Stairlifts are run by electricity. Many styles these days come fitted with a battery back-up that is in continuous charge. This means that the stair lift can be used also in a power cut. Though power-cuts are not common incidences, for stair lift users the ability to get up the stairs is without question not something you can do with no. Bathrooms and bedrooms are frequently located upstairs and any kind of interruption in the power can result in an uncomfortable wait for the user. A hand control, integral joystick or buttons are used to continue the lift up and down the stairs.
