MotionSense faucets offer hands-free use that is both convenient and helpful in controlling the spread of germs. Ensure your MotionSense faucet stays powered and operational with the Moen AC Adapter Kit. Use the AC power adapter in this kit to replace the battery pack that is included with the MotionSense unit to supply power to your MotionSense faucet. This AC Adapter Kit is easy to use and install. Simply connect the AC adapter and the battery pack (included with your kitchen faucet with MotionSense) to the Power Splitter. Connect the barrel plug of the Power Splitter to your MotionSense unit and then plug the AC adapter into a nearby wall outlet.
