RELX HERC 12000 vs Lost Mary BM6000: Compact Icons, Different Philosophies

By ONEWING GROUP LIMITED · Updated 2026 · Reading time: 8 min

The Lost Mary BM6000 is the refill-format category’s most decorated device: a 2ml pod automatically fed by a 10ml refill container, a rechargeable battery (650mAh in the original, upgraded toward 1000mAh in later runs), an OLED power display, a QUAQ mesh coil and a genuinely thoughtful touch — a detachable battery designed for recycling. It is, like the Elf Bar AF5000 we compared previously, a child of tank-capacity regulation; unlike the AF5000, it wears its engineering on a screen. The HERC 12000 remains the sealed-format flagship. Both are category icons; their philosophies barely overlap.

Same format family as the AF5000, better instrumented

Structurally, the BM6000 is the AF5000 formula with the dials turned up: 2ml pod plus 10ml container (12ml total), automatic refill feeding, USB-C recharging, and — the differentiator — an OLED display showing battery status alongside a visible e-liquid window. Where the AF5000 leaves status to a single LED, the BM6000 instruments its user the way the HERC does. For buyers comparing refill formats, this is the premium expression.

The HERC answers from the sealed-format side with its smart side display — battery and liquid indicators — so unusually for a cross-format comparison, both devices tell the user the two things that matter. Instrumentation is a tie; the formats beneath it are not.

The detachable battery: Lost Mary’s best argument

The BM6000’s release catch slides the battery out of the body for end-of-life recycling — and in the 2025 refresh, the battery capacity rose while the format gained replaceable prefilled pods. This is the most credible sustainability story in the category: a device whose power cell is not entombed with its spent liquid vessel. Our battery recycling guide scores this highly, and sealed disposables — the HERC included — honestly cannot match it.

The HERC’s counterpoint is lifespan amortisation: one 2600mAh cell delivering 18ml in a single life uses its battery exactly once, and an aluminium body that survives the device intact is more recoverable than polymer. But format-wise, the round belongs to Lost Mary, and we score it as such.

Capacity and ritual, revisited

Liquid: HERC 18ml sealed, BM6000 12ml across pod plus container — a 50% advantage to the HERC per purchase. Ritual: the BM6000 shares the refill format’s small obligations — insert container, invert, let the pod saturate before the first draw, repeat when the container empties — while the HERC asks nothing and delivers its extra 6ml with zero interventions. Battery: the BM6000 recharges via USB-C (its 12ml needs a handful of cycles); the HERC’s 2600mAh never asks for a cable.

The pattern from our AF5000 comparison repeats with sharper instrumentation on both sides: the refill format buys economy and separability at the price of ritual; the sealed format buys absolute convenience at the price of a shorter battery lineage.

Flavour breadth: a genuine Lost Mary strength

The BM6000 range spans three dozen-plus profiles built on Maryliq nic-salt formulations, and the brand’s flavour consistency across pods is widely praised — the QUAQ mesh earns its reputation. The HERC’s range is narrower and tuned for constant output across a single long life rather than pod-swapping variety. If your customers buy devices as flavour platforms, the BM6000’s breadth is a real advantage; if they buy them as appliances, breadth matters less than the HERC’s day-one-to-day-last consistency.

Verdict: the best of both formats, honestly scored

BM6000 wins: display parity with genuine OLED quality, end-of-life separability, battery economy across containers, and flavour breadth — four rounds, all earned. HERC wins: capacity per purchase (18ml vs 12ml), zero-cable architecture, zero-ritual operation, constant output and aluminium build — five rounds. As with the AF5000, the binding constraint is jurisdiction: where pharmacy-standard refill formats govern lawful supply, the BM6000 is the category’s premium answer. Where integrated capacity is lawful, the HERC is the more complete machine. Both verdicts are honest, and they are not in conflict.

Frequently Asked Questions

Which device has the better screen?

Both genuinely instrument the user: the BM6000 pairs an OLED battery display with a visible liquid window, and the HERC shows battery and e-liquid together on its side display. Presentation differs; capability is effectively a tie - and both beat the LED-only majority.

Is the detachable battery a big deal?

For end-of-life recycling, yes - it is the category’s most credible separability feature, and we score the round for Lost Mary without hesitation. The HERC’s counter is that its single 2600mAh cell is used exactly once per 18ml, with an aluminium body that recovers well - but the format advantage is real.

Which holds more e-liquid?

The HERC: 18ml sealed against the BM6000’s 12ml (2ml pod plus 10ml container). Note the BM6000’s battery persists across containers, so heavy users close some of that gap on a total-cost basis.

Can they be compared at all, given different formats?

Only honestly by scoring rounds and naming the deciding factor: jurisdiction. Refill formats align with pharmacy-standard product requirements; sealed high-capacity devices serve export and lawful trade channels.
