OBS’s Engine RTA is in a class of its own amongst rebuildables. It’s easy to build on, easy to fill, has a large 5.2 mL capacity, and it vapes like a dream.
Sporting the classic velocity-style build deck with bottom juice ports, the OBS is one of the easiest decks we’ve ever built on and wicked. The OBS Engine offers plenty of room for even the largest coil types, including captions, juggernaughts, and aliens.
One of the main innovations of the OBS Engine is its unique filling mechanism. Like many popular geny-styled tanks, the Engine uses an oval-shaped juice port near the top of the tank for fill ups. Unlike many popular geny-styled tanks, the Engine doesn’t leak when it’s tipped. And all it took was a simple, yet ingenious addition — a sliding ring that seals your fill ports when you’re done.
The other innovation you’ll find on the Engine is its airflow design. At first look, its top airflow design may not look like anything new. But the large size and meticulous positioning of these ports creates an incredibly smooth vaping experience, while also keeping your tank much cooler than competing RTAs)
