Ion double blaster
From Wookieepedia, the Star Wars wiki.
The ion double blaster was a form of ion weapon used by the B1 battle droid owned by Wittin during Jabba the Hutt's demolition contest. When charged up, it had the capacity to disable anything from a Rancor to a T-47 snowspeeder in a single shot, but would have to be charged up again after every shot.
