Freemax Onnix 2 15W Pod Kit Review / An Inspiring MTL Vape Pod

Richard WinterPod Vapes 2 Comments

Welcome to the Onnix 2 15W Pod Kit Review. Firstly though, let me set the scene!

It could only be a few months or so ago that Freemax introduced the Onnix 20W Pod kit which we reviewed here at Vapinghardware.  It was a 20W pod with 3 levels of adjustable power and a unique dual airflow system to cater for Restricted Direct to Lung (RDL) and Mouth To Lung (MTL) vaping styles.

It was powered by an internal 1100mAh capacity battery with 1.5A Type-C fast charging. The pod (3.5ml/2ml) was re-fillable and accepted the OX DVC range of push fit coils. Also the pod was both draw activated and push button activated.

Overall, we really licked the Onnix pod kit and as always, the performance and flavor were really good. Being able to switch between RDL and MTL with the selected coils and airflow was spot on. Tweaking the adjustable power levels to fine tune your vape and the OX range of coils for the Onnix were a dream to vape on.

So……… imagine our surprise when we received the Onnix 2 so shortly after the Onnix (1).

Anyway, moving forward, let’s get stuck into the review.

Onnic 2 Pod Kit Plus Coils

The Onnix 2 is a 15W pod specifically aimed as a MTL Pod. Although the Onnix 2 is specified as a 7W-15W pod, the wattage is fixed and relies on the automatic coil recognition to set the wattage depending on which coil you are using (Auto Wattage).

Variable airflow is no longer present as it’s a MTL pod device. Two small air holes are visible, one each side of the battery body to facilitate the MTL draw.

The Onnix 2 is both Draw activated and Fire button activated, either being selectable by clicking the fire button 3 times in quick succession.

Surprisingly enough, the internal battery capacity has reduced from 1100mAh down to 900mAh. I’m guessing that’s due to the reduction in the overall size of the Onnix 2 and being a lower wattage pod specifically for MTL use.

The pod has changed, still continuing with the duckbill shape, still re-fillable via the side filling port and accepts the range of OX DVC coils. E-liquid capacity is limited to 2ml only now. Because the pod itself is a slightly different shape and design, they are not interchangeable between the two Onnix versions.

Cosmetically the two look very different. The Onnix 2 looks cleaner, sleeker and a lot more modern. Gone is the sharp oblong look, replaced with a very tactile and comfortable to hold battery body. The overall finish looks to be of a much higher standard.

Overall and my first impressions are I like it, I like it a lot.

I would like to thank the guys at Freemax for sending me the Freemax Onnix 2 15W pod kit to review. As always this review is completely unbiased and is my honest opinion based on my findings on the Onnix 2 15W pod kit.

For all you sharp eyed folks out there, I’ve missed off the charging cable from the image. I was going to make an excuse and say that my dog had run off with it and chewed it up! Or even better, aliens had taken it away during the night.

Sadly no one else is to blame other than me. It wasn’t till I completed the photos and saw that I didn’t include it in the piccy that it was too late. My bad!

Freemax Onnix 2 15W Design and Appearance

The dimensions of the Onnix 2 are 109mm tall, 24.4mm wide by 15.3mm deep. It’s constructed out of Aluminium Alloy and weighs in at only 47.6g. Considering it’s extremely lightweight, there is a superior quality feel to it.

Freemax Onnix 2 Top View

At the top of the Onnix 2 there is a deep recess where the pod is housed. Two bar magnets, either side of the 2 spring loaded gold plated control pins that connect to the coil, hold the pod securely in place. When the pod is inserted into the Onnix 2 battery, the blue “Working Light” will illuminate briefly.

Freemax Onnix 2 Bottom View

Powering the Onnix 2 is achieved by the internal 900mAh battery and charging the battery is carried out via the Type-C charging port located on the bottom of the Onnix 2 body. The charge port is rated at 5V/1.5A so will charge the device pretty quickly (60minutes).

With regards to the power output, the specification of the Onnix 2 is 7W-15W. There is no variable wattage adjustment per say, it’s auto set by the coil type that’s fitted. Smart coil recognition will detect the resistance of the coil and set the wattage accordingly for optimum performance.

What I’m not clear on and couldn’t find any information on, is exactly what the set wattage is for each coil type. I can only assume it will be on the higher side of the minimum and maximum wattage range for the particular coil.

Vaping the device can be either Draw Activated or Fire Button Activated, irrespective of the coil type fitted. Switching between the two is carried out by clicking the fire button 3 times. By selecting draw activation, the fire button will be locked to stop inadvertently firing the device when it’s in your pocket or purse.

Two small airflow holes, one on each side edge of the Onnix 2 body a quarter way down from the top, are sufficient to provide the perfect MTL draw. During my time vaping the Onnix 2, I did find at times placing my finger over one of the side airflow holes gave me a more restricted draw.

Branding has been toned down from the Onnix 20W, gone is the massive ONNIX printing on the side of the battery. Instead we have the words “FreeMax” discreetly printed on the front of the Onnix 2 body, while the words “ONNIX 2” are nicely printed on the reverse side. In my opinion this makes the whole device look a lot more professional and smarter.

Freemax Onnix 2 Button View

A raised circular fire button which is concave allows your thumb to sit nicely in the button (very tactile). It’s NOT a “clicky” button, only requiring minimal pressure to activate. It IS responsive and there is NO button rattle. Locking the fire button if you’re carrying it around in a pocket or purse would be recommended.

Two full length panels are inlaid on the Onnix 2 body on both sides which carry the colored design. Both fit very well with no sharp edges and are shiny. Freemax call the finish on the side panels “A new generation of UV transfer technology” making it highly reflective and anti-fingerprint and anti-scratchproof.

Freemax Onnix 2 Display Lights

Below the words “FreeMax” on the front panel are 3 invisible white lights which indicate the status of the battery and a 4th blue light (working light). You cannot feel them or see them until the Onnix 2 is powered and being used. They are fitted beneath the inlay panel and when visible are quite bright and really do look good.

The side edges of the Onnix 2 are colored in a metallic finish while the two inlay panels have the colored design. There are 6 different colors available. These are Red, Blue, Grey, Black, Green and Pink.

Overall it’s a really nice looking pod body, looks smart, feels nice in the hand, lightweight, discrete, simple to use and well built. I found it reminiscent of the Freemax Max Pod we reviewed a couple of years ago.

Freemax Onnix 2 Pod Design and Appearance

The Onnix 2 pod has an e-liquid capacity of 2ml (no other sizes are available) and is black semi-opaque in color. The tint is very minimal so the e-liquid is clearly visible through it. Too many manufacturers use too dark a tint making it virtually impossible to gauge how much e-liquid is left in the pod. NOT the case with this one!

Because the pod on the Onnix 2 is a slightly different shape and size from the Onnix, the two pods are NOT interchangeable. BUT, the coils ARE.

Freemax Onnix 2 Rubber Fill Port Flap

The lower section of the pod is rectangular and has a side filling port, behind a black silicone rubber plug. This fill plug flap has the words “FreeMax” on it and just below the letter “a” is a little arrow with donates the side that should be lifted up to gain access to the fill hole. There is also a small fingernail slot below the arrow for those of us that have nails.

Freemax Onnix 2 Fill Port Open

Its fill port hole is not the usual oval shape, more a droplet shape, but is still big enough to allow needle tip and short stubby tips to be used.

Either side of the coil opening are two flush sitting bar magnets that locate with the magnets in the Onnix 2 body/battery when the pod is inserted.

The top section of the pod that remains visible (the mouth piece), when inserted into the Onnix 2, is a Duckbill shape with a circular 6mm hole in the top. Perfect for MTL vaping.

The pod accepts the OX range of push fit replaceable coils. There are current 4 different coil types but only the OX DVC coils can be used with the Onnix 2 because of the limited top end wattage (15W).

Inserting the pod is straight-forward, simply line up the pod to the Onnix 2 opening and it will slide into the recess and be locked in place by the magnets. The pod is bi-directional so can be fitted either way round. Removing the pod is carried out by applying pressure to the mouthpiece and pulling upwards.

When the pod is attached to the Onnix 2 body, the blue (working light) LED on the bottom of the Onnix 2 front panel will light briefly to indicate the pod is fitted and ready for operation.

Freemax Onnix 2 15W Functionality

The Onnix 2 15W pod kit has been kept really simple and as such has very limited control. There is no dedicated menu button and no screen display. It really is a Plug and Play pod.

Operation of the Onnix 2 is carried out using a sequence of clicks of the firing button as follows:

  • Fire button pressed 5 times turns the device on or off
  • Fire button pressed 3 times will switch between Draw Activation or Fire Button control

When the auto draw activation is set, the fire button is locked and will not fire. Perfect if it’s being carried in a purse or pocket.

What the Onnix 2 does have are 3 hidden sequential white lights and a blue (working light) embedded below the front panel.

The Onnix 2 LED’s will display a different sequence to highlight individual functions and safety parameters as follows:

  • While Charging:                      One white light illuminated 0% – 35% of charge
  •             “                                   Two white lights illuminated 36% – 70% of charge
  •             “                                   Three white lights illuminated 71% – 100% of charge
  • While Vaping:                          Blue working light illuminates then white light(s) illuminate *
  • Low Voltage Protection:          All white lights flash 15 times
  • Short Circuit Protection:          White light flashes 3 times
  • Over-Time Protection:             Blue light flashes 8 times
  • Open Circuit Protection:          Blue light flashes 3 times
  • Over Voltage Protection:         All lights keep flashing
  • PCB High Temp:                      All light flash 5 times
  • Pod Inserted:                           Blue light flashes once
  • Pod Removed:                         Blue light flashes 3 times
  • Button Activate Lock/Unlock   Blue light flashes 4 times

* Once the blue working light extinguishes, either one, two or three white lights will illuminate briefly indicating the remaining level of charge.

Freemax Onnix 2 15W Pod Kit Performance

The composition of both coils is Dual Vertical Coil with Tea Fibre Cotton and uses the FM SaltCoilTech 3.0 technology.

OX DVC 0.8ohm Coil

Freemax recommend using either Freebase e-liquid between 3-9mg or Nic Salt e-liquid between 20-35mg. The coil wattage range is specified between 12W-15W.

Freemax OX DVC 0.8 Ohm Coil

After doing all the usual priming and leaving to sit for 15 minutes, I was ready to go!

My e-liquid stocks were running low so I was limited to using my 6mg freebase Mango Ice (I’ve always got plenty of that!).

After a couple of draws the flavor really kicked in and vapor production was pretty decent. I was pleasantly surprised as the taste of the Mango seemed to be quite prominent and very sweet.

Trying both the fire button and auto draw worked faultless, both gave similar results. Overall, a really nice vape giving quite an airy MTL draw. The power level certainly seems to give good results.

With this coil I did find myself at times placing a finger over one of the air holes to restrict the draw a little.

OX DVC 1.0ohm Coil

Freemax OX DVC 1.0 Ohm Coil

Freemax recommend using either Freebase e-liquid between 6-12mg or Nic Salt e-liquid between 30-50mg. The coil wattage range is specified between 9W-13W.

Swapping the coil out for the 1.0ohm coil wasn’t a problem and I didn’t loose any e-liquid.

Very similar to the 0.8ohm coil in terms of flavor and vapor but the draw seemed to be a little tighter (more restrictive). Also I feel the vape didn’t appear to be as warm.

I will be honest and say I couldn’t tell if the power level had changed from the previous coil.

Definitely another impressive coil. I’ve been vaping on this coil for well over a week now with no loss of flavor.

Coil/Performance Summary

Both coils are equally as impressive and each gave really very good flavor and vapor. For fear of repeating myself, Freemax coils across all their platforms really are some of the best ever.

Having cycled 50/50 PG/VG and 75VG through them, neither coil struggled to keep up.

The auto-draw didn’t falter, working every time and didn’t seem to be any less of a hit when comparing it to using the fire button.

Freemax Onnix 2 15W Battery Performance

The Onnix 2 15W pod kit has an internal 900mAh battery which did last for a good 12hrs of vaping before I had to re-charge. Obviously this is subjective and depends on your vaping style and the coil type you’re using.

The 3 small white LED’s towards the bottom of the front panel of the Onnix 2 illuminate after you’ve drawn on the pod giving you a visual indication of the remaining battery level. This is achieved by the sequence of the 3 white lights as highlighted below:

  • Three white lights indicates 71% – 100% battery power level
  • Two white lights indicates 36% -70% battery power level
  • One white light indicates 0% – 35% battery power level

While this is a handy feature, giving you a visible status of the remaining battery usage, don’t take these figures as being too accurate.

Good to see that Freemax have included the option of “Pass-Through”, meaning that you can still vape the Onnix 2 Kit while it’s being charged.

How do I Fill the Freemax Onnix 2 Pod?

Simply grasp the pods mouthpiece and pull upwards away from the Onnix 2 body. Because the pod is a very secure fit, slightly prize the pod to one side releasing one of the bar magnets then pull the pod out.

Freemax Onnix 2 Pod Ready For Filling

Once removed, you will see the little black silicone rubber flap on the side of the pod with the words “FreeMax” written on it. Below the letter “A” is a small arrow which donates which side of the flap opens. Also you will see a very small fingernail channel to assist when opening the flap. Gently pull this flap open.

Once open, the silicone rubber flap will remain attached to the pod so it won’t get misplaced. The fill port is now accessible. It’s not the largest filling port I’ve seen but adequate enough to take either a needle tip or a short stubby tip e-liquid bottle.

Freemax Onnix 2 Pod Filling With Juice

Tilt the pod on its side to make filling easier. Place your e-liquid bottle tip into this opening and squeeze the bottle. You will see the e liquid start to fill in the pod.

Once complete, replace the black silicone rubber flap and re-insert the pod back into the Onnix 2 body.

The Onnix 2 pod is uni-directional so can be fitted either way round.

Quick Tip: If you are filling the pod for the first time, drip a few drops of e liquid onto the wick of the coil first. Push the coil into the pod then fill the pod and leave to stand for approx. 10-15 minutes before you start to vape. This will help saturate the wick fully in e-liquid and help prolong the life of your coil.

How do I Change the Coil in the Freemax Onnix 2 Pod?

Freemax Onnix 2 Coil Out Of Pod
Freemax Onnix 2 Coil In Pod

Remove the pod from the Onnix 2 body/battery as we described in the How to Fill section above.

Because the OX range of coils are of a push fit type, simply pull the old coil out from the bottom of the pod and replace with a new one.

If the pod has e-liquid in it while you’re removing the coil, e-liquid will spill from the pod. The best method to avoid this or to keep e-liquid spillage to a minimum is to place your finger tightly over the opening of the duckbill mouth piece and then remove the coil.

Replace with a new coil while still holding your finger over the opening in the mouth piece. Once the coil has been inserted into the pod, take your finger off the opening. Hopefully none, or very little e-liquid will be spilt.

As always, when replacing a new coil, follow the procedure as outlined in the quick tip above under ‘filling’.

How do I Charge the Freemax Onnix 2?

Using the supplied charging cable, plug the Type-C USB cable into the charging port on the bottom of the Onnix 2. Plug the other end into an appropriate power outlet.

Charging the Onnix 2 Pod Kit

When first placed on charge, one white light will illuminate and remain static. Once the charge increases to approx. 36% the second white light will illuminate and both will remain static. As the charging time further increases and reaches approx. 71% the third white light will illuminate and all three will remain on.

Once fully charged, the three white lights will extinguish indicating the charge cycle has completed.

Charge time from discharged to full charge will take approx. 60 minutes.

As the Onnix 2 does have pass-through, you can vape while it’s on charge.

Always observe safe charging practices i.e. always charge on a non-flammable surface and NEVER leave your device unattended whilst charging.

Freemax Onnix 2 15W Pod Kit Price

Expect to pay around the £20 mark for the pod kit. It’s one of the best MTL pod kits I’ve come across for simplicity and performance.

Freemax Onnix 2 15W Pod Kit Summary

Having used the Freemax Onnix 2 15W pod kit for a couple of weeks now, I’m very impressed.

It doesn’t have all the usual stuff to fiddle with such as variable wattage control or airflow like the original Onnix did, but to be honest, this is what I loved about it. Sometimes it’s a pleasure to not have to think about anything, pick a vape up and toot away. This certainly was a pleasure.

The Onnix 2 is a really decent, hassle free, well designed and built pod kit. In terms of aesthetics, it looks really good. The flavor from the coils is always going to be really good because that’s what Freemax do….really good coils.

Draw Activation was always responsive, perfect to just pick up and go. Coil life so far seems really good and no signs of any leaking from the coils.

Would I recommend this? Yes definitely. Would I buy another one? Yes. Freemax have produced another winner and I will say I like this more than the original Onnix and I liked that one too.

Hope you enjoyed this review on the Onnix 2 15W pod kit and found it useful. If you have any questions or feedback, please feel free to leave us a comment below.

    1. Hi Clayton,
      Unfortunately we’ve not come across this problem before. The over-voltage protection is there to safe guard the battery from overcharging or applying too much power to the coil/pod. I can only suggest leaving the pod for a day or two so the battery voltage reduces and see if it will work with that reduced charge voltage.
      Failing that, try contacting Freemax directly and see if they will provide you with a replacement.
