Simba Subtank by UD

The Simba Subtank is a convertible tank that can either be used with the supplied RBA head or with a selection of replacement heads. Liquid control is featured on this tank along with an easy top-fill port under the top cap. This tank offers a nice amout of air flow and can be adjusted to suit your vaping style. The Simba also features pourous ceramic rings in the base parts to soak up any condensation or excess liquid that may make its way down into the bottom to prevent or reduce the amount of leakage. The new Simba SCC (solid ceramic coil) design heads use no cotton and should provide a long life-span, clean flavour, and dry hit prevention.

The included RBA head has a large 3.4mm air hole under each coil and the kit includes an extra part to use to block off one side of the deck if you prefer to build a single coil. Replacement heads are available for the Simba tank if you should choose not to use the RBA head in this kit.

We advise you clean the unit and all parts fully before using to ensure no manufacturing residues remain.

As with all rebuildables/convertibles, the Simba is an advanced user device and the RBA functionality requires the willingness to experiment to get the best out of it for your own individual and unique vaping style. We strongly recommend you test any coils you produce with a multimeter before using to avoid risk of damaging your battery. If you choose to use the sub-ohm coil contained in this kit, you do so entirely at your own risk and must make sure the battery device you are using is fully capable of safely supporting the required drain rate. We strongly recommend you thoroughly research the topic before embarking on any experiments with sub-ohming. We will not accept any responsibility for any damage caused by sub-ohming activity.

Return requests for any reason other than a genuine manufacturing fault will not be accepted.
