The coating is metal as well as the guidelines mention the product of the body is Aluminium Alloy, it does really feel incredibly light without being lightweight.

A home window has actually been offered to watch your e-liquid degree, however this is just eliminated on one side of the mod. This implies there is no light beaming with this home window as well as I have actually missed my e-liquid degree going down to Minutes almost every single time.

You can naturally turn the gadget as well as look for bubbles or fluid activity to see to it it isn’t vacant however the degree of fluid is tough to see.

I would certainly have suched as a comparable remove on the back of the mod to supply a little bit of light – keep in mind the images taken are under an extremely intense light – in daily utilize this home window is not excellent.

The fire switch rests on the front as well as is very receptive. This is a little recessed as well as does not stick out from the body in any way which ought to assist protect against unintended shooting in a pocket or bag.

Listed below the fire switch is some message in black stating “Caliburn”.

This is not a large bargain as although the Caliburn A2 will certainly stand on the base it is a little bit unsteady as well as will certainly fall over rather quickly so upright billing wouldn’t be feasible also if the port lay somewhere else.

Likewise on the base are the needed lawful logo designs.

Uwell Caliburn A2 Shell

I did attempt the initial Caliburn case in below as well as it doesn’t fit regretfully, the very same is additionally real for attempting the A2 case on the initial – they are not suitable.

The fill port gain access to on the A2 case is a lot far better, I had a hard time to eliminate the mouth piece on the initial as well as needed to attack it to draw it off.

This moment an easy press back and forth stands out off the mouth piece as well as when securely changed it does make a distinct click. It deserves dual monitoring this has actually been changed properly – if the mouth piece isn’t completely attached the case might leakage.

The fill port has a red check shutoff as well as additionally is a wonderful dimension for my 10ml e-liquid containers. My containers appear to have a larger spout than some which has actually been challenging in some packages (cough Smok N18) however I had no problems with the fill port below.

One more excellent function is that there is a tiny air vent port – so this enables air to get away from the case when loading avoiding unpleasant airlocks. This functions a reward!

It deserves keeping in mind that any kind of fluid in addition to the case after loading can either leak down the side of the case or wind up in your mouth – so it deserves cleaning the top of the case after loading.

I did additionally have 1 significant leakage – when the set remained in a bag – however I cannot be 100% certain that the mouth piece had actually been clicked right into location properly. So perhaps that was customer mistake.

The mouth piece form has actually been upgraded as well as still really feels very comfy.

Just How Does the Uwell Caliburn A2 Perform?

As this is primarily a MTL (Mouth To Lung) set I will certainly be making use of a 50/50 VG/PG e-liquid – Crazysaltzzz Bubblegum 11mg Nic salt stamina.

I additionally wished to contrast the efficiency in between the A2 as well as my 2 various other Caliburns however the Rainbow one is defective as well as I have no functioning shells for the Grey one – such an embarassment!

0.9ohm UN2 Harmonized A2 Shell

50/50 PG/VG E-liquid

This is suitable for this set – with my Nic Salt stamina I obtain a very gratifying throat hit as well as the mesh coil truly drain the flavour.

I enjoyed the initial as well as this is also much better!

High Nic or nic salts in a charming 50/50 mix of your much-loved flavour must suffice to encourage you that vaping is method extra enjoyable than cigarette smoking!

This is a starter set on top of its ready fulfillment!

Likewise worth stating thus far I have actually re-filled this a minimum of (I might have failed to remember to count refills when I was out as well as around) 13 times (26ml in overall) ! Flavour is still ideal.

64%VG/36%PG E-liquid

For this I made use of the Choppa Collection Blue Slush – I haven’t included any kind of pure nicotine to this so it has a 64%VG proportion.

This examination is simply primarily to see if the case can take care of thicker e-liquid. I am not anticipating a throat struck as I have no pure nicotine included in the fluid.

I did load the case as well as left it over night to see to it the fluid had actually absolutely saturated right into the coil.

The outcomes are great, the flavour is gorgeous truly singing out from such a tiny coil at reduced power!

No wicking problems in any way to report as well as this is still a lovely flavorful vape.

This fluid has some air conditioning in it so undoubtedly the inhale doesn’t have the typical heat however the flavour is unbelievable!

Uwell Caliburn A2 Air Flow

The air flow is ideal – the vehicle draw triggers very fast as well as doesn’t rise and fall on as well as off like some case packages.

This is not the tightest MTL air flow I have actually ever before attempted however it really feels to me to be the like the initial Caliburn – a limited MTL however not very limited.

Uwell Caliburn A2 Mod Efficiency

I have no problems in any way below, the vehicle draw fire as well as fire switch fire both job promptly.

There were not a problem with the USB port or billing – this is all round an easy dependable little set!

There appeared to be no decrease in efficiency as the battery fee diminished – which was a problem with the initial Cali.

Uwell Caliburn A2 Battery Life

This will certainly constantly differ because of your very own vaping behaviors however this is a harsh overview.

I timed this a number of times as well as it dropped in between 5 as well as 6 hrs prior to the red LED began blinking as well as the gadget removed.


  • 2 shells consisted of in the set – dream even more makers did this!
  • Load port gain access to tons much better
  • Great case coil life
  • Really fast fee time
  • Flavour, throat hit as well as heat are place on
  • Incredibly basic to utilize
  • Fantastic guidelines
  • Superb construct top quality
  • Vehicle draw or fire switch turned on – constantly great to have both as the vehicle draw quit working on among my Initial Caliburns!
  • Air movement as well as vehicle draw fire are ideal
  • Extra case consisted of in set
  • Outcome continued to be steady also as battery released
  • Coil gladly managed 50/50 as well as 64%VG e-liquid


  • No USB cable television consisted of – little bit thrifty!
  • Checking out home window is also dark to see e-liquid degree
  • Not suitable with existing Caliburn shells
  • Battery ability has actually not enhanced from the initial.
  • After set has actually been resting or case re-filled you can obtain some e-liquid coming with the mouth piece – take out the case, cover in a cells as well as impact down the mouth piece to clear.

Last Testimonial Judgment

I enjoyed the initial Caliburn – however did obtain irritated with the unpleasant dental filling, slow-moving billing as well as reduced battery ability.

The dental filling as well as billing time have actually been enhanced considerably for the A2 – I simply want the battery ability was higher!

I located I required 2 of the initial Calis to obtain me with the day – so with the battery ability coinciding on the A2 – it coincided tale.

Nevertheless, this is much less of a problem when it bills swiftly – so this is a little bit of a renovation.

This did go down a mark in the “replace if lost or damaged” group as I would typically grab my Innokin Sceptre when heading out as the battery life is a lot longer.

The checking out home window does not truly function as it is also dark as well as it is an embarassment this is not suitable with various other Caliburn shells.

However like the initial any kind of mild groans are discarded because of the large satisfaction of the vape as well as the convenience of usage.

Among the very best Vaping Beginner Kits Around

This is an ideal starter set, simple to load, beautiful to vape as well as also no faffing messing concerning altering coils.

The flavour as well as throat hit are place on – it will certainly offer any kind of brand-new vaper a truly great impression of just how great vaping can be.

Likewise constantly worth having actually one full of nic salt for them times you don’t intend to bring a substantial box mod or you just have the capability to bulge for a fast vape. This will most definitely suffice!

It is a gamble for me which is my much-loved case set of the year – I in fact assume it is a connection in between the Innokin Sceptre as well as the Uwell Caliburn A2.

This is the only set which can match the Sceptre for me!
