Microfusion cell

Microfusion cells, or simply fusion cells, are an ammunition item in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout 4, Fallout 76 and Fallout Tactics.

Background
Microfusion cells are small energy-production units roughly the size of the palm. Each cell is a self-contained fusion plant, complete with its own fusion reactor. They were invented in 2066 by U.S. scientists as a potential solution to the energy crisis amid the Resource Wars. As fusion often uses combustible hydrogen isotopes and requires an enclosed space with sufficient pressure and temperature, microfusion cells may explode if ignited. The No. 1040 MF model is able to provide 1040.8 DC volts and has both positive and negative terminals. 

Microfusion cell


The standard version of the microfusion cell.

Microfusion cell, bulk


The bulk version carries a smaller charge than the standard version, resulting in a reduction in damage and armor penetration, but less strain on the weapon.

Microfusion cell, max charge


The max charge version causes the maximum possible damage and armor penetration, but at the expense of increased weapon degradation.

Microfusion cell, over charge


The over charge version causes more damage and weapon degradation than the standard version but not as much as the max charge version.

Microfusion cell, optimized


Added in the Gun Runners' Arsenal add-on, the optimized version causes more damage than the standard version and over charge version and weighs less than the other versions, but with slightly increased weapon degradation.
