I did a review of the OBS Engine Tank last year and I was completely blown away by it. It had to be one of my favorite tanks of 2016.
From the performance to the construction, everything about the OBS Engine was top notch. It was a cloud chasing, non-heating tank that had one of the smoothest draws I’ve ever experienced from a sub-ohm tank.
Apparently a lot of other vape reviewers felt the same way.
This is why I got excited when I was contacted by Heaven Gifts to review the 2017 versions which are the Engine Sub and Engine Sub Mini.
OBS Engine Sub and Engine Sub Mini Review
The two tanks are identical to each other and uses the same coil head, a disposable 0.3 ohm atomizer which is HUGE!
The disposable atomizers is what makes it different from the older Engine tank, which used a 2 post dual/quad rebuildable coil deck.
The only differences between the Engine Sub and Engine Sub Mini are the diameter and juice capacity: the Engine Sub has a 25 mm diameter and holds 5 ml of juice, while the Mini version is 23 mm in diameter and has a 3.5 ml capacity. The height of the 2 tanks is the same at 54.5 mm.
What’s in the Box?
Since it uses disposable coils, you won’t be needing any fancy tools or screws with this tank. It comes with an extra stock coil which is also at 0.3 ohms, an extra glass tank, extra o-rings and a user manual.
I’m glad OBS went the disposable atomizer route since I personally am getting a little tired of rebuildable atomizers. These new disposable coils that are coming out perform quite well when it comes to vapor and flavor production. It also saves me time and effort compared to using an RTA.
As for the construction of the tank, top grade as usual. I noticed the base of these new Engine Sub tanks are a lot beefier than the base on the previous OBS Engine tank.
OBS did a great job with sticking to what works. I love how the airflow holes are on top, and adjusting them are easy. Filling this tank with e-juice is a breeze thanks to the lift up sleeve which is located right under the air holes.
Because of the airflow holes and juice hole being located on top, this tank is a great purchase for vapers who are looking for a true leak-proof tank.
STRONG POINTS OF THE OBS ENGINE SUB AND engine SUB MINI
Aside from it being easy to use and leak-proof, the best thing about the Engine Sub is the vapor production. This tank really puts out big, dense clouds!
This tank is meant for vapers who like to vape at high wattage and enjoy that warm, dense vape.
As much as I loved the vapor production of this tank, I would have to say the biggest disappointment for me was the the flavor, especially for the Engine Sub tank.
Don’t get me wrong, it’s not a bad tasting vape at all. The only problem is the break-in period for the coil on the Engine Sub takes a little while, however it doesn’t take as long for the Mini version.
I don’t know if I didn’t saturate the coils enough, but I didn’t get that clean e-juice taste until after a few hits.
For a tank that produces so much vapor, I was expecting the flavor to be just as intense. The flavor just doesn’t match the vapor production.
Another thing is the draw. Like I said earlier, the previous OBS Engine tank had one of the smoothest draws I’ve ever experienced. These newer versions weren’t as smooth in my opinion.
Who is this tank for?
The OBS Engine Sub and Engine Sub Mini tanks are definitely for the cloud chasers, and since its so easy to use, I would even recommend them to the newbie vapors as an entry-level cloud chasing tank.
