You can, but you don't have any safety factor to speak of.
Look on the AC power adapter and read its rating in watts. You will need an inverter with at least that output capacity.
Yes, it is generally safe to start an AC motor with an inverter that has a higher power rating. The inverter's capacity should exceed the motor's power requirements to ensure sufficient starting torque. However, it is important to ensure that the inverter is correctly configured and that the motor is compatible with the inverter's voltage and frequency output.
Yes, provided the power inverter has a high enough power rating (wattage) for the CPAP device.
"Rotary Inverter: In a rotary inverter, DC electricity input powers a DC motor that turns an AC generator. Rotary inverters are reliable and produce a pure sine-wave output. These inverters have automatic load demand: they begin operation once a load is activated, and shut down when the load is removed. Disadvantages of a rotary inverter are lack of frequency control, low surge capability (50% above maximum rating) and lower efficiency (50% to 80%). Rotary inverters are not as common as electronic inverters."
Divide the output rating by the input rating
It depends on the 3 phase inverter. If it is a 3 phase input then you will first need to get a single phase to 3 phase converter to simulate a 3 phase supply, if that is what this particular inverter is intended for then you will have a label saying 230v primary with a L & N connection point, and the output will be labelled as secondary, giving you the inverted power rating. This is a very expensive way of running machinery as the inverted power is no different in conumption to the single phase.
Yes you will as CPU manufactures prefer if you use there CPU cooler as the cooler has been designed for the thermal rating of the CPU.
amps - how much electrical output
You put it togather. If the lighter outlet is rated at 120 watts [that's 10 amps at 12 volts] maximum, then that means that the receptacle, wiring to it, and the fuse cannot carry a 300 watt [25 amps at 12 volts] load, AND SIMPLY PLUGGING IT IN, as suggested in answer 1 should result in blowing the fuse for that circuit. Do NOT let anyone talk you into replacing the 10A fuse with a 25A fuse, as that is a guarantee for burning up your wiring, and possibly your car. However, you do not mention whether the 300 watt rating for the inverter is the OUTPUT or INPUT RATING. IF, and ONLY IF, when you check the INPUT wattage rating [should be on a label or stamped into the outer cover of the inverter], if it indicates an INPUT rating of 120 watts [10 amps at 12 volts] or less, then you can just "plug it in." If the inverter input current rating exceeds 10 amps at 12 volts, then it will not work. To provide adequate power for your inverter, it would be necessary to add-on a new circuit from the battery, or the main fuse panel, with properly sized wire[s] for the load, a proprly sized fuse to protect the wire[s], and a socket also properly rated for the electrical load.j3h.
The rating is about 1500W. This is for both the input and the output. Output voltage is usually 2,000 volts. Divide watts by input volts to get input current. And divide watts by output voltage to get output current. -Joe

It is a rating system to determine the power output of a vehicles engine.
