Gcore
High capacity disposable vapes running from the compact G32 up to the 40,000 puff GT40000, all rechargeable by necessity and all at or under the Canadian 20 mg/mL nicotine cap.
Gcore competes almost entirely on capacity. Where most disposable brands top out around five or seven thousand puffs, the Gcore range runs to twenty and forty thousand, and that single decision shapes everything else about the products: they are physically larger, they carry rechargeable batteries as a necessity rather than a feature, and most of them include a screen.
We stock five: the G32 at $22.99, the Aura at $22.99, the Boost at $24.99, the GC20000 at $24.99 and the GT40000 at $29.99. All are disposables, which makes this the most focused brand range in the shop and the easiest to choose within.

What high capacity actually buys you
A device advertised at forty thousand puffs is not going to deliver forty thousand human puffs, and nobody in the industry seriously claims otherwise. Those figures come from a testing machine drawing a consistent two to three second puff under laboratory conditions. A real person takes longer, deeper and more variable draws, so the honest expectation is roughly half.
What the number does tell you reliably is relative capacity. A GT40000 genuinely holds more liquid than a GC20000, which genuinely holds more than a G32. Ranking within a brand is the useful information, not the absolute figure.
The practical benefit is fewer purchases and less packaging per millilitre. The practical cost is a larger object in your pocket and a longer period during which the flavour has to stay good. Our disposable vape life calculator estimates duration from your own consumption rather than from a machine.
Why these devices recharge, and what that does not mean
Every high capacity disposable is rechargeable, and this is a necessity rather than a selling point. A battery large enough to vaporise twenty millilitres of liquid in one charge would make the device impractically big, so the manufacturer fits a smaller cell and a USB C port instead.
Recharging buys you the rest of the liquid. It does not extend the life of the coil, and it does not make the device refillable. When the flavour turns harsh and burnt, that is the wick failing, and no amount of charging reverses it.
This is the most common misunderstanding about the whole category. If you want a device that keeps going indefinitely, you want a refillable one from our vape pods or vape kits ranges rather than a rechargeable disposable.
Screens, and whether they are worth anything
Most of the larger Gcore devices carry a small display showing battery level and liquid level. The battery indicator is genuinely useful, because it tells you when to charge before the device starts underperforming.
The liquid indicator is less reliable. These are usually estimated from usage rather than measured directly, so they drift, and a device can show liquid remaining when the wick has already started to dry. Trust the taste over the display.
Neither indicator changes how the device performs. If you are choosing between two models and one has a screen, treat it as a convenience rather than a reason to pay meaningfully more.
The five devices and who each suits
The G32 at $22.99 is the compact option and the one to choose if the device is going in a shirt pocket or a small bag. The Aura at the same price is the alternative at that size, differing mainly in shape and draw.
The Boost at $24.99 sits in the middle. The GC20000 at $24.99 steps up capacity substantially for the same money, which makes it the value pick in the range for anyone vaping daily.
The GT40000 at $29.99 is the largest and is aimed squarely at heavy daily use. It is a substantial object and it is not discreet, which is the honest trade for the capacity.
The Canadian Gcore range compared
All five are disposables, which makes comparison unusually straightforward.
| Device | Price | Relative capacity | Rechargeable | Best suited to |
|---|---|---|---|---|
| Gcore G32 | $22.99 | Compact | Usually | Pocket carry, lighter use |
| Gcore Aura | $22.99 | Compact | Usually | Pocket carry, alternative draw |
| Gcore Boost | $24.99 | Mid | Yes | Daily use, balanced size |
| Gcore GC20000 | $24.99 | High | Yes | Daily use, best value in the range |
| Gcore GT40000 | $29.99 | Highest | Yes | Heavy daily use, fewest purchases |
On cost per millilitre the larger devices win clearly. On practicality the smaller ones do. Buy for how you actually vape rather than for the largest number on the box.
Flavour life in a high capacity device
The genuine weakness of very high capacity disposables is that the coil has to survive as long as the liquid. In a five thousand puff device that is not much of a test. In a forty thousand puff device it is.
What tends to happen in practice is that flavour declines gradually across the life of the device rather than staying constant and then stopping. The last quarter often tastes noticeably duller than the first. That is the coil ageing rather than the liquid degrading.
Slower, gentler draws and a few seconds between them genuinely extend how long a coil stays good, because the wick has time to reabsorb. Chain vaping shortens the good period substantially in any device but most noticeably in the large ones.
Getting the most out of a Gcore device
Charge it before it is completely flat rather than running it down each time. The coil performs poorly at low voltage, and a device run repeatedly to nothing tends to taste worse in its final quarter than one kept topped up.
Keep it upright and out of heat. A device left on a dashboard in summer will leak and the liquid will degrade. Keep it out of deep cold too, which temporarily reduces battery capacity and can make a healthy device read as dead, a point we explain in vaping in cold weather.
Use the supplied cable with an ordinary phone plug rather than a high output laptop charger. Recycle the device at a battery drop off point when it is finished, because the lithium cell inside is a genuine fire risk in household waste.
Common Gcore problems and fixes
No vapour and no light usually means flat, and a high capacity device that has been sitting unused for weeks often needs a proper charge rather than a top up. Try a different cable before concluding anything, since cables fail at the connector far more often than devices do.
A burnt taste with liquid clearly visible on the display means the wick can no longer keep up. That is the end of the useful life, not a charging problem, and it is the most common false fault report in the category.
Gurgling or spitting means the coil has been flooded, usually by draws that are too hard. Leave it upright for a few minutes. Our walkthrough at disposable vape troubleshooting covers the rest in order of likelihood.
How Gcore compares with other brands we stock
Against Lost Mary and Geek Bar, which also field very high capacity models, the competition is close and comes down to flavour preference and draw more than to specification.
Against the Canadian brands such as Vice, Allo and Flavour Beast, Gcore is generally the higher capacity option at a similar price, while those brands tend to have broader flavour ranges and, in some cases, refillable options alongside.
Against a closed pod system such as STLTH or Vuse, the trade is between having nothing to charge or maintain and having a lower running cost. Gcore is squarely a disposable brand and does not offer a reusable route.
Working out whether high capacity is actually cheaper
The instinctive answer is that a bigger device is better value, and on cost per millilitre that is usually true. But the calculation only holds if you finish the device while it still tastes good, and in this category that is not guaranteed.
Work it out from your own consumption rather than from the box. If a GC20000 lasts you a fortnight and still tastes acceptable at the end, it is excellent value. If the flavour has gone by day nine and you replace it anyway, you have paid for liquid you did not use and the smaller device would have been the better purchase.
Track how long one device actually lasts you before buying the next size up. Our disposable vape life calculator gives an estimate from your own habits, and vaping versus smoking cost calculator puts the annual figure against what smoking the equivalent would have cost. For heavier vapers, both calculators usually end up pointing at a refillable setup from our vape kits range rather than at a larger disposable.
Canadian availability and the rules that apply
Every Gcore product we list sits at or under the federal 20 mg/mL nicotine cap set out in Tobacco and Vaping Products Act. That is why Canadian versions are not directly comparable to the same model sold in markets with a higher ceiling, and it is worth knowing if you are reading international reviews.
Flavour availability is decided provincially rather than federally, so the range differs depending on where you live, and we track that in vaping laws by province. Because every device in this range is a disposable containing a lithium cell, the recycling obligation applies to all of them without exception.
We operate an age gate on every visit and ship only inside Canada in Canadian dollars. Carriers, timings and tracking are on our shipping and delivery page and faults on our returns policy page. Anything with a lithium cell travels in cabin baggage rather than checked luggage when flying, as Transport Canada lithium battery rules requires, and our guide to taking a vape on a plane covers the rest.
Common questions
Will a 40,000 puff device really give me 40,000 puffs?
No, and nobody in the industry seriously claims otherwise. That figure comes from a testing machine drawing a consistent two to three second puff. Real draws are longer and more variable, so roughly half is the honest expectation. Use the number for ranking devices, not as a forecast.
Why do Gcore devices need charging if they are disposable?
Because a battery large enough to vaporise twenty millilitres in a single charge would make the device impractically big. Recharging lets you finish the liquid already sealed inside. It does not extend the coil and it does not make the device refillable.
Can I refill a Gcore device?
No. None of them are designed to be refilled, and the coil is sealed in with the liquid. If you want a device that keeps going indefinitely, a refillable pod kit is the right format instead.
Which Gcore device should I buy?
The G32 or Aura at $22.99 for pocket carry and lighter use, the GC20000 at $24.99 as the best value for daily vaping, and the GT40000 at $29.99 if you want the fewest purchases and do not mind a substantial device.
Why does the flavour fade before the device is empty?
The coil has to survive as long as the liquid, and in a very high capacity device that is a long time. Flavour declines gradually as the coil ages rather than stopping suddenly. Gentler draws with a few seconds between them extend the good period noticeably.
Is the liquid indicator on the screen accurate?
Only roughly. These are usually estimated from usage rather than measured directly, so they drift. The battery indicator is genuinely useful, but trust your taste over the liquid display, because a device can show liquid remaining when the wick has already started to dry.
