After a huge success with the Engine RTA, OBS has released a single coil Nano version of the RTA to compete in the single coil market. Although it’s a ‘Nano’, don’t let its name mislead you! OBS has incorporated a lot of the same great features of their standard model onto their Nano version with a few small changes. The Nano features a single-coil build deck instead of the original Velocity deck and an improved airflow system to improve flavor. Can this RTA compete against the other great single coil RTA’s or is this just another rushed product? Let’s find out.
Here are the specs of the RTA:
· Size: 25*54.5mm
· Weight: 52g
· E-liquid Capacity: 5.3ml
· Material: 304-Stainless
· Top airflow system
· Patented top side filling design
· Endurance and big e-liquid capacity
· Precise design of air circulation system
· Accurate locating Bar and Slot design to perfect align your airflow
· Leak-proof
What’s in the box:
· 1 x Engine NANO
· 1 x Spare glass
· 1 x RTA Accessory series bag
Packaging:
The OBS Engine Nano comes packaged the same as any other of their products. Inside the box you get your Engine Nano, an Allen key, a spare glass, user manual and spares. At first I expected this Nano version to be smaller than the Engine (standard model) but instead, it is actually the same size as the original and holds a tad bit more juice than the standard model.
Design:
Visually, the Nano and the Standard model is identical besides for a small engraving of the word “Nano” on the chimney section. The previous engine, had gained recognition for its top-airflow only option which prevented leaking completely. The same system has been implemented with this RTA with a few minor tweaks done to improve flavor. This RTA really is a beauty, especially in black. It has a 25mm diameter and holds up to 5.3ml of juice. It’s definitely on the big/bulky side but nowadays with exotic coils becoming the norm, it may be a pro to you. The build quality of this RTA is fantastic! The machining is excellent and the threads are nice and smooth.
Building and Wicking:
Setting up the OBS Engine Nano is very easy. The Engine Nano deck has a simple two post design. The posts are very close together and the post holes are ‘staggered’, making it easier to insert your coils. This tank is a breeze to build on and doesn’t require much/any experience.
The most important thing when it comes to this RTA is the wicking. The bottom of the build deck has two large wicking slots that lead directly into the juice well of the tank so you have to make sure that the cotton goes through these holes to reach the e-liquid. Your cotton should be thick enough to prevent flooding which will result in spit back, but not too thick to prevent e-liquid from saturating the wicks. That said, wicking this tank is also an easy task.
Like its predecessor, the Engine Nano features a ‘notch’ system that requires the base and the tank to be perfectly aligned in order to assemble it together. So make sure that the two little notches on the inner barrel of the tank are aligned with the two grooves on the bottom of the build deck and that the bigger airflow hole faces the front of the coil, when putting the tank together.
In the standard model of this tank, the air hits the coils from above, coming through two slots on the top of the chimney. With the Nano, they are positioned on the sides of the chimney section, to improve flavour. IMO Flavor could have been a tad better if they removed the airflow that hits the coil from behind.
Refilling:
If you have used any of the side fill OBS tanks you would know how easy it is to fill. The fill ports on this RTA is massive so you won’t be having any issues with big droppers or anything like that.
Performance:
After using this RTA exclusively for about +-2 weeks, there's a couple of things I have noticed. The lack of bottom airflow means you don’t have to worry about leaking, but also that any flooding in the chamber due to incorrect wicking will result in spit back so its very important that you wick this RTA correctly.
Using the Clapton coil they include with the RTA, the performance has been excellent even at 40w. The flavor it produces is great and the vapour production is excellent. For a single coil RTA, I am definitely impressed with the vapour production. This RTA has more airflow than I am used to so I do close up the airflow a bit as I like a nice restrictive lung hit. This is definitely not a MTL style RTA at all and has a lot of airflow.
Pro’s:
· Great flavor
· Great vapour production
· Easy to build and wick
· Extremely user friendly build deck
· Excellent build quality
· Leak-proof
· Lots of airflow
Cons:
· May get spit back if wicking is incorrect
· *Too much airflow* (Subjective)
· *Somewhat noisier than other RTA’s*

it's named the engine and its it's named rightfully so.
any idea which vendor has them?
