## Abstract

A portable power source. The portable power source includes a housing, a first battery pack support configured to receive a first removable and rechargeable battery pack, a second battery pack support configured to receive a second removable and rechargeable battery pack, an inverter within the housing, and an alternating current power outlet. The inverter is configured to receive output power from the first removable and rechargeable battery pack and the second removable and rechargeable battery pack. The inverter is configured to produce an alternating current power output. The alternating current power outlet is configured to receive the alternating current power output from the inverter. The inverter is configured to be disabled when the first removable and rechargeable battery pack is received in the first battery pack support and the second removable and rechargeable battery pack is not received in the second battery pack support.
