Extra power source

Upgrades (Universal Upgrades)

Any equipment that runs on energy cells or power packs can be modified to have two such power sources, doubling the duration the device will function (or the number of shots a weapon can make before being recharged). It's possible to make this modification more than once, adding an additional energy cell or power pack each time. The energy cells or power packs are typical for the device upgraded, and each is replaced at the normal cost.
