The power bank for the switch is truly needed for long game play. It is lightweight, fits snug, and adds features to the switch (stand, x2 game storage, and battery life). The design quality is perfect and allows for air flow to properly circulate throughout the unit. Setup takes less than 5 minutes and the unit charges quickly. The only down side is that you have to use your existing usb cable to charge the unit. Overall, this is great addition to any switch and needed for long portable game play.
