Does it charge a phone and a watch at the same time?

Yes. It has a phone pad and a foldable watch charger on one base, so both can sit on the dock together. The detachable board lets you separate the two sections.

Do I need to buy a power adapter?

Yes. The box has the station and a 1.1m USB-C cable only. Use a USB-C wall charger rated for 9V output to get the full 3.1A charging current.

Will it charge through a phone case?

Wireless charging generally works through thin cases, but thick, metal or magnetic cases can block it. Remove bulky cases if the phone does not start charging.

Is it good for travel?

It is compact and the watch charger folds down, so it packs easily. You still need to carry a USB-C power brick and cable.

Does it work with earbuds?

No. Despite the 3-in-1 name, the dock covers a phone and a smartwatch only. Wireless earbuds need a separate charger.

What phones and watches does it support?

Any phone and smartwatch that charge on the Qi wireless standard. Check that your watch supports Qi charging, since some watch brands use proprietary chargers.
