Capacitors to store DC voltage, transistors to switch power to the AC load, plus control circuitry to time the switching to match the (assumed) 60Hz AC frequency.
A 1,000 watt inverter giving 110 volts is rated at 9 amps.
Of course it is possible to make an inverter with a p-MOSFET!

No. The 12volts will not make a difference. The inverter converts the 12volts to 110/115volts. A 400watt inverter is not sufficient to run a power saw or any heavy power equipment like that. Laptops consume 20-50watts, while a coffee pot would consume more like 200-400watts. Your power equipment is a much heavier load, between 1000-4000watts depending on if it is a power saw or something larger. A basic 7 1/4 circular saw will use anywhere from 1000-2500 watts on starting and will draw a constant 800-1500 watts. Keep in mind it will draw more as you put it under load of cutting something, this will not run on a 400 watt inverter, let alone an 800 or 1000watt. You could however possibly run a power drill on that inverter, but otherwise no luck.
Since the charge is for "watt-hours", if everything is being run per specifications, then the price is the same.
Until you switch off!
Yes, you can use an inverter to power a 12V winch, but keep in mind that the inverter's voltage output should match the winch's voltage requirement. Additionally, make sure the inverter's wattage capacity can handle the power draw of the winch to prevent overheating or malfunction.
You can use a frequency converter to change the output frequency of the inverter from 60Hz to 50Hz. This will allow you to use devices that are rated for 50Hz frequency with your 110V 60Hz inverter. Just make sure to select a frequency converter that is compatible with the power output of your inverter.

An inverter does not store energy.
