What the Lost Mary MO20000 Pro Is
The MO20000 Pro is the step up from the MT15000 Turbo in Lost Mary's range. It is a sealed body with 18 mL of e-liquid, an 800mAh rechargeable cell, a dual mesh coil and an adjustable airflow control, and Lost Mary rates it at 20,000 puffs. We added it to our catalog in August 2024. The MO20000 Pro product page carries the 30 flavors, and the device sits in our 10,000-plus puff class near the top of the Lost Mary range, below the MT35000 Turbo.
| Spec | Catalog Value |
|---|---|
| Rated Puffs | 20,000 |
| E-Liquid | 18 mL |
| Battery | 800mAh |
| Coil | Dual mesh |
| Airflow | Adjustable |
| Charging | USB-C |
| Flavors Listed | 30 |
Battery and Charging
The cell is 800mAh and charges over USB-C. That is the larger of the two cells in the Lost Mary Turbo and Pro pair, against the 600mAh in the MT15000 Turbo, and it is feeding 18 mL of e-liquid rather than 16. You will still recharge it before the liquid runs out; the cell is sized to be topped up, and Lost Mary does not publish a charge time.
Battery is a theme in 11 of 113 reviews. A buyer on vapordna.com writes, "This item has lasted longer than some 50k - 70k puffs vape. The flavor is great, battery is great." That is a comparison against a buyer's other devices, not a measurement, and we pass it on as such. The charging complaint on the sheet is the one you will read in the buyer section below, and it is about frequency rather than failure.
E-Liquid and Flavor
The body holds 18 mL of e-liquid. Against the 20,000-puff rating that is about 1,111 rated puffs per mL, Lost Mary's arithmetic rather than anyone's count. The 30 flavors on the catalog list are mostly fruit and fruit ice: Blue Razz Ice, Watermelon Ice, Strawberry Ice, Pineapple Ice and Sour Apple Ice carry the ice name outright, and Mango Twist, Tropical Punch, Strawberry Kiwi and Pear Drop are the uncooled fruit group. Beverage names sit beside them, Arizona Ice Tea, Dragon Drink and Pina Colada, with Rainbow Sherbet and Grape Jelly on the dessert side. Luxury Tobacco, Peppermint and Miami Mint are the non-fruit options, and Pure, Deep Purple and Red Wave are the names that do not say what they taste like.
On the sheet, Blue Baja Splash is the flavor buyers name most, four times, followed by Watermelon Ice at three and Tropical Punch, Miami Mint, Luxury Tobacco and Pear Drop at two each. Flavor is raised in 57 of 113 reviews and taste in 16, so it is the subject buyers return to more than any other. The verdicts on Blue Baja Splash are not all one way, and the clearest dissent is quoted below.
Draw, Airflow and the Screen
Airflow is adjustable, so you open the intake for a looser draw or close it for a tighter one, and the dual mesh coil underneath stays the same. That control is the clearest hardware difference between this device and the MT15000 Turbo, whose airflow is fixed. Our catalog does not record a screen on the MO20000 Pro, so the table leaves that row out, though buyers describe reading a battery readout on theirs.
A buyer on vapesourcing.com describes the control plainly: "I love the adjustable airflow on the bottom; it goes from a tight MTL to a loose draw perfectly." Smooth is the word that recurs for the draw across the sheet, in the 9 reviews that raise it, and none dated before this review call it harsh.
What Buyers Say
The battery complaint is about how often you charge rather than whether it holds. A buyer on ejuicedb.com writes, "The charge doesn't seem to last long enough though. Just have to recharge it," and still rates the flavor well. Read that beside the vapordna.com report above and the spread is wide: how long a charge lasts depends on how hard you draw, and the 800mAh cell is the same in both accounts.
The puff rating draws its own kind of hedge. A second buyer on vapesourcing.com writes, "I will continue to buy it even though it's only 20k puffs," which tells you two things at once: 20,000 is now a middling number in this class, and this buyer does not mind. We treat 20,000 as the maker's rating, and buyers who like the device treat it the same way.
The look divides people. A buyer on elementvape.com writes, "As far as the look its a little flashy for me but the flavor and battery life are fantastic," which is the shape of most of the four-star and five-star reviews on the sheet: a reservation about the body, no reservation about the flavor.
And on the most-named flavor, a buyer on perfectvape.com is blunt: "My least favorite(that I've tried so far) is the Blue Baja Splash. It's more minty than anything." Four buyers name it and not all of them for the same reason, so if you want a straight fruit profile, that is the one to read up on before you choose it.
Where It Sits
Inside the Lost Mary range the MO20000 Pro is the step up from the MT15000 Turbo: 18 mL against 16, 800mAh against 600, 20,000 rated puffs against 15,000, and adjustable airflow against fixed. Above it the MT35000 Turbo carries a higher rating, and the OS5000 is the pocket size at the other end. If the MT15000 is the middle of the range, the Pro is the one you pick when you want the extra mL and the airflow control.
Pick It If, Skip It If
Pick it if:
- You want adjustable airflow and an 800mAh cell in a Lost Mary.
- You want the 18 mL and 20,000 rating rather than the MT15000's 16 mL and 15,000.
- You want a tobacco or peppermint option on the same list as the fruit ice.
Skip it if:
- You want a plain body; more than one buyer calls this one flashy.
- You are chasing the highest rating on the shelf; one repeat buyer calls 20,000 "only 20k puffs" and buys it anyway.
- You want the smaller body of the 5,000-class devices.
The Verdict
From the catalog, the maker's rating and 113 reviews on our sheet, 107 of them rated and averaging 4.72 out of 5, the MO20000 Pro reads as the Lost Mary to pick when you want the bigger numbers and the airflow dial. The complaints on the sheet are mild and specific: charge it more than you would like, and read up on Blue Baja Splash before you order it. Against that, flavor and the draw get steady praise, and the 18 mL and 800mAh figures are a real step over the MT15000 Turbo.
