A power extension board with USB ports and safety sockets is a convenient accessory for managing multiple devices while providing additional power outlets and USB charging ports. Here’s how it typically works and what to look for in a good quality one:
1. Functionality: These extension boards typically come with multiple power sockets (usually 3 or more) and integrated USB ports (often 2 or more). They are designed to allow you to plug in standard electrical devices as well as charge USB-powered devices like smartphones, tablets, and other gadgets directly from the extension board.
2. Safety Features: Look for extension boards that offer surge protection, overload protection, and possibly overcurrent protection. Surge protection helps safeguard your devices from voltage spikes, while overload protection prevents overheating due to excessive power draw.
3. Length and Cord Quality: A 3-meter length cord gives you flexibility in placing the extension board where it’s needed without being restricted by proximity to the power outlet. Ensure the cord is of good quality to handle the electrical load and is durable for long-term use.
4. Build Quality: Opt for extension boards made from fire-resistant materials and with well-insulated sockets to reduce the risk of electrical hazards.
5. USB Port Specifications: Check the output ratings of the USB ports (e.g., 5V/2.4A) to ensure they can charge your devices at a reasonable speed. Some higher-end models may support fast charging protocols like Qualcomm Quick Charge or USB Power Delivery.
6. Color and Design: While color is often a matter of personal preference, consider the overall design to ensure it fits aesthetically and functionally in your space.
Popular brands like Belkin, TP-Link, and Anker offer reliable extension boards with USB ports and safety features. When using the extension board, plug it directly into a wall outlet and avoid overloading it with high-power appliances to maintain safety and efficiency.
