Cigarette électronique Blu: an honest UK review

The cigarette électronique Blu range keeps coming up whenever a UK vaper asks for something pocketable that needs no settings and no thinking about. Reviews are split, though: some testers praise the draw and the build, others find the closed pod format limiting. This piece sorts the two apart, looks at what the hardware actually does, and sets out where the range fits and where it does not.

We have no commercial relationship with the brand and no affiliate arrangement. Everything below is drawn from published UK reviews, manufacturer specifications and the retail listings that British shops publish for the range.

Cigarette électronique Blu: what the range actually is

Blu sits squarely in the closed pod category. You buy a small battery device, you clip in a prefilled pod, and when the pod is finished you clip in another. There is no wattage to set, no coil to change and no bottle to pour. That is the whole proposition, and it is a deliberate design decision rather than an oversight.

The draw is restricted and mouth to lung, which is the tighter style that suits a small device and a modest battery. Vapour output stays low and quiet, which matters more than people expect on a device meant to live in a coat pocket. Heat-up is quick and there is no fire button on the current devices: they activate on inhale.

What the range does not do is give you any room to tinker. You cannot rebuild anything, you cannot fill your own liquid, and you cannot fit a different tank. A vaper who wants to chase flavour through coil choice and airflow tuning will be bored within a week. That is not a fault, it is simply a different product category.

The pods and the coil technology

Blu markets a proprietary coil technology across its pod range, built around a ceramic wicking structure on the blu 2.0 pods and a mesh coil on the blu Bar pods. The claimed benefit is a steadier feed of liquid to the coil so that the wick does not run dry mid-pod, which is the usual cause of the harsh, scorched taste that ruins a session.

In practice that consistency is the thing UK testers tend to single out. A closed pod lives or dies on whether the last third of the pod tastes like the first third, and reviewers of the range generally report that it holds up better than the format's reputation would suggest. Flavour is on the sweet, manufactured side rather than the nuanced side, which is normal for prefilled pods.

Two habits get noticeably more out of each pod. Let the pod sit in the device for thirty to sixty seconds after clipping it in, so the wick saturates properly before the first draw. And stop using a pod once the vapour thins out and the taste flattens, rather than pushing through the last few dry pulls, which does nothing for value and a lot of harm to the taste.

Living with a cigarette électronique Blu day to day

Setting one up takes about two minutes. Charge the battery fully before the first session, push the pod in until it clicks properly home, and keep the device upright between uses so liquid does not creep into the airway. A pod that is not seated cleanly is the single most common cause of a device that produces nothing at all.

Draw technique matters more here than on a bigger device. Slow, steady pulls suit the tight airflow and the small coil; short, hard, repeated puffs flood the wick and dull the taste. Give the device a few seconds between draws and the flavour stays where it should be.

Battery care is the other habit worth forming early. Lithium cells last longer when they are topped up before they hit zero rather than being run flat every day, so plug in at the twenty to thirty percent mark rather than waiting for the device to die. Charging is over USB-C on the current devices, and none of them take long.

Keep the thing out of extremes. A dashboard in July and a coat pocket in February are both bad for the cell and for the liquid in the pod. A hard case costs very little and prevents the two most common ways these devices fail early, which are a crushed mouthpiece and a knock to the charging port.

Which device suits which routine

The blu 2.0 is the slim, cylindrical one, well under twenty grams, built around a 400 mAh battery and 1.9 ml pods. It is the least noticeable device in the range and the obvious pick if what you want is something that disappears in a pocket for a normal working day and charges back up in well under an hour.

The blu Bar Kit is the chunkier one, with a larger battery than the 2.0 and a squarer body that sits more solidly in the hand. It takes blu Bar pods rather than blu 2.0 pods, and it is generally the pick for someone who has used prefilled pod devices before and simply wants the format done reliably.

The blu Box Kit takes the same blu Bar pods and pushes battery life a little further again in a compact rectangular body. It suits people who cannot reliably reach a charger during the day: long shifts, site work, travel days, back-to-back meetings.

The compatibility point is the one that trips people up, so it is worth being blunt about it. There are two separate pod families and they do not mix. blu 2.0 pods fit the blu 2.0 and nothing else. blu Bar pods fit the blu Bar Kit and the blu Box Kit, interchangeably between those two devices only. Check the packet before you buy a multipack.

What UK rules mean for this range

Anything sold legally in the UK follows the same ceilings, and they shape the product more than most people realise. Nicotine-containing e-liquid is capped at 20 mg/ml, prefilled pods and refillable tanks are capped at 2 ml, and separate bottles of nicotine liquid are capped at 10 ml. Sales are restricted to over-18s.

Those limits are why every closed pod device in Britain has small pods, and why puff-count figures on packaging are estimates rather than promises. How long a pod lasts depends entirely on how often and how hard you draw on it, and any single figure quoted on a box should be read as a rough guide.

Single-use disposable vapes were banned from sale in the UK from June 2025, which pushed the whole market towards rechargeable devices with replaceable pods. That is the category the Blu range already sat in, and it explains why closed pod kits are now the default entry point in most British shops. If you want to see the other end of the spectrum, our guide to the Vaporesso Target 100 covers a fully adjustable kit with a removable cell.

FAQ

How long does a blu 2.0 take to charge? The blu 2.0 charges over USB-C and reaches a full charge in well under an hour. Avoid leaving any small lithium device plugged in overnight as a matter of routine.

How do I know when a Blu pod is finished? Vapour thins out noticeably and the flavour loses definition, and some people pick up a slightly different aftertaste towards the end. That is the point to swap it, not a target to push past.

Are Blu pods interchangeable across the range? No. There are two distinct pod families. blu 2.0 pods fit only the blu 2.0. blu Bar pods fit the blu Bar Kit and the blu Box Kit and swap freely between those two. Always check the compatibility line on the packaging.

How long does one pod last? It depends entirely on how you use it. Light use can stretch a pod across a couple of days, heavy use will get through one in a day. Puff counts printed on packaging are estimates, not guarantees.

Does a Blu device need any special maintenance? No tools are needed. Wipe the pod contacts and the rim of the mouthpiece with a dry cloth every few days. Never run water or cleaning fluid over the electronics or the charging port.

Cigarette électronique Blu: the verdict

Judged against what it sets out to do, the cigarette électronique Blu range delivers. The devices are small, the pods are consistent, the draw is tight and quiet, and nothing about the experience demands any technical knowledge. For a closed pod system in the UK market, that is a fair result.

The limits are equally clear and worth accepting before you buy rather than after. It is a closed system, so you are tied to the brand's pods and flavours, the two pod families do not cross over, and the 2 ml pod ceiling means frequent swaps. None of that is a defect, but it is the deal.

Pick the blu 2.0 for discretion, the blu Bar Kit for a more solid device, and the blu Box Kit for battery life. If you outgrow the closed format, the honest next step is a refillable device, and our city guides for Paris and Lyon cover how to keep one supplied while travelling. Whichever way you go, the cigarette électronique Blu range is a coherent piece of design for adults who want the simplest possible version of the thing.
