Here's the comparison. The IVG Bar 3000 holds 8mL of 20 mg/mL nicotine salt e-liquid and is rated at 3,000 puffs. Drip'n by Envi 8mL also holds 8mL of 20 mg/mL nicotine salt e-liquid, and it's rated at up to 16,000 puffs. Same volume, same strength, and one rating is more than five times the other.
The e-liquid itself doesn't explain that gap — there's the same amount of it. What differs is how each device uses it and how each rating was measured.
Start with how much liquid each puff consumes. That depends on the coil and the power behind it. A device that sends more power to its coil vaporizes more liquid per puff, which gives a bigger draw but uses the reservoir faster. A device tuned to run gentler, with less vapour per puff, stretches the same 8mL across many more puffs. Neither approach is wrong; they're different trade-offs between the size of each puff and the number of them.
Then there's how the rating is measured. Puff ratings are produced under test conditions — a set length of puff, a set pause between puffs. There isn't one universal standard every manufacturer follows, so a "puff" in one brand's test may not be the same length as a puff in another's. A shorter test puff produces a higher number from the same reservoir.
Put those together and the lesson is simple: puff ratings are useful for comparing products within one brand's lineup, and much less reliable for comparing across brands. If you want a fair comparison between two different makers, the e-liquid volume is the more honest number. It tells you how much you're actually getting.
That's why this site lists e-liquid volume alongside the puff count wherever the manufacturer provides it. The IVG Bar 3000 and the Drip'n by Envi 8mL both hold 8mL. In terms of raw material, you're getting the same amount of e-liquid from either one.
So how do you choose between them? Try thinking about the feel rather than the number. A device rated for fewer puffs from the same volume is likely using more liquid per puff, which often means a fuller draw. A device rated for many more puffs from the same volume is likely delivering a lighter draw per puff. Your preference between those two is the real deciding factor.
Flavour range is the other practical difference: the IVG Bar 3000 comes in five flavours, and Drip'n by Envi 8mL in ten.
Battery plays a part in how long a device lasts, too. A disposable only runs until its battery or its e-liquid runs out, whichever comes first. Some disposables recharge so the battery never becomes the limit; others don't. Checking the product page for whether a device is rechargeable tells you which situation you're in.
Strength here is the same on both: 20 mg/mL, which is also the maximum any vaping product can legally contain in Canada. You won't find a stronger legal product from anyone.
Orders to Tompkins are sent from our Saskatoon location by tracked courier, and the recipient's ID is checked on arrival just as the buyer's is at checkout. Most orders arrive within a couple of days; same-day delivery only applies inside Saskatoon.
Our range is sourced through authorized Canadian distributors, with the federal excise stamp on every item. And in Saskatchewan, only specialty vape retailers and online sellers can offer flavoured vaping products beyond tobacco, mint, and menthol — Tompkins included.
Ordering one device is fine; there's no minimum and no membership, and the full total is shown before you confirm.
A few more things are worth knowing when comparing disposables.
Strength and volume together tell you the total nicotine in a device, since strength is a concentration. Two 8mL devices at 20 mg/mL contain the same total, regardless of how many puffs each claims.
Coil design affects how evenly a device uses its liquid. Mesh coils, which heat across a flat surface, tend to vaporize more consistently than older wire coils, and that consistency affects both flavour and how steadily a device works through its reservoir.
Some devices have multiple power modes, which changes the maths again. A rating is usually based on one setting, and a higher mode uses more liquid per puff. When a listing mentions modes, it's safest to assume the rating reflects the gentler one.
The practical upshot for buying: use e-liquid volume to compare value across brands, use the puff rating to compare within a brand, and use your own preference for draw feel to decide between them.
For the two here, both hold 8mL. If you like a fuller draw and don't mind a device that works through its liquid faster, the IVG Bar 3000 is the one. If you prefer a lighter draw spread over more puffs, Drip'n by Envi 8mL is the better fit.
Whichever you pick, take it to a battery or electronics recycling drop-off when it's finished, since disposables contain lithium batteries. Keep spares at room temperature and out of reach of children and pets. And if you've been choosing disposables by the biggest number on the box, try comparing e-liquid volume on your next order — it's the more honest measure of what you're getting, and it takes seconds to check. Tompkins, a village of 153 holding steady, gets both delivered the same way.
