RELX HERC 12000 vs Gunnpod EVO 15000: The Charge-Free Showdown

By ONEWING GROUP LIMITED · Updated 2026 · Reading time: 7 min

Almost every high-capacity disposable on the Australian market asks you to recharge it two to six times before the e-liquid runs out. Only a handful of designs made the opposite bet: size the battery so the device dies exactly once, with the reservoir empty. The Gunnpod EVO and the RELX HERC 12000 are two of them, and they arrive at that shared philosophy by very different routes. Here is how the two charge-free designs compare on verified specifications — written for trade buyers, not consumers.

The shared philosophy: one life, one battery

The Gunnpod EVO pairs a 16ml reservoir with a 2500mAh cell; the HERC pairs 18ml with 2600mAh. Both are engineered so the battery delivers the full rated liquid without a charging cable. That single decision eliminates the most common failure mode of the category — the dead battery with e-liquid still inside — and with it, a whole class of counter complaints. For a retailer, a device that cannot be “not charged enough” is a device that cannot be returned for the wrong reason.

Everything else about these two devices flows from that choice. Batteries this large demand disciplined power management, honest capacity maths and — on the HERC — indicators, because the user can no longer use “is it charging” as a proxy for “is it working”.

Capacity and modes: 15000 vs 12000 is not the whole story

The EVO advertises two ratings: up to 15,000 puffs in Regular mode and 12,000 in Pulse mode, where the output profile intensifies. Credit where due — publishing both numbers is more honest than the industry norm of quoting only the gentlest setting. The HERC rates 12,000 puffs from 18ml at constant output: no modes, no switching, no user-configurable way to consume liquid faster than the label implies.

For trade buyers the question is which behaviour you want at the shelf. Mode-switching devices sell an extra feature but also sell variance: two customers buying the same SKU can burn through it at different rates and blame the device. A single-profile device trades that flexibility for predictability — the same reason fleet buyers prefer one engine tune.

The display question: information versus silence

The HERC carries a smart side display with separate battery and e-liquid indicators; the EVO has no screen. On a rechargeable device, a screen is a convenience. On a charge-free device it is the only instrument the user has: without it, the answer to “how much is left?” is weight, guesswork and dry pulls. The EVO’s silence is coherent — Gunnpod keeps the device simple and the price sharp — but it leaves the single most useful piece of information (remaining liquid) unstated until flavour starts to thin.

Our field guide to smart displays covers why dual indicators — power and liquid separately — outperform single lights in reducing “it stopped early” confusion. On a sealed 18ml reservoir, that is not a luxury feature; it is the fuel gauge.

Build and materials: where the price difference lives

The HERC’s aluminium body costs more to make than the EVO’s polymer shell and behaves differently in the hand and on the shelf: it dissipates coil heat better, survives pocket life without scuffing into “used” appearance, and reads as a premium object at the counter. The EVO’s lighter build keeps its street price down, which in price-led channels is its own argument.

Neither approach is wrong; they price differently. But if your customers handle the device before buying — and in the channels that still move these products, they do — material feel moves units in a way spec sheets do not.

Verdict: same bet, different execution

The EVO is the value expression of charge-free design: 16ml, honest dual-mode ratings, no screen, sharp price. It wins on simplicity of bill of materials and, usually, on sticker price. The HERC 12000 is the full expression: 18ml (2ml more juice), a larger 2600mAh cell, dual indicators on a smart display, aluminium construction and constant-power output. It wins on information, materials and capacity.

Score it honestly and the HERC takes capacity, display, build and consistency; the EVO takes price and mode flexibility. If your channel competes on price alone, the EVO is a rational pick. If your channel competes on experience and repeat custom, the HERC’s extras are exactly the differences repeat customers notice.

Charge-Free Head to Head

Frequently Asked Questions

Which lasts longer, HERC 12000 or Gunnpod EVO 15000?

On liquid, the HERC carries 18ml against the EVO’s 16ml. On rated puffs, the EVO’s 15,000 figure applies to its gentler Regular mode; in Pulse mode it rates 12,000. Real-world longevity depends far more on draw length than on either rating - our honest maths guide shows why.

Do either of these need charging?

No. Both are engineered so the internal battery delivers the full reservoir without a cable - the defining feature both devices share, and the source of their reliability advantage over 650-850mAh rechargeable rivals.

Why does the HERC have a screen if it never needs charging?

Because the screen is not about charging - it is about remaining e-liquid. On a sealed 18ml reservoir, the liquid indicator is the fuel gauge; the battery indicator confirms the cell is keeping pace. Both together end the guesswork that generates premature-death complaints.

Which is better for wholesale?

Price-led channels favour the EVO; experience-led channels and repeat-custom businesses favour the HERC’s capacity, display and aluminium build. Both avoid the recharge-cycle failure class entirely, which is why they lead this comparison tier.
