I'm waiting to get the 70D on October, meanwhile, I'm planning to install the home charger or not, but my management only approve to install 13A slow charger. And the quotation is also considerable. So I hesitate to spend bulk money on slow charger. actually, I can charge at daytime at office (13A and supercharger available), and with proper planning, is it adequate to enjoy carefree model s without home charger? Anyone without home charger would share your experience? Thanks.
