To begin using the CUKTECH NO.20, ensure you are using high-quality USB-C cables rated for 5A/100W or higher to take full advantage of the 140W output capability. The device is widely compatible with most USB-powered electronics, including laptops, tablets, phones, and handheld gaming consoles. For maintenance, keep the ports free of debris and store the unit in a cool, dry environment.
