The UWELL Crown sub-ohm tank is the first ever sub-ohm tank manufactured by a Chinese company, Shenzhen UWELL Technology Company, back in 2015.

This baby, although manufactured by a relative rookie in the world of vaping, has been getting rave reviews since it was released. We decided to get to the bottom of this and to test for ourselves whether it lives up to the hype.

The Kit: Let’s Take a Look at What’s Inside

This is, by far, the most complete clearomizer kit we’ve ever come across – and it’s pretty cheap!

When the package was delivered, we got the following included:

  • 1 UWELL Crown tank
  • 25-ohm stainless steel coil, for 20-120 W
  • 15-ohm Ni200 temperature control coil
  • 5-ohm stainless steel coil, for 30-80 W (pre-installed)
  • a replacement tank section, O-rings, and, the user manual

Keep in mind that the RBA deck needs to be purchased separately. This isn’t a deal-breaker by any means, but does detract from the kit’s completeness.

Nifty Features

Physically, everything on the kit looked pretty remarkable. It’s constructed using food-grade stainless steel, which not only looks roguishly handsome but is also pretty tested and safe for everyday use.

The glass tank is made of quartz, and we can confirm (after a couple of test drops) that it is very tough and can take sume abuse. It’s also a better material compared to Pyrex tanks, since it regulates heat more effectively.

Another feature that the tank also has a nice airflow adjuster, dual airflow holes and a wide bore drip tip that’s perfect for making huge clouds of vapors with each hit.

Crowning Achievements

The best feature, and one unique to the UWELL Crown sub-ohm tank, is the double-sided tank filling feature. We tried this feature out, and found it singularly convenient: what’s great is that you can fill it from either the bottom or the top.

We didn’t really have to fill it up at the top or remove it from the vape mod while filling it. Plus, the refilling process was a pretty easy task; we didn’t even have any issues with leaks.

We also have to mention, of course, the amazing durability of the coils. Replacing coils can be one of the most daunting, and expensive, parts of owning a vape, so we really appreciate that UWELL’s coils are made from 100% Japanese cotton. This high-quality cotton is the reason why their coils last for up to 2 months without needing a replacement!

Clouds and the Flavor

Since the UWELL Crown sub-ohm tank comes with different coil sizes, we tested them out one by one. Cloud-chasers will appreciate that the Crown can go as high as 100W when used with the 0.25-ohm stainless steel coil. The Crown delivers strong flavors without aftertaste, and you can fog up a room with just one hit. That’s how powerful the UWELL Crown sub-ohm tank is.

Unlike other clearomizers and atomizers that make promises but don’t deliver, this tank does what it advertises and more. It’s the perfect tank to maximize your vaping experience. Clouds are thick and huge, while flavors are splendidly intense.

For best results, make sure to let the coils soak in the juice before you start vaping – a good 25 minutes should be enough.

Cleaning and Replacement

Another feature that we really enjoyed about this tank (in addition to the features mentioned above) is how extremely easy it is to take apart and clean.

The kit already includes most major replacements you’ll need, and with enough variety to experiment with them as you go. This tank is compatible with most major mods on the market, so you won’t run out of options when you’re trying to look for the perfect combo.

Our Final Thoughts

The UWELL Crown sub-ohm tank is indeed buzz-worthy. It’s made from sturdy, safe materials that you won’t break anytime soon; it’s easy to clean; and it is, in every sense of the word, remarkable. For a price that won’t break the bank, you have a powerful clearomizer that delivers even more than what you’d hope for.

The rave reviews across the globe have it right: the UWELL Crown sub-ohm tank is the best in the market when it comes to convenience, performance, quality, and durability.
