Vnook CO2 Seltzer Chargers 40-Count Silver — 8g Cartridges for Handheld Soda Makers & 1L Siphons

Vnook Leland CO2 seltzer chargers are a 40-count pack of silver 8‑gram CO2 cartridges designed to carbonate water and beverages at home for compatible soda makers and 1‑liter/quart siphons.

These compact, single‑use CO2 canisters offer an affordable way to fizz water, cocktails, and other drinks without reconnecting bulk tanks. They come packaged as forty silver cartridges and are sized to work with many handheld soda makers and traditional soda siphons. Before use, check your device compatibility: some brands require specific cartridges or differ in threading and pressure tolerance.

Which devices will these cartridges work with?

The Vnook Leland chargers fit a broad range of handheld and siphon-style soda makers that accept 8‑gram CO2 capsules. They are suitable for Hamilton Beach handheld soda makers and most 1‑liter/quart soda siphons, including popular brands like ISI, LISS, and Mosa. However, they are not universal across every model—always confirm the cartridge size and threading on your machine.

• Compatible: Hamilton Beach handheld soda makers.
• Compatible: 1 L / quart siphons such as ISI, LISS, Mosa.
• Not compatible: Soda Sparkle and Isoda Drinkmate devices.
• Works with: many appliances accepting 8‑gram CO2 capsules.

How should I use and store these CO2 chargers safely?

Handle cartridges with care: keep them sealed until ready to use, do not puncture outside a compatible dispenser, and avoid exposing them to high heat. Store the unopened canisters in a cool, dry place away from direct sunlight and temperatures above recommended limits. Dispose of spent cartridges according to local recycling or waste rules.

• Use only with compatible soda makers and siphons.
• Keep cartridges sealed until installation.
• Store in a cool, ventilated area away from heat sources.
• Follow device manufacturer instructions for installation and disposal.

How many drinks will a single cartridge produce?

One 8‑gram CO2 cartridge typically carbonates one standard 1‑liter bottle or several smaller servings, depending on your desired fizz level. Heavier carbonation or multiple charges per bottle will use more CO2 per serving. The 40‑count pack is convenient for regular home use, gatherings, or keeping a ready supply for frequent carbonation needs.

• Average: one cartridge per 1 L bottle at moderate carbonation.
• Higher fizz: may require additional cartridges per bottle.
• Pack size: 40 cartridges for extended use and backups.
• Good for: water, cocktails, and small beverage batches.

Are these cartridges interchangeable with other brands like Mr Fizz or Fizzini?

The Vnook Leland cartridges share the common 8‑gram size used by many makers, so they are compatible with devices that accept that standard. Note that Mr Fizz 8‑gram cartridges are known to fit Fizzini machines; cross‑compatibility can vary by model, so verify threading and pressure requirements before substituting cartridges in your appliance.

• Standard size: 8 grams, matching many cartridge systems.
• Mr Fizz 8g cartridges: compatible with Fizzini—check specifics for interchangeability.
• Always confirm device specs for safe use.
• Not all branded machines accept universal cartridges.

Who is this for: The Vnook Leland 40‑count CO2 pack is ideal for home entertainers, people who make sparkling water or cocktails frequently, and owners of compatible handheld soda makers or 1‑liter/quart siphons like ISI, LISS, and Mosa. It offers an economical stock of cartridges for regular carbonation without the hassle of refilling larger tanks. If you own a Soda Sparkle or Isoda Drinkmate, choose cartridges specified by those brands instead.
