How does the XROS 3 compare to other Vaporesso kits?

The XROS 3 Nano sits within Vaporesso's pod kit range as their most compact option. It shares pod compatibility with the full XROS series but in a smaller format. The 1000mAh battery balances size with performance, whilst the AXON chip and pulse mode technology match larger models. For Vaporesso's complete lineup, browse our Vaporesso collection.

Is the XROS 3 Nano suitable for mouth-to-lung vaping?

Yes, the XROS 3 Nano excels at MTL vaping. The adjustable airflow switch lets you tighten or loosen the draw to your preference. The 0.8Ω and 1.0Ω pods deliver a tighter, more restricted inhale similar to cigarette smoking, making this kit ideal for those switching from cigarettes. The device works well with nicotine salt e-liquids for satisfying throat hits. If you're new to vaping, visit our stop smoking start vaping guide for transition support. 

What are the XROS 3 Nano colours available?

The XROS 3 Nano comes in several colour options to suit different preferences, including black, navy blue, olive green, lemon yellow, magenta red, and rose pink. The compact box-style design includes a sturdy lanyard port regardless of colour choice.

What pods work with the XROS 3 Nano?

The XROS 3 Nano uses XROS refillable pods compatible across the entire XROS series. The kit includes two pods: 0.6Ω for slightly warmer vapour and 0.8Ω for a cooler, tighter draw. You can also purchase 1.0Ω XROS pods separately for a more restricted, cigarette-like experience. All pods feature mesh coils with Corex Heating Technology and hold 2ml of e-liquid.

What e-liquids work best with the XROS 3 Nano?

The XROS 3 Nano performs best with 50/50 or 60/40 VG/PG e-liquids. These ratios balance flavour, throat hit, and pod longevity. Nicotine salts work particularly well, typically in 10mg or 20mg strengths. Thicker high-VG liquids may struggle to wick properly in the mesh coils, whilst very thin liquids could leak. For flavour recommendations, read our article on the best vape flavours.

How to fill Vaporesso XROS 3 Nano pods

Filling the XROS 3 Nano is simple. Remove the pod from the device, locate the silicone bung on the side, and lift it to reveal the fill port. Insert your e-liquid bottle nozzle and squeeze gently until the pod reaches the fill line. Close the bung firmly and wait 5 minutes before vaping to allow the mesh coil to saturate properly. This prevents dry hits and extends coil life.

Why is my XROS 3 Nano pod leaking?

XROS pods feature SSS leak-resistant technology, but leaking can occur if the pod isn't inserted correctly or the fill bung isn't sealed properly. Check that the pod clicks firmly into place, and the side bung sits flush. Overfilling past the maximum line can also cause leaks. Using e-liquids that are too thin (high PG) may lead to leaking; we recommend 50/50 or 60/40 VG/PG ratios for optimal performance.

How long does the XROS 3 Nano battery last?

The 1000mAh battery provides up to 48 hours of use on a full charge for moderate users. Heavy users might need daily charging, whilst light users could extend this to 2-3 days. Battery life depends on pod resistance, liquid viscosity, and draw length. The pulse mode maintains consistent performance even as battery depletes.

What is the XROS 3 Nano charging time?

Charging the XROS 3 Nano via USB-C typically takes 45-60 minutes from empty to full. The fast-charging capability means you can quickly top up between uses. An LED indicator shows charging status - it illuminates while charging and switches off when complete. Always use the included cable or a quality USB-C cable to protect the device.

Why is my Vaporesso XROS Nano blinking 3 times?

Three blinks usually indicates the device needs charging or there's a connection issue. First, try charging the device. If it still blinks, remove and reinsert the pod firmly until it clicks. Check the pod contacts and device connection points are clean and dry. If problems persist after cleaning and charging, the pod may need replacing.
