Turn a Car Battery Into an Emergency Power Source For the Home

A 120 volt inverter will use roughly 10 times the amperage off the battery to power it''s load. Example…to power a 120v, 100 watt bulb pulls about .8 amps at 120v or 8 amps off the 12v battery. In theory, you could run the light for 10 hours before draining the battery to "dead" at about 11 volts.
