Hypercapacitors

Hypercapacitors are electrical storage devices with enormously high capacity by modern standards. Hypercapacitors were invented late in Era-0 on Earth.

Hypercapacitors are typically made from graphene, and other, similar materials, using nano-construction techniques.

Hypercapacitors power most of the day-to-day applications of technology in the galaxy. Jetpacks, hovercars, robots, and rayguns all use hypercapacitors as their main power sources.
