It's good that they're open to a discount Rick. People fall into two camps regarding powering electrical things off and on don't they

For many years now I've been in the 'leave it on' camp as long as only tiny amounts of power are consumed. This goes back to the early days of remote controls and 'standby' for hifi components and endless discussions in magazines about the pros and cons. Then the same discussions at work about computer and networking components. So I've always left my charger and EVSE plugged in and powered. I'm not sure there is any definitive research either way!
