The OBS Engine MTL RTA (Rebuildable Tank Atomiser) has been designed for advanced users. Compatible with single coil builds only, this RTA has a 2ml capacity and has been designed for mouth to lung vaping. Fitted with a standard 510 pin, you can use the Engine with a range of vape mods.

Fitted with a raised postless build deck, this deck has been designed to concentrate heat for a fast ramp up and consistent vape. This deck allows single coils to be fitted straight away, with no pre-cutting required. The size of the terminals allows for a range of coil types to be fitted, including premade coils.

The 2ml capacity means that you’ll experience all of the flavour production of a standard rebuildable, without the constant need to drip. It can be refilled by removing the threaded top cap, which reveals two generously sized juice ports, with the overall seal helping to reduce the chance of leaking.

Top adjustable airflow and a narrow chimney provide a concentrated vape, with a tight mouth to lung inhale. Three airflow settings allow you to select a perfect balance between flavour and cloud production that suits your style. The MTL inhale is further accentuated by the 510 drip tip, which creates a cool vape.

Overall, the OBS Engine MTL RTA is ideal for vapers looking for a tighter inhale and discreet cloud production; whilst experiencing a stronger, more distinct flavour from eliquids.

Important information about Rebuildable Tank Atomisers:

This product is designed for experienced users, and for those possessing an Ohms reader or multimeter to test their coils on. This device requires a comprehensive understanding of the technicalities of vaping, along with knowledge of electronics and Ohm's Law.

We don't advise any beginners to start rebuilding coils without speaking to a knowledgeable shop. A rebuildable coil must be tested carefully on an ohms reader before it is used on a device. Not testing this properly may present a safety risk for the user, and no new coils should be used on an electronic vaping device until the coil is known to be safe.
