Lost Mary OS5000 Review: Why 5,000 Puffs Still Sells
A 13 mL, 650mAh disposable with no settings and the longest review record in this series.
6 min read
Key Takeaways
- Lost Mary rates the OS5000 at 5,000 puffs from 13 mL of e-liquid, which is about 385 rated puffs per mL.
- The battery is 650mAh with USB-C charging, behind a single mesh coil, and buyers say it outlasts the e-liquid rather than the other way round.
- Buyers disagree on whether the device shows its levels: one calls the battery display unique, two others say it tracks nothing.
- DirectVape lists 35 flavors, eight of them with Ice in the name.
- It still sells because it is small; next to the MT35000 Turbo it has a seventh of the rated puffs and a fraction of the bulk.
What the Lost Mary OS5000 Is
The Lost Mary OS5000 is a rechargeable disposable rated at 5,000 puffs from 13 mL of e-liquid, with a mesh coil and a 650mAh battery that charges over USB-C. It is one of the older designs in our disposables range, and it has outlived most of the devices that launched beside it. The reason is simple. It is small, it has no buttons and no settings, and the record of buyer reviews behind it is longer than almost anything else on the shelf. The question for you is whether a 5,000-puff rating still makes sense in a range that now runs to tens of thousands.
| Spec | Lost Mary OS5000 |
|---|---|
| Rated Puffs | 5,000 |
| E-Liquid | 13 mL |
| Battery | 650mAh |
| Coil | Mesh |
| Charging | USB-C |
| Flavors Listed | 35 |
Battery and Charging
A 650mAh cell behind 13 mL is a different balance from the big devices. Where a large dual mesh disposable needs its battery topped up many times, the OS5000's single mesh coil and smaller reserve mean fewer cycles before the e-liquid runs out. Lost Mary charges it over USB-C and publishes no charge time, so I will not estimate one.
Buyers describe the cell as the part that does not give out first. A buyer on elementvape.com writes: "Great flavor and has a solid battery life. Never got burnt until it was out of juice." That is the order you want: the e-liquid ends before the coil dries or the battery fails. The one battery complaint on the sheet is not about capacity. A buyer on ejuicedb.com writes: "needs a fluid and battery life indicator!...just saying!" I return to that below, because another buyer says the opposite.
E-Liquid and Flavor
At 13 mL and a 5,000-puff rating, Lost Mary's arithmetic is about 385 puffs per mL, far below the ratings the bigger devices claim per mL. Read that as an older, more conservative rating rather than a worse one. Buyers describe the device as lasting longer than its size suggests, and the longevity quotes below are the evidence for that.
DirectVape lists 35 flavors. The ice names are Acai Berry Storm Ice, Banana Raspberry Ice, Berry Crush Ice, Blue Razz Ice, Green Grape Ice, Peach Ice, Pineapple Duo Ice and Sakura Berry Peach Ice. The mint group is Forest Mint, Lemon Mint, Light Snoow Peppermint, Rose Sour Plum Mint and Strawberry Guava Mint. The lemonade and soda names are Black Lemonade, Raspberry Lemonade, Watermelon Kiwi Lemonade, Cherry Cola and Lemon Lime. Dessert and candy are Banana Split, Blueberry P&B Cloud and Blueberry Raspberry Gami. The rest are fruit blends, from Mexican Mango and Strawberry Watermelon to Mango Pomelo Dragon Fruit and Strawberry Apple Blackcurrant.
Taste is where the reviews split, and the split is by flavor rather than by device. On the Rose Sour Plum Mint, a buyer on vapordna.com writes: "The rose flavor is a bit too strong. If it was just plum I think it would be better." That is a complaint about a recipe, and it tells you more about that flavor than about the OS5000.
Draw, Airflow and the Screen
Lost Mary's facts with us list no airflow adjustment and no screen, so the OS5000 is a draw-activated device with one setting. A buyer on vapordna.com who went back to it sums up the draw and the size together: "lasts surprisingly long for a small vape. The only con is it doesn't track anything." That agrees with the ejuicedb.com buyer who wanted an indicator.
A buyer on vapesourcing.com, reviewing the Cosmic Edition, disagrees: "has consistent flavor and lasts very long. the battery display is very unique". I cannot settle that from the facts with us, which list no display. The likeliest reading is that the device shows something about battery state and nothing about e-liquid, and that buyers who want a full readout count that as nothing. Check the product page for Lost Mary's current wording before you decide.
What Buyers Say
The OS5000 has the longest written record of any device in this series, and the pattern is steady: buyers like the size, the draw and the flavor, and the complaints are about a specific flavor or about the lack of a readout. The elementvape.com buyer's "solid battery life" and the vapordna.com buyer's "lasts surprisingly long for a small vape" are the two sentences I would keep.
The critical notes are honest and short. The ejuicedb.com buyer who wanted an indicator gave three stars for it, and a different buyer on ejuicedb.com gave two: "All ok, but boring. Doesn't last enough." That buyer is right on the number. Against a range that now runs to tens of thousands of rated puffs, 5,000 is small, and anyone who has used a bigger device will notice. The rose complaint above is the other kind of criticism, and it is one you can avoid by picking a different flavor.
Where It Sits
Within the Lost Mary range on DirectVape the OS5000 is the small one. The MO5000 carries the same 5,000-puff rating in a different body, and the MT35000 Turbo sits at 35,000, seven times the rating. Within our 5,000-puff class the OS5000 is the Lost Mary with the longest review record on our sheet. If you want the Lost Mary flavors in the smallest body, this is the one; if you want the puff count, the MT35000 is the one.
Pick It If, Skip It If
Pick it if:
- You want a small, draw-activated device with no settings to learn.
- You want a long flavor list, 35 names, and you like to switch often.
- You want a long record of buyer reviews behind a purchase.
Skip it if:
- You want a readout of e-liquid and battery levels; buyers say it tracks nothing, or next to nothing.
- You have used a 20,000-puff or 35,000-puff device and want that span again; 5,000 will feel short.
- You want adjustable airflow, which the facts with us do not list.
The Verdict
The Lost Mary OS5000 is a 5,000-puff, 13 mL disposable on a 650mAh cell, and it still sells because it is small, simple and well documented. The buyers we can cite agree on the battery outlasting the e-liquid and on a draw that suits a small device, and the complaints are about the lack of a readout and, from one buyer, about it not lasting enough. Both complaints are fair, and both come with the size. If you want a pocket device and a wide flavor list, it earns its place; if you want days between refills, the MT35000 Turbo is the Lost Mary to look at instead.
