ILUMA i vs ILUMA i ONE vs ILUMA i PRIME: Which One to Buy

Which ILUMA to buy: the short answer

Choosing between ILUMA i, ILUMA i ONE and ILUMA i PRIME? Buy ILUMA i ONE if you want the simplest and cheapest device: one piece, up to 20 sticks in a row, from 4,200 THB (about $122). Buy ILUMA i if you want a touch screen, pause mode and a battery-saving mode, from 5,100 THB (about $149). Buy ILUMA i PRIME only if the look matters to you: it works exactly like ILUMA i in a premium aluminum case, from 5,600 THB (about $163).

The heating is identical on all three: the same induction system, the same TEREA sticks, the same session length. What changes is how you charge, how many sticks you get back to back, and what you’d do with the device when your trip ends.

ILUMA i comparison: the spec table

All figures come from IQOS’s own spec pages. Prices are our “from” prices in Thailand.

What doesn’t change: a session lasts up to 6 minutes or 14 puffs, heating takes about 20 seconds, and there’s no blade to clean.

ILUMA i vs ILUMA i ONE: two pieces or one

ILUMA i splits into a slim holder and a pocket charger. You smoke from the holder, and after up to 3 sticks it goes back into the charger to top up. ILUMA i ONE has the battery built in, so you just keep going, up to 20 sticks without stopping.

Over a full day the count is the same, about 20 sticks, but the rhythm differs. At a bar or on a long night out, the ONE never makes you wait. With ILUMA i, a chain of more than 3 sticks means a short break while the holder recharges.

In return, ILUMA i gives you three things the ONE lacks:

• Touch screen. You see when the stick is ready and how much charge the holder has left.
• Pause mode. Your Grab shows up halfway through a stick? Swipe down, and the session waits up to 8 minutes. You get one pause per stick, only in its first minutes, and FlexPuff is off for that stick.
• FlexBattery. Switch to Eco mode in the IQOS app and the holder does 1 stick per charge. In return, IQOS says the holder battery can last up to a year longer.

The ONE is also lighter, at about 74 g against 143 g, and it charges faster. For a pocket or a small beach bag, that counts.

ILUMA i vs PRIME: is the PRIME worth it?

Short version of our ILUMA i PRIME review: it’s the nicest-looking ILUMA and it smokes exactly like the cheaper ILUMA i. Both use the same holder, the same screen and the same features. Only the pocket charger is different.

On the PRIME, the charger is aluminum and closes with a wrap-style cover, not a door. It feels solid in the hand, and it’s heavier: 134 g against 112 g for the ILUMA i charger. Battery, charge time and sticks per charge are identical.

So the extra 500 THB (about $15) buys finish, not performance. If you’ll carry it every day for years and like nice objects, it’s a fair price. If you just want the screen and pause mode, ILUMA i does the same job.

Which ILUMA for a two-week trip, and which for living here

On holiday for a week or two: ILUMA i ONE. It’s the cheapest, it’s one device with one USB-C cable, and there’s no second piece to leave on a sunbed. Charge it overnight in the hotel and you start the day with up to 20 sticks. Before you pack it for the flight home, check your own country’s rules. Australia, Singapore and India ban or restrict heated tobacco devices and sticks, so for many visitors it’s a device for the trip, not one to take home. Our guide to bringing cigarettes, TEREA and vapes home from Thailand has the limits by country.

Living in Thailand: ILUMA i. If you smoke every day for months, the screen and pause mode earn their place, and Eco mode helps the holder battery last longer.

Want the best-looking one, or buying a gift: ILUMA i PRIME. Same daily experience as ILUMA i, with a premium feel.

A note for both groups: all three are rated for 0–40°C. Thai shade is usually fine. Midday sun on the sand, a closed car or a scooter’s seat box can get hotter than that. Our guide to using IQOS ILUMA i in Thailand covers charging, plugs and the heat in more detail.

All three take TEREA only

Every ILUMA i model heats by induction. The heating element sits inside the stick, so they need ILUMA sticks, which in Thailand means TEREA. TEREA from Japan, Indonesia and Malaysia all fit all three devices. There’s no separate TEREA for the ONE or the PRIME.

HEETS won’t work in any of them: they have no metal element for the coil to heat. HEETS are discontinued and no longer available anyway. If you’re switching, our HEETS page matches your old flavor with the closest TEREA. And don’t put TEREA into an old IQOS with a blade: IQOS warns against it.

Not sure which sticks to pick? Our TEREA flavors guide rates each one for strength and menthol.

Prices in Thailand and how to order

Device prices are in the table above. TEREA comes by the carton of 10 packs, from 2,400 THB (about $70) each when you order 2 or more. Standard delivery anywhere in Thailand is free, next day in Bangkok. Models and details are on our ILUMA i page, and stick prices on the TEREA page.

Tell the manager on WhatsApp or Telegram which model you want. They’ll confirm what’s in stock, the final price and your address before you pay.

Heated tobacco is formally banned in Thailand, though enforcement is softer in practice. The one real risk is airport customs, which is why ordering after you land is easier than flying in with a device.
