Yihi SXMini G Class box mod
This week I am taking a look at the Yihi SXMini G Class, a temperature regulated and dual 18650 box mod.
The Yihi SXMini G Class comes in the older style white card box, little bit sad we don’t get this mod in the newer black ‘vinyl’ box.
Inside the Yihi SXMini G Class box we have a white envelope with all the user guide, warranty card etc. inside along with a USB cable (boxed) and the Yihi SXMini G Class itself (carefully wrapped up in a ceranwrap type sheath).
The user guides for the Yihi SXMini G Class are vast, here we have a few sample pictures of the user guide.
If you want to read the user guide in more detail here is the pdf of it PDF
Along with the user guides (and the device of course) we get a box with a USB cable inside.
This is not your generic, mass produced cable but a braided and branded USB cable.
As I said earlier the Yihi SXMini G Class comes wrapped in a protective sheath, so let’s get it unwrapped and take a look at it…
So, here it is the Yihi SXMini G Class box mod.
This is the ‘Carbon Black’ version, and it has a stunning carbon fibre body with black panels.
The level of detail and finish on this device is fantastic. It also comes in a black or a brown ‘leather’ (not seen them but probably leather effect vinyl) version.
The Yihi SXMini G Class is rather wide due to its large colour screen and control systems, it measures in at 32mm deep (by 47.mm wide and 93mm long).
With a device this size Yihi could either put a (standard) sized 510 mount or, as they have done, put a large 31mm 510 mount on it.
It, of course for Yihi, features a stainless steel base and a self adjusting, sprung, brass positive pin.
Yihi obviously wanted great looks for this device. Not only do the metal panels add grip to the Yihi SXMini G Class but they also get scope to add aesthetics as well.
The side bars add grip to the device and have writing that tells you about your product, the back panel has the SXmini brand name in large letters on it (more on this feature later).
The base of the device has the battery door, a button slides to unlatch the door and expose the battery compartment.
The door is labelled with B1 and B2 for the two 18650s and has a positive and negative marker to indicate which end of the battery should be up on that side.
There is also a ‘mystery’ third contact in the bay and on the door, this allows for balanced charging (in the device) and independent voltage monitoring of the two batteries in use.
You will have to forgive the poor condition of my workbench batteries, they have seen a lot of action.
So I mentioned the rear SXmini brand logo earlier. What I didn’t say was when the device is used (when the fire button is pressed) the logo lights up.
Whilst the logo isn’t especially bright under my photo-lab lights, it is more that adequate in regular lighting.
The front of the Yihi SXMini G Class is where all the action is.
Starting at the bottom there is a USB charging port, the menu button which is a four way ‘joystick’, a hexagonal fire button and the huge colour TFT IPS (better colour,clarity and viewing angle than regular TFT) screen.
Here we have the main display of the Yihi SXMini G Class.
I have mine setup for temperature regulation, so the display shows joules rather than watts.
The main screen displays a host of information, starting from the top left you have output volts, atomiser ohms, target temperature under power.
Then the user set output power, below that is the coil type, bluetooth logo (grey as its disabled on mine but it illuminates when connected) and used joules.
On the bottom row we have the remaining battery power, which memory bank is in use and the power output curve type.
A click up on the joystick will allow screen brightness to be changed, further up presses will increase the brightness and down presses will decrease it.
All of the screen pictures in this review were taken under my bright studio lights with the brightness set halfway at 5.
A press to the left will allow you to change the current memory bank, there are 5 to choose from and further left clicks will cycle through them (round-robin).
A click to the right will allow you to cycle though the various power output curves.
These curves vary the power over time of the output. There are a few of these (eco, soft, standard, powerful and power plus) and it is best to read the user guide pdf above to learn more about them. There are also 5 user defined curves you can select.
Pressing the joystick in (like a regular button) allows you to cycle through the main display item.
In my case that would be joules, temperature, coil type, watts and back to joules again.
In each case you can push up or down to increase or decrease the value.
Three quick fire button presses will lock the device and display a nice clock.
Three more presses will unlock it.
Five presses of the fire button will enter the menu screens.
There is a lot of tweaks and setting in here but for now I have just shown you the categories.
If you want to want to know more about all these menus then the pdf was earlier in the review.
Being Yihi they have a wealth of information and support options, the device will even show you them.
One thing I didn’t mention, in the dimensions of the device earlier, is how light this device is.
One my digital scales it weighed in at just 172grams.
On the subject of specs, here are a few more for you…

I have loved Yihi mods since I got my first one over two years ago. Every one of them has been a great product for many reasons.
The G Class is light, I mean if you have ever owned a S, M or ML Class the G Class weighs about the same (with two batteries installed) as they do (with just one).
Not only is it light but it is stunning good looking. I love the carbon fibre effect a lot. All the little nuanced aesthetics are fantastic and look spot on to me.
The G Class isn’t small, but for what it has in features and what it can do it isn’t really big either. In terms of width and height it is perfect but the depth is 32mm (largely because of the screen) and this does make it a handful.
On the subject of the screen, the colour and definition on it is amazing. Not only that but it has enough brightness to not get washed out by bright sunlight either.
Genuinely a perfect choice of screen.
The control system is rather new to me, took a little while to get used to it. I tend to not read user guides unless I have to, but I did dive into it to find out how to exit a menu and get back to the main display.
Once I had played about for a little while I had learned how it all worked and now find the menu system fast and easy to use. All the main stuff you will do is right there on the main display anyway.
The specs. and safety features are what you’d expect from YiHi, nothing to complain about or wish for.
If I had to find something to complain about at all on the Yihi SXMini G Class it would be the battery door lock. It could do with being grippy and not smooth, maybe a ‘ridged’ surface to make it easier to unlock. It is not hard to unlock but it could be easier and this idea would do that.
I am sure with a few weeks use it will loosen up anyway.
Additionally I felt the black ‘leather effect’ box that the Q Class and Q Mini came in just made them feel more exclusive, would have been nice to get the Yihi SXMini G Class in that box rather than the plain white one.
At the end of the day though, the Yihi SXMini G Class is fantastic and I am delighted with it.
The price for the Yihi SXMini G Class, well the suggested retail price is 239€. Expensive but at this price you are getting what I would call a high-end device.
