I have an 85D on order and since I have plenty of time to wait, I thought I'd see if my current thinking is correct with regards to my planned charging arrangements. I ordered the single charger because of a few reasons: No longer offered as a production item obviously, retrofit only I don't forsee needing rapid charging at home and don't intend on taking this on long road trips The road trips I do intend on taking have SC on route The HPWCs I see available in the DFW area (public), the majority of them are 40A or lower, so no added benefit On the wait list for a CHAdemO adapter as there are a few in Dallas, so no dual chargers needed However, I may later on decide to add the dual chargers if I see the need arises. I have a 70 mile round trip daily commute to two different offices of mine. Because of the reasons above and going with a single charger, my original plan was to install a 14-50 at home and at both offices. The majority of the time I wouldn't need a charge at the office, but I liked the idea of having it as a safety net in case I needed to make a spontaneous drive during the day to a customer's house/business. And to avoid having to unplug and bag my UMC each morning, I was going to buy a spare UMC to keep in the car at all times. Now, I'm thinking, if the HPWC is $750 and an additional UMC is $650...why not go ahead and get the HPWC (and have the wiring run for 100A if possible) and just keep the UMC that comes with the car in the car for charges at the office. The actual cost is only $100 more and I'm somewhat future proofing my home-charging arrangement should I decide to upgrade to dual chargers. I'll continue to install the 14-50 at my offices because I don't foresee needing that fast of a charge at my office, plus the expense aspect. Am I correct in my thinking or am I overlooking something? Thanks all for the help of this great forum!
