What the Screen on a Disposable Actually Shows
Battery, e-liquid and mode: what the display tells you, what it estimates and what it leaves to the label
5 min read
Key Takeaways
- A disposable's screen shows how much battery is left and how much e-liquid is left, and on a device with modes it names the mode.
- The battery reading is the one to trust; the e-liquid reading is the device's estimate, so look at the e-liquid too when you can.
- The Lost Mary MT35000 Turbo carries a display Lost Mary calls blend-in, behind a 35,000 puff rating, an 18mL of e-liquid and a 1000mAh battery.
- The RAZ LTX 25K carries a screen and adjustable airflow, behind a 25,000 puff rating, a 16mL of e-liquid and an 800mAh battery.
The screen on a disposable shows two things on nearly every model that has one: how much battery is left and how much e-liquid is left. On a device with more than one mode it also names the mode you are in, and nothing else on the screen matters to the draw.
That is the short answer, and it is worth having because the screen has become a line on every spec sheet without anyone saying what it is for. The two devices here both carry one: the Lost Mary MT35000 Turbo and the RAZ LTX 25K. Every figure is the maker's rating as our catalog lists it.
The Battery Reading
The battery reading is the reason screens arrived on disposables in the first place. A sealed device with a rechargeable cell needs some way to tell you it is time to charge, and a light that blinks once at the end was never much of a warning. A screen gives you a level you can read before you leave the house.
Treat this reading as the honest one. The device measures its own cell directly, so the figure on the screen tracks the charge as it drops and climbs again on the USB-C cable. On the MT35000 Turbo that cell is listed at 1000mAh, and on the LTX 25K it is listed at 800mAh.
The E-Liquid Reading
The e-liquid reading is the one people misread. A disposable has no gauge in the e-liquid; the figure on the screen is the device's running estimate of what is left, and it drifts the way any estimate drifts. It will tell you the e-liquid is getting low, and it is right about that, but it is not a measurement in the way the battery figure is.
So read it as a trend. When the device gives you a view of the e-liquid, look at the e-liquid as well; when it does not, treat a low e-liquid figure as a reason to have the next device on hand rather than as a countdown to the exact puff.
The Mode Line
On a device with modes, the screen is also where the mode shows. A mode is a coil setting the maker names; it changes what the coil does on a draw, and the name is the maker's, not a description of a benefit. Lost Mary lists Smooth Mode on the MT35000 Turbo, and its display shows e-liquid and battery levels during use; on a device with more than one mode, the same screen is where the mode name shows.
The mode line is the part of the screen worth checking when a device feels different from one day to the next. A mode that switched in a pocket reads differently in the hand, and the screen is how you find out before you blame the flavor.
What the Screen Does Not Show
It does not show the strength; that is on the label, and on both devices here the label reads 5%. It does not show the flavor, the puff rating or how many puffs remain in a countable way. It does not show the airflow setting on an adjustable device; on the LTX 25K the airflow control is on the body, and your lips tell you where it sits.
It also does not show how much e-liquid the device started with, which is where the catalog comes in. The MT35000 Turbo holds 18mL and the LTX 25K holds 16mL, so a half reading on one is a different amount of e-liquid from a half reading on the other.
The Two Devices, Side by Side
| Device | Screen | Airflow | Puff Rating | E-Liquid | Battery | Coil |
|---|---|---|---|---|---|---|
| Lost Mary MT35000 Turbo | Blend-in display, Lost Mary's term | Fixed | 35,000 | 18mL | 1000mAh | Dual mesh |
| RAZ LTX 25K | Screen | Adjustable | 25,000 | 16mL | 800mAh | Dual mesh |
Lost Mary's blend-in description means the display sits inside the body and shows e-liquid and battery levels during use, in the maker's own words on its site. RAZ fits the LTX 25K with a screen and pairs it with an adjustable airflow control, so on that device the screen reads the levels and the body sets the draw.
Which One for You
Pick the Lost Mary MT35000 Turbo if you want the larger numbers, 35,000 puffs, 18mL and 1000mAh, with a fixed draw and a display that stays out of the way until you use it. Pick the RAZ LTX 25K if you want the airflow control in your hand and are content with 25,000 puffs, 16mL and 800mAh. On either, read the battery figure as fact and the e-liquid figure as a trend.
FAQ
What Does the Screen on a Disposable Show?
Battery level, e-liquid level and, on a device with modes, the current mode; the MT35000 Turbo shows e-liquid and battery during use.
Is the E-Liquid Figure Exact?
No, it is the device's estimate, so on an 18mL or 16mL of e-liquid treat it as a trend and look at the e-liquid when you can.
Does the Screen Show the Nicotine Strength?
No, the strength is on the label, and both devices here are 5%.
Which of the Two Has the Larger Battery?
The Lost Mary MT35000 Turbo lists 1000mAh and the RAZ LTX 25K lists 800mAh.
