Stairlifts are powered by electricity. Many versions these days come fitted with a battery back-up that is upon continuous charge. This means that the stair lift can be used even in a power cut. Even though power-cuts are not common incidences, for stair lift users the ability to get up the stairs is not something you can do devoid of. Bathrooms and bedrooms tend to be located upstairs and virtually any interruption in the power can cause an uncomfortable wait for the user. A hand control, integral termes conseill├ęs or buttons are used to walk around the lift up and down the steps. If for some reason you are not on the same level as the lift up - it can be called applying controls at either the top or bottom of the staircase - a great feature to make sure you can never be stranded.
