I've read that folks don't think it's good for the plug to keep plugging and unplugging. I'm guessing I'll just be too lazy. I'll obviously have it with me with all the adaptors for road trips.
Do I need it in the car for just daily driving with no range anxiety whatsoever? Are you doing this? Did you/Will you buy an extra UMC for this purpose?
If you have no range anxiety, like me, then why bother? I have a 46-mile round trip to work, so even with a bunch of side errands or going to the movies or shopping or whatever, I won't need to charge away from home. I never make unplanned road trips to other cities. ;-) You know what stuff you do around town, your commute, etc.--only you can judge what's best for you. But for my driving situation, I wouldn't unplug it just to have it with me.
Reading this thread makes me realize, though, since I have the bag o' adapters in the trunk (including the J1772 adapter), I can charge from a public charging station anyway. This wasn't exactly a conscious
plan, though. Whether or not this seems sufficient for you depends on your charging infrastructure and your driving situation.
I haven't looked closely, but I'm skeptical unplugging the adapter regularly is a big deal. But I only need to unplug if I go on a road trip, and theoretically my HPWC will arrive some day, and then I'll keep the UMC in the trunk with
all adapters since I won't need it at home any longer. But even without an HPWC I wouldn't buy an extra UMC (again,
my situation--no range anxiety, no need to charge, plus I have the J1772 in the trunk) since I don't believe that unplugging from the wall a few times a year is going to make the adapter fail. That's just silly IMHO; they can't be that fragile.
