Abstract: In situations where services or operations are being conducted in the field away from infrastructure, it may be useful to have a portable power system to power drones that require battery packs and have relatively short life times. A portable power system, such as a portable drone power station, may be uniquely qualified to provide affordable remote backup power. A portable drone power station may comprise a case with at least one handle. Inside of the case there may be a plurality of lead acid batteries connected to a power inverter connected to a power supply to charge one or more drone batteries. The lead acid batteries may be monitored by a battery level indicator.
