The first step in choosing a power inverter is to determine the amount of power you require. If you are looking to purchase a power inverter you most likely have a very clear idea of what you are going to use it for. If you are not completely clear on what electronics you want to power with your power inverter then make gaining clarity your first step. When you know what electronics you want to power determine the amount of power necessary for them. The power requirement information is available on the back of most electronics and appliances.
Once you determine the power requirements of all the equipment you would like to power the second step is to determine what equipment will be running simultaneously. The more equipment you use simultaneously the more total power you need available at any given moment.
Third, add up the amps and/or watts. To calculate watts you multiply amps by 120. To get amps you divide watts by 120. Example:Let’s say you want to run a microwave and a coffee pot. The microwave is 8 amps and the coffee pot is 5 amps . You add the total amps which is 13 and multiply by 120. . You get 1560 watts. Because microwaves and coffee pots have a start up, we recommend you allow double your wattage which is 1560 * 2. You will need at least a 3120 watt inverter. Since inverters are usually sold as 2500, 3500 or 5000 watts, you will have to decide what is the best investment for you.
