The vape shelf splits into two hardware families, and picking between them is less about the oil and more about how you like to shop. Here’s the honest comparison — capacity, cost-per-gram, convenience — without the vape-shop jargon.
510 cartridges: the refill model
A 510 cart is a threaded glass cartridge that screws onto a rechargeable battery you own. The “510” is just the thread standard — near-universal, which is the format’s superpower: any brand’s cart fits your battery.
The case for carts: you buy the battery once and then pay only for oil, which usually makes carts the better cost-per-gram over time. Batteries offer adjustable settings and USB charging, and swapping between two carts is trivial. The friction: you own hardware now — it needs charging, and a dead battery with a full cart is the classic Friday-night failure mode.
Disposables: the all-in-one model
A disposable is oil, battery and mouthpiece sealed into one unit. Use it until it’s done; nothing to charge (though many now include a top-up USB port), nothing to maintain, nothing to lose except the whole thing.
The case for disposables: zero setup, zero maintenance, pocketable, and the right call for occasional use or travel-light nights. Formats like the 3-gram disposables that move through our vape shelf carry serious capacity now. The friction: you’re re-buying the battery with every unit, which shows up in cost-per-gram, and a sealed unit can’t be rescued if the hardware hiccups.
The cost-per-gram math
Same arithmetic as flower: divide price by grams of oil. A $45 gram cart against a $45 three-gram disposable is $45/g versus $15/g — but capacity claims only matter if the hardware delivers all of it, which is where sealed disposables carry a little more risk than glass carts you can see into. Our listings state the format and capacity plainly so the division takes five seconds.
Which fits how you shop?
- Regular rotation, value-focused: 510 carts. Battery pays for itself quickly.
- Occasional, spontaneous, or travelling: disposables. Nothing to remember to charge.
- First time on the vape shelf: a disposable answers “do I even like this format?” without hardware commitment; graduate to carts if the answer’s yes.
One practical note for delivery
Both formats hate summer car interiors and winter doorsteps — oil viscosity shifts with temperature. Same-day delivery across Brampton and Mississauga means your order rides in a climate-normal car for an hour, not a courier depot for a week, which is genuinely the better logistics story for vapes. Both formats, current stock, on the vapes shelf.
