How Long a Disposable Vape Actually Lasts, Brand by Brand
Every disposable carries a puff rating on the box, and almost nobody gets that many puffs. This guide turns the ratings for Geek Bar, Foger (often spelled Fogger), RAZ, Lost Mary, Flum, Off Stamp, Nexa, Lost Angel, Dojo and Olit Hookalit into days, using the e-liquid and battery specs from our own product pages, and explains what actually ends a device: the tank, not the counter. Published September 17, 2026.
Quick Verdict
Days = rated puffs divided by your daily puffs. At about 300 puffs a day, a 15,000-puff device such as the Geek Bar Pulse 15K lasts around 50 days on paper; a 50,000-puff device such as the Geek Bar Pulse X2 50K or RAZ RX 50K lasts around 167. At 600 a day, halve those. Real numbers run shorter because the ratings assume short lab draws; a moderate Pulse 15K user typically sees 10 to 14 days.
The battery does not decide how long a disposable lasts. Every current device from these brands recharges, nearly all over USB-C, so the battery only decides how often you plug in. The e-liquid decides when it is finished. The one exception to the "battery is reusable" idea is the pod systems: on a Foger Switch Pro, Geek Bar Mate 60K or Off Stamp X Cube you keep the battery and replace the pod.
Charge times run 30 to 90 minutes on almost everything we stock, and about 2.5 hours on the largest Olit Hookalit cell. Sealed shelf life, where a brand publishes one, is 12 to 18 months.
The Short Answer: Puff Rating Divided by Your Daily Puffs
Ask ten people how long a disposable vape lasts and you will get ten answers, because the question hides a second one: how much do you vape? The rating on the box is a puff count, not a day count. The manufacturer fires the device on a machine at a fixed cadence, typically short draws of one to one and a half seconds with a pause between them, and counts how many puffs it takes to empty the tank. That number goes on the packaging. Your job is to divide it by the number of puffs you take in a day.
Three reference cadences cover most people. A light user takes around 150 puffs a day, a few short sessions spread across the day. A moderate user takes around 300, which is a puff every few minutes through the waking hours. A heavy user takes 600 or more, chain-vaping through multiple sessions. On a 25,000-puff device, those cadences give you roughly 167, 83 and 42 days on paper. The table further down runs the same math for 57 models at 300 and 600 puffs a day.
The catch is that the paper number is an upper bound. A real draw is usually longer than the lab draw. Our Geek Bar guide measured that a three-second pull uses about one and a half times the e-liquid of a two-second pull, and many people pull for three to four seconds when they want a stronger hit. Boost or Pulse modes on the newer devices roughly double consumption per draw. So a moderate user who is "supposed" to get 50 days from a Pulse 15K by the math typically sees 10 to 14, and a heavy user sees five to seven. The math tells you the ranking between devices; your own draw tells you the actual date it runs dry.
One more clarification, because it shows up in the search data: a disposable vape from any of these brands will not get you high. They contain nicotine salt e-liquid, or in the zero-nicotine editions no nicotine at all, and no THC or other cannabinoids.
How Long Do Geek Bars Last? Pulse 15K, Pulse X 25K, Pulse X2 50K and Mate 60K
Geek Bar is the most-asked brand for this question, and the answer depends on which of four current mainline devices you are holding. The Geek Bar Pulse 15K holds 16 mL of 5 percent e-liquid on a 650 mAh battery and is rated 15,000 puffs in Regular Mode or 7,500 in Pulse Mode. The Geek Bar Pulse X 25K steps up to 18 mL and 820 mAh, rated 25,000 Regular or 12,500 Pulse. The Geek Bar Pulse X2 50K doubles the rating again to 50,000 puffs on a rechargeable mesh-coil platform; Geek Bar has not published its tank size or battery capacity on our spec sheet, so those cells read "not published" in the table.
The Geek Bar Mate 60K Kit is a different animal. It is a pod system: a 900 mAh rechargeable base plus a 15 mL pod that carries its own 200 mAh cell, rated 60,000 puffs in Regular Mode or 30,000 in Pulse Mode per pod. When the pod is empty you snap on a new one and keep the base. So "how long does a Geek Bar Mate last" has two answers: the pod lasts 60,000 rated puffs, and the base lasts as long as you keep buying pods. The query "how long do the Geek Bar Mate pods last by itself" usually means the pod off the base; the pod's 200 mAh cell is meant to feed the system during use, not to run the pod alone for a day, and Geek Bar does not publish a standalone runtime for it.
Turning ratings into days, the Geek Bar site we run uses a 200-puff moderate day and gets about 7 days for the Pulse 15K, 12 for the Pulse X 25K, 25 for the CLR 50K and 30 for a Mate 60K pod. At the 300-puff cadence used in this article the on-paper numbers are 50, 83, 167 and 200 days respectively, and at 600 a day they halve. The gap between the 7-day figure and the 50-day figure is not a contradiction; the first is a realistic estimate that bakes in long draws and Pulse Mode, the second is pure division. If your Pulse 15K is consistently lasting 5 to 7 days, the Geek Bar guide is blunt about the cause: long draws of 2.5 seconds or more, time in Pulse Mode, or back-to-back puffs that keep the coil hot. It is not a defective device.
"How long should a Geek Bar Pulse X last" gets the same treatment. Rated 25,000 puffs in Regular Mode, it should run 16 to 18 days for a moderate user and 10 to 12 for a heavy one according to the customer feedback behind our Geek Bar guide. Flip it into Pulse Mode for most of the day and expect roughly half. The Pulse 2 25K and Skyview 25K carry the same 25,000 rating; the Skyview holds 16 mL on 800 mAh.

How Long Does a Foger (Fogger) Last, With and Without the Battery
Foger is spelled "Fogger" in a large share of searches, so this section uses both. The brand sells two devices with very different battery stories. The Foger Bit 35K is a conventional disposable: 21 mL of e-liquid, a sealed 850 mAh battery, rated 35,000 puffs in Norm (Eco) mode or 25,000 in Boost. At 300 puffs a day it lasts about 117 days on paper, 58 at 600 a day. The Foger battery guide on the brand site reports heavy direct-to-lung users in Boost finishing a Bit 35K in 7 to 10 days and moderate mouth-to-lung users in Eco getting three weeks or more.
The Foger Switch Pro 30K Kit is a pod system, and it is the reason "how long does a Fogger last without the battery" is such a common question. The kit is an 850 mAh magnetic charging dock plus a pre-filled pod. Each Switch Pro pod holds 19 mL of e-liquid, a 1.0 ohm dual mesh coil and its own 200 mAh cell, and is rated 30,000 puffs in Normal mode or 18,000 in Boost. The dock is the part you keep. The pod is the part you use up.
So, without the battery: a Switch Pro pod pulled off the dock keeps firing on its own 200 mAh cell for short sessions. The Foger battery guide calls it a stopgap, enough to keep vaping while the dock charges, not a day of standalone runtime, and Foger does not publish a puff count for the pod cell alone. What does not change is the e-liquid. The pod is still rated 30,000 puffs from 19 mL whether it spends its life on the dock or off it; the battery only decides how many of those puffs you can take before plugging in. Snap it back on the dock and the system charges the pod cell as normal. For the Bit 35K the phrase does not apply at all: the battery is integrated, and at 0 percent the device just waits for USB-C. The e-liquid keeps, and recharge cycles do not reduce the puff capacity.
"How long do Foger batteries last" is a per-charge question and a lifetime question. Per charge, the Bit 35K's 850 mAh supports roughly 1,200 to 1,800 puffs in Eco or 800 to 1,200 in Boost, and refills from empty in about 35 to 50 minutes over USB-C. A Switch Pro dock supports roughly 1,500 to 2,000 puffs per charge. Over a lifetime, the dock behaves like any lithium cell: after about 300 charge cycles it holds around 80 percent of its original capacity. For a dock that has been through six or more pods, slower days between charges are wear, not a fault. Boost mode is the most common reason a Foger seems to die fast; it draws roughly 40 percent more current per puff than Eco. If you want the head-to-head with Geek Bar, our Geek Bar vs Foger comparison covers flavor as well as hardware, and the Foger brand page lists both devices and every pod flavor.
How Long Does a RAZ Vape Last?
RAZ runs a clean ladder of puff counts, which makes the math easy. The RAZ TN9000 holds 12 mL on a 650 mAh battery and is rated 9,000 puffs: about 30 days at 300 puffs a day, 15 at 600. The RAZ DC25000 holds 18 mL on 800 mAh for 25,000 puffs, about 83 days or 42. The RYL Classic 35K holds 16.5 mL on 820 mAh for 35,000 puffs, about 117 days or 58. The RAZ RX 50K holds 19 mL on 1,000 mAh for 50,000 puffs, about 167 days or 83. The zero-nicotine LTX 25000 keeps the 25,000 rating on the same 20 mL.
The RAZ VUE 50K is the brand's pod system: a 13 mL pod with a 420 mAh cell riding on a 900 mAh base, rated 50,000 puffs per pod. As with the Foger Switch Pro, the pod is the consumable and the base is the part you keep. Note the e-liquid figure, because it tells you something the puff rating does not: 13 mL rated for 50,000 puffs means each rated puff is much smaller than on a TN9000, where 12 mL is rated for 9,000. Real draws are not that small, which is why high-puff devices tend to disappoint people who expected them to last five times longer than a 9K. RAZ does not publish charge times; the cells run 650 mAh on the TN9000, 800 on the DC25000 and RX 50K, 820 on the RYL Classic 35K and 900 in the VUE base, all charged from a 5V/1A adapter. The RAZ brand page has every device and flavor.
Lost Mary, Flum and Off Stamp: Days per Device
Lost Mary spans the widest range of any brand in this table, from the 5,000-puff MO5000 (13.5 mL, 500 mAh) and OS5000 (13 mL, 650 mAh) up to the NERA Fullview 70K Kit, which ships with an 800 mAh charging device and two 12 mL pods rated 35,000 puffs each. In the middle sit the MT15000 Turbo (16 mL, 600 mAh, 15,000 puffs), the MO20000 Pro (18 mL, 800 mAh, 20,000), the Quasar OS25000 (20 mL, 850 mAh, 25,000), the Losgal MC25000 (16 mL, 750 mAh, 25,000), the Lost Mary MT35000 Turbo (18 mL, 1,000 mAh, 35,000 in Smooth mode or about 20,000 in Turbo), the coilless Ultrasonic 35K (20 mL, 800 mAh, 35,000) and the VIZ 55K (16.7 mL, 55,000). A 5K Lost Mary lasts about 17 days at 300 puffs a day; the MT35000 lasts about 117; a single NERA pod about 117. Lost Mary's own instructions put a full charge at 30 to 60 minutes depending on model, and the MT35000 line advertises a 10-minute fast charge.
Flum tells the same story in a different accent. The original Float and Gio hold 8 mL on 800 mAh for 3,000 puffs, about 10 days at 300 a day. The Pebble holds 14 mL on 600 mAh for 6,000 puffs, about 20 days. The Mello 20K (15 mL, 650 mAh) is rated 20,000, about 67 days. The UT Bar Pro 25K (15.5 mL, 760 mAh) is rated 25,000, about 83 days. The UT Bar Pro 50K holds 16 mL on 760 mAh and is rated 50,000 puffs with two flavors in one device, about 167 days on paper, and the Float Mello Pro 50K reaches the same rating from a much larger 30 mL tank on 1,000 mAh. The Clear Tank 50K and the Float Ryzo 60K pod kit are rated 50,000 and 60,000 respectively, with tank and battery not published on our spec sheet. Flum's charging guide puts the Mello 20K and UT Bar Pro 25K at 45 to 60 minutes from empty and the 50K devices at 75 to 90.
Off Stamp only makes pod systems, so every Off Stamp answer is a per-pod answer. The SW9000 pod holds 13 mL for 9,000 puffs, the SW16000 pod holds 17 mL for 16,000, the X Cube 25K pod holds 18 mL for 25,000 on an 1,100 mAh base, and the X Cube Crystal 35K pod holds 17 mL for 35,000 on a 1,000 mAh base. At 300 puffs a day that is roughly 30, 53, 83 and 117 days per pod. The pod has no charging port; all the power lives in the base, which refills from empty in about 45 minutes and can charge with the pod on or off. Off Stamp is also one of the few brands to publish a shelf life: sealed pods are good for roughly 12 to 18 months from the production date on the box, stored at room temperature out of direct sun.
Nexa, Lost Angel, Dojo and Olit Hookalit
Nexa's five devices cluster at the top of the puff ladder. The Pro 30K holds 15 mL on 900 mAh for 30,000 puffs. The Flex 35K (18 mL, 1,000 mAh) and Pix 35K (16 mL, 800 mAh) are both rated 35,000. The Ultra 50K II (20 mL, 900 mAh) and Ultra 50K Invisa (20 mL, 800 mAh) are rated 50,000. That is 100, 117, 117, 167 and 167 days at 300 puffs a day, or half at 600. Nexa's FAQ puts a full USB-C charge at about 60 to 90 minutes depending on model.
Lost Angel sells two: the Sphere 35K, a sealed disposable with 20 mL on 1,000 mAh rated 35,000 puffs, and the Lost Angel Mate 50K Kit, a pod system with a 1,200 mAh base and 20 mL pods rated 50,000. Both charge from empty in 30 to 45 minutes on a 5V phone adapter; the brand advises against fast-charge bricks. Dojo, the disposable line backed by Vaporesso, runs the iMate X 20K Kit (15 mL pods with a 400 mAh cell on a 900 mAh base, 20,000 puffs per pod), the Sphere S 40K (1,100 mAh, 40,000 puffs, about two hours to charge at 5 W) and the PUREX 60K (60,000 puffs; tank and battery not published). The PUREX is the longest-rated sealed disposable in this table at 200 days on paper at 300 puffs a day.
Olit Hookalit is the outlier, and it is worth understanding why before you compare it with anything else. These are hookah-style devices at lower nicotine strengths with enormous tanks: the Hookalit 40K carries 40 mL on 1,300 mAh at 3.5 percent, the Olit Hookalit Pro 60K carries 30 mL on 1,500 mAh at 3.5 percent, and the Mega 200K carries 80 mL on 1,700 mAh at 0.35 percent. On paper the Mega 200K lasts 667 days at 300 puffs a day, but nobody uses a hookah pen at a cigarette cadence; it is built for long shared sessions where puff counts run far higher. The batteries are the largest in the table and take the longest to fill: about 60 minutes on the 40K, 90 on the Pro 60K and 2.5 hours on the Mega 200K from out of the box.
Every Model We Stock: Puffs, mL, mAh and Days
The table below pulls rated puffs, e-liquid capacity and battery capacity from our own product spec sheets for 57 models across ten brands. The two day columns are simple division: rated puffs divided by 300, and rated puffs divided by 600. They are ceilings, not predictions. Where a brand has not published a figure on our spec sheet the cell says "not published" rather than guessing. For pod systems the puff rating and e-liquid are per pod, and the battery lists the base and, where the pod has its own cell, the pod.

Two patterns jump out. First, e-liquid does not scale with puff count. A 9,000-puff RAZ TN9000 holds 12 mL; a 50,000-puff RAZ VUE pod holds 13 mL. The extra puffs come from smaller rated draws, lower-power modes and more efficient coils, not from five times the liquid, which is why the day gap between a 9K and a 50K in real use is nowhere near five to one. Second, battery capacity has nothing to do with total life on any of these devices, because every one of them recharges. A 650 mAh Pulse 15K and a 1,500 mAh Burj 80K both run until the tank is dry; the Burj just needs fewer trips to the cable per mL.
Why E-Liquid Runs Out Before the Puff Counter Does
If you take one thing from this article, take this: the tank ends the device, and the puff rating is a description of the tank under ideal conditions. A 16 mL Pulse 15K rated 15,000 puffs is really saying that 16 mL vaporized in lab-length draws produces about 15,000 of them. Every deviation from the lab draw pulls the real count down. Longer draws vaporize more liquid per puff. Deeper direct-to-lung inhales pull more air across a hotter coil. Back-to-back puffs keep the coil hot, and a hot coil vaporizes more per second than a cool one. Cold storage can cause condensation that wastes e-liquid through the airway, and a hot car can cause slight expansion and leakage.
Modes are the biggest single lever. Pulse Mode on a Geek Bar, Boost on a Foger or Lost Mary Turbo runs the same coil at higher wattage, and the manufacturers rate those modes at roughly half the puffs: 7,500 versus 15,000 on the Pulse 15K, 18,000 versus 30,000 on a Foger Switch Pro pod, about 20,000 versus 35,000 on the Lost Mary MT35000 Turbo. Leave the device in the high-power mode all day and your 83-day math becomes 42-day math before you account for anything else.
This is also why the mL column deserves more attention than the puff column when you are comparing brands. Two devices with the same 50,000 rating can hold 13 mL or 30 mL. If your draws are longer than the lab draw, and they are, the 30 mL device will outlast the 13 mL device by a wide margin even though the box says they are equal. When you compare, say, the Flum Float Mello Pro 50K (30 mL) with the RAZ VUE 50K pod (13 mL), the tank size is the honest number.
Battery: How Long a Charge Lasts and How Long It Takes to Charge
Because every device in this table is rechargeable, battery life is a question of convenience rather than lifespan. The useful numbers are puffs per charge and minutes per charge. Foger publishes the clearest per-charge figures: 1,200 to 1,800 puffs per charge on a Bit 35K in Eco mode, 800 to 1,200 in Boost, and 1,500 to 2,000 per charge on a Switch Pro dock. Geek Bar's guide puts the first recharge for a light-to-moderate Pulse user on day four to seven. Most people on most devices end up charging every one to three days.
Charge times cluster tightly. Geek Bar: about 30 to 45 minutes, with the Pulse 15K at the fast end and the CLR 50K at 45 to 60. Foger Bit 35K: 35 to 50 minutes. RAZ: not published; 650 to 900 mAh cells on a 5V/1A adapter. Lost Mary: 30 to 60 minutes depending on model, with a 10-minute fast charge on the MT35000 line. Flum: 45 to 60 minutes on the 20K and 25K, 75 to 90 on the 50K devices. Off Stamp X Cube base: about 45 minutes. Nexa: 60 to 90 minutes. Lost Angel: 30 to 45 minutes. Dojo Sphere S: about two hours at 5 W. Olit Hookalit: 60 minutes on the 40K, 90 on the Pro 60K, 2.5 hours on the Mega 200K. All of them charge from a plain 5V phone adapter, nearly all over USB-C; several brands note that a high-wattage laptop or GaN brick does not charge faster because the device caps its own draw, and Lost Angel and Foger both recommend against them.
Two habits keep a battery healthy for the life of the tank. Unplug when the indicator shows full rather than leaving it on the cable overnight, and let a device that has been in a cold car warm to room temperature before charging. If a Geek Bar has sat fully drained for weeks it may have entered deep-discharge protection; the charging guide says to leave it on the cable for 5 to 10 uninterrupted minutes and check again, and to treat a screen that stays dark after 15 minutes as an end-of-life cell.
Empty Tank, Dead Battery, Blinkers and the "On 0" Question
The two failure modes feel similar in the moment (you draw and get nothing worth having) but they present differently, and only one of them is fixable. A dead battery gives you no vapor at all. The screen is dark or shows the battery at 0 percent, or on a device with an LED the light blinks when you draw and then goes out. Plug it into USB-C: if the charging indicator lights up and a normal draw comes back after a few minutes, the tank was fine all along. On a screen device you can confirm it before you even plug in, because the e-liquid bar will still show liquid while the battery bar shows nothing.
An empty tank is the opposite. The device fires, the light or screen responds normally, and vapor still comes out, but it is thin, the flavor goes flat, and within a few draws it turns to the dry, scorched taste of a coil with no liquid on it. On a screen device the e-liquid bar reads zero. Charging changes nothing. That taste is the signal to stop; there is no trick that gets more out of a dry coil, and pulling harder only makes it worse. On a pod system this is the moment to swap the pod, and Off Stamp's instructions describe exactly this transition as the pod cue.
The awkward middle case is a device that fires weakly with a low but not empty battery. Lithium cells deliver less power as they drain, so the last 10 or 15 percent of charge can feel like a fading tank. If the e-liquid bar still shows liquid, charge first and judge afterwards.
A "blinker" is slang for a draw held long enough that the device hits its automatic cutoff and the indicator flashes to tell you it stopped firing. The cutoff exists to protect the coil and the battery. Geek Bar does not publish the exact cutoff duration on our spec sheet, so we will not invent one; what matters for this article is what a blinker costs you. The Geek Bar guide measured a three-second draw at about one and a half times the e-liquid of a two-second draw, and a blinker runs well past three seconds. Take a few every day and your 50-day math is gone. The device is behaving as designed.
"How long does a Geek Bar last on 0" has two honest readings and we will answer both. If you mean the 0 mg version, the Geek Bar Pulse Zero Nicotine uses the same 16 mL tank and 650 mAh cell as the Pulse 15K and carries the same 15,000 puff Regular, 7,500 puff Pulse rating, so it lasts exactly as long. RAZ's LTX 25000 Zero Nicotine and Lost Mary's MT35000 Turbo Zero Nicotine likewise keep their nicotine versions' ratings. If you mean the battery reading 0 percent, the device stops firing and waits. Nothing is lost: the e-liquid stays in the tank, a 30 to 45 minute charge brings the Geek Bar back, and the puff capacity is unaffected by how many recharge cycles the cell has been through. The related query "how long after zero percent do Geek Bar vapes last" is really asking about the e-liquid gauge. When that bar reads zero, treat the device as finished; the flavor is about to go flat and then scorched, and there is nothing to recover.
Shelf Life of a Sealed Disposable
A sealed disposable does not last forever in a drawer, and the limiting part is the battery, not the liquid. Two brands in this table publish a number. Foger rates a sealed, factory-fresh Bit 35K or Switch Pro Kit for 12 months from the manufacturing date printed on the device, and warns that beyond that the battery percentage at first use may be reduced. Off Stamp rates sealed pods at roughly 12 to 18 months from the production date on the box. The other brands have not published a figure, and we do not extrapolate.
Storage rules are the same across brands: room temperature, out of direct sun, away from the cold car and the hot dashboard. Foger's guide adds two lithium-specific notes for the reusable Switch Pro dock, which is the one component you actually keep long term: store it at 60 to 80 percent charge rather than full if it will sit for months, and do not let it run to 0 percent before recharging. Geek Bar's charging guide notes that a device that has sat fully drained for weeks can enter deep-discharge protection and may need 5 to 10 minutes on the cable before it shows any sign of life. If you buy in multiples, use the oldest first, and expect a device that has waited a year to arrive with less battery in it than one that shipped last week.
