Feel like royalty with the Uwell Crown 4 tank! This tank has a 6 mL pre-installed bubble glass so you will have plenty of space to fill this sub-ohm tank with your favorite juice right out of the box. The base has a 28mm diameter so it’s a little bigger than most but will still look great on most mods. What’s really great about this particular tank is the craftsmanship. Uwell put a lot of care into this product and it shows!

The Crown IV has a patented self-cleaning technology which absorbs excess e liquid in the condensation holder located at the  bottom of the tank, prepping it for vaporization. This effectively reduces leakages and the amount of times the tank needs to be cleaned!

This is a twist to open top fill with four openings making refilling very simple. The top cap is also rocking an 810 drip tip. The tank is made from stainless steel giving it not only a classy look, but giving you the peace of mind that it won’t fall apart on you! Replacing the Crown 4 coils is a snap - literally! To swap coils you simply pull them out then pop in the new on; no screwing in required! Having said that, the Crown IV comes with two high quality stainless steel (SS904L) dual coils: a pre-installed 0.4 ohm coil with a range of 60w-70w and a 0.2 ohm coil with a range of 70w-80w.  Both vape wonderfully, especially with the three adjustable airflow holes located at the bottom!

Treat yourself with a little class and grab the Crown IV today!

    Haven't had that many tanks but these are the best.
    I'm now vaping the with the .23 mesh coil with a temperature control mod. I recently learned that this stainless steel coil's (ss904L) TCR was .00085. (I set the temperature to 432° and watts at 69w, It works great.

    So, I bought this tank bc I already have 2 Crown 4 tanks, & they're, by far, the best tanks I've ever used, primarily bc the airflow is superior.

  • Love it!
