For example, if your DVD player consumes 100 watts and your laptop consumes another 100 watts, an inverter of at least 300 watts is recommended. Volts (120) x amps = watts.
It is your lasting effect. Even a refrigerator engine needs about three times the mileage to start, but this increase is required in just a fraction of a second. To make this refrigerator work, you need an inverter that can handle 600 watts over a long period of time and a wave of 1800 watts in a split second.
If you max out the 2000 watt inverter, you are using 2000 watts / 12 volts = 166.6 DC amps per hour. If using a 12 volt, 200 A battery, divide the battery by 200 A / 166.6 A = 1.2 hours of driving.

The deciding factor is the actual power, not the inverter power or (the size of the inverter). So a 1500 watt converter with a 500 watt load would be 50 (25) amps, not 150 (75) amps.
To get 3000 watts of 120-volt AC power from an inverter, you need to replace the 100-amp generator with an expensive 250-amp generator and install PI high-capacity batteries. In addition, an additional 50 amps are required to operate vehicle accessories, lights, turn signals, etc.
The 150W power converters can power phones, tablets and laptops. With 150W, you can also use small LED TVs, lamps and more.
Output current: 3.2 - 3.6 A (at 400 watts load) Interchangeable fuse: 40 A. Input high voltage shutdown:> 15 volts DC. Low input voltage alarm: <11.5 volts DC.
The number of batteries depends on the DC input requirements of the inverter. Typically, a 5 kW inverter has an input requirement of 24 VDC. So you need two 12V batteries. Some models use 48V DC, in which case you will need four 12V batteries.
So I replied: In my experience, your 12 V car battery with an inverter will last 1017 hours. Sure, there is a specific formula you can follow, but it will depend on the number of watts being charged and the number of amp hours on the battery.
If you don’t need a pure sine wave inverter
Square wave inverters are very difficult for electric motors. Typically, it takes about 12 A DC to operate 1 A AC, considering the voltage and efficiency factors. So if you have a 10 amp compressor, you should expect at least 120 amps from the battery or 1440 watts (120 A x 12 VDC).
The converters convert the 12 V DC voltage from batteries to 110 V AC for the operation of electrical devices.
