Recharging costs are negligible which is why I never mentioned them. As I pointed out above, running a 200 watt charger for 45 minutes only costs 1.8 cents. But... Even if you do use a vehicle to charge the batteries, then the cost per charge should also include the 1.8 cents plus the cost of the inverter divided by the expected lifespan, in hours, of the inverter.
Bear in mind that even though the power for the inverter is coming from the vehicle, that power still must be created by the vehicle and therefore, has a cost.
