Power Bar is a charging rod for motorised cellular shades. In contrast to present solutions, it eliminates the need for cables and the difficult replacement of batteries. Each window covering includes a dedicated docking station to easily attach the Power Bar. The slim, elegant profile of the rod means its connection to the shade is secure, even if it swings back and forth. It is equipped with a small display that reliably shows the current rechargeable battery level of shade and bar respectively.
