OBS Engine II RTA | Key Features & First Impressions

Be Sociable, Share!

    Out of the box, the dual-coil deck totally confused me. It has a really unique two-post system that requires an inverted coil installation. That means the coils hang by their leads to be trimmed from above. I’m not sure if this is “new,” but I’ve never built on anything quite like this. Even after it occurred to me how to build it, there was a lot of readjusting to get the coils in and placed where I wanted them. It looks like a spacious deck, but it feels kinda cramped when I build on it.

    The filling method is the same as the other OBS RTAs. It has a hidden side-fill ring that slides up for refilling with any size dropper. Setting the ring back in place reveals the three top-airflow slots. Although they come at 7.5 mm x 2.5 mm each, the airflow slots don’t provide as much air as they seem like they would. There is a fair level of restriction to the draw.

    A key departure from the previous versions is the airflow-to-coil system. This is what really elevates the performance from the already-great predecessors. The air comes in from the top and down through the sides of the inner chamber to hit the coils from below. I’ve always had an affinity for atomizers with bottom-fed airflow, and the Engine is further confirmation that this is the best way to get great flavor.

    Wicking the Engine 2 requires a bit more cotton than usual because the wick ports are large. Unlike the original that had GTA-style holes to wick, these are large diamond-shaped ports. This is not the RTA to have your wicks just hovering over the ports or it will biblically flood due to their size. That’s not to say stuff the ports, but don’t skimp on the cotton.

    On one hand I really like what’s under the hood of the Engine II, but it’s a little trickier to get right than I think it needs to be. I’m not a fan of how to trap the leads, and I don’t like the Phillips head screws OBS used. All the screwdrivers I’ve tried often slip out and don’t catch in the screw firmly while tightening. It’s almost as if the screws are stripped though they aren’t. I have to push in firmly while turning the driver – more than what is typically required. It doesn’t feel as secure to me as building on the Velocity-style deck of the original.

    Aside from the issues I have with the screws and the deck, the performance is what you’d expect from an OBS tank. Super solid performance! It provides rich flavor for days. My favorite juice has rarely tasted better out of an RTA at a similar power range (80-90 watts). But while I love the performance, it’s not a tank I would recommend to vapers new to rebuilding. However, if you are an experienced RTA user, you should really try this one out.

      All You Need to Know about Vaping Nicotine

        Sub-ohm Vaping – If you want to try sub-ohm vaping then you may need to rethink your nicotine level. As well as an increased level of VG you will likely need to reduce nicotine, as the inhalation from a sub-ohm vape is more powerful than standard vaping. As you consume more juice in a single hit so it follows that you take in more nicotine, leading to the risk of mild nicotine overdose. Juice for sub-ohm vaping generally comes in one of three strengths, 0mg, 3mg and 6mg. You can sub-ohm with higher than this, but, be forewarned, it will likely be unpleasant for a lot vapers.

        Deterioration – PG, VG, and nicotine tend to degrade over time, with nicotine degrading a bit more rapidly. Flavouring also fades, but to a lesser degree. As time passes nicotine will turn a yellowy-brown colour, and take on a peppery, stale odour. But many vapers vape e-juice that has aged for long periods, since the nicotine in e-juice isn’t at a high enough level to catastrophically alter the taste.  When in doubt, throw it out. But if it tastes good, go for it.

        Side-effects – While vaping means less exposure to harmful chemicals found in smoking tobacco, it doesn’t mean nicotine is totally harmless in and of itself. There is a general consensus (although it’s increasingly debated) that nicotine is addictive; it is classed as moderate-low for physical dependence and moderate-high for psychological dependence. It has been shown to raise blood pressure, elevate heart rate (both at the time of consumption) and is not recommended if used during pregnancy. Conversely, it also has performance-enhancing abilities, particularly when it comes to attention, memory and motor skills. f you look closely, the pros and cons closely mirror the effects of caffeine.

        Impact Time – Nicotine from cigarette smoke reaches the brain in under 10 seconds, and it reaches the central nervous system in under five minutes. However, anecdotal evidence suggest the particle size of cigarette smoke is much smaller than those found in vapour from e-juice. This implies the absorption of nicotine from vaping can take longer than smoking, perhaps up to 30 seconds before it reaches the brain. It is often suggested that smoking causes a harder faster nicotine hit, while vaping has a gentler, slower effect. Again, more studies are needed to get a true picture of this.

        Time In System – As with smoking, this depends on a number of circumstances such as metabolism and length of time spent as a smoker or vaper (and the amount/strength of the nicotine consumed), but traces of nicotine (via its metabolite, cotinine) are usually detectable for 48 to 72 hours after your last intake. Cotinine tests can be purchased cheaply if you want to check for yourself.
