Newer battery tech is helping improve the “compactness” of motorized chairs. We have a “fold and go” (https://www.foldandgowheelchairs.com/) which can fit in a car trunk (though still want a full size sedan or bigger if you plan on putting anything else in there) and at 60lbs is only about 50% heavier than some of the heavy “standard” chairs out there. Still not something you’re going to move well on your own without an able bodied assistant or some specialized equipment, but compared to older motorized chairs it’s a huge improvement
