SMOK Skyhook RDTA Box Mod review

SMOK Skyhook RDTA Box Mod

Remember the SMOK Alien that I reviewed a short while ago? Well now imagine that device combined with the new Skyhook RDTA (Rebuildable Dripping Tank Atomiser) and featuring a massive 9ml internal capacity tank because that is exactly what this new product from SMOK offers!

SMOK Skyhook RDTA Box Mod styling and build quality

The SMOK Skyhook RDTA is a very big device and even though it is essentially a SMOK Alienthat forms its core it is significantly larger. The device is 130mm long, 50mm wide and about 32mm thick. Despite its size it is very comfortable to hold due to its nicely rounded edges. It is quite well balanced but rather weighty once you fit two 18650 batteries and fill the massive 9ml tank to capacity.

The overall styling heavily resembles the Alien and shares many similarities such as the trigger fire bar, the display and the battery door. The colours are well done and punchy but what is nice is the fact that the included Skyhook RDTA is also colour coordinated.

Unlike other SMOK mods that are typically constructed from Zinc Alloy the Skyhook RDTA Box Mod uses Stainless Steel. The top section of the device is massive and features a 9ml juice capacity reservoir that has its own filling port and screw on cap. The tank also has a frosted window that allows you to keep an eye on the amount of juice you have in there.

The OLED display is exactly the same as the one on the SMOK Alien so I am not going to repeat myself too heavily (check my SMOK Alien review if you need more details) but it does feature all of the typical information you would expect including Resistance, Wattage, Temperature etc. I must admit that I still am not a fan of the display because all the information is bunched together and combined with the style of font makes it slightly awkward to read but you will probably get used to it in time.

Just like the SMOK Alien the firing trigger bar is comfortable to use and has a nice amount of tension. While it is responsive and works well I still prefer a standard fire button because navigating through menus using the trigger bar feels cumbersome to me but if you are used to SMOK devices you will probably feel right at home!

The battery compartment itself features a press and slide lid that is easy to use. The correct battery orientation is clearly marked on the interior, there is no ribbon to assist with battery removal but fitting and removing batteries did not present any problems. The device doesn’t have a huge amount of venting and features only a single Micro USB Port shaped hole in the battery compartment lid.

The Micro USB Port on the device is located directly beneath the two adjustment buttons. You can use the included cable to connect the device to your PC to charge the batteries or simply use an external battery charger. The cable also allows you to download firmware upgrades from SMOK.

The included Skyhook RDTA is nicely constructed and features a two post Velocity style deck which is very convenient to use. The deck features two large bottom airflow slots and the included airflow sleeve offers bottom and side airflow. To adjust the bottom airflow you simply turn the barrel and to adjust the side airflow you turn the Delrin top cap.

A separate sleeve is included in the box that only features the bottom airflow adjustment slots. A single coil adapter plug is also included. There is plenty of space on the deck and the two Fused Clapton coils are already pre-installed for you. All you need to do is pulse them sufficiently so they glow evenly before finally letting them cool and fitting your cotton. When you decide that it is time to fit a new pair of coils or swap to a single the post screws work well and hold the wire securely and since it is a Velocity deck it is very approachable.

Unlike the Skyhook RDTA that can be purchased separately this version has the whole bottom section cut out so your wicks will drape into the reservoir and be continually saturate. You don’t actually need to make your wicks very long because the tilting motion you make when naturally vaping allows them to remain sufficiently wet. The airflow adjustment works well and has a nice amount of flexibility.

Ease of use

The SMOK Skyhook RDTA Box Mod uses the same style of menu as the SMOK Alien and all of the features are exactly the same. The included manual does a thorough job of explaining all of the device’s functions.

When you first get the device it is worth giving the tank a slight rinse. I strongly suggest that you don’t put the device under the tap and instead fill a small bottle with water. Simply unscrew the fill cap and squeeze some water in there before replacing the cap and giving the device a light shake before once more removing the cap and emptying out the water. I personally think it makes the device a bit inconvenient to clean especially if you use strong smelling E-Liquids.

SMOK Skyhook RDTA Box 220W performance

For all intents and purposes the Skyhook RDTA Box is basically a redesigned SMOK Alien so in terms of performance they are exactly alike. The included Skyhook RDTA offers good flavour and gives you a very enjoyable vape while putting out a massive amount of clouds when vaping at 70W+ with the pre-fitted coils.

Having a 9ml tank of juice to draw on the RDTA wicks extremely well and at no point did I experience any dry hits. As you might expect when vaping at higher Wattage the batteries do drain fairly fast but you will at least get a few hours use out of it and due to the simple to use Velocity style deck you could easily replace the coils with higher Resistance ones or instead make a single coil build.

To test out the Temperature Control Mode I ripped out the two pre-fitted coils and fitted a single Stainless Steel coil which worked really well and I encountered no obvious problems.

As you can probably tell from the nature of its design the Skyhook RDTA Box is pretty much a one trick pony but I don’t mean that in a bad way because it is extremely good at what it does namely offering a dripper style experience with excellent cloud production backed up by a massive 9ml capacity E-Liquid reservoir.

Unfortunately you are limited to the included RDTA which thankfully does cater to single coil users but you can’t actually swap it out for any of your other atomizers. As such this makes the Skyhook RDTA Box much harder to recommend over the SMOK Alien Kit which is way more flexible, includes its own tank that can be swapped out and can be purchased for the same price or even £5.00 cheaper from some vendors. Another major issue with all of these all-in-one kits is that if something should ever break the entire package is rendered useless.

Even if you are a serious cloud chasing fan and love the concept of this device a very good reason to think carefully before rushing out to buy one is the fact that it leaks, sometimes heavily!

I first noticed the issue after my first day trying out the device and I set it down on my desk completely upright for a couple of hours. Upon returning to use it again I noticed that the bottom of the device, namely the battery door, was slick with juice. I opened up the compartment and noticed a small amount of juice in there so I removed the batteries and also found them to be wet with juice too. It goes without saying that E-Liquid and electronics don’t mix but thankfully after a good amount of drying out and cleaning the device still functions but the leaking issue certainly has persisted to the point where I don’t want to use it anymore in case I should ruin it.

When I first saw this design I did question the logic of having a huge internal reservoir of juice positioned directly over the battery compartment firstly because it is a pain to clean and secondly because of the potential for it to leak. At least when other all-in-one mods leak the tank is usually to the side and away from the batteries or electronics but that is not the case here.

It is unfortunate because as a device that directly caters to cloud chasing and RDTA fans the Skyhook RDTA Box potentially could have been excellent. The vape and performance it offers cannot be questioned but the leaking is a serious cause for concern and as such I can fairly say that I personally wouldn’t advise you to buy this device.

The possibility of course exists that not all Skyhook RDTA Boxes are created equal and that on this occasion I received a faulty product but I have read quite a few accounts of other people having exactly the same issue. Of course you might even be lucky and find there is nothing wrong with your Skyhook RDTA Box but do you really want to take the chance?


In terms of its styling and performance the Skyhook RDTA is excellent and in theory it should be an absolutely ideal all-in-one option for high Wattage cloud chasing fans but it does suffer from one very fatal flaw. Despite its many plus points the serious leaking issue makes this device very hard to recommend and the leaking will likely just end up ruining the electronics and your batteries. Not to mention that it could even be potentially dangerous.

Personally I would say that if you want a device like this with a similar styling then your best bet is to get the SMOK Alien Kit or just the SMOK Alien on its own and pick up a good large capacity RDTA to use on it. It really is such a shame that this device is ultimately a let-down because the vape it offers is excellent so I do hope SMOK addresses its one major flaw because at present I feel it would be a very poor investment.

Since we had no idea about this devices leaking problem until we actually reviewed it we had already purchased two of them and have an unused blue one to give away. Hopefully it does not have the same problem as the gold version but do be aware the potential is there so only enter the competition if you really don’t mind taking a chance on it.
