You know a picture adds 10lbs lol! Keep in mind it was extreme zoom in. In person it doesn't look that bad, still slim and pocketable. This is definitely intended for power users who play games or watch movies, or if you are on a trip and will be away from power source for awhile. Imagine a scenario where you spend 1-2 hours on a train commuting to work and play videos or watch YT before you get to work. There you no longer have a fresh battery and might not have enough charge for the trip back. Might not be everyone's cup of tea, but some might benefit or use it in specific situation.
