Because all of our units plug into common household outlets, they need no special wiring. Stairlifts are energy efficient, costing just pennies to run. And you won’t need to fear that an electrical storm or some other problem that cuts your power will leave you stranded. Hidden on the back of the rail is a narrow copper strip that constantly trickle-charges the battery, so it is always full. This virtually eliminates the biggest cause of service calls (flat batteries) for the more basic stairlifts you may see advertised. The battery charger is a white box plugged into a standard outlet. In the event of a power outage the stairlift will typically give you 15-20 roundtrips on battery power alone.
