What Will A 750 Watt Inverter Run ? [Top Reviews and Ratings for 2022]

A 750-watt inverter can run appliances, gadgets, and power tools like laptops, TVs, cameras, radios, and lights. This inverter offers 1500 surge watts, which can power a refrigerator, microwave, and power tools.

These kinds of inverters can power any combination of less-than-750-watt items. Newer inverters are 90-95% efficient. Therefore, available watts are 675-712 watts.

Some of the greatest 750-watt inverters you can trust:

Using this information and a wattage chart for each piece of equipment, you may determine which appliances can be used. Determine how much electricity you need. Appliance power consumption is measured in watts. However, amps can also be used and voltage affects amps-per-hour.

Calculating Watts: VA
Divide power by amps to get voltage.
A=P/V

750W inverter coupled to 320W load draws 2.6A at 120V AC.

320/120 = 2.6 amps

A 750-watt inverter with the same load using 24V batteries will need 13.3 amps.

320/24 = 13.3 amps

Multiply amps by volts for watts. The results are always rounded.

13.3 amps x 24V = 319.2
2.6 amps x 120V = 312

These are estimated. Let's consider inverter efficiency and runtime. 
A 90% efficiency inverter and 450-watt load produce the following:

450W/0.9=500W

This 450-watt load needs 500 watts. Inefficient devices use more power. That is why full-capacity inverters can be dangerous and may be weak.

750W inverters can power blenders, fans, microwaves, sump pumps, 1/2-inch drills, 1/4-horsepower motors, and garage door openers. Air conditioners and other appliances need more than 1500 watts and require a larger inverter.

How long will a 750-watt inverter maintain?

Batteries or 110/120V power an inverter. Inverters can run indefinitely on alternating current if there's enough power (AC). Battery charge determines runtime.

Make a list of everything you plan to power with the inverter to get an accurate estimation. Add watts to estimate battery life.
