My containers appear to have a larger spout than some which has actually been hard in some sets (cough Smok N18) however I had no concerns with the fill port below.

However the filling up procedure is not constantly mess complimentary, I commonly wind up with e-liquid remaining on the top of the vessel which you require to rub out prior to changing the mouth piece to avoid a large glug of e-liquid in your mouth.

Exactly How Does the Uwell Caliburn AK2 Perform?

0.9ohm UN2 Fit together A2 Vessel

I understand this seems extremely careless however I will certainly refer you to the evaluation of the Caliburn A2 for the vessel efficiency.

This makes use of specifically the exact same vessels – and also I am also proceeding utilizing the vessel I utilized in the A2 package – to obtain an excellent suggestion of coil life.

Up until now I have actually had 33 refills (around 66ml) from the exact same vessel and also the flavour is still best!

As a recap this is flawlessly delighted with 50/50% PG/VG e-liquid and also 64%VG fluid as well.

The flavour and also throat hit are also much better than the initial Caliburn which was rather ace currently!

Uwell Caliburn AK2 Air Movement

Once Again this coincides as the Caliburn A2 – significantly the like the initial Caliburn as well.

Not the tightest MTL air flow I have actually experienced however still fairly limited and also to me definitely place on.

Uwell Caliburn AK2 Mod Efficiency

The mod done flawlessly, the automobile draw shooting is extremely fast and also I had no mistakes whatsoever.

As you will certainly see listed below the major trouble for me is the reduced battery ability nonetheless the mod fees swiftly and also I have actually had no USB port concerns either.

Uwell Caliburn AK2 Battery Life

This is constantly variable as a result of your very own vaping routines however as an overview I navigated 4-5 hrs of vaping.

It is such as pity the battery ability was not raised as this restrictions my use the package out and also regarding regretfully.


  • Such a little cutie
  • Wonderful flavour and also throat hit
  • Lanyard is truly convenient to bring this package
  • Automobile draw functions flawlessly
  • Air flow is definitely place on
  • Good billing time
  • Wonderful coil / vessel life! 66ml up until now!


  • No USB cable television consisted of – little bit thrifty!
  • Seeing home window is exceptionally dark
  • No fire switch – if your Automobile Attract system falls short (it did on among my initial Caliburns) the package is scrap
  • I do desire the battery ability was raised

Last Testimonial Judgment

There are naturally a couple of complaints regarding this package – regretfully absolutely nothing is ever before best.

They are so comparable to the Caliburn A2 too – no USB cable television consisted of, reduced battery ability, the checking out home window is not a great deal of usage and also the absence of fire switch are points I would certainly boost.

However I in fact choose the experience of utilizing this package to the A2 – having the lanyard implies I can use this around my neck so it is constantly available.

I am a woman so I hardly ever have actually any kind of good sized pockets and also vape kits obtain shed in my foolish stuffed bag!

The flavour, vapour and also throat hit are much better than the initial Caliburn which was great! Contribute to this the extremely fast draw fire and also outright cuteness of this package and also I truly can see me and also the AK2 remaining with each other for a long period of time!

Please Uwell boost the battery ability – there are great deals of comparable tools with a 1000mAh battery and also this would certainly be such a remarkable upgrade.

Having just 5 hrs of vaping implies I don’t constantly take this package out with me and also get my Innokin Sceptre rather as I understand that will certainly last me over a day.

If the Caliburn A2 was “Pod kit of the year” product – after that the AK2 is one more! I truly suggest it!

I will certainly maintain this in turning with my Sceptres and also have also place the A2 back in package!

It’s out the marketplace yet, however is this a sheathing package you’re eager to attempt and also get?
