Battery Dildo

A power adapter which, instead of a standard power jack, uses a plastic shell in the shape of a battery, but with leads extending to an AC adapter to provide power to a device.

The term was popularized by Cathode Ray Dude on YouTube in 2021, although it may have been in use prior to this.

In lieu of powering his camera with a battery, Gavin chose to use a battery dildo with a wall wart.
