While external batteries with AC power and USB-C PD fast-charging ports are becoming more commonplace, mophie's new powerstation AC sets itself apart with a 100-watt output, enough juice to deliver 15 hours of extra battery life for a MacBook. With a 22,000 mAh battery, the powerstation AC also provides additional battery life for most USB-C devices, including tablets, smartphones and more. There's also an output for traditional USB-A devices. On the design front, a premium fabric wrap protects against scratches and delivers a soft hand feel.
