SMOK TF-RTA G2 & G4

TF-RTA G2 & G4

Never a Company to allow the grass to grow under its feet SMOK’s innovative design team have produced yet another excellent example of what vapers are seeking in a revolutionary RTA, that surpasses previous models and raises the benchmark yet another notch for others to follow suit.

Their latest edition the TF-RTA comes in not one but two versions, the G2 and G4. The G2 houses a large dual post velocity style deck with an increase in its overall surface area by up to 30% compared with the former TF-RTA deck, to make life just that little bit easier for building on- especially when using some of the more sophisticated and artistic low sub ohm coil types available today.

And the G4 as its title suggests is also a large quad coil deck designed with the intention of creating immense vapour as you would normally expect to experience when using a quality RDA setup.

The G2 arrived from SMOK with Fused Clapton Kanthal and Nichrome wire coils at a resistance value of 0.4Ωs while the G4 houses a quad coil set up with a resistance value of 0.14Ωs. Please, check the pre installed resistances for each version on a reputable Ohm’s Meter before use as these are clearly ultra low resistances.

Apparently both these tanks have been manufactured for the very experienced vaper as opposed to the novice. So, at this point in the review, I would strongly suggest that you have a thorough understanding of battery safety and ohm’s law if you’re considering purchasing either of these Rebuildable Tank Atomisers and you own a regulated device (preferably) that can support both of them.

You can, of course, remove the preinstalled coils and replace them with a higher resistance value  of your choice if you feel the current setups are too low for you. Also, SMOK provides TF-RTA Clapton wire separately in 0.4Ωs and 0.14Ωs respectively.

SMOK’s engineers are always seeking to introduce revolutionary ways to improve upon past models and to that end, they have added a new airflow design into each version, plus a hidden sealing ring and innovative juice flow control system to significantly reduce the potential for leaking.

Let’s take a look at what’s in the box and a full rundown of the specs for each one.

Operation & Performance

For the purpose of conducting this review, I have used a selection of two different E-Liquids with varying PG/VG combinations from Electric Lotus Pour House and the supplied coils from SMOK plus two 0.6 ohms prebuilt Helix 28G Kanthal A-1 Clapton coils from Tradition Vapes on the G2 version only so far.

The quality of these coils as I have said before is remarkable with an excellent choice on offer to you and even more in the pipeline.

Cotton of choice for me personally is the MUJI Japanese Organic cotton as I seem to get a slightly cleaner flavour from it.

REACH compliant

If you intend to use this range of E-Liquids, please make sure they meet the current requirements set out by your countries regulatory bodies.
For EU countries, more information on this subject can be found here along with REACH’s partner agencies from around the globe.

E-Liquids may contain Diacetyl (DA) and Acetyl Propionyl (AP) or other carcinogenic ingredients or disease-causing substances, so please be aware of this and seek medical advice before using any of the products used in my reviews.

People can suffer from allergies to chemicals that may be present in the makeup of particular types of E-liquids or produced in their vapour. People can become sensitive to or even allergic to Nickel or Titanium used in Temperature Controlled designed coils. Again, please be aware of this and seek medical advice before using any of the products used in my reviews. Also, check with your E-liquid supplier or the equipment manufacturers directly before purchase and use.

You might also find this range of calculators provided by Steam Engine particularly useful, so thank you to Lars for allowing me to include them in my reviews. These calculators are currently under development, and the information that they contain may change at any time without notice. Please read the How It Works section for a more in-depth understanding. And never leave your device charging unattended, make sure you are using the recommended battery for your device, and always remember, SAFETY FIRST.

 

For newcomers or inexperienced vapers to building your own coils you can find some excellent tutorials on YouTube so I would suggest looking at these initially to gain as much knowledge as possible before attempting a build by yourself.

Additionally, you can seek further advice from your local vape store first or from more experienced vapers to be found in the chat rooms. There’s plenty of help out there if you look for it, and never be afraid to ask for help.

I can personally recommend purchasing everything you will need to start making your own builds from Coil Master . I’ve been a big fan of their products and use them all the time. Check out the link below, or contact your local B&M store for more information.

And with both, the G2 and G4 SMOK has already included the first build for you! My suggestion would be to begin with the velocity style G2 first and move onto the G4 when you have gained a sufficient amount of experience. Don’t rush it just enjoy it.

Operation

SMOK have thoughtfully, as I have just mentioned, pre installed coils already onto both the G2 and G4 off base decks for you. So you will only need to add some Organic Cotton and apply your preferred E-Liquid to both, fill the tank from the top remembering to close off the adjustable juice flow control while filling up your tank.

You will need to open and set it again after filling to obtain the best results for wicking depending on the PG/VG balance of your liquid and the output voltage being applied to the coils.

With the correct balance set between the Juice flow control and the Air flow control these new RTA’s produce some incredibly dense clouds and some mighty flavoursome vapes.

I’ve used the G4 well above 100 watts without any sign of a dry hit, and don’t forget; we are using an RTA here not an RDA!

Try not to add in too much cotton to your builds which should help to minimise any potential wicking issues at the higher temperatures. And as SMOK have suggested in their user manual, cut the cotton at an angle allowing just enough length to fit into the juice wells on each side of the coils.

With the G4, you will notice that one juice well is shared on both sides between two coils so keep the cotton fluffy and not too thick allowing it to pass through the coil smoothly as a guide.

Check your resistances and make sure you are using a device (preferably a regulated device) that can support this type of low Sub Ohm Vaping.

Look for signs of any hotspots that may require adjusting with ceramic tweezers on each of the attached coils. Pulse them and look for an even glow across the surface area of each one and tweak them if necessary.

Check for shorts with your Ohm’s metre before adding organic cotton and your juice to the coils. I forgot to do this myself! These things can and do happen especially if you get interrupted!!!

If all these checks are good, then you should now ready to fire the attached device and experience improved flavour and vapour production compared to past models from SMOK. This is truly a step up on the already popular TFV4.

The Tank

The tank closely resembles that of the previous TFV4 holding up to 4.5ml of liquid with the swivel top fill cap but that’s where the similarity ends, and the swivel cap has been improved upon too.

The original 510 drip tip with airflow inlets for slipstreaming has been replaced with an outer metal casing and a glass inner to help reduce heat buildup in the mouthpiece, and an entirely new airflow design has been incorporated into the latest tank overall.

The juice flow control is smooth to operate and functions very well giving you the opportunity to set the amount required at any given time. This is useful if you chain vape for example as you can increase the volume supplied to the coil reducing the risk of that dreaded dry hit.

With an improved anti-leak seal added and the ability to fully close off the juice flow, leaks should start to become a thing of the past.

You now have the capacity to switch decks thanks to a cleverly modified base unit creating more latitude to add in future deck designs further down the line, without having to purchase a whole new body as well.

Here’s a quick rundown for you of the G2 and G4 replaceable decks

The G2 Deck

Apart from the increased space thanks to its 16mm diameter circumference the inclusion of an off base velocity style deck with large posts makes the G2 a joy to behold and to work with (love this design).

The deck is fully removable from the base as I mentioned. All you have to do is unscrew it carefully so as not to damage the attached coils if you have them in place.

The threading is silky smooth but short so take care not to drop it when you try this for the first time or be seated like me so it drops straight into your lap, un-wicked and coated with liquid, fortunately!

Added to this they have two large bore air holes placed directly beneath each of the coils, and there is a centre airflow system situated between the posts providing additional air from the side to the coils.

The flavour you will experience from this even with a single coil is truly impressive and it still produces some pretty good vapour around the 60w-80w mark without dry hitting.

So if a velocity style deck is what you prefer to build on, then the G2 should be at the top of the agenda when you visit a local SMOK stockiest to check it out for yourself.

The G4 Deck

The G4 deck with a quad coil setup produces very dense vapour clouds as you would expect but with the inclusion of the juice control and improved airflow, I found the vape remained moist without any unexpected dry hits up to my maximum of 130watts.

The tank does start to get hot and the juice evaporates at a rapid rate of knots, but the clouds it produces are of competition standard. The 510 drip tip remains far cooler than I had expected it to above 100w allowing me to complete successive draws before it started to become uncomfortable.

Given the amount of space above the coils the G4’s Quad coil setup helps to close the gap nicely between a two coil drippers performance producing a surprisingly flavoursome and intense vaping experience allowing me to distinguish between the individual flavour notes more easily than other RTA’s currently in my possession.

That s not taking anything away from the G2 when set to lower wattages (50w-80w) but at the higher output levels (above 80w) you notice the flavour of the G2 compared to the G4 start to fall off.

This is where the additional surface area of a quad coil setup starts to make a difference. So, if you like a much warmer vape while maintaining that much fuller flavour and denser clouds above 80w the G4 might be better suited to your needs.

Building on this deck is a little trickier at first than the G2 due to the positioning of the terminals. I strongly recommend allowing enough wire at each end to start with until you get a feel for the amount you will require on future builds and check each one to make sure it is secure and not touching the casing at any point.

Conclusion

Attention to detail is paramount when introducing a new product onto the market, especially when you consider the sheer amount of options available to you from so many different manufacturers.

So adding two new products in the form of an RTA that can match the performance only to be found until now with a dripper, is a huge step up indeed.

Think about it, vaping well above 100 watts on an RTA with no sign of a dry hit in sight.

Flavour production was almost equal to that of a well constructed and manufactured RDA, and I have a few of these in my possession with three years vaping experience behind me to be able to tell the difference by now.

The ability to finally take a tank to work with you and experience a warm, intense flavoursome vape without the added hassle involved of dripping on your lunch break.

The G2 & G4 models from SMOK appear to have the answer to these problems finally taken care of. The inclusion finally of juice control flow minimises both flooding and dry hits but was a little loose for my liking so could be a bit tighter in my opinion. And the hidden sealing rings reducing the possibility of leaks, not to mention the future option of swappable decks means you are going to have to take notice of these impressive RTA’s.

SMOK have made improvements to the 510 connector on both of these two new models allowing for flush mounting on all of the devices I have tried them on to date which was not always the case with the TFV4.

Remember to take the time to experiment with your cotton to get the best possible results from each of these two RTA’s. I’ve found it’s better not to have excessive amounts of cotton, and just to allow enough overhang to enter into the juice wells.

Also, get yourself familiar with the airflow and juice control options to avoid flooding and dry hits. Once you have mastered these three key elements, you are going to fully appreciate the modifications that have been included into both of these tanks. The first true RDA experience in an RTA? You decide!

As I have only had these for a week, I’ll update you in this section with a fuller breakdown on the performance of each one, but for now, I have to say I’m suitably impressed by my initial assessment and the performance of both designs. The machining is of a very high standard too.

RRP around £24.00-$30.00
