The official Apple 12W power adapter just has one USB port, but if you need to charge two or three mobile devices, maybe you need a charging station or a 3-port travel wall charger such as the following one.
This is a practical wall charger designed to offer you an easy way to charge up to three mobile devices at the same time. As we can see from the images, the wall charger features portable, ergonomic design, and comes with three built-in USB ports, one for Samsung Galaxy Tab and Galaxy Note Android tablets, other two below for iPad, iPhone and other USB-enabled mobile devices so you can easily charge your Android phone, tablet and iOS devices at home, in office or hotel. Moreover, the prong is foldable for easy to carry.
The 3-port wall travel charger is priced at $12.99 USD. If you’re interested, jump to USBfever online store for more details. Additionally, if you need other options you might like to check XE4400 wall charger and more via “wall charger” tag.
