If you're searching for the best e-cigarette to quit smoking, you're probably comparing a lot of similar-sounding devices and wondering what actually separates them. In practice, it usually comes down to a handful of practical factors: how long the battery lasts, how many puffs you get before a refill, how easy the device is to use day to day, and whether the flavours actually feel like a fair swap for a cigarette.
This guide walks through what to look for in an e-cigarette, then compares BrickBar's two rechargeable devices, the Air7000 and the Air12000, so you can see how they differ and decide which one suits your preferences.
A quick note before we start: switching to vaping is a personal choice, and this article doesn't offer medical advice. If you're trying to stop smoking, it's worth speaking to a GP, pharmacist, or a stop-smoking service for guidance suited to your situation; we'll touch on this again later in the article.
What Should You Look for in an E-Cigarette?
Not all e-cigarettes are built the same, and the differences show up quickly once you're using one every day. Here's what tends to matter most:
- Battery life and charging: A device that dies by mid-afternoon is inconvenient at best. Look for a decent battery capacity and fast charging, ideally via USB-C.
- Puff capacity: This gives you a rough idea of how long a device or pod will last before you need to refill or replace it. Higher-capacity devices need less frequent topping up.
- Refill or pod capacity: Some devices use a refillable tank, others a smaller pod system, or a combination of both. Larger tanks mean fewer refills.
- Nicotine strength: Available strengths vary by product and region. UK e-liquids are legally capped, so check the specific strength listed for the device you're considering.
- Flavor range: A wider range of flavours makes it easier to find something you actually enjoy, rather than settling for whatever's available.
- Portability and design: A slim, pocket-friendly device is easier to carry and use discreetly than a bulky one.
- Ease of use: Look for straightforward operation: no complicated settings, simple refilling, and a design that doesn't require much maintenance.
Rechargeable vs Disposable E-Cigarettes
This is one of the more practical decisions when choosing a device, and it's also among the best rechargeable e-cigarette searches people run before buying.
Disposable vapes are used once and thrown away when the battery or e-liquid runs out. They're simple, but the ongoing cost adds up if you're buying a new one every few days, and they generate more waste.
Rechargeable vapes, like BrickBar's Air7000 and Air12000, use a USB-C rechargeable battery paired with a refillable tank. You top up the e-liquid rather than replacing the whole device, which tends to work out cheaper over time and produces less waste per puff. The trade-off is that you'll need to remember to charge the device and keep it topped up with e-liquid, which is a small extra step compared with a disposable.
Neither format is objectively better; it depends on whether you'd rather have zero maintenance (disposable) or lower running costs and less waste (rechargeable).
How to Choose an E-Cigarette Based on Your Preferences
There's no single device that suits everyone, so it's worth thinking through a few questions:
- How often do you want to refill? If you'd rather refill less frequently, a device with a larger tank capacity is worth prioritizing.
- Do you want a compact device or one built for longer use between top-ups? Smaller devices are easier to carry; larger-capacity devices mean less frequent refilling.
- Which flavours do you actually enjoy? Fruit, ice, and menthol profiles all suit different preferences; there's no universally correct choice.
- How important is battery longevity to you? If you use your device heavily throughout the day, check the battery capacity and charging speed before buying.
- With those questions in mind, here's how BrickBar's two devices compare.
BrickBar Air7000
The Air7000 is BrickBar's more compact rechargeable device, built for straightforward daily use:
- Puffs: up to 7,000
- Kit size: 112mm x 46mm x 15.9mm
- Nicotine strength: 20 mg/ml
- Refill container capacity: 6 ml
- Refillable pod capacity: 2 ml
- Battery capacity: 800mAh
- Charging: USB-C
- Flavours include: Blue Razz Lemonade, Watermelon Ice, Strawberry Ice, and Fizzy Pineapple
Its slimmer profile and simpler day-to-day handling make it a reasonable starting point if you want a device that doesn't require much thought, refill it, charge it, and go. Full specs and current flavour availability are on the Air7000 product page.
BrickBar Air12000
The Air12000 is the higher-capacity option in the range, designed for those who'd rather refill less often:
- Puffs: up to 12,000
- Kit size: 122mm x 46mm x 15.9mm
- Nicotine strength: 20 mg/ml
- Refill container capacity: 10 ml
- Refillable pod capacity: 2 ml
- Battery capacity: 800mAh
- Charging: USB-C
- Flavors include: Menthol Cherry Ice, Mango Peach, and Pink Lemonade
The larger 10 ml tank means fewer refills across a similar period of use compared with the Air7000, at the cost of a slightly larger footprint. See the full range on the Air12000 product page.
Air7000 vs Air12000
Factor Air 7000 and Air 12000 Puff Capacity Up to 7,000, up to 12,000 Refill container capacity: 6 ml, 10 ml Refillable pod capacity: 2 ml 2 ml Kit size 112 x 46 x 15.9 mm 122 x 46 x 15.9 mm Battery 800mAh, USB-C 800mAh, USB-C Nicotine strength 20 mg/ml 20 mg/ml Best suited to those who want a slightly more compact device Those who'd rather refill less often
Both devices share the same battery capacity, nicotine strength, and mesh coil build via BrickBar's Technology, so the main decision point is really tank size versus device footprint. Across both devices, BrickBar offers 10 flavours in total, including Lemon & Lime and Blueberry Sour Raspberry. Alongside those listed above, you can see the complete range in the shop.
Important Considerations About Vaping and Smoking
It's worth being upfront about a few things:
- Vaping is not risk-free. E-cigarettes are generally considered by public health bodies to expose users to fewer harmful chemicals than cigarette smoke, but fewer isn't the same as none, and long-term evidence is still developing. If you have questions about the health implications of vaping, that's worth raising with a healthcare professional.
- No e-cigarette is guaranteed to help you quit. Vaping works for some people as part of switching away from cigarettes, but individual results vary considerably, and a device on its own is not a treatment.
- Nicotine is still addictive. Vaping e-liquid containing nicotine will maintain a nicotine dependency, even if it changes how that nicotine is delivered.
- If stopping smoking is your goal, established stop-smoking support, such as NHS Stop Smoking Services, a GP, or a pharmacist, can offer guidance tailored to you, including options beyond vaping.
- Age restrictions apply. BrickBar products are intended for existing adult smokers and vapers aged 18+ only, in line with UK law. You can review verification requirements on our Verification page.
We're not able to make cessation claims about our products, and we'd rather be straightforward with you than overstate what any device can do.
Conclusion
Choosing between e-cigarettes usually comes down to a short list of practical factors: how long the battery lasts, how much liquid the tank holds, how often you're willing to refill, and which flavours you'll actually enjoy using. BrickBar's Air7000 and Air12000 are both rechargeable, refillable devices built around the same core technology, with the main difference being tank size and puff capacity, the Air7000 for a slightly more compact everyday device, and the Air12000 for those who'd rather refill less often.

Frequently Asked Questions
What is the best e-cigarette to quit smoking?
There's no single device that works best for everyone. The right choice depends on your priorities; puff capacity, refill frequency, device size, nicotine strength, and flavour preference all play a part. Comparing devices on those factors, rather than looking for a single best product, tends to be more useful.
How do I choose the best e-cigarette to quit smoking?
Start with the practical factors: battery life, tank or pod capacity, nicotine strength, and flavours you'd actually enjoy. From there, decide whether a more compact device (like the Air7000) or a higher-capacity one (like the Air12000) fits how you'll use it day to day.
What should I look for in an electronic cigarette?
Reliable battery life, a refill or pod capacity that matches how often you're willing to top up, straightforward charging (USB-C is now standard), and a flavour range that suits your taste.
Are rechargeable e-cigarettes a good option?
Rechargeable, refillable devices generally cost less to run over time than disposables and produce less waste per puff, since you're topping up e-liquid rather than discarding the whole unit. The trade-off is a small amount of extra maintenance, charging, and refilling, compared with a disposable.
What is the difference between an e-cigarette and a vape?
In everyday use, the terms are interchangeable; both refer to devices that heat e-liquid to produce a vapor, rather than burning tobacco.
What is the difference between BrickBar Air7000 and Air12000?
The main differences are puff capacity (7,000 vs 12,000) and refill container size (6 ml vs 10 ml), with the Air12000 slightly larger in kit size as a result. Battery capacity, charging, nicotine strength, and pod design are the same across both.
