If you need a little more than the usual battery pack, myCharge's rugged new Adventure Extreme will have more than enough power for all your devices and then some. With 65 Watts of power and an AC outlet you can plug your laptop straight into the battery pack while also charging regular USB-based devices and new devices that feature a USB-C connector. It also features its own dedicated display that gives you a battery percentage, temperature, and an on/off status for every port.
Incase's IconConnected Power Sleeve hides an extra battery for your MacBook Pro
