The average stair lift draws about 250 watts . This is in line with what’s expected, simply because stair lifts don’t have to accelerate hard, and the force required to lift a 220-pound human 10 feet in the air is about 3 kilojoules. Wattage is simply a measure of the number of joules consumed per second.
