Uwell - Crown IV (Crown 4) Tank

Sold out

From Uwell, the Crown IV (Crown 4) Tank is the newest addition to the Crown series.

Made from with a stainless steel frame, the Crown 4 is a sturdy, well polished tank.

The Crown IV (Crown 4) Tank features a classic bubble glass, holding up to 6mL of e-liquid. Included with in the package is a 5mL sized straight glass.

The Crown IV is easily filled from the built in, top filling system. The top twists off easily to allow refilling.

Three airflow holes at the bottom of the tank allow for complete customization for your airflow. Fully open, fully closed, or anywhere in between.

Two coils are included with this kit:

1x 0.2 Ohm Coil - Installed - 60 to 70W

1x 0.4 Ohm Coil - Included - 70 to 80W

Both of these coils are made with a material not used before in the vape industry. SS904L. SS904L is a higher grade stainless steel, commonly used in high end watches, allowing for longer coil life and better flavor.

Coils are popped in through the bottom. This allows for easier coil replacement. All you have to do is unscrew the bottom airflow chamber, pop the old coil out, and insert a new one.

Uwell has always created tanks that are good with not leaking, and the Uwell Crown IV (Crown 4) Tank absorbs e-liquid in a condensation holder, then the vacuum pressure from you inhaling through your tank pulls the e-liquid back up into the tank. This stops e-liquid from leaking out of your tank.
