Well we know that a 1400 W charging rate (factory EVSE) is less efficient than a 3300 W charging rate. (Level 2 EVSE) In other words, you will use more kWh to fill up the battery.
What would the efficiency be for a 700 watt charge? Well, assuming a 10.8 kWh charge at 720 W you're looking at 15 hours minimum. I'd guess closer to 18 hours factoring in charging losses.

21,000 mi total / 10,300 mi electric / 10,700 mi gas / 62 mpg
Estimated fuel savings vs. my truck: $7500
