HEATX-3 vs Pulze: 3200mAh Dual Heating Against the 57g Pulze 3.0

I went through a workweek with the HEATX-3 in my coat pocket and the Pulze 3.0 in the other pocket, and the two devices made their case in completely different ways. The HEATX-3 is heavy, long and stubborn about battery life. The Pulze is light, thin and quick off the charger. The honest answer depends on how you carry a device around. Every brand claims a small HNB device, then hands you something that weighs a phone and runs for a weekend. The comparison below is based on published specifications and a week of commuting.

Two devices that answer the portability question differently

The Pulze 3.0 is a stick about the length of a lighter, and at roughly 57 g it disappears into a pocket in a way the HEATX-3 simply does not. The HEATX-3 is 35 × 22 × 98 mm and 100 g, and 100 g is a number you feel. When I reached into my coat pocket on the train, it was always the HEATX-3 I found first. The HEATX-3 buys its endurance with size, running two heating zones and a 3200mAh cell. The Pulze 3.0 buys its lightness with a smaller 1850mAh cell and a single ceramic heating rod running inside-out. Imperial Brands also sells the previous Pulze 2.0, at about 52 g and roughly 124 × 23 × 16 mm, so the 3.0 is slightly the bigger of the two.

The numbers side by side

Here is what the manufacturers publish for each device:

And the usage side:

Battery life: where the HEATX-3 pulls ahead

The gap in cell size is the single biggest technical difference here. 3200 mAh against 1850 mAh is close to a 1.7x difference, and it shows up in the cycle count: about 30 heating cycles per charge for the HEATX-3 versus 25+ for the Pulze 3.0. That is not a landslide. It is 5 or so extra sticks, which over a week of 8 to 12 sticks a day is the difference between charging on Sunday night and Wednesday afternoon. On a multi-day trip with no guaranteed socket, it matters more. Charging time pulls the other way, and this is the HEATX-3's clearest trade-off. Two hours from empty is long next to the Pulze 3.0's roughly 85 minutes. If you charge overnight the difference never touches you. If you top up while the kettle boils, 85 minutes feels better than 120. The Pulze 3.0 uses 5-segment linear LED indicators for battery level. The HEATX-3 has a small non-touchscreen display showing battery level, puff count and current temperature mode, and it comes in four matte colours: black, purple, green and silver. Insert a stick and it starts heating automatically, and a long press stops it whenever you want.

Heating and control: four modes and dual zones against two

The HEATX-3 uses the GEN3.0 Hybrid Heating System, with two heating areas: a base zone under the stick and a wrap-around zone that heats the full circumference. The stated effect is more even heat across the tobacco, so the flavour does not thin out as the stick burns down. The Pulze 3.0 uses a ceramic heating rod built inside-out, and preheats in about 20 seconds. I have no instrument bench here, so I am not going to tell you which one extracts more. From using both, the Pulze reaches usable temperature fast enough that a 20 second wait feels like nothing, while the HEATX-3 takes a moment longer and then holds its temperatures steadily. Control is the more visible gap. The HEATX-3 offers 4 named modes, SOFT, MILD, NORMAL and BOOST, cycled with a double press, and the display always tells you which one is active. The Pulze 3.0 offers 2, Intense and Mild, with no published temperature slider. Two modes is fewer, though the choice is obvious enough that I stopped thinking about it in a day. The 5-minute session on the Pulze 3.0 has no fixed puff limit, which I prefer to a hard stop. The HEATX-3 gives you 320 seconds of working time per stick, roughly 5 minutes and 20 seconds, with a long press to stop heating early whenever you want. Anyone telling you the HEATX-3 cuts you short has got it backwards. The real difference is that the Pulze has no cap on puffs.

Sticks and ecosystem: the thing people miss until it bites

The HEATX-3 uses standard heated tobacco sticks. It is not locked to one brand's consumables, which for a lot of users is the point: you can buy whatever is available locally. The Pulze 3.0 works with iD and iSENZIA sticks from Imperial Brands, including tea-based tobacco-free nicotine sticks. If you commit to that ecosystem you get consistency a multi-brand device cannot offer. But it is a closed system, so your supply depends on Imperial's own retail and online channels. For a Pulze review that closed system is the headline feature; for anyone comparing the two, it is the decision point.

Honest weaknesses on both sides

The HEATX-3 is heavier and shorter than the Pulze 3.0. 100 g against about 57 g is a big gap, and 98 mm against about 126 mm means the HEATX-3 sits lower in a trouser pocket while the Pulze stands taller. In a slim front pocket it is bulkier and less comfortable for a full day. It also has no app, no Bluetooth and no firmware updates, so if you like seeing your usage on a phone, it will not do that. On the Pulze side, the honest gaps are the 1850mAh cell, the roughly 85-minute charging cycle, two temperature modes only, and the closed stick ecosystem. The Pulze 2.0 at about 52 g and roughly 124 × 23 × 16 mm is the lightest of the three if weight matters.

Which one to buy for travel and commuting

If your day involves trains, planes, long walks and pockets that are already full, the Pulze 3.0 is easier to live with. 57 g is light enough that you forget it is there, it is ready in about 20 seconds, and 85 minutes of charging fits into a coffee break. If your priority is battery life and flavour consistency, the HEATX-3 takes it. 3200mAh and about 30 cycles per charge means fewer charging rituals, and 4 temperature modes give you real control instead of a binary choice.

The final call

The HEATX-3 vs Pulze question comes down to which compromise you would rather live with. The HEATX-3 asks you to accept 100 g and 98 mm in exchange for a 3200mAh cell, about 30 cycles per charge and dual heating that keeps flavour steady to the end of the stick. The Pulze 3.0 asks you to accept a smaller battery, 25+ cycles, two modes and a closed ecosystem in exchange for a 57 g body that fits anywhere. For a traveller or commuter, I keep coming back to the Pulze 3.0 on weight alone. For someone who charges nightly and dislikes switching brands of stick, the HEATX-3 is the better long-term fit.

Health, law and where to buy

None of this is medical advice. Heated tobacco is not harmless. It avoids combustion and therefore lowers exposure to a number of the toxicants found in cigarette smoke, but it still delivers nicotine, which is addictive, and no heated tobacco product is risk-free. If you do not already use tobacco or nicotine, there is no reason to start. Follow the age restrictions and tax rules where you live, and buy only from licensed sellers, since counterfeit sticks remain a real problem in this category.
