Abstract: A mobile AC power system wherein the DC current of battery is converted by a power inverter electrically coupled to the battery terminals and the inverter is also mechanically coupled the battery. An AC outlet is positioned to provide a source of power and the unit has a power input being configured to receive a charging current for the battery. The AC outlet is disabled when the power input is receiving a charge.

Abstract: The present invention provides an external battery package unit (10) which houses mechanical and electrical components (32, 34) intended to be electrically connected to a battery (20) and be conveniently mounted to a top surface (22) of the battery (20). The battery unit (10) is made to fit within existing battery size constraints. In an exemplary embodiment, the external battery package unit (10) comprises a first housing (32) which acts as a mechanical compartment and a second housing (34) which acts as an electronics compartment. The first and second housings (32, 34) are secured to one another by a mounting member (30) which adjustably receives a portion of the first and second housings (32, 34) so that a distance between ends of the first and second housings (32, 34) is variable and the relationship between the first and second housings (32, 34) may be adjusted according to external parameters, such as the size of the battery (20) and different tolerances between battery post terminals.
