Got a heads up from my Motoring Adviser Gregg about the 110v charger that is very interesting.
As Copied:

Please remember it is very important to instruct MINI E customers that
not all 110v outlets are created equally. An outlet with sub-standard
grounding, or which is far from the electrical panel may not provide
"clean" power to the vehicle. Furthermore, plugging into a circuit which
is occupied by other appliances or consumers may negatively affect the
line voltage or capacity of the circuit and drop the available power to
below the minimum threshold to charge the car. A typical household
outlet should be rated at 15 Amps, the MINI E will draw 12A from an
outlet, so there is no room on the circuit to be shared with other
items. Situations such a s a brown or black out may also cause the
vehicle to stop charging, so please remind customers to check if the
vehicle is still charging after these occurrences. At times, if a
vehicle is connected to a building which experiences high electrical
consumption with many consumers operating simultaneously(pool pump, AC,
dryer, etc.), the voltage in the building may approach a situation close
enough to a brown out, and may interrupt vehicle charging. Lastly, no
extension cords are to be used to charge the vehicle.

Some common sense for those of us using 110v for now.
