Power Options for Motorized Cellular Shades

What's the best option for powering your motorized cellular shades? Well, that depends! The information below is intended to help guide you towards the best option for your situation. As always, feel free to contact us if you have any questions!


External Mount Battery Pack

External Battery Pack for Powering Large Motorized Cellular Window Shades

The external-mount rechargeable lithium battery pack measures nearly 10 inches long. As a result, it carries plenty of capacity and power for infrequent charging and dependable operation. While this battery could be placed inside the headrail in some applications (for example, with an outside mount shade), it would protrude approximately 1/2 inch above the top of the headrail. In most cases, the battery would be mounted outside the headrail. If you have at least 1 3/4 inches between the back of your headrail and the window or framing, the battery can be hung inconspicuously on the back side of the headrail. Otherwise, it can be mounted with screws or double-sided tape wherever you decide is best (extension cables may be necessary).


  • Energy effiicent
  • No wires running to an outlet, except when charging
  • Operates when there's no electricty (i.e. during a power outage)
  • Can be combined with a solar charger for maximum energy efficiency


  • Cannot be hidden in some cases
  • Requires periodic, but infrequent, charging


Plug-In Transformer (Power Supply)

If you don't want to worry about charging your battery pack and you don't have the right configuration for a solar charger, you can always plug your shade right into the nearest power outlet with our plug-in transformer. It's simple, reliable, and power consumption is minimal since shades are not operated continuously.


  • Set it and forget it - no need to worry about charging
  • Plenty of power for any size shade


  • Wire from motor to outlet may be visible
  • Not as energy efficient as battery options
  • You lose the ability to operate your shades during a power outage
