You can simultaneously charge two devices with this Anker Adapter with two USB-A ports. That way, your power sockets aren't constantly occupied. Both USB-A ports have a total power output of 12 watts. That's enough to also charge devices with a large battery, such as tablets. Does your smartphone or tablet support some kind of fast charging, like Quick Charge or Power Delivery? If so, you require a separate, faster charger. This charger does work with with those devices, but it can't charge as quickly as a fast charger. Because smartwatches and e-readers don't support fast charging, this charger is very suitable for these kinds of devices.
