We Get Around Network Founder Dan Smigrod recommends getting a portable charger for your iPad and smartphone and a car inverter (12V DC--> 110V AC) to charge your laptop and Matterport Pro2 3D Camera. While the Matterport Camera battery lasts 8-12 hours, you will want to continuously charge your iPad and smartphone while scanning so that both last the entire day too. Get a portable charger with at least two ports to charge. Dan prefers one with four ports for charging 4 devices simultaneously. Get one that fits in your back pocket. The inverter is great for charging the Camera while driving as well as the iPad and a smartphone.
