The charging Butler allows you to plug in all the batteries at the end of the day and go to rest without having to replace them halfway through. There are two main differences between the premium and regular versions. One is that the premium version supports both the Phantom 4's 100W charger and car charger, while the regular version only supports the Mavic's built-in 50W charger and car charger.
