Need some clarification on an item

[Techwright]

I can't seem to find any info on this.  I know it gives a rested bonus up to 5 times per character before removal.  But it only appeared in the trays of some of my characters, and not all of them.  Was it something I was rewarded by a mission, or something assigned by the game, and if so why only a few of my characters?  If possible, I'd like to get one for each character.

The Experienced temporary power is what you're thinking of, I think? Characters that were created during the anniversary window last April/May timeframe got 5 charges, wouldn't be surprised if they're doing the same thing for the 16th anniversary next month. Other than that you can get them as character items in super packs.
