just got mine on fenrir this morning, Wiki has some BS posted by some nutter that says you lose bonus if you take it off, tried it and it still works, not rechargeable though, traded it to a couple different NPCs in the past and even tried one in the present and nothing
Edit: if you use it once today can get 3 more uses drop it and buy a new one before sandy loses throne room XD
Not quite solid info, but that's what I found.
