1. Check the power rating of the space heater in watts. This information can usually be found on the heater's specification label or in the user manual.
2. Multiply the power rating by 1.2 to account for the startup surge current of the heater. This will give you the approximate continuous power draw of the heater.
3. Select a car power inverter that has a continuous power output rating at least equal to the continuous power draw of the space heater. It's recommended to choose an inverter with a slightly higher power rating to provide some headroom.
4. Make sure the car power inverter has the appropriate output voltage and outlet type to match the space heater. Most space heaters require a standard AC outlet with a voltage of 120 volts (in North America) or 230 volts (in Europe).
For example, let's say you have a small space heater with a power rating of 1000 watts:
1. Multiply the power rating by 1.2: 1000 watts x 1.2 = 1200 watts
2. Select a car power inverter with a continuous power output rating of at least 1200 watts.
3. Check that the inverter has a standard AC outlet and the appropriate voltage (120V or 230V) to match the space heater.
In this example, you would need a car power inverter with a continuous power output rating of at least 1200 watts and a standard AC outlet with a voltage of 120V (assuming you're using it in North America).
It's important to note that the size of the inverter you need may vary depending on the specific space heater you have and the conditions under which you're using it. For safety reasons, it's always a good idea to choose a slightly higher power inverter than the heater's power rating.
