These chargers are convenient for reducing cable clutter and simplifying the charging process, especially for users who own multiple wireless charging-compatible devices. They are popular accessories for desks, bedside tables, or other areas where devices are frequently charged. 

The most common setup for a 3-in-1 wireless charger includes a pad for smartphones that support wireless charging (such as iPhones or Android devices with Qi wireless charging capabilities), a stand or dock for charging a smartwatch (like an Apple Watch or a Samsung Galaxy Watch), and a smaller area for charging wireless earbuds (like AirPods or Galaxy Buds).

These chargers are often designed to charge smartphones, smartwatches, and wireless earbuds, all without the need for separate cables. They typically feature multiple charging pads or coils to accommodate the different devices.
