Inverters can be extremely handy items – especially when the power is out. Inverters can be hooked up to a 12V power source and used to run devices which normally would be plugged into household 110V outlet. Inverters can be used with a car battery – even through a cigarette lighter or power port. Connecting directly to one or more batteries(battery bank) is another method of powering the inverter.
Below is a chart that provides general guidelines as to how many watts are required by a variety of devices. Obtaining the correct inverter size for the job is important and have always “oversized” by 10-20% to make sure it is sized sufficiently enough.
