The Kanger T3D is an upgrade to the popular Kanger T3S clearomizer. The T3D is a bottom dual coil clearomizer rather than a single coil clearomizer like the T3S. Dual coil clearomizers ensure a good kick of flavour and vapour from your e liquid, as heat is transferred faster and more efficiently to the coils. The T3D is also bottom fill device and is made up of four parts which are the tube, the base, the coil/head and the detachable drip tip (unlike the T3S which has a fixed mouth piece). The T3D has 510 drip tip so can be swapped with alternative 510 drip tips. The T3D has a big 2.2ml capacity and is compatible with eGo series batteries but cannot directly be used with 510 threaded devices. For use with 510 devices, please purchase 510 to eGo Adapter.
