Casting Time: 1 standard action
Saving Throw: Fortitude negates (object)
Spell Resistance: yes (object)
You can transfer any number of charges from one battery to another battery or from one power cell to another power cell. You can only transfer charges using two objects of the exact same type (two batteries of the same size, two identical power cells, or the like); you transfer charges from the source object to the receiving object.
You must declare how many charges you are transferring before casting this spell. If you transfer more charges from the source than the receiving item can hold, the receiving item must succeed at a Fortitude saving throw or take 1d6 electricity damage. This spell provides no knowledge of how many charges a receiving item can safely hold, but you can choose to transfer fewer charges than the maximum allowed to reduce the risk.
