Pyramid Desktop Bench Power Supply vs iRasptek 27W USB-C Power Supply with PD for Raspberry Pi 5（5.1V/5A）

Overview of Pyramid Desktop Bench Power Supply

The Pyramid Desktop Bench Power Supply offers a robust solution for powering various electronic devices, while the iRasptek 27W USB-C Power Supply is specifically tailored for the Raspberry Pi 5 and its peripherals. Priced at C$70.78, the Pyramid power supply is designed for versatility and reliability, making it suitable for multiple applications such as hobbyist projects and professional setups. On the other hand, the iRasptek power supply, priced at C$21.99, is focused on providing optimal power delivery for Raspberry Pi 5 users, particularly when connecting high-power peripherals.

Power Output Comparison

The Pyramid Desktop Bench Power Supply provides a significant output of 13.8V DC with a maximum current of 12 amps, allowing for substantial power delivery across a variety of devices. This makes it ideal for users needing a reliable source of power for testing devices or running multiple components simultaneously. In contrast, the iRasptek 27W USB-C Power Supply offers multiple output options, including 5.1V/5A, 9V/3A, and others, with a maximum output of 27W. While the iRasptek power supply's output is lower in voltage, its capability to support USB Power Delivery makes it versatile for devices that require varying power levels.

Charging Capabilities

The Pyramid power supply features a USB charging port alongside universal screw terminals, making it adaptable for powering various electronic devices directly. This dual functionality allows users to charge devices like cellular phones and radios while powering other equipment simultaneously. Conversely, the iRasptek power supply is specifically designed for the Raspberry Pi 5, enabling it to automatically increase the USB current limit from 600mA to 1.6A when required. This feature is particularly beneficial for users who need to drive power-hungry peripherals connected to the Raspberry Pi.

Design and Usability

The Pyramid Desktop Bench Power Supply boasts a rugged and durable housing ideal for benchtop or desktop use. It includes a built-in cooling fan to prevent overheating during prolonged use, ensuring a stable operation. The simple plug-in operation and an LED backlit ON/OFF switch enhance user convenience. In comparison, the iRasptek power supply is designed with a compact form factor, making it easy to integrate into setups without taking up much space. Its 1.5m cable provides flexibility in positioning, though it lacks the added features of cooling fans or advanced controls found in the Pyramid model.

Safety Features

Safety is a critical aspect of both power supplies. The Pyramid Desktop Bench Power Supply incorporates built-in electronic overload and short-circuit protection, which is essential for safeguarding both the operator and connected devices. This feature ensures that in the event of an electrical fault, the power supply will prevent damage. On the other hand, while the iRasptek power supply does not explicitly mention safety features, it has undergone extensive compliance testing, ensuring that it meets various regional and international standards, which can also provide peace of mind for users.

Application Versatility

The Pyramid power supply is highly versatile, suitable for a range of applications including powering cellular phones, CB radios, and even testing electronic circuits. Its ability to operate with various devices makes it a valuable tool for both professionals and hobbyists. Meanwhile, the iRasptek power supply is specifically crafted for the Raspberry Pi 5, excelling in scenarios where users need to power high-demand peripherals like hard drives and SSDs. This targeted design makes it less versatile overall but highly effective within its intended use case.

Pricing and Value

With a current price of C$70.78, the Pyramid Desktop Bench Power Supply is a more significant investment compared to the iRasptek’s price of C$21.99. This price difference reflects the broader application scope and higher power output capabilities of the Pyramid model. However, for Raspberry Pi 5 users specifically, the iRasptek offers excellent value, providing the necessary features to enhance the performance of the Raspberry Pi at a fraction of the price. Users must consider their specific needs when evaluating the value offered by each power supply.

Which should you buy?

Choosing between the Pyramid Desktop Bench Power Supply and the iRasptek 27W USB-C Power Supply ultimately depends on your specific requirements. If you need a versatile power supply for a wide range of electronics, the Pyramid model stands out with its robust output, multiple connection options, and safety features. However, if your primary focus is on powering the Raspberry Pi 5 and its peripherals, the iRasptek power supply offers tailored functionality at a lower price point. Evaluate your use case carefully to make the best decision for your powering needs.
