Happy & Puff Pens & Cartridges

The Happy & Puff pens and cartridges collection brings together 38 cannabis vape pen and cartridge formats, from all-in-one disposable pens to refillable 510 thread cartridges, with a wide choice of cannabinoid profiles. Whether you are new to vaping or already know your favourite format, this range is built for simple daily use and steady vapour output.

Cannabis vape pens and cartridges: what is the difference

A vape pen is a complete unit: the battery and the cannabis oil chamber are built into one device. You charge it, draw from it, and when the oil is empty, you replace or recycle the whole pen. Pens are the simpler option and need no extra equipment. They are ready to use straight out of the packaging.

A cartridge is the oil chamber only. It holds the heating coil and the cannabinoid oil, but it needs a compatible battery to work. When a cartridge is empty, you remove it from the battery and attach a new one. This format creates less waste over time and lets you use different oil profiles with one device.

Both formats work in the same basic way: a coil heats the oil to a temperature below combustion, which produces vapour instead of smoke. The only difference is how the battery and the oil chamber are connected. Browse the Happy & Puff vapes collection if you want disposable or rechargeable pens and cartridges in one place.

510 thread cartridges: compatible devices and use

The 510 thread standard is the most common connection type in vaping. The name refers to the thread on the metal base of the cartridge. Because 510 is the default across the industry, nearly all compact vape batteries accept 510 thread cartridges without an adapter.

To use a 510 thread cartridge, screw it onto a charged 510 battery, choose your voltage setting if the device allows it, and draw slowly. Lower voltage settings keep more of the terpene flavour and extend the life of the coil. Stronger settings produce denser vapour but can hide part of the aroma. Most Happy & Puff cartridges work well between 2.8 V and 3.4 V.

If you do not own a compatible battery yet, the accessories collection includes 510 devices that fit the cartridge formats in this range. The filters in the product grid above make it easy to reorder your favourite oil by cannabinoid type.

Happy & Puff pens and cartridges: cannabinoid profiles

The Happy & Puff pens and cartridges range covers several cannabinoid profiles. THCA cartridges contain THCA, a cannabinoid that occurs naturally in hemp. T9HC and T8HC options are two related molecules with a different cannabinoid content per product. CBG cartridges are available if you prefer a CBG-based oil.

Terpene blends vary by product and shape the flavour and aroma of each draw. Strain-based profiles, including sativa-leaning and indica-leaning blends, are listed on each product page, together with the strain name and the terpene profile.

Some products in the collection combine two or more cannabinoids in one oil. The full list of ingredients and the cannabinoid content in % are shown on every product page. You can pair cartridges from this collection with Happy & Puff liquids if you also use open-system vape hardware at home.

How to choose between a vape pen and a cartridge

The choice comes down to two factors: convenience or flexibility. If you want the easiest start and no extra purchases, a disposable pen is the right option. Charge it, use it, and recycle it when it is empty. There are no batteries to buy, no cartridges to change and no voltage settings to manage.

If you vape often and want to switch between cannabinoid profiles without buying a new device each time, cartridges give you that option. One battery works with the full Happy & Puff cartridge range. Over several orders, this reduces both cost and packaging waste.

A third point is size compared with capacity. Disposable pens are usually slim and fit in a pocket. Cartridges come in different fill volumes, and the battery adds some size. For travel, pens are easier to carry. For use at home, a 510 battery with a few cartridges gives you more control over voltage and flavour.

Use the filters above to compare by format and cannabinoid profile, then add your preferred option directly to the cart.

All Happy & Puff pens and cartridges in this collection are tested by independent third-party laboratories. Certificates of analysis that confirm the cannabinoid content and check for residual solvents and heavy metals are available on the product pages. Availability depends on your delivery country. All orders ship in discreet packaging. For adults 18+ only. Keep all vape products out of reach of children.
