This is a 500 watt inverter circuit that may be very useful if Electricity is being extinguished, the circuit is able to turn on the fluorescent lights can even turn on the television. This series is not recommended to charge the phone battery or laptop battery charging feared would damage the cell phone and laptop batteries, because the resulting shock is not smooth. The series is devoted only to strum emergencies if electricity is off. For the same durability depends battery, if the battery ampere small lights then certainly will not take long and if the amperage of the battery eg 60 amps will certainly last a long time. Be careful not to hold the transformer primary by shock due to a very strong power.
