The Galaxy Watch 4 and Galaxy Watch 4 Classic are charged wirelessly. The company bundles a magnetic wireless charger in the box, so you don’t have to worry about finding a compatible charger. Unfortunately, the Galaxy Watch 4 series doesn’t fully support the Qi wireless charging standard. This drastically reduces the number of charger options for the two smartwatches. So if you’re looking for a Galaxy Watch 4 charger, the official Samsung ones are your best bet.
