IJOY COMBO RDTA, another ingenuity work after IJOY Limitless RDTA, features interchangeable gold plated decks and pre-made coils. Users can use 7 decks (or coil) with the COMBO RDTA. With an optional RDA base, the combo can be assembled into COMBO RDA. So you will have a RTA/RDA/Tank/Atomizer. Side filling system, ceramic drip tip and 6.5ml e-juice capacity, all make the COMBO RDTA a must tank you need have.
