UWELL Crown III Preview: Is the Third Time a Charm?

The Crown III by UWELL is coming!

The new Crown III is a 24.5 mm tank that holds a whopping 5 mL of juice. And get this: it’s currently on pre-order from EFUN.top for $19.99! There are three new colors in addition to black and stainless—rainbow iridescent, sapphire blue, and matte black—as well as 9 different drip tip colors to mix and match. It also features an improved chimney design that is supposed to minimize the potential for leaking and condensation, and there’s a new coil system.

But UWELL has made the new coil system a “plug-pull” coil swap in lieu of the threaded bullet-style heads, and there is a new airflow system to the heads. Previously there were four bottom airholes, but now there are three slots. It may seem minor, but the coil heads account for a huge percentage of how well a tank performs, and a minor tweak can make all the difference in the world.

Let’s hope these Crown 3 heads perform up to the og Crown’s status!

Game of Crowns


Some of you may remember when the Crown tank was the hottest thing on the market. It seems like several years ago, but it was just mid-2015. Not even a full two years. Wow!

The original 22 mm Crown was manufactured and designed well, it came with long-lasting coils that could withstand some heat, and the stainless-steel (wire) coils were the first of its kind for a sub ohm tank—they could be used in wattage or temp control mode. Back then, the Crown put out crazy good flavor and exceptional clouds. For many months, it was top dog!

But after a while, the tank started getting more negative reviews. The coil consistency started getting iffy, and then it didn’t help that SMOK captured everyone’s attention with the TFv4. Many of us just moved on from UWELL.

UWELL eventually responded with a version 2. It was a beautiful tank which met and exceeded all objective standards of the original Crown, but many felt it lacked heart… at least in the flavor department.

The Successor


At first glance, the Crown III doesn’t appear to be massively different from the v2, though the Crown emblem on the chimney is kinda sweet.

The main differences between this and the v2: an additional 0.5 mm to the diameter, the removal of 0.8-ohm coil heads and Ni200 coil heads, and there is now a key to unlock the top portion of the tank for easy cleaning (that should’ve been included in the second version). No mention yet on an RBA deck. There’s a new and improved chimney, and a new plug-pull coil system with updated airflow.

The “plug-pull” coil system sounds like it’s like the Vaporesso EUC coil head. This should address the problems that some vapers had with the threaded connection of the coil heads of the v2. But it remains to be seen if these new coils will catapult the Crown III back to the status that UWELL used to occupy. They say the third time is a charm. For UWELL Crown fans, let’s hope that is true.
