OBS’s Engine Nano 25mm is a revised version of their most popular RTA to date. It delivers the same excellent airflow, simple fill mechanics, and high juice capacity, but now with a revised deck that’s ideal for single coil builds.


Most RTAs on the market fall into one of two categories.

Either they’re tight and highly restricted mouth-to-lungs, or they’re severely loose and open direct-lungs.

And while there are many vapers who’d prefer something in between—a restricted lung hit—there really aren’t a lot of options. So for years, vapers hunting for this elusive draw-style have been debasing their expensive MTL rebuildables by drilling holes in their airflow ports.

No more.

The OBS Engine Nano is the perfect restricted-lung-hit RTA. It offers that smooth-yet-snug pull that so many vape enthusiasts have been hunting for.

It achieves this with completely unique airflow and build-deck mechanics. Its large top-airflow ports are designed to smoothly channel air down the sides of the chimney, where it is precisely restricted before reaching your coils. Because the build deck doesn’t make contact with any other parts of your tank, even with a restrictive airflow, your tank stays relatively cool.

The end result is an incredibly flavourful and satisfying vape—one that can’t be matched by any other RTA on the market.
