Want a vape that lasts weeks and won’t run out on you? The big-puff kits have moved on fast, and the best 50K puff vapes now go toe-to-toe with anything on the market. I tested the most popular one — the Titan X 50K — for two weeks, and lined it up against the longest-lasting kits UK vapers are buying most. Here’s the honest run-down.
How we tested: We used the Titan X 50K for 14 days across four flavour pods, charged it from empty twice, and compared it with other big-puff kits in the 50K–70K range. Flavour and device rankings come from real UK sales data — what people buy and reorder — not sponsored picks.
Why puff counts got this big
Since the UK banned single-use disposable vapes on 1 June 2025, every big-puff device has to recharge and take new pods. That switch is exactly what unlocked these huge numbers: a rechargeable battery plus refill containers instead of a tiny sealed cell. The result is kits rated for 50,000 puffs and up — legal, reusable, and far cheaper per puff.
1.  Titan X 50K — best all-rounder
*Best for: most people leaving disposables.*
The Titan X 50K is our top pick, and the sales back it up — it’s one of the best-selling big-puff kits in the country right now. It comes with two 2ml prefilled pods and six 5ml refill bottles, which is how it reaches up to 50,000 puffs. A mesh coil keeps the flavour clean, it runs 20mg nic salt, and the airflow works for both tight MTL and airier DTL puffs. There’s a small smart display for battery and puff count too.
Grab the Titan X 50K prefilled kit at VapeOnlineStore for ÂŁ11.99, often on a buy-one-get-one-free deal.
Best Titan X 50K flavours (what UK vapers buy most):
- Blueberry Sour Razz / Triple Berry — the number-one seller. Sweet blue razz with a sour edge.
- Strawberry Kiwi Watermelon / Strawberry Raspberry Cherry — big fruit mix, easy all-day.
- Cola Freeze / Fruit Punch — soft-drink flavours with ice.
- Cool Mint — the pick if you came off menthol.
2. The 70K tier — for the heaviest users
*Best for: people who hate refilling.*
If you want the longest-lasting option full stop, step up to the 70,000-puff class. These hold bigger batteries and larger refills, so you top up less often. The stand-out here is the HQD Glow Air 70K, one of the best-selling big-puff vapes in the UK. Browse the full range of 70000 puff vapes at VapeOnlineStore to compare flavours and prices.
How the Titan X 50K vapes
Two weeks in, the flavour holds up well. The mesh coil gives a warm, full puff, and it stays clear right to the end of each pod. At 20mg the throat hit is smooth but enough to handle cravings. Swapping refills is quick, and the display means no guessing on battery.
Pros
- Up to 50,000 puffs — lasts weeks
- Six refill bottles included — great value
- Smart display for battery and puffs
- Works for MTL and DTL
- Often buy-one-get-one-free
Cons
- Fixed 20mg strength

Is the Titan X 50K worth it?
Yes. For the price, you get weeks of vaping, strong flavour and a display, with almost no fuss. If you want one of the best 50k puff vape options and don’t want to overthink it, start here. If you’re a very heavy user, jump to the 70K tier instead.
Our score: 4.7/5 — huge value, strong flavour, easy to live with.
Best 50K Puff Vapes FAQs
Is the Titan X 50K refillable?
You don’t pour liquid in by hand, but it isn’t single-use either. It comes with refill bottles you use to top up the pods, and you swap the pod when it’s done.
How long does a 50,000 puff vape last?
Up to 50,000 is the test figure, so expect a bit less. For most people that’s several weeks to a couple of months.
What’s the difference between a 50K and a 70K vape?
The 70K holds a bigger battery and more refills, so it lasts longer between top-ups. The 50K is smaller and cheaper.
Which Titan X 50K flavour is best?
Based on sales, Blueberry Sour Razz / Triple Berry and Strawberry Kiwi Watermelon are the safest first buys.
Are 50K and 70K vapes legal in the UK?
Yes, as long as they recharge and take replaceable pods. Single-use disposables are the ones that are banned.
