Self-serving shit (sss) but in the SG Aux HQ/Outpost there is a charger animatron who will charge your weapon for a fee. The duration for this service could really use a boost, however, because the effect fades very quickly.
The spell level is atrociously low! Unless the Auxiliary base is flooded and attacked by trailblazing sahuagin, I fear that it will never be useful.
Perhaps you might consider replacing it with the weapon enhancer placeable?
Particularly in the case of outposts, it might act as a reward for ongoing donations.
