Choosing between two vape systems can be surprisingly difficult when they come from the same brand. On paper, the IVG Pro and IVG XL35 have plenty in common: both are rechargeable, reusable pod systems designed around a mouth-to-lung (MTL) vaping style, and both use IVG's connectable refill approach.

The important differences are in the details.

The IVG Pro 12 is built around portability and simplicity, while the IVG XL35 takes the same general concept and adds a larger refill capacity, a bigger battery, a display and adjustable Eco and Boost modes. Neither is automatically the better option. The more suitable system depends on what an adult user actually values.

IVG Pro vs IVG XL35 at a Glance

The current IVG Ireland listings show some clear differences between the two systems:

IVG Pro 12

• 1000mAh rechargeable battery

• 2ml pod + 10ml refill container

• Manufacturer/store puff claim of up to 10,000 puffs

• MTL vaping

• Mesh coil

• LED battery indicator

• Auto-fill system

• Compact, pocket-friendly design

• Available in different nicotine strengths depending on flavour

IVG XL35

• 1100mAh rechargeable battery

• 2ml pod + two 10ml refill containers

• 22ml total refill system

• Manufacturer/store puff claim of up to 35,000 puffs

• 18W maximum output

• Dual 1.1Ω mesh coils

• Smart display

• Eco and Boost modes

• Aluminium construction

• Current range listed at 20mg nicotine salt

These specifications come from the current product listings and should be treated separately from independent performance testing. Puff figures in particular are estimates rather than a guarantee of how long every user will get from a refill.

Size and Portability

This is one of the easiest differences to understand.

The IVG Pro 12 is positioned as the more compact option. Its pocket-friendly design makes it straightforward for users who want something relatively discreet and uncomplicated for everyday use.

The XL35 is more substantial because it houses a larger refill system, 1100mAh battery and display. That additional hardware brings more functionality, but it also means the device is aimed less at minimalism and more at extended use.

If portability is a priority, the Pro has the simpler proposition. If capacity and additional controls matter more, the XL35 becomes more interesting.

Battery Differences

The battery difference is relatively modest: the Pro 12 uses a 1000mAh rechargeable battery, while the XL35 uses a 1100mAh battery.

On its own, that 100mAh difference does not tell the whole story. Battery life depends on factors such as power output, puff duration, frequency of use and operating mode.

The XL35 also gives users Eco and Boost modes. Eco mode is intended to prioritise battery longevity, while Boost increases the power/performance emphasis. The Pro, by comparison, keeps the experience more straightforward rather than giving users multiple operating modes.

Pod Capacity Is the Major Difference

The biggest practical difference is the refill system.

The IVG Pro uses a 2ml pod with a 10ml refill container. The XL35 uses a 2ml pod together with two 10ml refill containers, giving a combined 22ml system.

That larger capacity is reflected in the advertised puff figures: up to 10,000 for the Pro compared with up to 35,000 for the XL35.

However, it is worth being careful with those numbers. They are product claims, not a fixed number of puffs every user will achieve. Longer draws, frequency of use and device settings can all affect consumption.

This means the XL35's headline number should primarily be understood as an indication of its larger-capacity design rather than a promise of exactly 35,000 puffs.

Display and Controls

Another major distinction is how much information and control the device provides.

The Pro 12 keeps things relatively simple with an LED battery indicator. It is designed around the basic functions an adult user needs: insert the compatible refill, charge the battery when necessary and vape.

The XL35 introduces a smart display that provides information such as battery status and charging information, alongside its Eco and Boost modes.

For users who prefer a straightforward device, extra controls may not be necessary. For others, having more information visible on the device can make it easier to manage daily use.

Coils and Flavour Performance

Both systems use mesh coil technology, but the XL35 uses dual 1.1Ω mesh coils and is rated at up to 18W. The Pro listing also specifies an advanced mesh coil but is positioned around a simpler MTL experience.

It would be misleading to say that one automatically produces “better flavour”. Flavour perception depends on the e-liquid, nicotine strength, coil condition, draw style and individual taste.

The XL35 does, however, provide more control over its performance through its Eco and Boost modes, which can change how the device operates.

Which One Is Better for You?

The answer comes down to priorities.

The IVG Pro 12 makes more sense for an adult user who values a compact device, straightforward operation and a smaller refill system. Its 1000mAh battery, simple indicator and 2ml + 10ml refill format keep the system relatively uncomplicated.

The XL35 is better suited to someone who places greater emphasis on capacity and additional features. Its 22ml refill system, 1100mAh battery, smart display, dual mesh coils and Eco/Boost modes make it the more feature-focused of the two.

There is also an important compatibility point: these are separate refill ecosystems. IVG Pro refills are intended for the Pro system, while XL35 refills are designed specifically for the XL35. They should not be treated as interchangeable simply because both products carry the IVG name.

Final Thoughts

The IVG Pro and IVG XL35 are not really competing for exactly the same type of user. The Pro 12 focuses on compactness and simplicity, whereas the XL35 puts more emphasis on capacity, information and adjustable performance.

For someone who wants a straightforward reusable MTL system that is easy to carry, the Pro 12 is the more minimalist choice. For an adult user who prefers fewer refill changes and wants features such as a display and Eco/Boost modes, the XL35 offers a more substantial setup.

Both are part of the wider IVG range available through IVG Ireland, where adult users can compare compatible devices and refill options based on their own preferences. As always, nicotine-containing products are intended for adults only, and nicotine is addictive.
