Our new Mercedes GLC 350e can easily go 25 miles on a charge but, at 110v, it takes about 12 hours to recharge the batteries. With this contraction, it charges in under 2 hours. So, if we decided to go out for dinner - we can drive back to town with a full charge. It was easy to install once my electrician gave us 250v to plug into. A nice feature is to see at a glance the charging status without having to walk over to the wall.
