Re: How much power in watts dose the average home computer use?

A typical 14 inch monitor would consume about 80 watts.
And a typical computer's power supply is built to handle 
around 200 watts. 
To be on the safe side it is better if u use an inverter
with a power rating of at least 300 watts.
My advice would be to go for a 500 watt inverter or higher. 
Using a higher wattage inverter than what is required 
will not harm your truck.
Contact your Truck's dealer/manufacturer and verify 
whether your truck's electical system can handle the extra 
load of 300 watts.
Be careful in how u wire the inverter to your truck's
electrical system. Its better if a service person from 
the store where u buy the inverter can can do it for u.
