-I have next to no clue what I am talking about- Wouldn't a "wheelchair as powerbank" be the best solution to get people as mobile as possible?

It's not bad. Then you just have the issue of the cost of the batteries.

It's possible to have the device be corded and stay within a room or set of rooms.

I meant more like wheel(?) shop to shop, do the shopping on foot so it charges while wheeling.

Is wheeling the verb for it anyway?
