Closed, it is just a speaker
WCH-102 was designed to disappear into a desk. Closed, it is a short cylinder with a fabric grille and light ring — no visible coils, no plastic arms folded out to advertise themselves. The charging hardware only appears when you lift the lid.
Under that lid sits a magnetic pad that tilts up to hold the phone facing you, which is the difference between a charger you tolerate and one that is useful for a video call. Earbuds rest in the recess beside it, a watch wraps the side rail, and all three coils run together for 22W total.
The speaker is not an afterthought. A φ52 mm driver and 1800 mAh cell give 4–6 hours of playback with the same warm ring pulsing on the beat, and there is FM radio for markets where that still matters. Recharge is USB-C at 5V/3A or 9V/3A with PD and QC support.
OEM covers the usual ground and a little more: shell colour and finish, the behaviour of the light ring, logo print, gift-box artwork, insert tray and manual language.
