The Best YiHi SXmini Mod Right Now
The YiHi SXmini MQ Class is the best SXmini mod to buy in 2026. It gives you the accurate output and temperature control YiHi is known for in a tiny, light and far more affordable device.
YiHi SXmini MQ Class
It weighs just 77g without a battery and runs YiHi’s SX416J chipset. Its 60W ceiling is more than enough for the MTL and lower-power RDL tanks it is actually designed to run.
| SXmini Mod | Best For | Battery | Maximum Output | Status |
|---|---|---|---|---|
| SXmini MQ Class Best Current Choice | MTL and lower-power RDL setups | Single 18650 | 60W | Available |
| SXmini MQ Plus | More power and 21700 support | Single 21700 | Higher-output compact use | New, limited availability |
| SXmini G Class | Collectors and dual-battery users | Dual 18650 | 200W | Mostly discontinued |
| SXmini SL Class | Single-battery power users | 18650, 20700 or 21700 | 100W | Difficult to find |
| SXmini Q Class | Classic dual-battery SXmini experience | Dual 18650 | 200W | Discontinued |
YiHi used to make some of the most interesting vape mods on the market.
The SXmini G Class, Q Class, SL Class and T Class were expensive, beautifully made and packed with the sort of temperature-control features that made experienced vapers go slightly weak at the knees.
But things have changed.
YiHi doesn’t release anywhere near as many traditional box mods as it once did. Most of its famous models are now discontinued, difficult to find or only available as old stock through specialist retailers.
That makes writing a “best SXmini mods” guide in 2026 slightly awkward. There isn’t a huge current range to compare. And if you want more options to choose from, check out my Guide To The Best Vape Mod Kits right now.
The good news? The model you can still buy is really bloody good.
The Best YiHi SXmini Mod Right Now
The YiHi SXmini MQ Class is the best SXmini mod to buy in 2026.
It is tiny, weighs just 77g without a battery and runs YiHi’s SX416J chipset. It only produces 60W, but that is more than enough for the MTL and lower-power RDL tanks it is designed to run.
It also costs considerably less than the $200-plus prices normally associated with SXmini hardware.
| SXmini mod | Best for | Battery | Maximum output | Status |
|---|---|---|---|---|
| SXmini MQ Class | Best current choice | Single 18650 | 60W | Available |
| SXmini MQ Plus | More power and 21700 support | Single 21700 | Higher-output compact use | Newly released, limited availability |
| SXmini G Class | Collectors and dual-battery users | Dual 18650 | 200W | Mostly discontinued or old stock |
| SXmini SL Class | Single-battery power users | 18650/20700/21700 | 100W | Difficult to find |
| SXmini Q Class | Classic dual-battery SXmini experience | Dual 18650 | 200W | Discontinued |
The newer SXmini MQ Plus has also appeared, adding a single 21700 battery and the newer SX418J chipset. However, its retail availability is still patchy. The standard MQ Class remains much easier to find and is the safer recommendation right now.
YiHi SXmini MQ Class: Best SXmini Mod Overall
- Best for: MTL and moderate RDL vapers who want a small, accurate mod for tanks running between approximately 10W and 50W.
The YiHi SXmini MQ Class is the SXmini mod I would buy in 2026.
Part of that recommendation comes down to availability. YiHi simply isn’t producing the enormous catalogue of mods it once did, while most of its older flagships have disappeared from mainstream vape stores.
But the MQ Class isn’t winning by default. It is an excellent little mod in its own right.
It takes the part of SXmini devices that always mattered most, the chipset, and puts it inside a body that is considerably smaller, lighter and cheaper than the company’s old flagships.
You get the SX416J board, proper temperature control, PURE technology, a replaceable 18650 battery and up to 60W of output.
You don’t get a huge colour touchscreen, two batteries or enough output for a monstrous dual-coil RDA. That isn’t what this mod is for.
A Proper Mod That Fits In Your Pocket
The MQ Class measures just 76 × 36.7 × 24mm and weighs around 77g without its battery.
That is properly small.
Attach a compact 22mm or 24mm MTL tank and you have a setup that can disappear into a jeans pocket without dragging your trousers towards the floor. Compared with a dual-18650 mod, the difference is enormous.
This makes the MQ Class particularly well suited to tanks such as:
- Kayfun-style MTL RTAs
- Compact single-coil RTAs
- 22mm and 24mm MTL tanks
- Lower-power RDL tanks
- Rebuildables running between 10W and 50W
If your favourite build runs at 14W, a 200W dual-battery mod is just dead weight. You’re carrying an extra battery and a much larger chassis to access power you will never use.
The MQ Class gives you the power you actually need in a much more manageable package.
The SX416J Chip Is The Real Reason To Buy It
Small vape mods aren’t difficult to find. Small vape mods with genuinely good chipsets are another matter.
The SX416J board is the reason the MQ Class feels like an SXmini rather than a generic 60W box with a posh logo on it.
Power delivery is accurate and responsive. The mod reads resistance properly, fires quickly and provides the type of temperature-control performance for which YiHi became known.
That matters if you use stainless-steel builds, temperature control or carefully tuned MTL coils. Small changes in power are much easier to notice at 12W or 15W than many people assume.
A cheap board might technically produce the same wattage, but it won’t always deliver it with the same consistency.
PURE Technology And Dry-Hit Protection
The MQ Class also supports YiHi’s PURE technology and NENV system, short for “No E-liquid, No Vape.”
When used with compatible hardware, the system monitors conditions at the coil and stops firing when it detects that the wick is running dry. The idea is to prevent dry hits and avoid scorching your cotton.
There is an important catch: compatibility.
You cannot screw any random tank onto the MQ Class and assume that every PURE feature will work. The tank, coil and wire need to be compatible with the system.
Even without PURE support, however, you still have a highly accurate regulated mod with good temperature control. The additional protection is a bonus rather than the only reason to buy it.
What Is Battery Life Like?
At normal MTL wattages, battery life is excellent.
A good 18650 cell running a 1.0Ω coil at 12W to 18W can last a surprisingly long time. Depending on how frequently you vape, getting through a full day should not be difficult.
Move towards 40W or 50W and things change. The battery drains faster, and running close to the 60W limit leaves almost no spare output.
That is why I see the MQ Class as an MTL and moderate-RDL mod.
Yes, it can technically fire a lower-resistance DTL coil. No, I wouldn’t buy it as my main device for running a thirsty mesh tank at 60W all day.
Use it within its intended power range and it makes far more sense.

- It is perfectly suited to MTL tanks and compact RTAs
- The removable 18650 battery can be replaced

- USB-C charging is included
- It feels like a high-end SXmini without costing SXmini flagship money
- It doesn’t waste space on a massive screen or pointless animations
What You Need To Know Before Buying
The MQ Class isn’t a universal vape mod.
Its 60W ceiling rules out many large mesh coils, dual-coil rebuildables and high-output DTL tanks. You can run it near 60W, but battery life will drop quickly and you won’t have much headroom.
The 0.69-inch screen is also small. It displays the information you need, but nobody is going to mistake it for the display on an old G Class.
The menus and temperature-control settings may take some time to learn if you have only used simple wattage-mode devices.
Finally, PURE and NENV dry-hit protection depend on compatible hardware. Buy it for the YiHi board, compact construction and accurate output. Treat PURE support as an additional feature.
Who Should Buy The SXmini MQ Class?
Buy it if:
- You mainly vape between 10W and 50W
- You use an MTL tank or compact RTA
- You want proper temperature control
- You prefer removable batteries
- You are tired of carrying heavy dual-battery mods
- You want an SXmini without paying old-school SXmini prices
- You care more about power accuracy than maximum wattage
Skip it if:
- You regularly vape above 60W
- You use large dual-coil RDAs
- You want two-day battery life at high power
- You need space for tanks wider than 24mm
- You want a large touchscreen
- You need a full dual-battery cloud-chasing mod
What Happened To All The Other SXmini Mods?
This is the slightly depressing part.
There was a time when YiHi regularly released large, expensive box mods with advanced SX chipsets. The G Class, Q Class and SL Class were serious competitors to DNA-powered devices from Lost Vape and other premium manufacturers.
Those mods still exist, but finding a new one in 2026 is difficult.
Most mainstream retailers no longer carry them. Any remaining examples are generally old stock, used devices or models sitting in specialist stores with uncertain warranty support.
That doesn’t automatically make an older SXmini a bad purchase. A clean G Class can still be an excellent mod. However, buying discontinued vape hardware creates several problems:
- Replacement parts become harder to locate
- Battery doors and screens may no longer be available
- Firmware support can stop
- Warranty claims become more difficult
- Old stock may have been sitting in storage for years
- Sellers can charge collector prices
If you already own one, keep using it. If you are buying your first SXmini today, the MQ Class is the far more sensible option.
What About The SXmini MQ Plus?
The MQ Plus is YiHi’s newer development of the same compact idea.
It moves to a single 21700 battery and uses the newer SX418J chipset. That should give it longer runtime, more power headroom and better suitability for moderate DTL tanks while retaining the compact MQ format.
On paper, it looks like the model many existing MQ Class owners will want.
The problem right now is availability. It is new, stock is limited and it has not yet appeared across the same number of retailers as the standard MQ Class.
Once the MQ Plus becomes easier to buy, it may take over as the best all-round SXmini. For now, the MQ Class remains the one I can recommend without sending you on a three-hour hunt through obscure vape shops.
Is The SXmini MQ Class Good Value?
Yes, unusually so for an SXmini.
Older SXmini flagships were often priced well above ordinary vape mods. Part of that cost paid for premium materials and elaborate designs, but you were also paying for the YiHi board.
The MQ Class strips away much of the expensive bodywork while keeping the bit you actually want.
At around $50 to $60, it competes with fairly ordinary mass-market mods. Yet it gives you a genuine YiHi chipset, excellent temperature control and a far more compact chassis.
That is a very strong deal if you vape MTL or RDL.
A 200W user won’t get much from it. Someone running a Kayfun at 15W probably won’t find anything better for the money.
Frequently Asked Questions
Quick answers covering the best current SXmini mod, suitable tanks, power requirements, battery replacement and older models.
What is the best YiHi SXmini mod in 2026?
The SXmini MQ Class is the best YiHi SXmini mod for most people in 2026.
It is one of the few current SXmini box mods that is reasonably easy to find. It combines the SX416J chipset, a removable 18650 battery and accurate 60W output with a tiny 77g body.
The newer MQ Plus may eventually replace it, but availability is currently more limited.
Does YiHi still make SXmini mods?
Yes, but it does not release anywhere near as many conventional box mods as it did during the G Class and Q Class era.
Its recent hardware includes the MQ Class and newer MQ Plus, while many older SXmini flagships are discontinued or increasingly difficult to buy new.
Is 60W enough?
For MTL and moderate RDL vaping, easily.
Most MTL tanks operate between 10W and 25W. RDL tanks commonly sit between 25W and 50W. The MQ Class covers both without making you carry two batteries and a much larger device.
Can I use an RTA on the SXmini MQ Class?
Yes. Compact single-coil RTAs are where the MQ Class makes the most sense.
Stick to atomisers up to approximately 24mm wide and builds that operate comfortably below 60W. It is particularly well suited to MTL RTAs and single-coil RDL builds.
Does the MQ Class prevent dry hits?
It supports YiHi’s PURE and NENV systems, which are designed to stop the device firing when compatible hardware runs dry.
Can the battery be replaced?
Yes. The MQ Class uses one removable 18650 battery.
This gives it an advantage over compact internal-battery mods. When the cell begins losing capacity, you replace the battery rather than the entire device.
Is the SXmini G Class still worth buying?
The G Class remains a capable premium mod, but buying one in 2026 comes with risks.
Most available units are used or old stock, and replacement parts are becoming harder to find. It can make sense for a collector or an existing SXmini user, but the MQ Class is the safer purchase for someone who wants current hardware and retailer support.
Final Verdict
YiHi doesn’t make loads of vape mods anymore.
The days of choosing between five or six current SXmini flagships are gone. Most of the company’s famous devices are now discontinued, expensive, difficult to find or some mixture of all three.
Fortunately, the MQ Class gets the important stuff right.
It is small, light, accurate and powered by a proper YiHi chipset. It runs replaceable 18650 batteries, supports excellent temperature control and has more than enough power for MTL and moderate RDL vaping.
The 60W limit will put off cloud chasers. Everyone else should ask themselves a fairly obvious question: if your tank runs at 15W, what exactly are you planning to do with another 185 watts?
For most existing SXmini fans, the MQ Class is the best readily available option in 2026. For anyone who has always wanted to try a YiHi-powered mod but refused to spend $200, it is probably the best entry point the company has ever made.
