Product Care

Follow these simple steps to get the most out of your vape kit.

• For refillable devices, allow e-liquid to soak into the coil for at least five minutes before using the device.
• Always keep some e‑liquid in the pod or tank to ensure the coil is saturated.
• If using replaceable coils, push/screw them in firmly but don’t over tighten.
• For adjustable power devices, use recommended power settings for the coil or pod you are using (see box, coil or manual).
• When device is switched on, only press fire button when inhaling. This prevents condensation build up in the pod or tank.
• If using a refillable kit, use the correct e-liquid for the coil or pod you are using. See the product description for each kit for recommended e-liquid types
• Avoid filling refillable pods or tanks above the fill line or to the very top.

Battery advice

Do:

• Use the correct charging equipment for your device (see below). Use of third-party chargers may void your warranty.
• Charge batteries on a flat, hard surface.
• Turn your device off when not in use (if device comes with an on/off switch).
• Keep battery terminals clean. A quick swab with a cotton bud can improve performance and reliability.
• Always keep some charge in your battery.

Don’t:

• Use damaged batteries.
• Leave charging batteries unattended.
• Allow contact between your batteries and water.
• Carry batteries in a pocket/bag with coins or keys.
• Expose batteries to sunlight, extreme heat or cold.
