The Samsung Galaxy S21 FE doesn't come with a charger adapter, only a cable. With the right Samsung S21 FE charger adapter, you can charge your smartphone extra fast. After half an hour of charging with a 25W Samsung Super Fast Charging charger, your empty battery is 60% charged already. With other S21 FE fast chargers, you get to around 40% in the same time. Not using a fast charger? You'll get just under 20% in half an hour of charging. As your S21 FE already comes with a cable, a separate charger adapter is all you need. Choose a charger adapter with cable if you want to have a spare cable. Consider getting a nylon or kevlar one, because they last extra long.
