NOTE: Do not use this type of Generator with sensitive equipment (Computers, LCD TV, Caravan Charging systems and anything with a computer chip) unless you have an in-line "Surge Protector." These generators are designed to run power tools and the electricity output is not controlled. This can result in damaging your equipment.
