two considerations to think about:
Your commute length
Your needs to pre-condition the cabin
You may greatly benefit from a 220 charging unit! The 220 unit will Pre-heat the cabin in the winter or summer whilst plugged in without adversely affecting your EV driving range during the pre-heat. If you are on 110, then it will consume a bit of battery to warm cabin in the am. BUT, if you get a 220 charger it won't consume battery and you will have a smidge more range which could help you get to work on battery alone. Does that make sense? How long is your work commute? If it is under 20 miles than maybe don't worry about it.
