When old Bill Shakespeare penned the line “though she be but little, she is fierce,” he must have been talking about the Tesla Stealth 40W temperature control box mod. What? You didn’t know the Bard of Avon was a Vaper? Okay, we made that up, but trust us when we say that this little mod packs a lot of attitude into its small frame.

Tesla Stealth 40W Review: Sub Ohm Stealth Device

Introducing the Tesla Stealth 40w

Like all pieces of technology, vaporizers seem to be getting smaller in direct proportion to their inclusion of more advanced features. Teslacigs has successfully capitalized on this trend with its Stealth series of mods. Highly compact, these devices are made for the mobile lifestyle. The Tesla Stealth 40w takes portability to the extreme while maintaining plenty of functionality. Is The Best Online Vape Shop. Free Shipping. Shop Now!

Wattage and temperature control can be adjusted with the two buttons on the bottom of the device.

Despite its small size, this mod serves up 40w of power and offers temperature control via its Ni200, Titanium, and SS316 coil support. While you won’t be able to harness all the tweaks that extreme sub ohm Vapers crave, there is plenty of flexibility here that will allow you to produce significant vapor volume and get a great draw.

A key to the unit’s compact size rests in its unique submerged atomizer design. There is a 23.5mm diameter tank slot. You can choose your favorite sub tank or even an RTA, insert it in the slot, and the tank virtually disappears inside the chassis of the mod. An added benefit of this setup is that it does a nice job of protecting the glass of your tank. Most tanks on the market will be compatible with this mod, which really enhances its compact appeal. You can get comparable clouds and flavor without having to trudge out your big rig, and that’s handy when you need to grab your vaporizer and go.

The Tesla Stealth 40w can easily be dropped in a back pocket, and using a tank with a leak-proof design like Tesla Shadow tank insures that your e-juice doesn’t wind up on your jeans. The battery is a built-in 1300 mAh LiPo that employs many safety features and will power multiple vaping sessions before needing a recharge.

Teslacigs Stealth 40W Specifications

You wouldn’t necessarily expect a mod this size to boast such an impressive list of specs, but take a gander at these features:

  • Measures 1.85″ x 1.1″ x 2.4″, making it one of the smallest mods available.
  • The chassis is made from durable zinc alloy.
  • Built-in LiPo rechargeable 1300 mAh battery.
  • It weighs just 0.25 pounds.
  • VW/TC-Ti/TC-Ni/TC-SS/Bypass modes give you lots of options.
  • 7w-40w of power.
  • Maximum output voltage of 8v.
  • Maximum output current of 20A.
  • USB port.
  • Resistance range of 0.1 ohms-3.5 ohms in VW mode, 0.05 ohms-1.0 ohms in TC mode.
  • Temperature range of 200F-600F.

The unit boasts an OLED display that is clear and bright, and the Up and Down buttons are discreetly placed on the bottom of the mod alongside ventilation holes for the battery. The fire button sits on top of the mod. Teslacigs has made it available in blue, red, white, and black.

The Teslacigs Stealth 40w can be hidden in the palm of your hand.

What Comes in the Box?

There are two options for purchasing the Stealth 40w. The first of these is a body package which includes the mod, a USB cable for charging, and a stylish display stand. The starter kit, however, offers more value. It includes the mod as well as The Shadow sub tank from Teslacigs. This 2ml tank pairs extremely well with the mod and has some pretty impressive features of its own:

  • Delrin Drip Tip.
  • Top-filling system.
  • Heat-resistant durable glass.
  • Pre-installed SS316 vertical coil with a resistance range of 0.6 ohms-1.0 ohms.
  • Leak-proof design.
  • Adjustable airflow.

The starter kit also includes manuals and a USB charging cable. As mentioned above, most every sub tank on the market will work with this mod. The Shadow, however, is a powerful little beast in its own right and well worth the extra money you will spend on the starter kit.

Who the Stealth 40W is Designed For

The Stealth 40w is obviously made for vapers with an active lifestyle. This is a mod for people that want to toss a device in their back pocket, handbag, or glove box and have it ready at a moment’s notice. And let’s be honest, some Vapers value discretion. They want to be able to step away from friends when they are out, take a couple of draws, and put the mod away. Some scenarios just don’t mesh well with a full sub ohm rig. For those times when stealth vaping is required, this mod is a great choice.

Oh, one other thing. This isn’t meant to sound sexist, but women are absolutely going to love the Stealth 40w from Teslacigs. Sorry, guys, but some of you still think about your mods like you think about a pickup truck. Many women prefer a mod that’s compact, not a tank.

The Tesla Shadow tank is a great tank. But you can swap it out with another one if it’s 23.5mm in diameter or less.

Pros and Cons

The size of the Stealth 40w is its biggest virtue. You could easily make this a travel mod and carry it along on road trips when a larger rig just doesn’t fit the bill. The battery life is respectable for a small device, and pass-through capability will let you vape while you recharge. That recessed slot for the atomizer is an idea that more mods should copy. The first time you drop this device and see that the glass of your tank is still intact, you’ll be wishing all mods used a submerged tank.

On the negative side, and there is no way around this, 40w of power just isn’t going to appeal to hardcore sub ohm Vapers. The thing is, those Vapers aren’t really who this mod was designed for so 40w isn’t a big drawback.  Additionally, the airflow intake from the Tesla Shadow tank is located in a position where your fingers may block the airflow.  This can be easily overcome by holding the device with this in mind.

Teslacigs gets one important thing right, and that is an awareness that we live in a mobile society. Everything is getting smaller and more powerful at the same time, and the Stealth series represents a perfect balance of portability and performance.

Discreet Clouds

The Tesla Stealth 40W is incredibly small, but provides a ton of features. The only thing that offsets its discreet size is the impressive amount of clouds it can create. The Tesla Stealth 40W is a must have secondary device for me.

  • Small and discreet
  • Protective tank shell
  • Pass-Through enabled
  • Interchangeable Tank
  • Battery won't last all day
  • Fingers may cover airflow

I started vaping in January 2011 and haven't had the desire to smoke a traditional cigarette since. It inspired me so much that I created this website to help others like me who want to quit smoking. I hope you enjoy the site and please leave a comment.

  1. I have a Teslacigs Stealth 40 watt. I have temp control control off and at 40 Watts. Not sure if this is the right setting. What is the best ejuice to use in this mod? I want it to give a good throat but, and closest as possible to be like smoking a cigarette. Thanks!
