What the 4-in-1 Layout Actually Changes
The last three weeks I have kept this device on the desk and switched chambers between orders, so I am writing from the device rather than from the supplier sheet. It is not a bigger version of an ordinary disposable. Four sealed 16 ml chambers sit inside one body, each with its own coil and its own airway, and a rotating mouthpiece decides which one is live. That single change is what the rest of this page is about: what the arrangement gives you, what the arithmetic behind 120,000 really looks like, which of the ten flavour sets to stock, and what our own specification sheet does not tell you.
The practical difference appeared on day one. I used to carry three devices to cover a morning of sweet profiles and an evening of ice, and two of them ended up half empty in a drawer. Here, one body does the work and nothing sits half used. The URO brand range now runs this 4-in-1 alongside the smaller UOR models, and the same puff-count class is collected under 120k puffs.
Inside the Device: Four Chambers, Four Coils, One Mouthpiece
What separates the four flavours is not a valve and not a button. Each chamber is filled and sealed on its own line, so there is no shared reservoir and no mixing between them; the mouthpiece simply redirects the draw to a different chamber. Two consequences follow directly, and both matter more than any figure on the box.
One chamber is being used at a time
Every listed figure for this device is a total across four chambers. Thirty thousand draws per chamber, add the four together and you get the headline number. In practice you use one chamber until it runs dry, then rotate. If you treat the total as a single tank’s worth, you will expect four times more from one flavour than one chamber can give.
The coils are separate and stay separate
Our own specification row states Four Mesh Coils at 1.0 ohm, which is four coils at one per chamber. Some listings describe the same device as a dual-mesh model, so treat the coil count as a published specification rather than something I have measured. What I can report from use is the behaviour: a freshly loaded chamber needs a few small draws before the taste settles, and after that it stays consistent until the chamber is close to empty.
How Long 64 ml Really Lasts
120,000 is the manufacturer’s claim, and it deserves a closer look rather than a straight repetition. Divide the headline figure by the total liquid volume and you get 1,875 draws from every millilitre. Nothing I could find supports that: published consumption guidance and bench measurements put ordinary use somewhere between about 35 and 300 draws per millilitre, depending on how long each draw is and how open the airflow is. The honest conclusion is that the headline is a rating, not a draw-by-draw promise.
A defensible estimate starts from the 64 ml instead. The 1.0 ohm coil points at a moderate, steady draw rather than a high-output cloud setup, so I have planned around the lower-middle of the published ranges. The table converts the arithmetic into the two numbers a buyer actually cares about: total draws and how long the device lasts at a given daily rate.
| How it is used | Planning figure for 64 ml | What that means day to day |
|---|---|---|
| A short, steady draw, as a 1.0 ohm coil is normally used | About 9,600 to 19,200 draws | At 1 ml a day, roughly 64 days; at 2 ml a day, roughly 32 to 64 days |
| Open, high-output draw | About 1,920 to 9,600 draws | At 5 ml a day, roughly two weeks; at 10 to 20 ml a day, a few days to a fortnight |
| Manufacturer’s claim | 120,000 draws | Equal to 1,875 draws per millilitre, which no published consumption figure supports |
Read the first two rows as a planning band and the third as the claim. The band is the one to buy from: it tells you that a moderate user gets about a month out of one device, and a heavy user gets one to two weeks. The 650 mAh cell is rechargeable, so the liquid is what runs out first, not the battery. The two ratings do not agree – and I would rather write that down than sell you a number I cannot stand behind.
Every Figure We Publish, and What It Changes for You
This is the complete specification as our listing states it. The third column is the part the other pages leave out: what each value means when the device is in your hand.
| Parameter | As our listing states it | What it changes for the user |
|---|---|---|
| Puff count | Up to 120,000 puffs | A manufacturer claim across four chambers, not a per-chamber figure |
| Flavour format | 4-in-1 / Four flavours | Four tastes from one body instead of four devices in a pocket |
| E-liquid capacity | 4 x 16 ml | Each chamber is separate and sealed, so a part-used chamber waits without going stale |
| Total e-liquid capacity | 64 ml | The sum of the four chambers; it is not one 64 ml tank |
| Nicotine options | 2% / 5% | Two strengths are listed, so confirm which one is on the variation you order |
| Battery capacity | 650 mAh | Small enough to keep the body pocketable, large enough that a full charge covers a day of moderate use |
| Coil technology | Four Mesh Coils, 1.0 ohm | One coil per chamber at a moderate resistance; expect a steady, unhurried draw rather than a hot one |
| Charging port | Type-C rechargeable | Any standard Type-C cable works; the port is on the body, not on the mouthpiece |
| Display | LED Display | Battery level and the chamber currently open, read at a glance without guessing |
| Product weight | Approx. 150 g per piece | About a third heavier than a single-chamber disposable of similar length; noticeable in a shirt pocket |
| Box quantity | 10 pieces per box | One box covers ten customers, or one customer across ten sets |
| Carton quantity | 100 pieces per carton | Ten boxes to a carton, which is the unit the packing list is built around |
| Carton size | 545 x 273 x 267 mm | A single-layer carton, stackable two high on a standard pallet footprint without overhang |
| Gross weight | Approx. 15.8 kg per carton | Light enough for one person to move by hand and for parcel handling rather than freight only |
Choosing Among the Ten Flavour Sets
Ten sets, four chambers each, so the listing covers forty distinct tastes. Sorting them for a counter is easier once you notice that they fall into four families, and the table is grouped that way rather than by set number. The names below are the manufacturer’s own English names; our shop database holds this list in its German release, so the wording here is the English release of the same ten products.
| Family | Sets in this family | Chamber by chamber |
|---|---|---|
| Fruit with ice | Sets 1, 2, 3, 6 | Watermelon Ice, Blueberry Ice, Grape Ice and Berry Ice recur and are paired with mint, peach or cherry |
| Fruit only, no ice | Sets 5, 9, 10 | Strawberry, mango, watermelon and kiwi builds, with Cranberry Grape or Triple Melon as the soft finish |
| Sour and fizzy | Sets 4, 7 | Melon Apple and Passion Kiss in one, Energy Drink and Sour Apple Raspberry in the other |
| Sweet and confectionery | Sets 3, 8 | Rainbow Candy and Lemon Sour Orange, or Watermelon Bubble Gum and Red Mojito |
Grouping them this way also settles the stocking question: a counter that carries one set from each family covers almost every request it will get, and the family breakdown above is more useful for that than the set numbering. The single strongest starting point among the ten is discussed in the buyer questions below, where the reasoning can be given in full.
Handling the Device: Loading, Switching and Recharging
The mechanism rewards a little patience. Nothing needs to be pressed or programmed, but the first draw after a change does need treating differently from the hundredth.
The first session
Charge to full before the first use; the LED display on ours settled within about an hour on a standard Type-C charger. Then take two or three short, gentle draws from the chamber you intend to use first. That wets the mesh wick and prevents the dry, papery taste that a coil gives when it is asked for a full draw while still dry. Nothing else is needed before the first session.
Switching to a new flavour set
How to change chamber depends on the batch: some units are turned by lifting and rotating the mouthpiece, others use a selector on the body, and the LED display confirms which chamber has opened. Do not force the mouthpiece if it does not move easily, because the assembly is plastic and the seal is the part that suffers. Once the display confirms the change, take the same two or three short priming draws, then use the device normally.
What the display is good for, and what it leaves out
The LED screen earns its place twice: it reports the battery level, and it confirms which chamber the mouthpiece has opened, which is the only reliable way to know what you are about to draw. What our listing does not state is a liquid gauge, so treat the display as a battery and chamber indicator rather than a fuel gauge. Plan chamber changes by taste and by how much you have used that flavour, not by a number on the screen.
Charging routine that looks after the cell
Top up in short sessions rather than running the cell flat and then leaving it on the charger. Unplug once the display reads full, and do not leave the device plugged in overnight on a high-output adapter. A full charge is quick enough that a twenty-minute top-up before a long evening is usually all it takes.
Looking After a Four-Chamber Device
Four chambers mean four seals, four airways and one rotating joint, so this device has more places to look after than a single-chamber disposable. The table below is the short version of what we tell customers who ask how to keep one working properly. These are handling measures, not a claim about how the device is built.
| Situation | Why it matters on this device | What to do instead |
|---|---|---|
| Kept lying on its side | Liquid can creep into a shared airway and show up as gurgling in the next chamber | Stand it upright in a drawer or on a shelf, mouthpiece up |
| Left in a warm car or in sun | Heat thins the liquid in all four chambers at once, and a warm chamber is the one that leaks first | Store at room temperature; carry it in a bag rather than a glovebox |
| Long, fast chain draws | The wick cannot keep up, and the chamber tastes dry before it is empty | Slower, shorter draws; let the device rest between sessions |
| Trying to speed up a rotation | Force on the joint distorts the seal that keeps the four chambers apart | Rotate only as far as it moves freely, and check the display before drawing |
| Liquid at the charging port | Liquid and a live charging circuit do not belong together | Wipe the port dry, and stop using that unit if liquid keeps appearing there |
None of this is complicated, but most of it is specific to a multi-chamber body. The single habit that prevents the most trouble is the simplest one: keep it upright.
Is This the Right Device for You?
Two honest sides, so you can decide before ordering rather than after.
| Suits you if | Rather not if |
|---|---|
| You want variety without carrying several devices | You already know the single flavour you want and never switch |
| You want to buy once a month rather than once a week | You want the smallest possible device, since 150 g and a four-chamber body is not discreet |
| You run a counter and want one line that covers several flavour requests | You are ordering for a customer who will only ever use one taste |
| You favour a moderate, steady draw | You want to tune airflow, wattage or coil resistance, none of which this device offers |
Buyer Questions We Get Asked Before an Order
What exactly is in the box?
One device, pre-filled, in its retail box. Our listing does not state that a charging cable is included, so I will not claim one is; assume you need your own Type-C cable and confirm with us if that matters before you order. Ten of those boxes make a box quantity of ten pieces, and ten of those make a carton.
How do I actually move between the four flavours?
By rotating the mouthpiece or using the selector, depending on the batch, and the LED display confirms the chamber that has opened. It is a mechanical change on the body, not a setting, and there is nothing to press twice or hold down. I have not found a published statement of the exact mechanism from the manufacturer, so this is what the units in front of me do.
Should I expect 120,000 draws?
Plan on the band from the arithmetic, not the headline. For a short, steady draw that is roughly 9,600 to 19,200 draws across the four chambers; for a much more open, high-output style it is closer to 1,920 to 9,600. Both figures come from the 64 ml of liquid at published consumption rates, and both are far below the manufacturer’s claim.
Which set should a shop try before it commits to a carton?
Watermelon Ice, Blueberry Mint, Fuji Apple Ice and Lime Romance. All four chambers sit in the same cool, clean register and none of them is a dessert profile, so a buyer who dislikes one is still likely to work through the chamber it sits in. On a device whose whole point is that all four chambers get used, that is the safest place to begin, and it is a more useful first order than a set built around confectionery flavours.
How do I know when one chamber is running out?
The taste thins before the chamber is genuinely empty, and the change is gradual rather than sudden. Because each chamber holds 16 ml, you have plenty of warning; rotate to another chamber and come back if you want to finish the first one properly. The display reports battery level rather than a liquid gauge on the units I have handled.
Can I adjust the airflow?
Our specification sheet does not list an airflow control, and the units I have used do not have one, so treat the draw as fixed. If a completely open draw is what you want, this is not the device for that; the 1.0 ohm coil is built for a moderate, steady pull.
Which figures are the manufacturer’s and which are worked out here?
Two different kinds of number appear on this page, and it is worth being able to tell them apart before you plan around either.
| Figure on this page | Where it comes from | How to treat it |
|---|---|---|
| 120,000 draws | Manufacturer claim, published in our listing | A rating to quote, not a quantity to promise |
| 4 x 16 ml, 64 ml, 650 mAh, 1.0 ohm, 2% and 5%, approx. 150 g | Manufacturer figures, published in our listing | Buyable specification; the same sheet applies to every unit |
| 9,600 to 19,200 or 1,920 to 9,600 draws | Worked out here, from 64 ml and published consumption rates | The planning band; it is narrower than the claim on purpose |
| 32 to 64 days for a typical user | Worked out here, from the band above and a daily rate | A range, not a date; a heavy user lands at the short end |
Where the two kinds of number disagree, this page says so rather than smoothing it over, and the specification table above names our listing as the source of every manufacturer figure it prints.
Supply, Packing and Support for Shops
The device is packed ten pieces to a box and one hundred pieces to a carton, in a single-layer carton measuring 545 x 273 x 267 mm at approximately 15.8 kg gross. Because the ten flavour sets are packed separately, a mixed order means mixing at box level; say which sets you want and we will build the carton around them rather than sending a single set. Sizes are confirmed with your order acknowledgement, and our team answers questions about chamber rotation, first-session handling and set selection before you commit to a quantity. If you need to reach a person, the contact details on our shop page put you through to someone who handles this model.
