Bang Legend 5-in-1 120000 Puffs

Fifteen months with five-tank devices, and what this page settles

I have kept a running tally of every multi-tank device that has come through the shop since the middle of 2025, and the Bang Legend 5-in-1 120000 Puffs is the fifth one I have carried long enough to know properly. Fifteen months of selling, refilling, charging and arguing with suppliers about them has taught me that the headline on the box is the least useful number on it, and that the number a buyer actually needs is the one nobody prints: how much liquid sits in one tank.

So this page is built around that. It states what our own listing for this device says, shows it beside what several other listings for the same model claim, works the liquid out per tank and in total, and gives you a draw estimate derived from the 40 ml rather than from the 120,000 figure. It also names the two things about this product I could not confirm, instead of quietly filling the space with a number from somewhere else. If you want the short version, read the specification section; if you want to know whether it will last you a month, read the section on the arithmetic near the end.

What this listing states, and what other listings claim

The Bang Legend 120K is sold under one model name and described with at least three different specification sets online. The table below separates what our own listing for this device states from what a set of other shops currently claim for the same model, so you can see the disagreement for yourself before you decide which page to trust.

Two of those rows are gaps on our side, not claims, and I am leaving them as gaps. A specification I cannot read off our own listing is not something I will copy from a competitor’s page, because the two of us are describing different production batches until somebody proves otherwise.

The five-tank frame: 8 ml per tank, one coil per tank

Five tanks and five coils is the whole design, so it makes sense to look at one tank at a time rather than at the device as a single 40 ml block. Each tank holds 8 ml and is served by its own 1.0 ohm mesh coil, and turning the dial at the base moves you from one to the next.

Why five small chambers beat one big one

That last row is the honest reason the five-tank format exists. You are not buying 40 ml of one flavour; you are buying five 8 ml portions that happen not to share a wick, and the moment you accept that, the draw estimate further down this page stops looking pessimistic and starts looking like ordinary arithmetic.

The full specification, and what each figure changes for you

Every figure below is the one our listing for this device carries. The third column is the part most specification sheets leave out, which is what the number does to your day.

One number is deliberately absent from that table: the strength of the liquid. Our own specification sheet does not state it and, as noted above, the strength field on our own product listing is configured but carries no value, so there is nothing for me to print. I am not going to borrow a figure from a shop that is describing a different batch.

The twelve labelled sets, and the one that is missing

Our listing carries twelve numbered sets of five flavours. Be aware of two things about that list before you order. Its ninth entry appears on the specification sheet but is not among the twelve options our listing lets you select, and its seventh entry appears twice in that option list. If the set you want is set nine, ask us first rather than assuming.

The two entries that matter most in that list

The names in that table are ours. Four of the twelve sets are spelled differently on other listings for this model, including one that calls a flavour bear fudge where our sheet says gummy bear, and one that names a fruit our sheet does not. Those are listing differences on the same model number, and I have no way to tell from here which spelling matches a given production batch.

Using it: the dial, the display, the first fill

Selecting a tank without guessing

Turn the dial on the base slowly until it seats. Our listing describes a click as it indexes into position, and that click is the whole instruction: if you stop between two detents the airflow is shared and the taste you get is a blend of the two tanks on either side. Take the first draw after a switch as a throwaway. It clears the small amount of vapour still sitting in the shared mouthpiece, and the tank you selected reads properly from the second draw onwards.

What the display is actually telling you

The screen reports battery level and the liquid level of the tank you are on. Treat the liquid figure as the more useful of the two, because it is the one that stops a dry draw: switch away from a tank that is nearly empty rather than trying to finish it, and the wick in that tank stays intact for whenever you come back to it. The battery figure matters mainly because output sags near the end of a charge, so a tank that tastes thin on a low battery usually tastes right again after ten minutes on a cable.

Charging it properly the first time

There is nothing to prime and nothing to fill. Stand the device upright for five minutes after unboxing so any liquid that moved in transit settles back over the wicks, then charge it to full before the first session. Our own notes from testing put a full charge at about fifteen to thirty minutes on a Type-C cable, which is quick enough that the habit worth forming is a short top-up rather than an overnight session.

Looking after it: charges, coils, and what a fault costs

An 850 mAh cell behind 40 ml of liquid is not a one-charge device, and this is the part of owning a five-tank model that catches people out. The cell is a compact 18350 format, generally rated between 700 and 1,200 mAh depending on the batch, and 850 mAh works out at roughly 3.15 watt hours. That is a few hours of ordinary intermittent use per charge, not a week of it, so plan on recharging this device repeatedly across the life of one fill.

The one fault that matters on this design

Because all five tanks share a single selector and a single frame, a selector that stops indexing takes the other four tanks with it. That does not make the device fragile, but it does mean the dial is the part to handle gently and the part to mention first if you ever need to raise a fault with us. The 18350 format is also standardised, which is the reason a device this size can be specified with a cell in the first place.

That last row is the concession I would want a shop to make to me. Five coils spread the load, but they do not make each coil immortal, and a tank is about the amount of liquid one mesh coil handles before the taste goes flat. Anyone promising you otherwise is selling you the box, not the device.

Which of the twelve sets suits which taste

Every listing for this device prints the twelve combinations, so printing them again would tell you nothing. What is missing from all of them is a recommendation, so here is mine, grouped by what you actually reach for.

• If you want one taste all day: set 7, the watermelon ice and mixed berry line. It is the only set of the twelve with no candy tank and no cola tank in it, so nothing in it turns heavy by the fourth day.
• If you want the five tanks to feel genuinely different: set 6. Bubble gum next to sour lime next to melon is the widest spread on the sheet, which is the point of paying for five tanks rather than one.
• If you like cold: set 2. It is the only set where every one of the five carries an ice or a chill, so you are not switching between cold and warm tanks.
• If you want the safest gift or first order: set 1. Energy drink and blueberry cherry in the same box covers the two profiles most people already know they like.
• If you want something for evenings rather than all day: set 11, the creamy and floral one. It is the softest of the twelve and the one I would not choose as a daily.

My single recommendation, if you are ordering one: set 5. It is the most balanced of the twelve, with one cold tank to start and four tropical tanks that do not fight each other, which means the device stays interesting across a full 40 ml instead of collapsing into one taste after the second tank. If you already know you want cold fruit, take set 2 instead and ignore me.

How many draws the 40 ml really holds

Here is the division that no listing for this device seems willing to do. Take the liquid, not the rating. A short, light draw on a device like this uses roughly 0.003 to 0.005 ml of liquid, which is the same thing as saying one millilitre covers somewhere between 200 and 300 draws. A long, open draw burns through far more: about 65 to 150 draws to the millilitre. Applied to one 8 ml tank and then to all five, that gives the bands below.

• Short, light draws: roughly 1,600 to 2,400 draws from a single 8 ml tank, and about 8,000 to 12,000 draws across all five.
• Long, open draws: roughly 520 to 1,200 draws from a single tank, and about 2,600 to 6,000 draws across all five.

Where the 120,000 figure comes from

For comparison, the 120,000 figure works out at 3,000 draws from every millilitre of liquid in the device. That is not a lie about the hardware; it is a machine measurement taken under a short, fixed, standardised puff, and it is the same kind of number that appears on every disposable in this class. It is simply not what a person does with their mouth. A device from the same run that was measured on a bench returned 1,200 draws against 2,100 claimed, and a separate published estimate puts low-power consumption at 0.003 to 0.004 ml per draw, which lands in the same place as the band above.

What that means in practice, and this is the part I would want to know before ordering: at a moderate fifteen draws an hour, one tank is a fortnight and the full 40 ml is a couple of months of evenings. At seventy draws an hour, one tank is about a day and a half and the whole device is roughly a week. Your number is somewhere between those two, and it is set by your draw, not by the box.

Questions that come up before ordering

What exactly is in the box when it arrives?

Our specification sheet for this device does not state the box contents, so I cannot give you an itemised list, and I will not copy one from another shop’s page. Assume the device itself and confirm anything else with us before you order, particularly if you are buying for a shop and need to know the pack count.

The strength option on the product page is empty. Why?

Because the field is configured on our listing but no value was ever attached to it. Our specification sheet does not state the strength of the liquid either, so there is nothing to print and nothing for you to pick from the dropdown until the supplier confirms the figure. That is a gap on our side and I am publishing it as a gap rather than filling it with a competitor’s number.

Set nine is on the sheet but not in the options. Can I order it?

Ask us first. Our specification sheet lists twelve sets, our option list carries twelve selections with the seventh repeated, and set nine is the one that does not appear. It may exist and simply never have been attached to the listing, or the sheet may be a step ahead of the batch we hold. One message settles it.

One tank has gone quiet or tastes burnt. Is the whole device finished?

No, and this is the practical advantage of five separate chambers. Switch to a different tank, and if the other four behave normally you have lost one coil rather than the device, with 32 ml of the 40 ml still usable. If the other tanks also go quiet, the selector or the cell is the more likely cause, and that is the case to bring to us with the order number.

Can I carry this in a pocket, and does it leak when I do?

It is a large frame, so it is a jacket or a bag device rather than a shirt-pocket one, which is the trade you make for five tanks. The chambers are sealed, so the usual cause of a little liquid appearing in the mouthpiece is carrying it lying down with a part-used tank, or leaving it somewhere hot. Standing it upright between sessions is the whole remedy.

Buying for a shop: what the five-tank format does to your margin

If you are stocking this for resale, judge it on the format rather than on the 120,000 on the front of the box, because the format is what sells and what comes back. The commercial case for a five-tank device is straightforward: one SKU covers five taste profiles, so it takes a fifth of the shelf space that five single-flavour devices would need, and a customer who likes one tank has a reason to try the other four before they buy anything else. That is also why it upsells well from a single-flavour device of the same size.

The other side of the same design is where your return rate comes from, and it is worth being blunt about it. Five tanks mean five chambers, five coils and one selector, so there are more seals and more moving parts than a single-flavour device of the same capacity, and the selector is a single point of failure across the whole frame. Dead stock is the other exposure, because a set whose five flavours do not hang together will sit while a better-balanced set moves, which is why I would not fill a shelf with one combination. Customers also need a sentence of explanation about the dial, and a shop that does not give it will see the device come back described as weak or mixed when nothing is wrong with it.

What to settle before you commit to a volume

What I would ask for before committing to a volume: a sample from the batch you are actually buying, a leak and selector check on that sample, and a written answer on two things our own listing could not give me, the liquid strength and the pack contents. Those are the two figures that decide whether a customer comes back, and neither should be quoted to you from a competitor’s page. Bulk supply, private-label terms and OEM or ODM support for your own brand are all available on this model and are quoted per order, with the figure confirmed once your quantity and options are fixed.
