WAKA Optimus 120K Review: 120,000 Puffs and Dual Airflow

The WAKA Optimus 120K is the largest capacity device in the lineup, and the number in the name is the whole pitch: 120,000 rated puffs for $31.99. That works out to well under a cent per puff, which is a different order of value from the 20,000 and 35,000-puff devices most people buy. The question worth answering is whether the hardware behind that number holds up, and whether a device this large suits how you actually vape.

WAKA Optimus 120K at a Glance

Spec	Detail
Rated puffs	120,000
Price	$31.99
Airflow	Dual, with a mouth-to-lung and a restricted-direct-lung setting
Flavour options	10 in the current lineup
Nicotine	Up to 20 mg/mL, the federal Canadian cap (2%)

Put against the rest of the shelf, the price is unremarkable. It sits in the same band as the CoolMax UI 35K at $33.99 and the Cloud Rush at $31.99, both of which are rated for a fraction of the puffs. That is the entire case for the device in one sentence, and everything below is about whether the case holds.

What 120,000 Puffs Means in Practice

A 120,000-puff rating is a manufacturer number, measured under specific conditions, and nobody hits it exactly. What matters is the comparison. A 20,000-puff device at $20.99 works out to about $1.05 per thousand rated puffs. A 35,000-puff device at $33.99 is about $0.97 per thousand. The Optimus 120K at $31.99 lands at roughly $0.27 per thousand, around four times cheaper per rated puff than the 20K tier.

In daily terms, someone taking 200 puffs a day would be looking at a device rated to last most of a year, so the realistic reasons to buy are that you have settled on a flavour, you do not want to reorder often, and you are comfortable with a larger unit in your pocket. If you rotate flavours weekly, a 120,000-puff device is the wrong shape of purchase regardless of what it costs per puff, because you will be carrying one flavour for months.

Dual Airflow: MTL and RDL on One Device

The dual airflow is the feature that separates this from a straight capacity play. Mouth-to-lung means a tight draw, the way a cigarette is pulled: vapour collects in the mouth first and then goes down. Restricted-direct-lung means a looser draw inhaled straight to the lungs, which produces more vapour and a softer throat hit at the same nicotine strength.

Most disposables pick one and commit. Having both on a single device changes how a flavour reads, not just how much vapour you get. A tight draw concentrates a flavour and makes a light profile feel stronger; a loose draw spreads it and softens the edges. That is useful if you buy a flavour that turns out to be too subtle, which is a common complaint with fruit and tea profiles. It is also the reason a device like this suits someone who has not settled on a draw style yet.

The trade-off is that switchable airflow is one more thing to get wrong. Most vapers find they set it once in the first week and never touch it again, so do not buy this expecting to change it daily.

Flavour Range

The WAKA Optimus 120K lineup runs to ten flavours, which is a moderate range rather than a huge one. That is the practical constraint of a 120,000-puff device: a large-capacity unit in a flavour you only tolerate is a worse purchase than three small devices in flavours you like. Before committing, it is worth knowing which of the ten you would still be happy with in month three.

Two guidelines hold up across the range. Mint, menthol and ice profiles are the safest long-haul choice, because cooling does not wear out your palate the way sweet fruit does. Single-note fruits are next. Cream, custard and dessert profiles are the riskiest in a large device, since they are the flavours people most often tire of, and a soft dessert flavour also reads worse on a wide-open airflow setting. If your usual pick is a dessert, buy it in a smaller format and keep the 120K for something you know you can live with.

Living With a 120K Device

A device rated for this many puffs is not a throwaway, and treating it like one is the main way people waste the capacity. Three habits matter. Keep it out of heat, because a device left in a hot car loses flavour long before it runs out. Do not chain-hit it until the flavour goes dry, because a dry hit on a large device is the one failure that ends its life early. And keep it upright when it is not in use, which is the simplest way to avoid a device that starts gurgling or spitting.

The other thing to expect is that the rating and your usage will not match. Someone who takes long, slow draws will get through a device faster than the number suggests, and someone who takes short hits will get longer. The rating is best used to compare this device against a 20K or a 35K, not to predict a date on the calendar.

How It Compares

Device	Rated puffs	Price	Cost per 1,000 puffs
Infinity Lean 20K	20,000	$20.99	About $1.05
RELX Creator 35K	35,000	$21.99	About $0.63
CoolMax UI 35K	35,000	$33.99	About $0.97
WAKA Optimus 120K	120,000	$31.99	About $0.27

The Infinity Lean 20K is the interesting comparison, because at $20.99 it is the cheaper device up front and the more expensive one per puff. If you want a thin device you can lose without caring, that trade makes sense. If you know your flavour, the Optimus wins on cost by a wide margin.

The 35K tier is the middle ground, and the RELX Creator 35K at $21.99 is the value outlier there, working out cheaper per puff than most of the 20K devices. The whole 100,000-plus puff vape collection is worth a look if capacity is what you are optimising for, since the Optimus is not the only large-format option.

Who Should Buy It

Buy it if you have a flavour you already trust, you are tired of reordering, and you want the lowest cost per puff on the shelf. The dual airflow is a real bonus for anyone still working out whether they prefer a tight or a loose draw, and it makes a subtle flavour more usable than it would be on a fixed-airflow device.

Skip it if you switch flavours often, if you want something pocketable, or if you have never used the flavour before. In those cases a 20,000-puff device at $20.99 or a 5,000-puff unit is a better first step, and the money you save buys a second flavour to compare against. The Optimus is a device for someone who already knows what they want, bought in bulk because they know it.

Frequently Asked Questions

How much does the WAKA Optimus 120K cost in Canada?

$31.99 in the current lineup. At 120,000 rated puffs that is roughly $0.27 per thousand puffs, which is about four times cheaper per puff than the 20,000-puff tier at $20.99.

Does the WAKA Optimus 120K have adjustable airflow?

Yes. It has two settings, one for a tight mouth-to-lung draw and one for a looser restricted-direct-lung draw. The tight setting concentrates flavour, the loose setting produces more vapour and a softer hit.

How long will 120,000 puffs last?

Longer than most people expect. At around 200 puffs a day, the rating suggests most of a year, though real usage depends on draw length and how often you use it. Treat the number as a way to compare devices rather than a fixed lifespan.

Is 120,000 puffs too much for a first device?

Usually yes. If you have not used the flavour before, buy a smaller device first and confirm you like it. A large-capacity unit only saves money when you actually finish it, and an unfinished one is the most expensive way to buy.
