The RX200S is a slightly upgraded and improved version of Wismec’s popular RX200 device. Just like its predecessor it requires three 18650 batteries and offers a maximum output of 200 Watts. The RX200S boasts a larger and easy to read display and uses the very latest Wismec chipset. The device has Variable Wattage and Temperature Control functionality and supports all popular wire types and is fully firmware upgradeable.

Wismec Reuleaux RX200S styling and build quality

For all intent and purposes the RX200S is almost identical to its predecessor, the RX200. It has the same high quality build and feels incredibly robust. Just like the Reuleaux DNA 200 and the RX200, the RX200S is a rather weighty device but if you were constantly using it you would certainly get used to it although it isn’t really a device you would want to carry around with you. Not every vaper out there will be a fan of the weight of this device but in terms of size the mod isn’t much bigger than a lot of dual 18650 battery devices.

The 510 connector has Stainless Steel threading for maximum durability and the pin is spring-loaded so all of your atomizers will sit flush on this device. The three buttons on the RX200S are excellent and feel very comfortable to use. Thankfully they do not rattle at all and feel quite durable.

Despite the weight, the RX200S is very ergonomic in design and it does feel very comfortable to hold. The casing is identical to the RX200 with the 0.96 inch OLED display being the only obvious change. The display is certainly much larger but while being easier to see I can’t say I am a massive fan of the font used, the block lettering doesn’t immediately read as well to me. The orientation of the display has also been changed (was horizontally aligned on the RX200) and you can now read it while the device is stood upright.

I am not sure if this was a necessary change since I have got into the habit of tilting my devices to read the display but some people may prefer it. The menu navigation is similar to the RX75 so I wasn’t a huge fan of that change since I happen to prefer the menu on the RX200. One plus point is that the battery life can now be displayed as an actual percentage instead of just a bar. All of the typical features you would expect are shown on the display such as Wattage, Voltage and Resistance. In addition, temperature is shown when using that mode as is the battery life. The brightness of the display definitely seems dimmer than the RX200 which is certainly something that might potentially bother you.

The battery compartment is well designed and features four strong magnets which keep it very secure. It is slightly tricky to get the lid off due to the strength of the magnets and you kind of have to dig your nails in to the little inserts on the casing but I personally prefer this to a device that has a very loose battery compartment lid that constantly falls off. The correct orientation for the batteries is clearly marked and there is a ribbon to assist with battery removal.

This device has plenty of venting and just like the RX200 it has three holes per side on the upper casing in addition to a further twenty holes in the base. The Micro USB port is located on the bottom front of the device but to be honest you will only ever use it for firmware updates and not for actual charging because to charge the batteries via USB would take alot longer.

Ease of use

The manual is very thorough and covers all of the functions of this device. In operation the new menu system of RX200S has more in common with the RX75 than with the RX200.

Wismec Reuleaux RX200S performance

Performance wise this device cannot be faulted and it works superbly! Of course this isn’t really that surprising given that the Reuleaux RX200 and the RX75 also worked flawlessly.

Whether running this device in Wattage mode or Temperature Control you will certainly get a very consistent and satisfying vape. This is the fourth Wismec device I have reviewed to date and I have to say that one thing I cannot fault them on is their excellent performance and accuracy.

The chip in this device and also the one in the RX200 allows the user to customize temperature control by tweaking the TCR curves in firmware updates. For those who prefer even more customization the Reuleaux DNA 200 is definitely the superior option but for most users the options on the RX200S will certainly tick all the boxes and be more than satisfactory.

As you might expect from a device that takes three 18650 batteries, the RX200S will last you a very long time between charges if you’re a modest user who vapes at say 10-20W. Users who vape at 30-60W will also get a good amount of life out of this device, in fact slightly more than a dual 18650 mod. For those people out there who like to vape their RDA’s and Sub Ohm tanks at 100W+ the RX200S will still give you a reasonable amount of time but the batteries will drain considerably faster.

Most vendors selling this device typically offer it as a deal with three included batteries but I would honestly suggest you get at least two sets of batteries because they do take a considerable amount of time to charge.


While I do feel that some of the changes were a little unnecessary the RX200S is another excellent device from Wismec. Its advantages are a longer battery life and a consistently flawless vape experience with its only real negative being the overall weight.

To be honest I don’t think that you should rush out and trade in your RX200 for the new RX200S because the upgrade frankly doesn’t really offer a great deal but if you’ve been on the fence about getting one of these devices then the RX200S with its newer chip is probably the better option. Having said that all of the Wismec devices are appealing and work extremely well so the question is really down to which one you prefer the most.
