For this review we are going to be taking a look at a gorgeous modern little kit – the OBS Engine 100w.

This is a traditional sub ohm device, paired with the OBS S tank.

OBS as a company has been around since 2014, are based in China and have a well respected name within the vape industry!

The Engine RTA’s series certainly made its name, as well building the brand name for quality and functionality.

The company has bought us the Cube series of mods as well as some RDA’s like the Crius RDA; OBS have also released a few pod systems like the Skye kit and Cabo kit.

What Can We Expect From the OBS Engine 100w Kit?

The OBS Engine 100W Kit is a pocket friendly sub ohm kit, designed for Direct to Lung vaping, and includes the 2ml TPD compliant S tank.

Powered by a choice of removable batteries to provide a maximum output of 100W, the device can be customized with replaceable battery sleeves.

The chassis for OBS Engine 100w Kit has been produced in two series – Stainless Steel and Gunmetal – each has 6 distinctive coloured resin battery sleeves to choose from.

As always my thoughts and views are my own after a considerable testing period.

It’s one piece with O rings at either end to hold the glass in position and the fill port is wide.

On the base you will see that OBS has lightly engraved the required information, and the connection point is a gold plated pin.

Inside of the base are 2 small gold plated protections that make contact with the coil.

The airflow for this tank has a bottom triple airflow, what you put one on it is mirrored by the other two.

The 2 coils that OBS have included with the kit are:

  • E1 0.4Ω mesh coil, 45 to 55w best at 50w
  • E2 0.2Ω mesh coil, 50 to 70w best at 60wincluded coils

I couldn’t find other replacement coils for the S tank online at this time!

How Does the OBS Engine 100w Perform?

For this review I will be using the pre installed 0.2Ω coil in the S tank

The liquid I will be using today is Summer Vibes “Blood Orange & Grapefruit”.

OBS Engine 100w Quick Start Guide

OBS 2ml S Tank

  • Always Prep your coil before first firing your device – drip a few drops of liquid onto the cotton.
  • Re assemble the tank and remove the top cap fill with liquid, replace the top cap and screw the S tank on to the OBS Engine 100w mod.fill tank s 2ml

Wait a 2 minutes before firing so the cotton can soak up more liquid.

OBS 100w Mod

Install a battery – you can charge a battery while it is installed in the mod safely, however I tend charge all batteries via my external charger.

  • X5 presses of the fire button to turn the device on and off.
  • You will be asked which battery you have installed. type battery menu
  • To change the theme colour press the fire button X3 times for each colour.
  • The device has an auto lock to change the wattage press either adjustment buttons X3 then scroll to your preferred wattage!
  • To clear the puff count press the – and fire buttons together.

The device has several safety features built in – overheating, overcharging and reverse polarity!

OBS Engine 100w Kit In Use

Starting at 45w with the airflow on the S tank closed to the half point, I received a decent restricted DTL draw, the vapour was good and cloudy surprisingly the flavour wasn’t too bad either.

Upping the wattage in 5w increments until I reached 70w, I found the higher up I went the vapour became a lot warmer; I was surprised to find the flavour was still good, although I did get a little spit back at 70w!

obs engine 100w 45w 2ml puff

Switching over to my OBS Engine Nano RTA with the airflow almost closed so I could enjoy a loose MTL style vape at 15w, the Engine 100w mod functioned very well producing a standard amount of vapour and a better than average flavour from my RTA which was no surprise!

OBS Engine 100w Battery life

With an 18650 battery the maximum the wattage is 60w!

With 20700 and 21700 both reach the full 100w.

I have tested all 3 types of battery in the mod and with the S tank.

Below are the rough times that battery lasted me at 60w!

  • 18650 – 2 ½ hours
  • 20700 – 3 ¾ hours
  • 21700 – 5 hoursobs engine 100w choices battery

Of course battery life depends on your usage, I am a heavy vaper so my times might not match yours.

OBS Engine 100w My Experiences

When I first started using the kit I couldn’t get used to the idea of the auto lock, pressing one of the adjustment buttons 3 times before I could adjust the device.

After a few days this was ingrained in my brain lol.

Another point I want to make is at higher wattage the 2ml tank drinks faster than a sailor on a weekend pass!

I have now purchased the 6ml bubble glass to solve this small problem – while still a thirsty little tank at least it’s now tolerable to me!

Pros

OBS Engine 100w Mod

  • Good quality
  • Well designed
  • Easy to use
  • Comfortable in the hand
  • Good battery life (21700)

OBS 2ml S Tank

  • Good flavour
  • Good vapour production

Cons

  • 2ml tank (need I say more)

Final Review Verdict

This really is a cute kick ass little vape kit!

The kit is well made with good quality, it’s small enough to keep in your pocket and comfortable enough to hold for an extended time, 5hrs with a 21700 is plenty of vape time for me as a travel mod!

My only real negative point after using the device for 1½ weeks is the fill capacity of the 2ml S tank and how it empties so fast – I now have the 6ml bubble glass to solve that.

I tend to be rather wary with stock coil tanks as they never seem to deliver for me, so I was rather surprised to find the tank produces good flavour and vapour quality!

Would I recommend the OBS Engine 100w Kit?

“Yes” ideal kit – for those who want to give DTL a go or for those with more experience that are looking for a small pocket friendly vape with a kick behind it!

Would I buy this kit again due loss or damage?

I will be buying another as Mrs J wants one lol, even so if it was lost or damaged! I would still replace it.

So…

Is this a vape kit you’re looking to buy?

Hi my name is Kevin, I started vaping back in 2009 mainly because my little boy at 3 years old was starting to copy the way daddy smoked a cigarette! Over the years I have gained a good amount of experience with different types of vaping hardware but I'm just a normal guy who enjoys sharing my experiences. This is why I started my Youtube vape review channel in 2014. To date the channel has had over 500,000 views. Being disabled, vaping has given me a gateway to meeting people from all different walks of life, many of those I would not have met under other circumstances. The way I look at my reviews is, if I can convince just one person to give up the stinky’s my job is done. I class myself as a tinkerer as I like to take things apart to see how they work and put them back together, yes that includes e-cigarette mods! One day I would like to be able to design my own mod. I am a dedicated father, and husband to my sweetheart of nearly 30 years! Family to me comes before anything else.

1 COMMENT

  1. I’ve been using Obs cubes for a while now
    What I find is any liquids under 80/20 tends to leak a bit
    There a great little mod and as a Driver I tend to vape like a demon
    I some times stick my Steam Crave and a 15ml bubble glass on and still get a great vape from it
    Must try the new one soon
