As a rule of thumb, a 12VDC appliance is going to require roughly 10X the current of a 120VAC appliance to perform the same function.
* - This is not wholly accurate due to the nuances of AC vs. DC and resistive vs. inductive loads, but it is a good RULE OF THUMB that people without 4 years of physics and/or an electrical engineering degree can work with.
Something that takes 7 Amps like a coffee maker will take around 70 Amps to perform the same function in the same amount of time.
As a tradeoff to not having to direct-wire the coffee maker straight to your battery bank using automotive jumper cables, and not having a coffee maker the size of a microwave oven, the heating element is designed to draw less power. That's why it takes longer.
