Honest review time: The Nunchaku 2 kit from Uwell

Uwell recently released an update to one of their more popular starter kits called the Nunchaku. Probably best known for their Crown series of tanks Uwell has been around for quite some time producing top quality devices and tanks. This new kit change things up quite a bit from the original with one of the only things remaining the same being the overall style of the device. I picked up the new kit from Sourcemore an online retailer that exclusively sells vape related products. It’s called the Nunchaku 2 kit and here’s what I think of it.

Packaging and contents:

The kit comes packed in a big black cardboard box with gold lettering and detailing. On the front is a depiction of the kit while on the back it lists the contents of the kit, some basic company info and plenty of warnings. In the kit you get the Nunchaku 2 mod, the Nunchaku 2 Tank with a 0.2ohm UN2 Meshed-H coil pre-installed, a 0.14ohm UN2 Meshed-H coil, a spare pyrex bubble tank, a pack of replacement o-rings, an 18650 battery sleeve, a micro USB cable and a user manual. Although there aren’t any real extras included you get the basic starter kit essentials and enough to get you started.

The Nunchaku 2 mod:

The Nunchaku 2 mod is a tube style or what some refer to as mech style device. It stands 100mm tall with a diameter of approximately 31mm at it’s widest however it bulges out at the grip and tapers in at the top with the top of the device where measures 26mm in diameter. Since it’s a bit tapered anything beyond 26mm will likely overhang a bit. Starting at the top it’s got integrated stainless steel threads with what looks to be a gold plated spring loaded 510 center pin. The threads are smooth and so far everything I’ve tried on it has sat nice and flush. Just below the top is the tiny black and white screen. Despite being small it’s bright and easy to read with all the usual information on there we like to see like wattage, resistance, battery bar and the mode. Just below the screen is a round plastic fire button. It’s textured with a swirly triangle pattern on it and sits just prominent enough from the device that it’s easy enough to locate and fire with the thumb or index finger.

On the side opposite the screen there’s a micro USB port for charging the device which it can do at a rate of 5V/2A so it’s got quick charge and will top up batteries quick depending on their capacity. On the bottom end of the device there’s a bit of branding and a little vent hole should anything go amiss with the battery but with the usual safety features built-in like short circuit, low-voltage, temperature and reverse battery protection things should be pretty safe in nearly any situation. The device supports the three most popular cell types for vaping which includes 18650, 20700 and 21700 batteries with a plastic sleeve to accommodate the smaller 18650 cells. To install a battery you simply unscrew the base and slide in the battery of your choice positive end up.

Now one of the biggest updates to the device is the way you control it. On the older version there were two adjustment buttons but on the new Nunchaku 2 there is only one button. It’s a really simplified system that uses the usual five clicks to turn it on and off and with three clicks you enter the very simply menu system which you then navigate by tipping the device either right or left. You also use the tipping motion to adjust wattage and temperature depending on the mode you’re in. In the menu you’ve got options for Power mode, TCR Mode, Mech Mode and Factory Settings. Power Mode operates like regular variable wattage with a range of 5-100W while TCR mode will be for temp control however it’ll most likely be only for the more advanced users as it expects you to enter the TCR value of the temp control material you are using. When you select the TCR mode it prompts you to pick the temperature, the wattage and then the TCR value which most new users won’t know. Mech Mode operates just like a mechanical mod would, drawing power directly from the battery but as the power still runs through the chip it retains the safety features mentioned above. Factory Settings just resets the device. Like I said it’s very simple with only a few modes to really chose from making it a good option for folks who don’t want to over complicate things.

The Nunchaku 2 tank and coils:

The tank that comes with the kit also received a considerable overhaul but still uses the same style of coils it just looks quite different. It too is made of stainless steel and comes equipped with a pyrex glass bubble tank. It holds a comfortable 5ml of liquid and comes with an easy off top fill cap. It only takes about a quarter turn to remove it and underneath it’s got a silicone membrane to help reduce spillage. The tanks stands roughly 34mm tall not including the drip tip with base a diameter of 26mm. It does bulge out at the tank to about 30mm but still matches up nicely with the mod. Towards the base of the tank is the triple airflow intake which can be adjusted by turning the airflow control ring. You can adjust it from a fairly tight direct lung all the way up to a fairly unrestricted direct lung. It also uses plug and play coils and to change a coil you simple unscrew the base, pull out the old coil and slide in a new one. You will need the tank about half empty before you swap coils though or you’ll end up with a mess.

As for the coils the new kit comes with some updated mesh coils which Uwell calls UN2 Meshed-H coils, the H I believe standing for honeycomb. The two coils are actually quite similar with the only difference being the density of the mesh they use. The kit includes one FeCrAl UN2 Meshed-H 0.2ohm coil rated from 50-60W which is best used in regular Power mode while the other coil is a SS316L UN2 Meshed-H 0.14ohm coil also rated from 50-60W but being stainless steel this one can also be used for temp control. The coils also have a built-in and patented self-cleaning technology which promises to reduce condensation build up by re-absorbing any lost liquid. In my nearly three weeks of using the device I haven’t experienced any leaking and condensation build-up has been almost non-existent.

I tried out the SS316L coil in both TCR and regular Power mode and to be completely honest I really didn’t find much of a difference between the two coils so it might just come down to personal preference on how you like to run them considering they both have about the same requirements. In TCR at around 300C and 60W it was a nice smooth vape, flavour was incredible and the clouds decent. When I finally switched over to the FeCrAl coil the only difference I noticed was a more immediate full draw where the TCR coil kind of starts off soft the FeCrAl coil ramps right up under regular Power mode. Again really incredible full flavour and big clouds and also a bit warmer as I was running it at the full 60W recommendation. Longevity of the coils will always depend on the juices you are using, personal vaping habits as well as QC on the coils themselves but I ran the TCR coil for a week and a half and probably could have kept going with it while the non-TCR coil has been going strong for well over a week now as well so they should be on par with most average mesh coils on the market.


With hardly anything to complain about, the Uwell Nunchaku 2 easily gets my vote for one of the best subohm mesh starter kits of 2019. It’s solidly built, easy to use, has great juice and battery capacity and just performs like a champ. One thing Uwell is well known for is the performance of their tanks and coils and the Nunchaku 2 tank and the UN2 Meshed-H coils leave absolutely nothing to be desired. It does cater more towards direct lung vaping but it’s also a super easy and convenient kit to pick up and use. This one will be best suited to both new users as well as seasoned vapers who just want a well made and solidly performing subohm mesh setup.
