MODULAR PORTABLE POWER STATION WITH BATTERY EXPANSION
A modular portable power station comprises a portable power charger that can be supplemented with battery expansion modules that can be mechanically and electrically connected, as needed, to increase power output and capacity. The power charger housing is adapted for mechanical connection to a battery expansion module. When the expansion module is mechanically connected to the charger housing, an internal battery of the expansion module is electrically connected to the internal battery of the power charger to provide a boost of additional power and capacity, which can be transferred to electronic devices in need of a charge. The expansion module includes connection means to complement the connection means on the portable power charger. Additionally, the expansion module may include further connection means, simulating the connection means of the portable power charger, so that multiple expansion modules can be connected to the portable charger, in series, at the same time.
1 . A modular portable power station comprising:
a portable power charger comprising:
a first housing including first connection means;
a first battery disposed within the first housing;
a plurality of ports disposed in the housing, said plurality of ports further a port for a jump start cable and at least one charging port; and
a controller for controlling the operation of the portable safety device; and
a battery expansion module comprising:
a second housing including second connection means adapted to complement and engage the first connection means to connect the battery expansion module to the portable power charger; and
a second battery disposed within the second housing;
wherein the first battery is in electrical communication with the second battery when the portable power charger is connected to the battery expansion module via engagement between the first connection means and the second connection means.
2 . The modular portable power station according to claim 1 , wherein the battery expansion module includes third connection means that match the first connection means of the portable power charger such that said third connection means complement and can engage second connection means on a second battery expansion module in order to connect two such battery expansion modules together.
