The Onnix 20W Pod kit is the latest release and first pod system from Freemax that has 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’s powered by a pretty decent internal 1100mAh capacity battery with 1.5A Type-C fast charging, taking approximately 60 minutes to fully charge the battery.
The pod has an e-liquid capacity of 3.5ml (2ml EU variant), is re-fillable via the silicone rubber side fill port and accepts the OX range of push fit coils. Being both draw activated and push button activated, whichever you prefer to use is switchable via the fire button.
Offering 3 fixed output power levels, each are selectable for the coil type being used, providing 9W, 11W or 13W for the OX DVC 1.0 ohm coil or 16W, 18W or 20W for the OX Mesh 0.5 ohm coil.
I would like to thank the guys at Freemax for sending me the Freemax Onnix 20W pod kit to review. As always this review is completely unbiased and is my honest opinion based on my findings on the Onnix 20W pod kit.

Freemax Onnix 20W Design and Appearance
The dimensions of the Onnix 20W are 109mm tall, 26.2mm wide by 16.2mm deep. It’s constructed out of Steel and Aluminium Alloy and really does appear to be very lightweight, weighing in at only 58.1g. Considering it’s an internal battery pod, you would hardly know you had it in your pocket.
At the top of the Onnix 20W is a deep recess where the pod is housed. Two strong bar magnets, either side of the 2 control pins that connect to the coil, hold the pod in place. These two magnets do a really good job of holding the pod securely in place. So much so, removing the pod does require a strong grasp in order to release the magnetic contact.
The power source of the Onnix 20W is the internal 1100mAh battery, this being a decent capacity to last a whole days vaping. The Type-C charging port is located on the bottom of the Onnix body and is rated at 5V/1.5A so will charge the device pretty quickly (60minutes).
Variable preset power is controlled by clicking the fire button 3 times to select either a low, medium or high wattage output. The power levels depend on the coil that’s fitted and the color changing LED at the bottom of the Onnix 20W housing will indicate which level you have selected.
For the OX 0.5 ohm Mesh coil, 16W = Red, 18W = Blue and 20W = Green. When using the OX DVC 1.0 ohm coil, 9W = Red, 11W = blue and 13W = Green.
A dual airflow slider switch is located on one side of the Onnix body to facilitate RDL and MTL vaping styles. When using the OX Mesh 0.5 ohm coil, the airflow slider control should be set to open to simulate RDL vaping. When using the OX DVC 1.0 ohm coil, the airflow slider control should be set to closed to simulate MTL vaping.
On the other side of the Onnix 20W body is a small fixed airflow opening which provides the right amount of airflow when the slider control is set to closed.
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 4 times. Nice that Freemax have included this option for those wishing to use either method of vaping. This also serves as a locking method to stop inadvertently firing the device when it’s in your pocket or purse.
Branding is limited to the words “Freemax” discreetly printed on the front of the Onnix body, while the words “ONNIX are not so discreetly printed on the reverse side. The Onnix name does take up the whole side of the battery/housing.
The overall surface is covered in a semi matte finish which does feel nice to the touch. At the time of writing, there are 6 different colors available. These are Coral Red, Blue, Grey, Black, Gunmetal and Rose Pink.
Overall it’s a nice looking device but what did really surprise me is how light it feels when you pick it up. The build quality looked good but I do wonder how it would fare if dropped.
Freemax Onnix Pod Design and Appearance
E-liquid capacity of the Onnix pod is 3.5ml (2ml EU variant) and is black semi-opaque in color. The tint is not too dark so the e-liquid is visible through it.
The lower section of the pod is rectangle and has a side filling port, behind a black rubber flap, that fits into the recess of the Onnix. The fill port is pretty big so will allow short stubby tips to be used.
The top section of the pod that remains visible (the mouth piece), when inserted into the Onnix, is a Duckbill shape with a circular 6mm hole in the top.
2 strong bar magnets at the base of the pod located either side of the OX range of push fit replaceable coils do a very good job of securely holding the pod in place.
Inserting the pod is straight-forward, simply line up the pod to the Onnix 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 20W body, the LED on the bottom will light briefly to indicate the pod is fitted and ready for operation.
Freemax Onnix 20W Functionality
The Onnix 20W has limited control over its parameters and as such doesn’t have a dedicated menu button. Instead it utilizes the firing button with the LED color changing indicator to change and identify what’s being set.
Operation of the Onnix 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 alter the wattage in 3 set increments
- Fire button pressed 4 times will switch between Draw Activation or Fire button control
Selecting the 3 set levels of variable wattage is carried out by pressing the fire button 3 times and observing the color of the LED indicator. The 3 set wattage’s will vary depending on the coil type fitted as follows:
- 0.5 ohm coil: 16W = Red light, 18W = Blue light, 20W = Green light
- 1.0 ohm coil: 9W = Red light, 11W = Blue light, 13W = Green light
The Onnix 20W LED will display different colors and sequences to highlight individual functions and safety parameters as follows:
- While Charging: – Red LED cycles between 0% – 35%
- – Blue LED cycles between 36% – 70%
- – Green LED cycles between 71% – 100%
- While Vaping: – LED will illuminate (color determines battery level)
- Low Voltage Protection: – Red LED flashes 15 times
- Short Circuit Protection: – Red LED flashes 3 times
- Over-Time Protection: – White LED flashes 8 times
- Open Circuit Protection: – LED flashes 3 times
- Over Voltage Protection: – Red LED keeps flashing
- Low Resistance (<0.1ohm): – Red LED flashes 3 times
- PCB High Temp: – Red LED flashes 5 times
- Pod Inserted: – White LED flashes once
- Pod Removed: – White LED flashes 3 times
Incorporated on the side of the Onnix battery/body is an adjustable slider to control the airflow between RDL and MTL. This slider does work irrespective of the coil that’s fitted but really should be used as intended. Open when using the 1.0 ohm coil for a MTL draw and closed when using the 0.5 ohm coil for a RDL draw.
Freemax Onnix 20W Kit Performance
Just one word of advice as I learnt the hard way. Always ensure when switching between power levels or selecting the type of draw you want, only do this with the coil filled with e-liquid and primed, or not connected. I stupidly fiddled before I filled the pod with e-liquid and it burnt my coil…lesson learned!
OX Mesh 0.5 ohm Coil (Green Seals) – Pre-installed
The composition of this coil is SS904L Mesh and Tea Fiber Cotton and uses the FM Coiltech 4.0 technology. Freemax recommend using 0-6mg freebase nicotine with this coil. From their documentation, they state that this coil will last for approximately 8 refills before the coil will need to be replaced.
As this coil is recommended for RDL with the airflow slider set to open, I filled the pod with my usual E liquid (6mg freebase Thug Juice).
With the wattage set to the minimum 16W, the flavor kicked in straight away and the vapor produced was very good. Increasing the wattage to 18W and then to 20W did make a slight difference to the flavor and vapor production between the power levels.
Irrespective of the power level I set, I found the coil performed well and the flavor was crisp and fresh. Vapor was good, not excessive but definitely satisfying.
The vaping style using this coil was a restrictive direct to lung vape (RDL), even when using both draw activation and the fire button.
OX DVC 1.0ohm Coil (Blue Seals)
The composition of this coil is a Dual Vertical Coil with Tea Fiber Cotton and uses the FM SaltCoilTech 3.0 technology. Freemax recommend using either Freebase e-liquid between 3-12mg or Nic Salt e-liquid between 20-50mg. From their documentation, they state that this coil will last for approximately 5 refills before the coil will need to be replaced.
As this coil is recommended for MTL with the airflow slider set to closed, I chose to use the same freebase E liquid to get a direct comparison between the two coils.
The flavor and vapor production was as impressive as I found on the 0.5 ohm coil and the draw using this coil was an airy MTL vape. I did adjust the airflow slider to open just to see what would happen, the auto draw wouldn’t operate but did work when using the fire button.
Switching between the 3 power levels again made a slight difference but irrespective of the setting I used I was getting a very satisfying vape experience.
Both coils are good and each gave the respective MTL and RDL draw. Flavor and vapor was good as I would expect now from Freemax. Having cycled 50/50 PG/VG and 75VG through them, neither coil struggled to keep up.
The auto-draw I did find at times a little frustrating but did always perform well. I did tend to use the fire button when vaping more, not because the auto draw didn’t work, just given the choice I preferred the button. I tended to get a more consistent vape when using the fire button.
One observation I found on the auto draw/fire button was, when set to fire button, the auto draw function still worked as well.
The only other point worth mentioning was the visibility of e-liquid in the pod. While the pod is transparent, I did at times struggle to see how much e-liquid was left as the internal design of the pod appears to have additional moldings either side of the chimney. These did obscure gauging an accurate level of e-liquid.
I cannot comment on the longevity of the two coils. What I can say is that I’ve been vaping the Onnix for around 2 weeks, swapping the two coils in and out and they are both are still performing well. I have exceeded the recommended filling times on both coils so that’s a bonus.
Freemax Onnix 20W Battery Performance
The Onnix 20W has an internal 1100mAh battery which did last for a good 8hrs of vaping before I had to re-charge. Obviously this is subjective and depends on your vaping style, the coil type you’re using and the wattage you’ve selected.
A small LED on the bottom edge of the Onnix 20W illuminates when you draw and gives you a visual indication of the remaining battery level. This is achieved by indicating either, Green, Blue or Red as highlighted below:
- Green light indicates 71% – 100% battery power level
- Blue light indicates 36% -70% battery power level
- Red light indicates 0% – 35% battery power level
Good to see that Freemax have included the option of “Pass-Through”, meaning that you can still vape the Onnix Kit while it’s being charged.
How do I Fill the Freemax Onnix Pod?
Simply grasp the pods mouthpiece and pull upwards away from the Onnix 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.
Once removed, you will see the little black silicone rubber flap on the side of the pod, gently pull this flap open.
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 body.
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?
Remove the pod as you would for filling as above.
Because the coils are a push fit type, simply pull the old coil out from the bottom of the pod and replace with a new one.
Note: When removing your old coil, if your pod has e-liquid in it this WILL spill out. To keep this spillage to a minimum, turn the pod upside down and place your finger over the small hole in the mouthpiece. Once the new coil is inserted, no more e-liquid should escape.
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?
Using the supplied charging cable, plug the Type-C USB cable into the charging port on the bottom of the Onnix. Plug the other end into an appropriate power outlet.
When first placed on charge, the LED will illuminate and cycle red in color. Once the charge increases to approx. 36% the LED will change color and cycle blue. As the charging time further increases and reaches approx. 71% the LED will cycle green in color.
Once fully charged, the LED will extinguish indicating the charge cycle has completed.
Charge time from discharged to full charge will take approx. 60 minutes.
As the Onnix 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 20W Pod Kit Price
Expect to pay in the region of £20-£25 for the complete kit. Considering the very reasonable price-tag, coupled with the ability to switch between MTL and RDL vaping styles with the impressive coils, you can’t go far wrong.

Freemax Onnix 20W Pod Kit Summary
Having used the Freemax Onnix 20W kit for a few weeks now, it does tick all the boxes. It doesn’t have variable wattage control but it does have pre-set wattage adjustment so you can tailor your needs. The design and build quality is good. The operation is straight-forward. The flavor and vapor is spot on using either Nic Salts or freebase e-liquids. Draw activation was responsive but as previously mentioned I preferred the fire button.
I enjoyed using the Maxpod when it came out and equally enjoyed using the Onnix. In my opinion, re-fillable pods and replaceable coils is the much better option for me so was glad to see the Onnix didn’t disappoint.
Coil life so far seems really good and no signs of any leaking from the coils.
Would I recommend this? Yes. For those people wishing to have a little adjustment in terms of wattage and not have to buy replaceable pods, this is a good device.
