When you place the Samsung Trio Wireless Charger 15W Black on your nightstand, your smartphone, Galaxy Watch, and earbuds are fully charged every morning. Your Samsung Galaxy S25 only charges wirelessly with a magnetic case. This charger is suitable for all Samsung Watches from the Galaxy Watch 3, including the Watch Active and Active 2. Older models like the first generation Galaxy Watch aren't supported. Other smartwatches like the Apple Watch don't fit. There are 2 charging spots for smartphones or earbuds. In addition to your smartphone, you can charge your Galaxy Buds or your partner's smartphone. This charger supports wireless fast charging for both Samsung and Apple. As a result, devices charge about 1.5 times faster compared to a regular charger. With a magnetic case, you can attach your Samsung S25 extra sturdily on the wireless charger. The advantage is that you always place your device well on the charger. This way, you prevent your device from not charging or charging slowly and is still empty. Samsung smartphones charge faster with this charger than the regular chargers, but not at maximum speed.
