Without a doubt the Vaporesso GEN S kit is for the DTL vaper. Moreover the dual 18650 battery mod with its reported output of 220W, coupled with the NRG S tank seems to tick all the right boxes for DTL vaping. But is the NRG S tank without problems? Hows the battery performance with the allegedly flavour improving Pulse mode? Lets find out and delve deeper into this review of the Vaporesso GEN S kit.

Box Contents

Below is a quick breakdown of what you may expect to see included with the Vaporesso GEN S kit.

Typical of the packaging style of Vaporesso, the colour and imagery reflects the chosen colour option for the Vaporesso GEN S Kit. Moreover the laminated image fills most of the front. While the sides show key elements of the Vaporesso GEN S in icon form. Additionally on the back is the specifications, contents, governmental compliance logos, health warnings and authenticity checker.

Removing the lid reveals the Vaporesso GEN S with the NRG S tank and GT 0.18Ω mesh coil pre-fitted, sat within its plastic inlay. While underneath the inlay are the spare glass, spare o-rings, Micro Type B USB cable, GT4 0.15Ω Mesh coil and user manual.

Build quality

Without a doubt the Vaporesso GEN S is a smart looking and lightweight kit. Moreover the dimpled rubber coated side panels grip very well. Additionally the panels colour gradient matches the rest of the mod.

While the Vaporesso GEN S with a full tank of e-liquid and two 18650 batteries weighs in at 269g. The mod is reassuringly sturdy in the hand and feels like it can hold up well to daily use.

However while the battery doors fit perfectly with no movement, the recess on the mod for removing the battery door needs to be a little wider.

Despite the Micro Type B USB port being cleanly cut. Many will be disappointed with the lack of a USB-C connector.

Naturally as the mod is formed from one larger section the fascia is nice and clean. Although the placement of the menu button is a tad too close to the up and down buttons. Consequentially when changing the wattage output the menu button can be accidentally pressed. Nonetheless all the buttons are audible and responsive.

Furthermore the LCD screen is easy to read with its crisp display. However like the other GEN mods available, the layout of the screen is a little cramped. Especially the smaller readouts that may be difficult to read for those with eye sight issues.

510 Connector

Without a doubt the GEN S mod happily seats the 30mm NRG S tank with no spill over, making it perfect for most tanks on the market. Importantly the threading is well cut and silky smooth, with the 510 centre pin offering a good level of stiffness. Which gives some confidence in its long term use. Furthermore the centre pin appears to have a throw of approximately 2-3mm, which is good to see.

NRG S Tank

Visually the Vaporesso NRG S tank matches the colour of the mod well. But not perfectly. Furthermore the cleanly cut exterior features plenty of knurling to aid adjustments and removal.

But there is a slight issue with the top cap. Moreover the removable top cap cover is undone by turning the cap counter clockwise. However when you tighten the tank together after replacing the coil, the top cap begins to become unscrewed and becomes needlessly bothersome.

Nonetheless the well cut threading on the top cap and base, threads on and off smoothly. While the airflow control ring with its cleanly cut airflow inlet glides effortlessly, yet remains resolute in its position.


Dimensionally the Vaporesso GEN S with the NRG S tank fitted stands 145.5mm tall from the base of the mod to the top of the drip tip. Furthermore the GEN S mod is 30mm wide and 53mm deep from front to back.


Turning on the Vaporesso GEN S is via the customary 5 clicks of the fire button. Additionally pressing the fire button quickly three times locks the GEN S. Preventing the settings from being accidentally changed. To unlock repeat the process.

Naturally holding the additional menu button opens the settings menu. Allowing the user to change the vape mode of the GEN S. However to enter and store the changes the menu button is used instead of the fire button.


As previously mentioned access to the various modes is via holding the menu button. Once inside the settings menu, you have access to the various vape modes available on the Vaporesso GEN S. Additionally there are no restrictions on the selectable power outputs such as the wattage mode.

Pulse Mode – Default

While designed to optimise the vape experience by pulsating the power output. Thus in theory, maintaining the temperature of the vape for a perfect experience. However the effect on the vape is hardly noticeable.

Power Eco

Designed to automatically kick in when the battery drops below 40% and unable to support the current power output. While this does improve battery life slightly, depending on coil it is at a cost to flavour.

Smart TC

Without a doubt temperature control modes are like the Marmite of the vaping world, you either love it or don’t. Nonetheless when a Stainless Steel, Titanium or Nickel coil is detected. The Vaporesso GEN S can be set to automatically enter the Temperature Control mode.

DIY Mode

Within the DIY Mode on the Vaporesso GEN S are the more common vape modes.

VW – Variable Wattage Soft, Normal, High

From within the VW mode the initial power is settable. For instance if you want the vape to produce a quicker and warmer start and then default back to the set wattage, you would select the H mode. Regardless of the selected option, the wattage mode remains adjustable in 0.5 watt increments.

VV – Variable Voltage

Similar in methodology of the VW mode, whereas wattage is used in controlling the output. Instead voltage is used as the method of controlling the power output and there is no soft, normal, or high options.

CCW – Custom Curve of Wattage

Similar in notion to the soft, normal, or high option within the wattage mode. However with the use of time, a tailored adjustment of the wattage can be made. Moreover each wattage bar within the curve lasts for 0.5s and the wattage for each is user determined. Allowing for a more tailored experience. For example if so desired you could have the Vaporesso GEN S turn on and off completely ever other second. Additionally the mod could produce a more smooth linear curve tailored perfectly to the coil and flavour profile of the e-liquid.


A form of protected mech mod mode. Moreover the coil receives the power output from the remaining battery voltage.

Super Player Mode

Not for the inexperienced vaper. Moreover the Super Player Mode opens the allowable resistance range for coils. Moreover the resistance range of 0.03Ω to 5Ω is for use with RTA, or RDA tanks fitted to the Vaporesso GEN S.

System Set

Within the system set menu on the Vaporesso GEN S are some expected options such as screen brightness, screen orientation and more. Additionally within the system set option is the rather oddly located Smart Variable Wattage mode.

Smart VW – Smart Variable Wattage

Without a doubt the Smart VW mode appears to produce a slightly warmer vape regardless of setting.

Battery Use

Note* The lengthy time for charging is due to cable used while photographing.

While the Vaporesso GEN S utilises dual 18650 batteries, battery economy is good and as expected with the enclosed coils. However battery economy is improved with the Pulse mode turned off. Moreover I suspect the continuous pulsing of the power output uses more power than one would expect. Presumably due to the continuous ramping up and down of the power output rather than a straightforward pull of current.

Importantly if used at higher wattages, ensure the batteries are suitable for the amperage.

Specified with a charging rate of 5V 2.5A via the Micro Type B USB cable connector. The Vaporesso GEN S would charge at 5.2V 2.25A, which isn’t too far off. However I will always highly recommend not to a mod for charging, regardless of the manufacturer. Importantly a dedicated battery charger from a trusted manufacturer will always be the safer option.

Nonetheless a nice feature of the Vaporesso GEN S is the estimated recharging time for each individual battery. Which is displayed below the animated icons with the current battery levels shown in a percentage readout. Additionally if the need arises the GEN S will stop charging if you require a quick vape. Then continues to charge again after the fire button is released.


Unlike the Vaporesso GTX tanks, the NRG S features a slide back method of refilling which is great to see. Moreover the top cap slides effortlessly, yet remains steadfast when in the closed position. However as typically with most slide back top caps, the drip tip can hinder refilling with wider e-liquid bottles.


While the airflow design of the Vaporesso NRG S tank is a little noisy and more tailored to DTL vaping. Nonetheless the fully adjustable airflow can be closed down if required, providing a tighter draw. Regardless of the smooth moving airflow control rings position, the vape remains smooth with no turbulence.

Coil Replacement

Undoubtedly changing the coils on the Vaporesso NRG S tank is an easy task. However as the coil screws into the base it is not the cleanest. Moreover you need to grip the soaked coil in order to replace it. However the longer chimney on the full size NRG S allows for the swapping of coils with a good amount of e-liquid remaining.

A point of note, when the coils are nearly finished they begin to leak into the airflow control ring, spilling out when the tank is tilted when vaping or when changing batteries. Which is not good.

Nonetheless with the old coil removed, prime the new coil by placing a little e-liquid down into the coil, and a drop onto each wicking hole. Now pop the new coil into the pod and refill if need be. Additionally leave the coil to sit for a while to ensure it becomes suitably saturated. Typically I like to leave it 10 – 15 minutes, then vape.

GT 0.18Ω Mesh Coil 50W-85W

Without a doubt wicking on the GT 0.18Ω coils is good and easily handles chain vaping. Furthermore flavour from these coils are great, with a wide range of tonality. Moreover Lemon Meringue comes out beautifully. But fruits are sublime, with Peach flavoured e-liquid coming through extremely well. All while vaping around 60W.

GT4 0.15Ω Mesh Coil 50W-75W

With little break-in time, the GT4 coil wicks and vapes like a champ from the get go. Moreover cream and custard based e-liquids are better on the GT4 than the GT. Furthermore low and high end fruits come through well. Especially Mango flavoured e-liquids. However after just 3 refills the coil suffered from continuous dry burns and was completely unusable.

GT8 0.15Ω Coil 50W-110W

Vaporesso sent along with the GEN S Kit a pack of GT8 0.15 coils for testing. But something is not right with the GT8 coils supplied. Despite looking like single wire coils they are labelled as Clapton. Additionally the coil is rated between 50-110W, yet on testing two coils they began to dry burn from 65W. Nonetheless the coils are flavoursome from the start. However the wicking isn’t that great for long pulls or chain vaping. Nonetheless the coil is best suited to 55-60W with fruits and cola based e-liquids.

Chipset and Protection

Powered by an unspecified chipset, the Vaporesso GEN S mod offers the following levels of protection.

  • Overtime Protection 10s – Protects against continued accidental firing.
  • Overheat Protection – Protects the internal PCBA of the mod.
  • No Load Protection – Prevents firing when no tank if fitted.
  • Short-circuit protection – A form of over current protection.
  • Low Battery Protection – Prevents the battery levels dropping to a point of no return.
  • USB Input Protection – Prevents high voltage damage by stopping the charging process.

However it is odd that there is no mention of either low or high resistance protection, nor over discharge or charging protection.

Fundamentally there are two niggles with the NRG S tank and one with the mod. Firstly when the coils are nearly finished they begin to leak or seep into the airflow control. Consequentially when you change batteries in the mod or tilt the tank while vaping, e-liquid leaks out of the mod. Secondly is the top cap cover unscrewing itself while tightening the tank back up after changing the coil. While this isn’t a major issue, it does quickly become annoying. However this could easily be fixed if Vaporesso switched the thread orientation of the top cap cover.

Finally the additional menu button to operate the settings on the Vaporesso GEN S is too close to the up and down buttons and interfere with wattage adjustments. Personally I would prefer the GEN S not to have a menu button and use the usual three clicks of the fire button instead.


Without a doubt the well featured Vaporesso GEN S is a lightweight dual 18650 battery mod, that when coupled with the enclosed NRG S tank produces some great flavours. However the NRG S just needs a little refinement to be close to perfect. Nonetheless thanks to the Super Player Mode opening the resistance range from 0.03-5Ω and a selectable wattage range of 5W-220W. The GEN S mod will likely to remain in use with future purchases of tanks, be they stock coil, RTAs or RDAs.

Importantly if used at higher wattages, ensure the batteries are suitable for the amperage.
