RELX HERC 12000 vs WAKA soPro PA10000: Boost Mode Meets Steady Power

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

Here is a comparison you do not see often: two devices carrying the exact same amount of e-liquid — 18 millilitres — that could not be more different in how they deliver it. The WAKA soPro PA10000 spends its liquid through a 0.6Ω dual mesh coil with a Boost mode that fires both coils at once, powered by an 850mAh battery you recharge every few hundred puffs. The RELX HERC 12000 spends the same 18ml through constant output from a 2600mAh cell that never needs a cable. Same fuel; two completely different machines.

The battery maths that decides this comparison

The soPro’s 850mAh cell is honest about its limits once you run the numbers: independent testing puts standard-mode endurance at roughly 450-500 puffs per charge, which means an 18ml reservoir demands somewhere around twenty recharge cycles before the last drop is vapour. Each cycle is fast (USB-C, under an hour) but each one is also an interruption, a cable, and a period where the device is unusable.

The HERC’s 2600mAh cell holds roughly three times the energy and is matched to the reservoir so it delivers all 18ml in one continuous life. In our charge-free design explainer we call this the single-death requirement: the device should end once, empty, with no stranded liquid and no stranded charge. The soPro cannot meet it by architecture; the HERC meets it by design.

Boost mode: the feature the HERC refuses to have

WAKA’s DUALBoost system is genuinely clever engineering: a base toggle switches between a single 10.8W coil and both coils firing simultaneously. Boost delivers noticeably denser vapour — and consumes liquid and battery measurably faster. The HERC offers no modes at all: one calibrated output, constant across the whole device life, the same draw at puff 1 and puff 11,900.

Trade buyers should read Boost mode as a liquid-accelerator with a fun label. Customers who live in Boost will empty 18ml well before any 10,000-puff arithmetic says they should, and the variance lands on the retailer as “it didn’t last”. Constant output removes the knob entirely — less theatre, fewer arguments.

Coil and flavour: WAKA’s real strength

Give the soPro its due: the 0.6Ω dual mesh configuration is a flavour-first design, and reviewers consistently rate WAKA’s flavour delivery among the best in the category. Sub-ohm mesh in a disposable is expensive to do well, and WAKA did it well. The HERC’s mesh is tuned for consistency rather than intensity — the goal is that the flavour you taste on day one is the flavour on the last day, rather than a peak that fades as the cell sags.

If your customers prioritise maximum vapour density over everything else, the soPro’s Boost button earns its place. If they prioritise a device that behaves the same every day, constant power is the quieter, better answer.

Indicators and build

The soPro carries clear battery and e-liquid indicators — to WAKA’s credit, on a device this price that is not universal. The HERC’s smart side display provides the same two readings in a larger, glanceable format, which matters more than it sounds: a reading you can see across a room is a reading you actually use. On build, the HERC’s aluminium chassis again outclasses the category-standard polymer, though WAKA’s high-impact shell is better than most.

Verdict: intensity versus integrity

The soPro PA10000 is the enthusiast’s choice: best-in-class coil, Boost theatre, honest indicators, and the inconvenience of a device that lives on a cable. The HERC 12000 is the operator’s choice: same liquid, three times the battery, zero cables, constant output, aluminium build. WAKA wins the flavour-intensity round and the enthusiasm argument; the HERC wins battery architecture, consistency, materials and total cost of ownership.

For a shelf, this is not close: the HERC’s charge-free delivery of the same 18ml is the difference between a device that finishes and a device that waits for a charger that nobody in this category ever seems to have.

Same Millilitres, Different Machines

Frequently Asked Questions

Both hold 18ml - why does one need charging?

Battery capacity. The soPro’s 850mAh cell holds about a third of the HERC’s 2600mAh, so it must be recharged roughly twenty times to vapourise the same 18ml. The HERC sizes the cell to the reservoir so the whole device runs on one charge, ever.

Is Boost mode worth the faster liquid use?

It is a legitimate feature for vapour-density enthusiasts, but it is honest to describe it as spending liquid faster for intensity. Customers who mainly use Boost will find the device empties well before rated arithmetic suggests.

Which has better flavour?

The soPro’s sub-ohm dual mesh is tuned for maximum flavour intensity and is excellent at it. The HERC tunes for consistency - the same flavour from first puff to last. Intensity versus integrity is a genuine preference question; neither answer is wrong.

Which should a retailer stock?

Channels serving enthusiasts may do well with the soPro. Channels serving mainstream repeat customers see fewer complaints and fewer returns with charge-free constant-output designs like the HERC - the failure modes it eliminates are the two most common in the category.
