5V 4A Power Supply Adapter - AC 100-240V to DC 5V/4A 20W Charger DC 5.5mm x 2.5m vs HKY 54V Power Supply AC/DC Adapter for Ubiquiti Network Ultra 60W USW-Ultra-60W

Overview of the Products

In this comparison, we will examine the 5V 4A Power Supply Adapter by COLM and the HKY 54V Power Supply AC/DC Adapter. Both products serve distinct purposes and are designed for different devices, with the former priced at £14.96 and the latter at £23.99. Understanding their unique features and specifications is crucial for making an informed decision based on your power supply needs.

Input Voltage and Compatibility

The COLM power supply adapter accommodates a universal input voltage range of AC 100-240V, making it suitable for use worldwide. It outputs a DC voltage of 5V at 4A, providing a total power output of 20W. This makes it an excellent choice for devices like the Odroid XU4 and Jetson Nano. In contrast, the HKY adapter also supports an input voltage range of 100-240V but delivers a higher output of 54V at 1.1A, reaching a maximum power of 60W. It is specifically designed for Ubiquiti Network devices, such as the USW-Ultra-60W switch. If your device requires 54V, the HKY adapter stands out as the only option between the two.

Design and Build Quality

The build quality of both power supplies is commendable, with the COLM adapter featuring certifications from CE, FCC, and PSE, which emphasise its safety features, including overload and short circuit protection. The HKY power supply, on the other hand, boasts multiple certifications, including UKCA, CE, ROHS, and UL, ensuring it meets various safety standards. The COLM adapter comes with a DC interface size of 5.5mm x 2.5mm, which is compatible with 5.5mm x 2.1mm plugs, while the HKY’s specifications are tailored to meet the requirements of Ubiquiti devices. The choice of adapter may depend on the specific requirements of your equipment.

Power Output and Usage

The COLM power supply's output of 5V at 4A is suitable for low-power devices, making it a perfect replacement for older adapters that may have provided lower amperage, such as 2A or 3A. However, if you require a more powerful solution, the HKY adapter’s 54V output is designed for high-demand devices, offering 60W of power. This is particularly important for users with network equipment needing stable and high-capacity power sources. When considering power output, the intended use of the device will significantly influence which adapter is most appropriate.

Safety Features

Safety is paramount in power supply design, and both the COLM and HKY adapters incorporate essential protection features. The COLM adapter includes automatic overload cut-off, over voltage cut-off, and thermal cut-off, ensuring device safety during operation. Similarly, the HKY unit features over voltage protection (OVP), over current protection (OCP), and short circuit protection (SCP), providing reassurance of its reliability. The presence of these safety features enhances the overall user experience, making both products trustworthy choices.

Length of Power Cords

The length of the power cords can impact convenience and usability. The COLM adapter includes a DC cable length of about 3.6FT (approximately 110 cm) and a power cord of about 3.9FT (about 120 cm). This length provides adequate reach for most setups without being cumbersome. In comparison, the HKY power supply’s cord length specifics are not provided, but it is designed for direct connection to Ubiquiti devices, which may imply a more tailored fit for specific installations. If cord length is a decisive factor for your setup, the COLM adapter offers clearer specifications.

Price and Value for Money

When comparing prices, the COLM adapter is priced at £14.96, making it a budget-friendly option for users needing a simple 5V power supply. Conversely, the HKY adapter costs £23.99, reflecting its higher power output and specialised compatibility with Ubiquiti devices. While the COLM product offers excellent value for low-power applications, the HKY’s price is justified when considering its capabilities in high-demand networking environments. Your budget and specific needs will guide the choice of which product offers better value for your situation.

Customer Support and Warranty

Customer support and warranty can be critical aspects of the purchasing decision. The COLM adapter comes with a commitment to quality after-sales support, encouraging users to reach out for any inquiries. Although the HKY product’s customer support details are not specified, its extensive safety certifications suggest a reliable brand reputation. Knowing that you can receive assistance post-purchase is an important consideration, particularly for those new to using power supplies.

Which should you buy?

Ultimately, the decision between the COLM 5V 4A Power Supply Adapter and the HKY 54V Power Supply AC/DC Adapter hinges on your specific needs. If you require a power supply for low-power devices, the COLM adapter is an economical choice with solid safety features and sufficient output. However, for users with Ubiquiti networking equipment needing higher power levels, the HKY adapter is the more suitable option, despite its higher price. Assess your device requirements and budget before making a choice, as both products cater to different segments of the power supply market.
