Abstract: A system and method for providing continuous AC/DC current for powering the appliances used by a truck driver in the cabin of transportation trucks in an economic and environment-friendly manner especially in countries that enforce non-idling laws on heavy trucks. The power generated in accordance with the presence invention relies only on the combustion engine of the reefer, independently of the main engine system of the truck. DC current is generated by an alternator, or a plurality thereof if needed, and then inverted into AC using an inverter. It is also possible to power the main engine and charge the batteries of the truck through the system when the truck is running using a switch that interrupts the main alternator of the main engine system of the truck reducing friction and power losses, which allows for more fuel savings and reduction in polluting gases emitted in the atmosphere.
