If you are almost out of amps at your panel, a relatively easy and inexpensive way to have plenty of charging smash for all but the most extreme cases (like returning home empty and needing to immediately press out on a 50+ mile drive) is:
Have an electrician wire a dedicated 6-20 (20 amp, 240VAC) outlet, which places only 5 more amps' draw than your standard 15 amp, 120VAC wall outlet, and get the 6-20 adapter for your Mobile Connector. Cost for a new breaker, the wire, the outlet, installation, and the adapter will probably be under $300.
That setup gives a TM3 15 MRPH, or 180 miles per 12-hour night. 20 amps at 240VAC is 2.67 times as much flow as 15 amps at 120VAC ((4800W v. 1800W), and your car, which uses some of that flow for vampire loads while you are charging, will use a greater proportion of the bigger flow for actual battery filling, hence the triple charging speed, relatively.
