The GAN PowerPod (UI) is a charging station for your GAN Smart Cube! This one is made to fit the most recent generation of GAN Smart Cubes (GAN12 UI Free Play and GAN Mini UI Free Play). It holds a charge like a backup battery. You can charge your cube from this power pod 7-8 times before charging it again! You're good to go as long as you have the power pod with you!
