Sx Mini SL Class Review

Alright, everyone! Welcome to the down low portion of this video. Today, we’re going to be doing the SX Mini SL Class. Check out that packaging. They always do a really nice job on it. You’ll see the contents over here. Basically, we get one SX Mini SL Class, battery not included, USB cable, user manual, warranty card, warning card and a gift bag and box. I have the black tank color.

Let’s check this thing out. Always liked SX Mini’s packaging. Here’s the user manual right here. They always do a great job on that. Here is a little envelope with some more paperwork in it. See what we got. We have a upgrade and bluetooth instruction, right there. File that to the side. Battery card safety, gone. What’s this? Tips for 21700 batteries, gone. Warranty card, gone. In this box, we have a USB cable. As always, they’re high quality USB cable from SX Mini.

From Top To Bottom

Here is the SX Mini SL Class. As usual, let’s start off on top. We have a gold-plated, spring-loaded 510 that I would call very stiff with a medium throw. Smooth threading, buttery smooth, around here. Nice design on the top plate here, really diggin that. Loving these ridges like, right here. I think they’re fantastic. They give it a really nice look and I love this ledge right here. Great place to rest your thumb. That kind of a weird shaped fire button,over here, almost looks like home plate.

Here’s your screen, here’s your joystick, here is your micro USB port. Look at the beautiful edging on that plastic. It’s plastic but it almost looks like leather. Kind of has like a paisley pattern to it. They did just a bang-up job on this thing. I know it’s also available in stabwood on this part. I really wish they would have sent me a stabwood version, man. That would have been beautiful. I’ll probably go out and buy myself one. Diggin this brushed stainless steel look. A little bit of branding over here says, SL Class.

Here is your battery cap. Notice, it has very similar design to your 510 plate. Also, some venting over here. Same type of knurling, a little bit of SL Class branding over here. Threading on here is smooth. I think what you’re hearing is the knurling rubbing against that part. So it sounds rougher than it actually is.

Inside the battery compartment, you will get a hard plastic 18650 adapter. We’re going to put that to the side for now. You’ll see that the battery cap clearly marked, minus. So this goes in positive side up. See that? It’s hard to see on camera but it’s there. Really wish they would have made it a nicer color.

Down there, you have a gold plated battery contact that is spring-loaded. Tube is beautiful and clean they did a really nice job on it. Battery goes in, positive side first. This is a 20700. You can see, it’s got some room in there. Moves around but once you put the cap on, everything’s nice and tight.

But what I wanted to show you was, here’s a Snow Wolf 21700. Look at that. It doesn’t go in. It’s not going to go in so not all 21700s fit. Here’s an Aspire 21700 and if you wiggle it a little, it still won’t go in. Very, very tight and I don’t feel like they’re in my wraps. Here’s a Tesla 21700 and that one goes in just fine. So just be aware that not all 21700s are going to fit. For now, I have been running 20700s and some of my 21700s that fit okay tighten your battery cap down and you’ll see your SX Mini screen.

Menu System

5 clicks on. Wait for it to boot up and everything is controlled with the joystick. There is your screen right there beautiful bright colorful screen. Here’s your wattage, joules, resistance, voltage, amps, preset that you’re in. I’m in m4. That’s your preheat and here is your the voltage of your battery. Here is your battery meter. In order to change anything on the menu system, it’s all done basically through the joystick. Press the joystick to adjust your wattage up or down. You can see it scrolls pretty fast. Goes up to a 100W, does not round-robin.

We’ll put it back down to where I had it. I have it around 72. Hit the button again to go into Joule mode. Hit the button again to change your temperature. Now, you can hit the button again and you can scroll through your different materials. There’s Ni200, titanium, stainless steel 316 and TCR with nickel 200.

Now we’re back into wattage mode. You see right there, it says standard. If I want to change my preheat, quick hit to the side. I go to powerful, powerful plus, there are the SX-IQ presets. Go back into echo mode, soft. I normally leave it on standard. Hold the joystick button down to reread your resistance if you want to. Click the button five times, brings you into this menu system. System off, manual TCR or standby time. You can adjust it. If you want to shut it off, click the joystick button, it says bye-bye. Five more clicks and you’re back on.

Alright and that’s it folks. That’s really the whole menu system. Very simple, I’m definitely digging it.

Let’s cut back on top. Let’s talk about it. We’re going to vape on it, cons, pros and then we’re out of here. See you back on top.

General Thoughts

Alright, everyone! We’re back on top with the SX Mini SL Class. Check it out, man. Rockin my Augvape Templar on top, short and stout just like I like it. One of the best displays I’ve ever seen on a mod. The screen is bright, you can see it in all kinds of lighting conditions. It says I got Bluetooth instructions in the box but this thing doesn’t have any bluetooth, it just doesn’t. It’ll fire down as low as 0.05 ohms goes up to a 100W with a 21700 battery. 26mm on this thing, no problem without any overhang. Measurements are 88 x 35 x 27.5 mm. I dig it, man. Been loving the form factor. I don’t know if you noticed but my a SX Class is on the shelf and this is the mod that put it there.

Let’s go over the cons and pros. Couple little cons, not too many. Plenty of pros.


First con’s going to be, showed you in the down low, not all 21700s fit. Con on that.

Menu has a little bit of a learning curve to it that’s with all the Yihi chipsets with this joystick. Once you get it down, it’s not a big deal but I still got to give it a con for that because it’s not as intuitive as it could be.

No Bluetooth, they’re going to get a con for that they wouldn’t have if they didn’t put the instructions in the box because I don’t care about Bluetooth but you put the instructions in the box and the thing doesn’t have Bluetooth capability. That’s a con.

Next con is going to be the price point. Some people are going to have a problem with the price point. I gotta be honest. I don’t have a problem with SX Mini’s pricing because every mod I’ve ever got from them is extremely high quality. I’ll go as far as to say this is probably the best quality mod you can get from a Chinese manufacturer or one of them at least.


Let’s move on to the pros because there’s plenty of them. Love the look of it. Check it out. It’s beautiful. It’s classy looking. They did a great job on the looks. Love the form factor. They’ll get a pro for that.

Real nice form factor. Awesome chipset, pro on that.

Takes 18650s, 2700s and some 21700s, pro on that.

Build quality, I touched on it already. One of the best-built mods coming out of China, pro on that.

26 mm without any overhang on top, pro.

Easy to navigate, pro.

Great TC, listen, this chipset has legendary TC. There’s no doubt about it. It’s awesome, pro on that.

Accurate in wattage mode, pro.

Great screens, super bright. Pro on that.

Nice clicky fire button, pro.

No rattles, this thing has no rattles at all. All the buttons are in there solid. The battery stays in there solid, pro.

5 memory slots, we’ll give them a pro for that.

Firmware upgradeable, that always gets a pro on this channel.

2 amp charging, pro.


In my opinion, this is the best single battery mod on the market right now up to this point. Something might come out that beats it, but right now, this is the Big Kahuna in the single battery category as far as I’m concerned. Definitely DeucesJack approved.

    Just wanted to say that if anyone is having a problem in temperature control mode with the no juice protection then you want to press and hold the joystick to allow the mod to register the new coils resistance.

    SX Mini SL Class
    If you work with configuration of curves or memory DO NOT BUY THIS.
    Each time you take off batteries for recharge all customization is lost.
    80% of the time when you connect to SXi app (in Windows 10) the device is not recognized.
    Yihi NEVER answer to any email.
    They have only one (expensive) mod that is OK: Yhi 550J based chip. Works very well and does not needs Yihi support, that does not exist.
    FOR ME YIHI IS PASTED (although they have VERY GOOD mods … till you have the first problem)

    Firmware upgradeable? Where is the firmware? Where is the support? Never more YiHi chipset. Only the hype was big. This chipset a piece of shit.
