Assuming energy weapons ala D20 modern exist in a campaign, does this power seem OP?
Energize Weapon
Level: Psychic Warrior 2
Manifesting Time: Attack action
Range: Touch
Duration: Until discharged; up to 24 hours
Effect: Adds 4 charges to an extant energy weapon such as a plasma pistol or laser rifle.
Saving Throw: None; Power Resistance: No
Power Points: 3
This power provides charges to an energy weapon that does not have a power source or is drained of charges, but is otherwise functional. The device functions exactly as it normally would if it had conventional power.
