Energizer

Energizers were starship components necessary for the recharging systems of P-s4 twin ion engines present in spacecraft like the TIE/LN starfighter, in use by the Galactic Empire. Energizers were sensitive devices that needed to be properly aligned to work as intended. Misalignment of energizers in ion engines was dangerous, as they could explode like a time bomb.

Around 0 ABY, Rebel Alliance intelligence operative Anduvil destroyed the Imperial garrison base on the Outer Rim planet Tatooine, by infiltrating the hangar bay and misaligning the energizer of a TIE fighter's ion engine, causing an enormous blast that engulfed the military installation.
