These two get compared on price and range, which is the wrong comparison. They are different categories of equipment for different situations, and the choice usually makes itself once you know what actually separates them.
The short version
A mobility scooter is transport. It extends how far somebody can go, for somebody who walks reasonably well over short distances but cannot manage a shop, a car park or a market.
A power wheelchair is a seating system with a motor. It is for somebody who will be in it for much of the day, and the seat is the important part.
Three questions that decide it
How long will they sit in it? Under an hour at a time, a scooter is usually fine. Several hours a day and the seating matters more than anything else, which means a chair.
Can they walk to it and transfer onto it? A scooter requires standing, stepping over, sitting and steering with both hands. That is more function than people assume.
Where will it be used? Scooters have a wide turning circle. Inside an ordinary house with ordinary doorways, most are unusable. A power chair turns in its own length.
Why seating decides so much
A scooter seat is a seat. A power chair seat is a clinical assembly: cushion, back support, lateral supports, tilt, sometimes recline. For somebody who sits for hours, that assembly is what prevents pressure injury and what holds posture over time.
This is the part sold badly most often. Our ATPs and CRTS specify seating with the treating clinical team where there is one, and the reason is simple: equipment chosen without measuring the person is the equipment that ends up abandoned in a hallway.
Transporting it
Ask this before you buy, not after. A folding or travel scooter goes in a boot. A full-size scooter or a power chair needs a vehicle lift or a conversion.
The most common expensive mistake in this category is buying the chair and then discovering it cannot leave the house. Our vehicle page covers the lifts that solve it.
What Medicare covers
This is one area where the answer is more encouraging than with stairlifts. Power wheelchairs and scooters can fall within Medicare’s durable medical equipment category, unlike anything attached to the house.
Coverage turns on medical necessity and documentation, and it comes from your physician rather than from us. We do not yet bill health insurance, and we say so early rather than late.
Batteries
Consumables rather than failures. Typically a year or two of daily use. Stated ranges are measured under favorable conditions, so treat them as a ceiling rather than an expectation, and expect less in the cold and on hills.
Try before you buy
Most of this equipment is bought from a photograph. It does not have to be. Sit in it, drive it, turn it in a space the size of your hallway. Any decent supplier should let you, and ours is walk-in during showroom hours with personal consultations available by appointment.
When neither is the answer
Frequently the honest answer is a rollator. For somebody who walks but tires, a well-fitted rollator with a seat does more for daily life than a scooter that lives in a garage.
Rollators, walkers, transport chairs and cushions ship free from our online shop. Our mobility equipment page covers the full range, and a consultation is free with no obligation.
Indoor turning, measured rather than guessed
Take a tape measure to the narrowest point of your hallway and the doorway into the bathroom. Then look at the turning radius in the specification.
Most three-wheel scooters need a good deal more room than an average hallway gives. Four-wheel scooters need more again. A mid-wheel-drive power chair turns close to its own length, which is why it is the indoor answer.
People discover this after delivery far too often.
Three wheels or four
On scooters, three wheels turn tighter and are less stable on a camber. Four wheels are steadier outdoors and need more room. If it will be used mostly on pavements and in shops, four is usually the safer choice.
Controls and who can use them
A scooter is steered with a tiller, which needs two hands and reasonable shoulder movement. A power chair is driven with a joystick, usually one hand, and can be fitted with alternative controls where a standard joystick will not work.
For somebody with arthritis in the shoulders, that difference alone decides it.
Complex rehab technology
Where the chair needs tilt, recline, powered legrests, alternative drive controls or a custom seating system, you are in complex rehab rather than retail. That work involves an evaluation, a clinical team and documentation, and it is not something to order from a website.
We hold ATP and CRTS credentials for exactly this. Our mobility equipment page explains where the line falls.
