Wismec Reuleux RX200

The Wismec Reuleux RX200 has the same design and form factor as the Reuleux DNA200 – in different colors.

Even though both models have essentially the same specifications, the two biggest differences are price and chipset. 

The Reuleux DNA200 uses the Evolv DNA200 chipset. These chipsets are in short supply, so Wismec released the RX200 featuring a chipset claimed to be manufactured by Joytech.  While there are some features that are different in both chipsets, both have the exact same specifications for the core functionality. And the Reuleux RX200 is close to one-third of the price.

The Wismec Reuleux RX200 is available in two colors. At the left is the white unit with teal accents. At the right is the unit we received for testing and review, solid black. 

This is one solid unit. No button rattle whatsoever and all buttons have a light tactile feeling with a light clicking (more like rubber clicking noise – not metal to metal). 

The display is 0.69 inches (17.53 mm). It is visible in virtually all lighting conditions. It shows a graphical battery that displays the remaining battery life; atomizer resistance; wattage (in TC mode); temperature (in TC mode); and, the type of coil you are using. In wattage mode, you can use any coil you want with a resistance range of 0.1 to 3.5 ohms. Temperature Control mode supports Ni200, Titanium, and Stainless Steel with a resistance range of  0.05 to 1.0 ohms. There is a locking function to lock in the "room temperature" resistance.

In practical use, the Reuleux RX200 innaccurately detects the coil resistance. In wattage mode, it was always at least 0.2 ohms too high. In Temperature Control mode, it was at least 0.2 to 0.3 ohms too high. I was able to read the correct resistance twice, once in wattage mode and once in TC mode – but that was on a brand new coil only. After the coil had been used, even leaving it to cool down to room temperature resulted in a resistance that was too high. Once it reads the resistance incorrectly, the only way to get a consistent vape is to increase the temperature. This is only important if you change tanks on a regular basis, or clean out your coils.

It is only 84 mm in height. The odd shape means that you are unlikely to be able to wrap your hand and fingers around the entire device. It is only 50 mm wide, but also 40 mm in depth. That odd shape, though, does contribute to helping it feel fairly good in the hand.

The picture at the right shows the battery vent holes. These are larger than usual and there is a set of three holes on each side. There are also 20 vent holes at the bottom of the unit.

The finish of these units is quite good. The center frame of the unit has a nice smooth texture. The front and battery cover have a slight rubbery texture that help you hold the unit firmly. 

I did find, as other reviewers have, that the fit is not perfect. The battery cover is not a perfect fit, there is some vertical movement if you try it and the gaps across the opening are not consistent. The front portion is also not a great fit. On my test unit, the edge to the right of the buttons/display did not line up with the lines on the frame. For a price point that is nearly 1/3 of the DNA200 version, it's no big deal. 

First and foremost, this unit requires 3 18650 batteries (at 35 amps). These are connected in series, but the total power output is not as expected (4.2 x 3 or 12.6 volts) ... the maximum voltage output is 9 volts. There has to be a step-down (or buck) converter on this to limit output. It also means that you will get a consistent vape for a longer period of time, compared to other devices that max out at the battery maximum output. While vaping this, I expected the total vape time to equal about 9 ml of juice. I ended up getting over 13.5 ml of juice off of a fresh set of batteries that were fully charged externally. I was concerned about charging through the micro USB port on the front of the unit. Any multi-battery charging system has to have a load balancer to make sure each battery is charged at the same rate and that each battery does not over-charge. The first full charge I did through the micro USB port was a bit concerning, so I put the entire unit in a charge bag (just in case). No problem whatsoever charging through the micro USB port ...

While vaping ...

I have several mods that are multi-battery and reach 200 watts or more. With the availability of these devices, I can't see myself (or anyone else) paying a premium to get a DNA200 device. This Wismec Reuleux RX200 may not have all of the features of a DNA200, but the features lacking are not commonly used. I thoroughly enjoyed using the Reuleux RX200 – more importantly, the price is outstanding for what you get. 

The only "glitches" that I encountered I could not replicate. Twice I ended up with not getting a satisfactory vape after fiddling with the settings to test them out. I could not get a good vape until I switched from temperature control to wattage mode and fired at a low wattage, then returned to temperature control. It's almost like it needed a reset. I was not able to do it a second time with either of the tanks this happened with. Other than those two issues, the Reuleux RX200 is a performer. 

I did try it in wattage mode with a clapton 0.5 ohm coil. Excellent vape. The maximum wattage I worked with was 40 watts, though. I also used it in temperature control with an Aspire Ni200 coil at 0.25 ohms and with a Atom Clapton Ni200 coil at 0.15 ohms. The more enjoyable vape was with the Atom Clapton Ni200 coil. I tried various temperatures, all the way to 600 F and found the unit to be fairly accurate in the vape consistency with the temperature as accurate as other devices.

So, what’s the verdict? Is it worth it?

At this price point, I wouldn't hesitate to get one. It's just slightly more than 1/3 the price of the Reuleux DNA200 and has all the features you would want of a temperature control mod. For cloud chuckers that want to kick out wattage, this unit will fire at 200 watts with coils that are 0.4 ohms or less. Ohms Law kicks in above 0.4 ohms that restricts the wattage to a lower level. I am always concerned with multi-battery systems – it's a safety issue. Particularly when they also include the ability to charge the batteries in the device. I ended up charging the unit quite a few times. I suspect the built-in charger is operating at 1.0 amp, charging time was reasonably fast. After charging in the device, I removed the batteries to check the charge levels and they were all consistent. The size of the unit is the only concern. If you wear a medium sized glove or larger, this is appropriate for you. Any smaller, and I would consider passing on getting one of these. Color availability is quite limited, you only have two choices. I plan on adding some carbon fiber wrap to mine to dress it up a bit. Grab one, you won't regret it.

And one quick note: it has not replaced my favorite mod. But, if I had this one first, I may not have acquired what became my favorite ...

Review Update

Please be aware that there are problems with some tanks and the Wismec/Jaybo Reuleux RX200. One of the tanks most frequently mentioned is the TFV4. You can read about it here, along with Wismec's response.

We've experienced problems with some tanks (Smok TFV4, Smok GCT, Aspire Cleito) and an intermittent issue with the Uwell Rafale. An older tank with short threads will not make a negative connection. A close look at the Wismec/Jaybo shows the 510 pin is slightly off center as well after about one month of use.
