You can charge your smartphone with an Anker charger and a charging cable. Quickly charge your Android smartphone via Quick Charge with a rectangular USB-A port. That way, your smartphone charges 1.5 to 2 times as fast as with a standard charger. You can also easily charge smartphones with a different fast charge protocol, like iPhones, but not at the maximum speed. You need a Power Delivery Anker charger for that with an oval USB-C port. Devices without fast charging, like e-readers or headphones, will get exactly as much power as they can handle. It's also possible to charge your smartphone, e-reader, earbuds, and smartwatch at the same time with multiple ports while you're on vacation.
