Question: My friend admires my Jazzy electric wheelchair, but he lives in a house built years ago before they wired them with the third wire ground in the electrical wall sockets. He has noticed that the charging wire on my Jazzy has a three-pronged plug for the new style electrical socket. If he buys a Jazzy like mine with a three-pronged charging wire, can he use an adapter with three female holes for his charging plug but with the two male prongs to fit his old-style electrical wall outlets? What effect would that have on his Jazzy? ~Wallace

Answer: Probably, although without the ground his wheelchair won't be protected against short circuits or surges. If it's a new chair, this could nullify your warranty. It is best to check with American Mobility, the company that manufacturers the Jazzy line, to see what they advise you to do.
