Electric Dab Rig (E-Rig) UK: How It Works & Buying Guide

By Mike Bologna · Updated June 8, 2026

An electric dab rig — also called an e-rig — is a battery-powered device that heats cannabis concentrate to its vaporisation point electrically, with no blowtorch. You load concentrate onto a heated element or into a chamber, the device reaches temperature on its own, and you inhale vapour, usually through water. It replaces the traditional torch-and-nail dab setup with a button and a battery.

How an electric dab rig works

  1. Charge and set the temperature. Most e-rigs offer preset heat levels.
  2. Load the concentrate into the heated chamber or onto the element when it reaches temperature.
  3. Inhale — the concentrate vaporises and the vapour draws through the mouthpiece, often via a water chamber for cooling.
  4. Recharge over USB — no torch, no butane.

The big advantages over a torch rig are consistency and safety: a precise, repeatable temperature instead of guessing with an open flame, and no need to wield a blowtorch.

Important: an e-rig vaporises — it doesn't combust

This is where we're careful with language. An electric dab rig vaporises concentrate; it does not combust dry herb. That makes it different from an electronic bong (eBong), which combusts dry flower to make real smoke. We describe each device honestly: the eBong is true combustion, the e-rig is concentrate vaporisation. If you want the full distinction, see vaping vs combustion. Calling an e-rig "combustion" would be wrong, and we don't do it.

Electric dab rig FAQ

Is an electric dab rig the same as an electronic bong?

No. An e-rig vaporises concentrate; an electronic bong combusts dry herb to make smoke. Different material, different process.

Do you still need a torch?

No — that's the point. An electric dab rig heats electrically, so there's no blowtorch and no butane.
