Use Car Battery To Power Appliances

A car battery rated at 80 amp hrs will theoretically give you 12 volts nominal at 80 amps for one hour or 8 amps for 10 hours.

Use car battery to power appliances.

Car batteries operate on direct current flowing at 12 volts. Use is measured in available amp hours. Most household plug in appliances on the other hand operate with 110 120 volts and the current is alternating meaning that there are two pulses of electricity passing through the wires flowing in alternating phases. Car chargers for your phone and possibly laptop many usb powered devices they re 5v but car chargers are common and most importantly a surprising number of appliances designed to run off of.

In tests researchers used a battery pack from an electric vehicle to provide 8 kilowatts kw of power enough to power the kind of appliances found in an average household.

How to use a car battery for powering household appliances it would be nice to be able to power certain household appliances like the coffee maker for instance from your car battery.
