The 10:1 relationship really bites us when using inverters to power high power devices like coffee makers, heaters, and AC because the current on the 12V side gets very high requiring short fat wiring (I.e., large gauge). For example, a 1.2kW heater will draw 1,200W/12V=100A which is a lot of current!
So true. And this is also why you want to mount the inverter as close as possible to the battery. 12-volt conductors needs to have 10 times the cross sectional area to carry the same wattage as 120-volt conductors.
