Lost Mary BM600 vs BM600S: What’s the Difference?
The Lost Mary BM600 and BM600S are compact disposable vape devices designed for adult smokers and vapers who want a simple alternative to traditional cigarettes. Both belong to the same popular BM range, share a similar slim format, and are available in multiple fruit, beverage, and cooling flavours.
Their names are easy to confuse because both devices are generally associated with around 600 puffs and a prefilled 2ml e-liquid capacity. The important distinction is how each model delivers its vapour, how it handles the final part of its e-liquid supply, and whether it can be recharged.
The best choice depends on whether you prioritise maximum simplicity or a little more flexibility during use. Product specifications can vary by market, so check the individual listing for the exact nicotine strength, flavour, and pack information before ordering.
What the BM600 offers
The original Lost Mary BM600 is a draw-activated disposable vape. There is no button to press, no tank to fill, and no replacement coil to install. Simply inhaling through the mouthpiece activates the device, making it familiar to people moving from cigarettes or using disposable vapes for the first time.
The BM600 typically contains 2ml of nicotine salt e-liquid and is marketed for approximately 600 puffs. Its compact body is easy to carry, while the integrated battery is intended to last through the prefilled liquid. Once the e-liquid or battery is depleted, the entire device is replaced.
Nicotine strengths often depend on regional rules. In the UK and other regulated markets, the BM600 is commonly sold with nicotine salt at a legal strength such as 20mg/ml, while some markets may offer nicotine-free or different-strength versions. Always use the product information supplied for your location.
How the BM600S changes the experience
The BM600S keeps the straightforward disposable design but adds a rechargeable battery, usually through a USB-C charging port. This means the device can be topped up if the battery runs low before all the e-liquid has been used. Charging does not refill the liquid; it simply helps the built-in battery continue operating.
A rechargeable design can make the BM600S more practical for heavier users or for anyone who wants to avoid discarding a device because of a prematurely depleted battery. It also gives the device a little more consistency toward the end of its usable life, provided it is charged with suitable equipment and handled according to the manufacturer’s instructions.
The BM600S is also commonly associated with an updated mesh coil. Mesh heating can produce a smoother draw, more even vapour, and clearer flavour compared with a basic coil, although the result depends on the flavour, puff length, airflow, and individual preference. The “S” model should therefore be viewed as an updated version rather than a completely different type of vape.
Comparing specifications and daily use
Both devices are generally mouth-to-lung vapes, producing a cigarette-like draw rather than the large clouds associated with open-system kits. Their small size and prefilled format make them convenient for travel, short outings, and situations where carrying e-liquid and accessories would be inconvenient.
The advertised puff count is an estimate rather than a guarantee. Longer or deeper inhalations use more e-liquid per draw, so actual use may be lower than the stated figure. Flavour intensity can also change as the liquid level falls, particularly if the device is used repeatedly without pauses.

Exact specifications, nicotine levels, and available flavours may differ between regions. A genuine product listing should clearly state the capacity, strength, ingredients, and regulatory information.
Flavour and vapour differences
The BM600 is often chosen for its uncomplicated performance. Its standard coil delivers a familiar level of vapour and flavour, with options that may include berry blends, tropical fruit, menthol, icy profiles, and sweet drink-inspired combinations. The draw is generally designed to be discreet and controlled.
The BM600S may feel slightly more responsive because of its mesh coil and rechargeable power source. Mesh heating distributes heat across a broader surface, which can support a more saturated flavour profile. Some users may notice a fuller taste or smoother vapour, while others may prefer the lighter, simpler character of the original BM600.
Neither device is intended to be refilled or modified. If a burnt taste develops, the vapour becomes unusually weak, or the device stops producing vapour after charging where applicable, it should be disposed of responsibly rather than opened or repaired.
Which model suits different users
The BM600 is a strong match for occasional users who want a ready-to-use device with as little maintenance as possible. It is also suitable for people who prefer a genuinely disposable format and do not want to remember a charging cable. Once the device reaches the end of its life, it can be replaced with another flavour or nicotine strength.
The BM600S makes more sense for users who take frequent puffs throughout the day, travel for longer periods, or have experienced a disposable device running out of battery before its liquid. USB-C charging provides added flexibility, though it means carrying or accessing a suitable cable when needed.
Flavour choice is just as important as the model name. Someone who prefers a cool menthol or crisp fruit profile may find the same flavour more noticeable on the BM600S, while a sweeter or stronger profile can feel satisfying on either device. Reviewing the available product information can help clarify the retailer’s range and authenticity standards.
Practical points before buying
Both models should be purchased only from a reputable source. Check that the packaging is sealed, the product information is clear, and the device corresponds with the listed nicotine strength and capacity. Genuine Lost Mary products should also have appropriate labelling for the market where they are sold.
Keep nicotine products away from children and pets, and store devices in a cool, dry place. Do not expose them to extreme heat, water, or unnecessary pressure. The BM600S should be charged only with compatible equipment, never left charging unattended, and not used if the casing or charging port appears damaged.
Nicotine is addictive, and these products are intended for adults who already smoke or use nicotine. Non-smokers, pregnant people, and minors should not use them. Anyone trying to reduce nicotine intake should pay attention to the strength selected rather than assuming that a higher puff count means a stronger product.
A simple buying checklist
- Choose the BM600 if you want a no-charging, ready-to-use disposable vape.
- Choose the BM600S if USB-C recharging and a mesh-coil draw are more valuable to you.
- Check the listed nicotine strength, e-liquid capacity, and flavour before ordering.
- Confirm that the device is genuine, sealed, and approved for sale in your market.
- Dispose of used vapes through an appropriate recycling or electronic-waste route.
The BM600 and BM600S are close relatives, but their different battery and coil arrangements give them distinct advantages. The BM600 focuses on immediate simplicity, while the BM600S adds rechargeable convenience and a potentially richer draw. Review the available flavours and specifications, then place your selected genuine product in the shopping cart when you are ready to order.
