What can a 500 watt inverter run?

A 500 watts inverter has enough power to run a small refrigerator, laptops, tablets, cellphones, digital cameras, power tools, game consoles, TVs, DVD players, and other low-powered devices.

Will a 500 watt inverter run a refrigerator

Although a 500 watt power inverter might be enough to run some smaller fridges, we would recommend buying a power inverter with a higher power rating, and a higher surge peak rating.

To find out the exact size inverter you would need to run your fridge use the calculation below.

How Much DC Amps Does a 500 Watt Inverter Draw?

The formula for calculating how much DC amps an 500 watts inverter will draw is as follows: 

 Watt (Power) = Volts (Voltage) X Amperes (Current) 

Current drawn by a 500w inverter (500/110) A = 4.55 amps
