Your grandfather has ALS? A power chair is a type of wheelchair that has batteries and is rechargeable. It can be operated with a control so it doesn’t have to pushed or propelled. One for a PALS will have a headrest, supports and things like a recline and tilt function and some other things. His clinic should order one specific to his needs You can buy used but insurance generally pays for one mobility device every five years. Use that for a power chair for him. If he just needs a transport chair right now you can buy something used for the meantime but talk to his doctor about the powerchair. It takes time to get one ordered and delivered
