Lost Mary BM600 vs BM6000: What's the Difference?

The BM600 and the BM6000 are both rechargeable Lost Mary kits that take prefilled pods. The difference is size: the BM600 takes a small 2ml pod of about 600 puffs, and the BM6000 adds a 10ml refill container to its 2ml pod for up to 6,000 puffs a pack.

The Lost Mary BM600 kit is the small, simple one.

The Lost Mary BM6000 kit lasts far longer per pack and has a battery screen.

Lost Mary BM600 vs BM6000

The short answer: the BM6000 suits most vapers, because one pack lasts several days rather than one or two. The BM600 suits light vapers, anyone who likes to switch flavours often, and anyone who wants the smallest kit.

What Does BM600 and BM6000 Mean?

The number is the puff count: BM600 for about 600 puffs, and BM6000 for up to 6,000. There is no official meaning for "BM", so treat it as part of the model name.

The BM600 kit replaced the old single-use BM600, which was banned in the UK on 1 June 2025. The BM6000 was never a disposable in the UK: it launched in 2024 as a rechargeable kit.

How Does the Lost Mary BM6000 Work?

Each refill pack is a 2ml prefilled pod with a 10ml container that clips on below it. The container keeps the pod topped up as you vape, which is how one pack gives up to 6,000 puffs while the pod itself never holds more than the 2ml the UK allows.

To fit a new pack:

1. Remove the sticker and read it.
2. Remove the silicone from the device.
3. Push the container into the device.
4. Turn the kit upside down and shake it a few times until there are no bubbles in the container.
5. Start vaping.

New packs are in our Lost Mary BM6000 refill pods.

How Does the Lost Mary BM600 Work?

The BM600 takes one 2ml prefilled pod at a time, with no container. Setting up a new pod is two steps: pull out the top plug, then peel off the bottom sticker. When a pod is empty, pull it out and push in the next.

Pods come two to a pack in our Lost Mary BM600 refill pods.

How Many Puffs in a Lost Mary BM600 and BM6000?

About 600 puffs from each 2ml BM600 pod, the same as the old BM600 disposable, so 1,200 from a two-pod pack. Up to 6,000 puffs from a BM6000 refill pack, about ten times as many as one BM600 pod.

How Long Does a Lost Mary BM600 Last?

A 600 puff pod lasts about two to three days for a light vaper, one to two days for a moderate vaper, and under a day for a heavy vaper, going by the Lost Mary puff count guide.

How Long Does a Lost Mary BM6000 Last?

One BM6000 refill pack lasts about seven to ten days for a light vaper, five to seven days for a moderate vaper, and three to five days for a heavy vaper. One full charge of its battery is made to last the whole 12ml pack.

Kits from other brands with the same puff counts are in our 600 puff vapes.

The bigger kits are in our 6000 puff vapes.

How Much Nicotine Is in a Lost Mary BM6000 and BM600?

Both come in 20mg nic salt, which means 20mg of nicotine in every ml of e-liquid, the highest strength allowed in the UK. The BM6000 is also made in 10mg and 0mg, and we sell it in 20mg and 10mg. The BM600 is 20mg only.

For the 0mg BM6000 and the zero nicotine kits we sell instead, see is there a nicotine free Lost Mary.

Lost Mary BM600 and BM6000 Size

The BM600 is 65.4mm tall, 36.84mm wide and 17.26mm deep. The BM6000 is 100mm tall, 44mm wide and 22mm deep, so it is noticeably bigger and holds six times as much e-liquid per pack.

Charging the BM600 and BM6000

Both charge over USB-C. The BM6000 screen shows the battery as a percentage, and the BM600 light stays on while it charges and goes off when it is full.

Our guide on how to charge a Lost Mary covers both, with how long each takes.

Will 600 Puff Vapes Make a Comeback?

The Vaping Products Duty adds £2.20 for every 10ml of vaping liquid, with or without nicotine. It applies to stock made in or brought into the UK from 1 October 2026, and older stock can be sold until 31 March 2027, so shelf prices will change as duty-paid stock comes through. From 1 April 2027, every vape sold in the UK must carry a duty stamp.

On duty-paid stock, that is £2.64 of duty on a 12ml BM6000 pack and 88p on a two-pod BM600 pack. The BM6000 still gives far more puffs per pack, but the BM600 will be the smaller spend each time you buy, and in our view that will win some vapers back to the 600 puff size.

Our vape tax guide explains the duty in full.

Our 600 puff comeback post sets out the case.

Which Lost Mary Kit Should You Get?

• Get the BM6000 if you vape most of the day, want a battery screen, or want 10mg. In our view it is the better pick for most vapers.
• Get the BM600 if you vape lightly, like changing flavour every day or two, or want the smallest kit.
• More than 6,000 puffs: The Lost Mary Nera 30K takes bigger pods again.

Both kits share many flavours, and our Lost Mary flavours list ranks the best sellers for each.

Every kit and pod is in our Lost Mary rechargeable vapes.
