There are two USB-A ports on the front of the device. The ports have iSmart 2.0 technology that lets the gear know what's plugged in and how to deliver the fastest charging speeds. While the device isn't compatible with Quick Charge or anything like that, it'll still be a lot faster than your average power adapter, like the 5W version that comes with most iPhones.

Plus, the device itself can recharge pretty quickly despite its size. It will recharge twice as fast as previous generations and be completely ready to go in just nine to ten hours. It is specifically designed so the three ports are all next to each other to help minimize wire tangling, too.

RAVPower has built-in safety features. It will protect your devices from things like over-charging, overheating, voltage surges, and more. Users give it 4.7 stars out of 5 based on 328 reviews.
