HEATX-3 vs Ploom: Capsule Heaters Against Heated Tobacco Sticks

The first thing I noticed switching between the two was the weight in my pocket. The Ploom TECH+ is 37 g. I genuinely forget it is in there. The HEATX-3 is 100 g, and it announces itself every time I reach for my keys. That contrast previews most of the differences between these two devices, because they are not competing on the same axis. Ploom sells you a clean, disposable capsule system that asks almost nothing of you between puffs. HEATX-3 sells you a machine with a heating chamber, four temperature modes, and a display that counts your sticks.

Capsule versus stick: what the consumable decides

This is the fork in the road, and everything else follows from it. A heated tobacco stick is what most of the HNB world runs on. The HEATX-3 takes the standard format, universal heated tobacco sticks: a tobacco stick wrapped in paper with a filter end, pushed into a heating chamber. The chamber heats, the tobacco inside generates vapour, and you draw it through the filter. You finish it, tap it out, bin it, repeat. Ploom does not use sticks. The TECH+ takes a capsule, a small sealed tobacco unit, plus a separate heating tube that locks into the top of the device. Insert the tube, insert the capsule, push down, and the device vaporises the liquid inside the heated tube. What comes out is heated tobacco vapour, drawn through a mouthpiece. That difference shows up within a day. The Ploom system is tidy, the parts are simple to load, and there is essentially no residue. The HEATX-3 means handling actual sticks, and a heated stick leaves a used filter and a little tobacco residue in the chamber that you empty and brush out. Cleaning that chamber is the part I enjoy least.

HEATX-3: two heating zones and a 3200 mAh battery

The HEATX-3 runs a Hybrid Heating System GEN3.0 platform with two heating zones instead of one. There is a heating element at the bottom of the chamber and a second that wraps around the stick. The wrapping zone is the interesting part. Most stick-style heaters push heat upward from a single chamber and rely on convection to spread it sideways. The outer edge of the tobacco column gets less energy than the centre, which is one reason a heated stick can taste fine for the first two thirds and then turn thin and papery near the end. Because the second zone encircles the stick, the whole circumference gets heated, and flavour stayed consistent much closer to the end of a session. The numbers around it are generous. 3200 mAh battery, roughly 30 heating cycles per full charge, and 320 seconds of working time per stick. Charging is USB Type-C at 5V / 2A and takes about 2 hours. The body is 35 × 22 × 98 mm at 100 g net weight, in matte black, purple, green and silver. Temperature is handled with four named modes rather than a slider: SOFT, MILD, NORMAL and BOOST, switched with a double press. The screen shows battery level, puff count and the current mode. It is not a touchscreen, and it switches off when idle. Two details I like more than expected. Inserting a stick starts heating automatically, so there is no button to hunt for in a dark doorway, and a long press stops it at any moment. The second is the missing features: no app, no Bluetooth, no firmware updates.

Ploom TECH+: the capsule machine, kept deliberately simple

The Ploom TECH+ is built around doing less and weighing less. Manufacturer figures put the battery at 480 mAh with a charge time of about 60 minutes, the body at roughly 40 × 78 × 18 mm and 37 g. Heating comes from what Japan Tobacco calls Smart HeatFlow, and the consumable is the capsule-and-tube system above. A session runs for 5 minutes, and the manufacturer rates around 20 capsules per full charge. There is no temperature mode, no screen, no puff counter, so the device sits closer to a lighter than an instrument. That simplicity is the whole pitch, and it works. The 37 g is the real achievement, smaller and lighter than the HEATX-3 in every direction that matters for a pocket. If you own a Ploom with2, the differences are incremental: 610 mAh, about 60 minutes of charging, roughly 42 × 74 × 19 mm and 43 g. Same capsule logic, more capacity.

Where the HEATX-3 wins

Endurance, for a start. 3200 mAh and around 30 sticks per charge against 480 mAh and about 20 capsules means you top up roughly half as often. Add the four temperature modes and the on-screen puff counter, and the HEATX-3 gives you visible control over a session in a way the Ploom does not attempt. Vapour consistency is the other one, and it comes from the wrap-around heating zone. If you care that the last thirty seconds taste like the first thirty, the dual heating does something for you.

Where the Ploom TECH+ wins

Speed and simplicity, mostly. An hour of charging against two hours is a real difference if you top up during the day rather than overnight. 37 g against 100 g is not close. The capsule system is also the cleaner experience by some distance. No stick to tap out, no filter and tobacco residue to brush from a heating chamber. If your current Ploom TECH+ review notes made the system sound effortless, that is because it is. Session continuity is worth one more mention. The 5-minute Ploom session runs on and on in one steady flow, and there is no count to keep an eye on. The HEATX-3's 320 seconds per stick is generous, but you are still inside a defined window. And the honest counterweight: buying into the HEATX-3 means committing to a stick system with the cleanup that implies, plus a heavier device that charges more slowly. A real trade, not a free upgrade.

The bottom line

If you want the smallest, lightest, quickest-charging device with the least fuss, and you are happy with one consumable type and no temperature control, the Ploom TECH+ is the better fit, and the capsule system is pleasant to live with. If you want endurance, adjustable intensity and a device that shows you what it is doing, the HEATX-3 is the better fit, and the 100 g and two-hour charge are prices you pay for the 3200 mAh underneath. They are not the same product at different prices. They are two answers to different questions. In any best HNB 2026 roundup, the field splits neatly. IQOS and Glo are stick systems, like the HEATX-3; Ploom sits in the capsule camp. A Ploom TECH+ review tends to praise the refill logic, while stick devices get judged on battery life and temperature control.

A note on health, law and where these numbers come from

Heated tobacco is not harmless. Avoiding combustion reduces exposure to a number of the toxicants found in cigarette smoke, but it does not remove the risk, and every one of these devices delivers nicotine, which is addictive. Nothing here is medical advice, and nothing here is a recommendation to start using tobacco. If you do not already use tobacco or nicotine, there is no reason to begin. If you do use them, follow the age limits and tax rules where you live, buy only from licensed sellers, and check the local rules on where you can use these devices. On the numbers: HEATX-3 figures come from published manufacturer data, and the Ploom TECH+ and with2 figures are manufacturer public data as well.
