minimal heat generation. In contrast, the PiSugar 3 employs a pogo pin design for easy connectivity with Raspberry Pi, thus preserving GPIO availability. This thoughtful design enhances usability for various projects. The build quality of both products appears robust, but the iUniker focuses on stationary power, whereas the PiSugar 3 is built for portability.

Features and Capabilities

The iUniker power supply boasts multiple output options, including 5.1V/5A and 9V/3A, catering to different power needs. It also features overvoltage, overcurrent, and short circuit protection, ensuring the safety of your devices. On the other hand, the PiSugar 3 is designed specifically as a UPS, featuring a 1200 mAh lithium battery that allows for uninterrupted power, even during outages. This makes it indispensable for projects requiring constant power. The PiSugar 3 also includes advanced features like a software watchdog function, which can restart the Raspberry Pi if it crashes, adding a layer of reliability not found in the iUniker power supply.

Compatibility

The iUniker GaN power supply is compatible with both the Raspberry Pi 5 4GB and 8GB models, making it a versatile choice for users of the latest Raspberry Pi technology. Meanwhile, the PiSugar 3 is compatible with Raspberry Pi 3B, 3B+, and 4B models, ensuring broad usability across earlier Raspberry Pi versions. While both products target Raspberry Pi users, the iUniker power supply is specifically designed for the latest iteration, while the PiSugar 3 offers backward compatibility, making it suitable for a wider range of devices.

Performance and Efficiency

The iUniker power supply operates efficiently with an input range of 100 to 240V AC and a maximum output of 27W. This means it can handle various power conditions, making it a reliable choice for home use. The PiSugar 3, on the other hand, provides a maximum input of 5V and 3A, which is sufficient for powering Raspberry Pi devices while offering the advantage of portability. Users seeking a stationary power source may find the iUniker more beneficial, whereas those requiring mobility and battery backup would prefer the PiSugar 3.

Safety Features

Safety is a critical consideration for both products, with the iUniker power supply featuring multiple protection mechanisms, including overvoltage and overcurrent safeguards. This ensures that connected devices are protected from electrical faults. In comparison, the PiSugar 3 boasts extensive hardware protection, limiting battery voltage to nearly 80% and implementing quadruple overvoltage protections. This proactive approach to safety can significantly extend the lifespan of the battery and improve system reliability, making the PiSugar 3 a more secure option for long-term projects.

User Experience

Users of the iUniker power supply can expect a straightforward experience as it simply plugs into a wall socket and connects via USB-C to the Raspberry Pi. The short 120mm cable may limit placement options, but its simplicity is a plus for many. Conversely, the PiSugar 3's unique installation via pogo pins and I2C communication offers a more integrated experience, although it may require more setup and understanding of its features. The additional functionalities, including soft shutdown and remote control via WebUI, provide a rich user experience for those willing to invest the time.

Which should you buy?

The choice between the iUniker GaN PD 27W power supply and the PiSugar 3 ultimately depends on your specific needs. If you require a reliable, efficient power supply for the latest Raspberry Pi models and prefer a straightforward plug-and-play solution, the iUniker at £13.79 is an excellent choice. However, if you need a portable UPS solution that offers advanced safety features and can keep your Raspberry Pi running during power interruptions, the PiSugar 3, though pricier at £39.99, is the better option. Each product excels in its intended role, so consider your use case carefully before making a decision.
