The E2 Power Pack from Enouvation offers you the ability to cut the cord on your power motion furniture or lifestyle base. This gives you the ability to float a power motion piece of furniture without having to see those unsightly, industrial cords. The E2 will give your Sofa with Power Headrests approximately 200 cycles and Recliner 400 cycles before having to recharge. Enouvation Power Packs are tested to multiple UL standards and certified, having gone through rigorous testing. They are the most efficient battery in the marketplace with twice the power, half the size. All Power Packs have an LED Power Indicator that shows the level of power in the tank and an interactive power alert when the battery runs low. Each Power Pack comes with its own charger in box.
