The Circuit Playground Express can stay connected via USB power from either a wall adapter or computer's hub. This allows the board to stay lit as long as you want (nightlight mode anyone?). The Dragon flame has a cutaway to accommodate for a USB cable. A LiPo battery is optional and can be tucked in between the Circuit Playground Express and the 3D printed flame.
