The E6 Power Pack from Enouvation offers you the ability to go cordless on Power Motion furniture. This means you can float a Power Motion piece of furniture without having to see those unsightly, industrial cords. Enouvation Power Packs are tested to multiple UL standards and certified, having gone through rigorous testing. Each Power Pack comes with its own charger in box. The frequency with which your Power Pack will need to be recharged varies greatly on the amount of use. Patents pending.
