If you're looking to charge multiple devices at a time, quickly, this is for you. Anker, a popular accessory maker that we use often has a good wall charger with two USB ports.
This model has a high 18w of power output and is even Quick Charge 3.0 certified on both ports. Meaning it will work with the Galaxy S9 and almost any other Android smartphone. The Anker 18w Quick Charge 3.0 certified charger will power up your device up to 75% faster than typical chargers. And since it has two USB ports, you can charge two devices at the same time.
