Adjustable Airflow for MTL or RDL Vaping
Whatever your preferred vaping style, there’s an airflow to suit you. You can easily adjust the airflow hole to your preferred experience.

Easy Coil Changes
The new design has a push fit system for an easy change of coils. The tank also has a valve which will close when the coils are removed which stops any e liquid from escaping, which is a very nice touch from Aspire.

Easy Refilling of E-Liquid
The Nautilus 3 tank’s filling system has been upgraded to an easy filling system, which makes filling your tank a breeze. For new coils, make sure to prime the coils by filling them with e-juice and then allowing it to soak in for several minutes before activating your vape kit.

Durable Mod Battery
Now, lets move on to the Zelos 3 MOD battery. This is an 80w device made from zinc and aluminium alloy which makes it very durable. The device has a rounded design which is very comfortable in your hand. Let’s take a look at some of the features, making it a vast improvement from the original Zelos mod. The Zelos 3 Mod also has an enormous 3200mAh inbuilt battery capacity, which lasts the majority of vapers a full day on a single charge.

Coil & E Liquid Compatibility
Choosing the Aspire brand of electronic cigarette kits is an easy choice, being one of the longest and most respected manufacturers in the vape industry. With the Zelos 3, as mentioned above, there is a wide range if coils to choose from, each with a different vaping experience. Next you’ll need to work out which coils you plan to use, which then helps you determine suitable e liquid options.
MTL Vaping
This kit has the choice of 2 vaping styles available simply by changing the tank’s coils. The first vaping style is known as mouth to lung (MTL) vaping, and is the most popular Aspire coil used in the vape community. These are the Aspire Nautilus BVC 1.8ohm or 1.6ohm coils. Both of these coils allow higher nicotine strength or salt nicotines to be vaped, giving the feel in your throat of having a smoke. The 1.6ohm allows a slightly higher wattage and therefore more vapour production, although your battery and juice won’t last as long compared with the 1.8ohm coils. These MTL coils are recommended for use with lower VG e liquids, such as the Vapour Days UK 10ml bottles or the Cherub brands of flavours.
RDL Vaping
The above MTL coils are best for smokers wanting to switch to vaping due to the ability to vape higher nicotine strengths. If you are a low volume smoker, or have quit smoking, then a restricted direct to lung (RDL) coil is an alternative option. The main type of RDL Aspire coils compatible with these kits is the Nautilus 2S 0.7ohm Mesh wicks or the Nautilus 2S 0.4ohm coils, with one included in the Zelos 3 kit contents. These coils are still ideal for lower VG e liquids including the Vapour Days UK 10ml bottles or the Cherub brands of flavours. RDL coils produce more clouds and therefore are recommended for use with lower nicotine strengths. You can also use some higher VG e liquids, up to 70% VG, which opens you up to using the majority of the bigger short fills available at Vapour Days UK too. These have no nicotine although there is the option to add a nicotine shot to create a low 3mg bottle of juice.
CBD Vaping
The Aspire Nautilus 3 replacement coils also cater for vaping with CBD e-liquid. Orange County is the best-selling brand with a wide range of flavour options. The Aspire Nautilus BVC 1.8ohm or 1.6ohm coils which are recommended for CBD due to their efficient, low-wattage performance. Orange County is a well-known CBD brand with a wide selection of flavors, making it a popular choice among users.
Optional Bubble Glass Upgrade
The Aspire Nautilus 3 tanks have an optional 5ml bulb glass for increased juice capacity and an enviable look. These replacement glasses are only £3.98 and take this tank to a whole new level.
Charging
Please note that these Zelos / Nautilus 3 kits, like most electronic cigarettes on the market, should be charged with a wall plug of 2amp or less in power. Most phone and other plugs are typically higher than 2 amps and therefore will damage the batteries in vape kits.
