A dab rig that is electronic.Instead of relying on a torch, e-rigs heat a nail electronically and have internal temperature controls. E-rigs can be a standalone device or an attachment for a separate dab rig.

Instead of using a torch like traditional dabbing, e-rigs heat a nail with a battery or plug into a wall. A water chamber, which is essentially a small bong that sits on top of the electronics, is present in standalone units. Concentrates are infused directly into some e-rigs by attaching it to the nail or downstem.
Each brand has its own distinctive features, fittings, and glass pieces because e-rigs typically use proprietary technology.
