The old charger you could hear while it is charging; this one is quiet. That is good and not. It is nice that it's quiet, but the other one you know it's charged when it shuts off. This one just has red/green light. My husband likes it is a bit smaller, enough that he can carry it in the seat pocket. He can recharge it when he is away from home.
My husband is in his hoveround most of the day. He is able to stand up and walk, but his doctor doesn't want him on his feet because he is trying to heal blisters. It's hard to keep it charged when he is on it so much, and he questions if it's getting a full charge when it runs down. But a charge lasts about 2-3 constant use hours, so I don't know how long it should last. But he goes to his regular wheelchair while it charges and he keeps going!
