# Choosing a vape for beginners: read the battery > A vape for beginners judged by its battery: capacity against draw, charge time, pod capacity under the UK rules and the three traps of a first purchase. On a site devoted to cells, the reflex would be to recommend something big. That is exactly the mistake most people make on a first purchase, and it comes from confusing capacity with runtime. A vape for beginners lasts a day when its reserve of energy is proportionate to what it consumes, not when the reserve is large. British shop pages tend to sort starter kits by brand and by looks. Sorting them by how much energy they draw is a far more useful exercise, and it is the one this guide runs through. ## Capacity on its own tells you nothing A cell rated at three thousand milliamp hours on a hungry sub ohm setup empties faster than one rated at four hundred on a low powered closed system. The relationship is mechanical rather than mysterious, and it is the reason a compact kit sometimes sees out a working day while an imposing mod asks for a socket in the middle of the afternoon. For a first purchase, the right unit of measurement is not the milliamp hour at all. It is the number of recharges per week you are willing to put up with. Our guide to [vape battery life](/uk/vape-battery-life/) sets out the arithmetic behind that, but the headline is simple enough: what you draw matters as much as what you store. ## Why a vape for beginners rarely needs a large cell Beginner devices in Britain are overwhelmingly pod kits and mouth-to-lung kits, and those draw modestly by design. A small internal cell is not a compromise on that kind of device, it is a match. The device has been engineered around a coil that does not ask for much, so the battery does not have to be large to keep up. The moment you move to a sub ohm tank and a direct-to-lung draw, the demand rises sharply and the same cell would empty in hours. That is the real dividing line in the British starter kit aisle, and it has almost nothing to do with the price or the size of the box. A vape for beginners that draws lightly and charges quickly beats a large device that draws heavily and needs planning around. ## What the published figures actually look like Numbers help, provided you read them against a use rather than against each other. Manufacturers publish enough to make a sensible comparison. Taking one widely sold British range as an example, blu publishes four hundred milliamp hours for the blu 2.0 with around eight hours of moderate use, and a full charge in thirty-five minutes over USB-C with the cable supplied. The blu Bar Kit is published at five hundred and fifty milliamp hours and the blu Box Kit at five hundred and sixty, both quoted at around an hour to charge, with the cable not included. On the consumable side, a blu 2.0 pod of 1.9 ml is published as up to thirteen hundred puffs, and up to nineteen hundred and fifty in power saving mode. A blu Pod of 2 ml is published as up to a thousand. Those figures vary with how a person actually vapes, which is exactly the point. ![Compact rechargeable e-cigarette](/images/articles/meilleurs-modeles-e-cigarette-debutant-france.webp) *On a compact format, usable runtime comes from the low power draw rather than from the size of the battery. Source: blu* ## What the UK rules put in the box Two of those numbers are not marketing decisions, they are the law of the land, and knowing that saves a lot of confused shopping. Every refillable tank or pod sold in Britain is capped at 2 ml, which is why pod capacities cluster just under that figure rather than spreading out. Nicotine containing e-liquid is capped at 20 mg/ml, and the bottles that carry it are capped at 10 ml. Vaping products are not for sale to under-18s anywhere in the United Kingdom, and that covers the hardware as much as the liquid. A vape for beginners bought in a British shop therefore arrives inside a fairly narrow set of specifications, and comparing kits is easier once you know which numbers were never going to vary. ## The three traps of a first vape for beginners The first is the wattage arms race. A device adjustable to a very high setting adds nothing for someone vaping mouth-to-lung, and it empties its battery faster for no gain in comfort. Buying headroom you will not use is buying a heavier object and a shorter day. The second is the removable cell. It is tempting, because a spare pair sounds like unlimited runtime, but it brings a separate charger, a set of handling rules and a level of attention that a first week does not need. That is not a bad choice, it is a premature one, and our [vape battery safety](/uk/vape-battery-safety/) guide explains what it commits you to. The third is the missing cable. A trivial detail, right up until the first evening, when the device is flat and nothing in the drawer fits the port. Check whether the cable is in the box, because British listings state it and most people never look. ## Why the coil matters as much as the battery At equal capacity, two devices do not consume the same, because they do not heat the same. This is the part of a starter kit that never appears on the front of the packaging. On pod systems the coil is built into the pod and calibrated at the factory, so the draw is fixed by design rather than by a dial. Blu, for instance, uses a ceramic vaporisation chamber it calls PurLava, with a porous H shaped structure and a ceramic wick, presented as giving an even rise in temperature and a consistent result across the pod. For a beginner the benefit is twofold: nothing to set, and a predictable energy consumption from one pod to the next. That predictability is what makes a small cell workable, and it is why a sealed system can outlast a much larger device on the same day. ## Matching the device to your day A short, mobile day suits a flat, light format that slips into a jacket. A long day with a lot of puffs suits a larger pod and a quicker charge, so a ten minute stop at a socket restores most of the afternoon. A mostly sedentary day makes the whole runtime question secondary, and you can choose on how the device feels in the hand instead. Whichever way it goes, keep the charging routine sensible from the first week: charge where you can see it, unplug when it is full, and use the cable and adapter the maker intended, a habit our [vape battery charger](/uk/vape-battery-charger-guide/) guide applies to every format. The larger devices keep all of their appeal, but later, once power is a conscious choice rather than a line on a product page. ## Frequently asked questions ### Is a bigger battery always better for a first device? No. A large reserve on a device that draws heavily can give a shorter day than a small reserve on a device that draws lightly. Judge the pair together rather than the capacity alone, and let the way you intend to vape decide. ### How long should a beginner kit last on one charge? Manufacturers publish figures in the region of a working day for compact pod kits at moderate use, but the real answer depends on how often you puff. Treat the published figure as a starting point and adjust after your first week. ### Why are all the pods the same size? Because British rules cap a refillable tank or pod at 2 ml. That is a legal ceiling rather than a design choice, which is why capacities across the market cluster just below it and why capacity is rarely a useful way to separate two kits. ### Should a beginner start with removable cells? Usually not. A device with an internal battery removes the separate charger, the matched pair rule and the handling routine that removable cells require. Those are worth learning, but they are easier to take on once the vaping itself has become routine. ### Does a fast charging device wear out sooner? Charging behaviour is set by the manufacturer on a sealed device, so there is nothing for the user to configure. Follow the instructions supplied with the kit, avoid charging unattended or overnight, and unplug it once it is full. ## Choosing a vape for beginners on the numbers that matter A vape for beginners is best read as a small energy budget rather than as a specification list. What the device draws, what it stores and how quickly it refills are the three figures that decide whether it sees out your day, and they only make sense together. Start from the way you expect to vape, check the published runtime and charge time against that, confirm the cable is in the box and let the legal ceilings on pod size and nicotine strength tell you which comparisons were never going to matter. Pick a vape for beginners on that basis and the hardware fades into the background, which is exactly where it belongs at the start. Editorial content for adult readers only.
