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

By Mike Bologna · Updated June 8, 2026

An electric dab rig — or "e-rig" — is a battery- or wall-powered device that heats cannabis concentrate to vapor with an electronic nail (atomizer) instead of a butane torch. You set a temperature, the element heats, you apply your wax or oil, and you inhale vapor. It does the same job as a traditional torch-and-glass rig, but with push-button temperature control and no open flame. Important to be clear up front: a dab rig vaporizes concentrate — it does not burn it. It is not "true combustion," and it is not the same as an electronic bong (eBong), which burns dry herb.

What is an electric dab rig?

A dab rig is the concentrate equivalent of a water pipe. Traditionally it's a glass piece with a "nail" or "banger" you heat with a butane torch until it's hot enough to flash-vaporize a small amount of concentrate (a "dab") on contact. An electric dab rig replaces the torch and the guesswork with electronics: an electric heating element brings the bowl to a target temperature, and many models let you dial that temperature in degrees. The vapor still draws through water or a small percolator on most units, so you keep the smooth, filtered pull of a glass rig while losing the torch.

You'll see e-rigs sold as countertop devices and as portable, rechargeable units. The common thread is the same: heat concentrate to vapor, electronically, with temperature control.

How an e-rig heats concentrate

Three parts do the work:

You wait for the device to reach temperature (seconds to a minute depending on the unit), apply concentrate to the heated atomizer with a dab tool, and draw. No torch, no waiting for a nail to cool, no butane.

Notice the last row: both a torch rig and an e-rig vaporize concentrate. Swapping the torch for an electric element changes the convenience and the consistency — not the underlying physics. You're heating wax or oil to vapor, not setting it on fire. That's the honest description, and it's why a dab rig sits on the vapor side of the vaping vs combustion line.

Where the line is: e-rig vs the eBong

This is the distinction worth getting right, because the words get blurred. A dab rig vaporizes concentrate. An electronic bong (eBong) combusts dry herb — it uses an electric heating element to actually burn flower with true combustion, producing real smoke, no flame. Same family of "electric, no torch" hardware; opposite mechanisms:

So if you're shopping for concentrate, an e-rig is your tool. If you want to burn flower without a lighter — the windproof, waterproof, flameless dry-herb experience — that's the eBong, built for dry herb instead. Don't expect one device to do both jobs well; they're built around different temperatures and chambers.

Who an electric dab rig is for

If you mostly want something pocketable, look at the electric dab pen. If you want the simplest possible "heat and sip" form factor, a dab straw or electric nectar collector may suit you better than a full rig. For the bird's-eye view of all of these, see electric dab (the category overview).

Buying guide: what to look for

The hub doesn't sell devices. For concentrate hardware we route to a concentrate specialist: see where to find an electric dab rig, dab straw or nectar collector (concentrate intent routes to Dip Devices). For dry-herb true combustion, that's a different brand list entirely.

Electric dab rig FAQ

Is an electric dab rig combustion or vaporization?

Vaporization. An e-rig heats concentrate to vapor below the burn point; it does not burn it. It is not "true combustion." That term applies to dry-herb devices like the eBong, not to dab rigs.

Is an e-rig the same as a dab pen?

They overlap. An electric dab pen is the small, portable end of the spectrum; a full e-rig usually has water filtration and a larger atomizer. Both vaporize concentrate electronically.

Do I still need a torch with an electric dab rig?

No. The electric atomizer replaces the butane torch entirely — that's the main reason people switch to an e-rig.

Can I use dry herb in an electric dab rig?

No. E-rigs are built for concentrate. To burn dry herb without a flame, you want an electronic bong (eBong) instead, which is designed for true combustion of flower.

What temperature should I dab at?

It's a preference. Lower temps (roughly 315–450 °F) favor flavor and terpenes; higher temps give bigger, hotter vapor. Start low and work up.
