It's okay. The original Switch dock can charge the Switch console and connect the TV or monitor at the same time, so you can play while charging. When the Switch console is connected to the base, the USB-C port on the base provides power to the console while transmitting image and audio signals to the TV or monitor, allowing you to play happily on the big screen.
The dock also has multiple USB ports that can be plugged into other gamepads or other USB devices. In short, the original Switch base is a very practical gaming accessory that can improve the gaming experience of the Switch console, so that you can enjoy the fun of the game more freely.
Most of the original Switch bases support charging while playing, which means you can use a controller to play games while the base is connected to a power source. This ensures that the game will not be interrupted due to battery exhaustion during a long game. Note, however, that in order to ensure stability and safety, it is recommended to use the original charger and base. Using non-original chargers and bases can cause problems during charging.
