What’s the Difference Between BM600 & BM6000 Lost Mary Vapes?

Ready to buy? Get the Lost Mary BM6000 or the Lost Mary BM600.
The Lost Mary Lost Mary BM600 vape kit and BM6000 pod kit are both prefilled pod kits from the Lost Mary collection, but they're built for different vapers. One's a compact 600 puff kit that fits in any pocket. The other uses a reserve container to stretch a single refill pack to approximately 6,000 puffs - hence the name 'BM6000'.
Both replaced Lost Mary's old disposable vapes after the UK ban in June 2025. They share the same flavour range, the same 20mg nic salt e-liquid, and the same draw activated setup with no buttons or settings. The differences simply come down to size, battery, puff count, and how the pods work.
This guide breaks down exactly how the two compare so you can work out which one fits the way you vape best.
The short verdict
For most vapers, the BM6000 is the better buy. On the printed puff counts it works out around three times cheaper per puff. It goes far longer between pod changes, has the bigger battery and a proper percentage charged display screen.
The BM600 wins on two things only, and they matter to the right person: it is the smallest, lightest option, and at £4.99 it is the cheapest way into a Lost Mary kit. If you vape lightly and loved the size of the old 600 puff disposables, get the BM600. Everyone else is better served by the BM6000.

What Does BM6000 Mean?
People ask what the BM stands for on a Lost Mary, and the honest answer is that Lost Mary has never officially said. In practice the letters are simply the prefix for this model line, and the number that follows is the rated puff count: a BM600 is rated at around 600 puffs per pod, and a BM6000 at around 6,000 puffs per refill pack. Treat both numbers as manufacturer ratings rather than promises, because how you draw changes what you actually get.
The original BM600 and BM6000 were single use disposable vapes. After the UK disposable ban in June 2025, Lost Mary kept the same names but turned them into rechargeable prefilled pod kits. The names have carried over, but the products are completely different now.
You might also see references to the BM8000 and BM10000 Vision online. These are newer Lost Mary vapes with higher puff counts that follow the same naming pattern.
How Does the Lost Mary BM6000 Work?
The BM6000 uses a reserve container setup to get around the UK's 2ml TPD limit on pod capacity. Here's how it works:
The kit comes with a 2ml pod and a separate 10ml e-liquid container. The container connects to the pod and tops it up on its own as you vape. You don't need to fill anything yourself. The e-liquid moves from the container into the pod gradually, keeping the pod topped up until the container runs dry.
That's how you get approximately 6,000 puffs from a 2ml pod. The pod itself only holds 2ml at any one time, but the reserve container feeds it another 10ml over the life of the refill pack.

Setting up a new BM6000 refill pack:
- Take the silicone plug off the pod
- Slot the pod into the kit
- Push the e-liquid container in until it clicks
- Tip the device upside down for 5-10 seconds, or until the bubbles stop
- Wait 3 to 5 minutes for the pod to soak
- Start vaping
The kit is draw activated. No buttons, no power settings, no menus. You inhale and it fires on its own.
How Does the Lost Mary BM600 Work?
The BM600 is more straightforward. There's no reserve container. You get a single 2ml prefilled pod that slots into a rechargeable battery.
When the pod runs out after approximately 600 puffs, you pull it out and click in a fresh one. That's it.
Setup is the same idea as the BM6000 but without the container step. Remove the plug, slot the pod in, wait a few minutes, and you're vaping. Draw activated, no buttons, no settings.
The BM600 is closer to how a disposable vape worked. One pod, use it until it's empty, swap it for a new one. The only difference is you're keeping the battery and just changing the pod.
How Long Does the Lost Mary BM6000 Last?
The BM6000 refill pack gives you approximately 6,000 puffs. How long that lasts in days depends on how much you vape.
|
Vaping Frequency |
Approx Days Per Refill Pack |
|
Light (under 200 puffs a day) |
4+ weeks |
|
Moderate (200 to 400 puffs a day) |
2 to 4 weeks |
|
Heavy (400+ puffs a day) |
1 to 2 weeks |
Puff counts are always approximate and vary based on draw length and vaping style. Longer draws use more e-liquid per puff, so heavy vapers with long draws will get fewer total puffs.
The 1,000mAh battery lasts a full day for most vapers before it needs charging. It charges through USB-C and takes roughly an hour from flat to full.
How long does the BM600 last?
The BM600 lasts for approximately 600 puffs per pod. For most vapers that's one to three days depending on usage. The 750mAh battery is enough to get through a full pod before it needs a charge.
Which is better value: BM600 or BM6000?
On paper, the BM6000. Here is the maths from our own prices, and below it the honest caveat most guides leave out.

Now the caveat, because we will be straight about it where most guides will not: printed puff counts are approximate, not a guarantee. The two kits use different coils, fire differently, and how long you draw changes how much liquid every puff uses, so nobody gets the exact number on the box.
From what we see with our own customers, a moderate vaper gets through roughly six BM600 pods or a couple of BM6000 refill packs over a similar stretch, which puts the real weekly spend much closer together than the per-puff sums suggest. The BM6000 still edges it on value, but treat the table as a guide rather than a promise.
Why 600 puffs might make a comeback in October
There is a twist coming to this comparison, and it is worth knowing before you pick a side. When the Vaping Products Duty arrives on 1 October, it'll be charged on every millilitre of liquid. So the bigger the refill, the bigger the jump at the till. A BM6000 refill pack carries 12ml and climbs from £5.99 to over £9.
A BM600 twin pack carries 4ml and goes from £3.99 to around £5. The BM6000 keeps its value edge on paper, and that does not change. But the amount leaving your pocket each time you buy changes a lot, and we think that matters more than the spreadsheet says it should.
Vapers in the UK grew up on 600 puffs. It is the size everyone started on when disposables first arrived, and a fiver at the counter feels very different from a tenner, even when the tenner works out cheaper by the maths.
There is a second pull too: a 2ml pod is finished in a day or two, so you can change flavour as often as you like, while a 12ml refill commits you to one flavour for a week or more. Our honest bet is that the 600 puff format quietly wins back a share of vapers once the duty bites, for the same reason it won the first time. It is the easy, low-commitment way to vape. Our vape tax guide covers exactly what changes and when.
We have since put that call fully on the record: our 600 puff comeback prediction sets out the duty maths, the honest counter-argument and the three kits we back.
What Nicotine Strength Are Lost Mary BM6000 and BM600 Pods?
Both the BM6000 refill pods and BM600 refills use 20mg nicotine salt e-liquid. That's the only strength available across both ranges right now.
20mg nic salt gives a smooth throat hit without the harshness you sometimes get with freebase nicotine at the same strength. It's the same strength that was in the original Lost Mary disposables, so if you used those before the ban, the nicotine hit will feel the same.
There are no 10mg, 5mg, or 0mg options for either kit yet. If you want a lower nicotine strength, a refillable pod kit with nic salt e-liquid at 10mg or 0mg shortfill gives you that flexibility.
Lost Mary makes that route easy too. The Maryliq bottled range carries the same flavours in 5mg, 10mg and 20mg for refillable kits, and our Maryliq flavours guide ranks every bottle with honest tasting notes.
Which Lost Mary Kit Should You Get?
It depends on how you vape and what matters most to you. If the smaller device suits your style, you can buy the Lost Mary BM600 vape kit directly.
The BM600 suits you if:
- You're a lighter vaper who doesn't go through much e-liquid in a day
- You want the smallest, most pocket-friendly option
- You liked the size and shape of the old 600 puff disposables
- You don't mind swapping pods more often
The BM6000 suits you if:
- You vape regularly throughout the day and want fewer pod changes
- You'd rather carry one refill pack that lasts a week or more
- You want a battery percentage screen so you know exactly when to charge
- You prefer the longer lasting setup even if it's slightly bigger
The vape itself feels very similar between the two. The BM6000 lasts longer between changes and has a bigger battery capacity compared to the BM600. You can view the full range of Lost Mary pods, and which devices the pods are compatible with.
For vapers who want even more puff count from Lost Mary, the Nera 30K goes further with approximately 15,000 puffs per pod side and a full view screen. Our switching from disposables guide covers all the options if you're still working out what to go for.
