Shop for the latest & greatest Yihi Products from Legion Of Vapers.
Yihi is the chipset and hardware brand behind some of the most technically accomplished vaping devices on the market. Based in Dongguan, China, Yihi has spent over a decade developing proprietary chip technology that powers the SXmini range, one of the most respected lines of regulated mods and pod kits in the vaping world. Where most brands rely on third-party chips, Yihi designs and manufactures their own, giving them precise control over firing speed, temperature management and coil protection in ways generic chipsets simply cannot match. Through our own testing and daily use, we’ve found vapers consistently choose Yihi-powered devices for one reason: they’re reliable in a way that holds up over months, not just the first week. Whether you’re after the joystick-controlled precision of the SXmini G Class mod or the compact simplicity of the Puremax pod range, we stock the full authentic UK-supplied Yihi lineup right here.

Yihi built their reputation on one thing: doing the chipset properly. Their proprietary SX-series processors, including the SX550J found in the G Class mods and the PURE chip system in the Puremax pod range, handle coil temperature, firing accuracy and power delivery at a level that puts them ahead of the off-the-shelf chips most budget and mid-range brands use.
What sets Yihi apart is that they control the full technology stack, from the chip that fires the coil to the firmware that runs the screen. Fewer compromises, more consistent performance in the hand. That’s not a marketing claim, it’s the reason experienced vapers keep coming back to the SXmini lineup when cheaper options have let them down.
The SX550J and SX485J chipsets are purpose-built, not adapted from generic regulated mod chips. That distinction matters when you’re spending serious money on a setup and want the tech to back it up.
Yihi Vape and Pod Kits
The Puremax pod series is where most vapers meet Yihi for the first time. The Puremax and Puremax V2 use auto-draw and button-fire respectively, with the V2 adding a full colour screen and SX Link adapter customisation. The Puremax Q brings a boxier skeleton-style chassis with the same PURE chip at its core. All three are compact, fast-charging and built around the PX pod system, making them a strong step up from disposables without adding complexity.
Yihi Mods
The SXmini G Class and G Class V2 are the flagship mods, powered by the SX550J chipset with dual 18650 or 21700 battery support. The joystick navigation replaces the standard button array with a single intuitive controller, and the precision of the temperature control and wattage modes goes well beyond what most regulated mods offer at this price point. The SL Class offers a single-battery option for vapers who want the same chipset quality in a lighter, more portable form.
Yihi Tanks
SXmini tanks are engineered to work alongside the G Class and SL Class mods as complete systems. Airflow is tuned for a tighter, more flavour-focused draw rather than maximum cloud production, which suits the brand’s MTL-to-restricted DTL positioning. Build quality and thread precision reflect the same standards as the mods themselves.
Yihi Coils and Pods
The PX pod range covers three variants for different liquid types. Blue PX pods are designed for thinner 50/50 nic salts, standard black Puremax pods handle higher VG liquids, and the PX Pro pods add a locking juice well to prevent leaks alongside the liquid detection system that protects the coil during low-liquid vaping. Pod lifespan sits at around one to two weeks depending on your juice sweetener level and how heavily you vape.
Yihi Accessories and Spare Parts
We stock SXmini accessories including the SX Link adapter for Puremax V2 screen customisation, replacement battery doors for the G Class V2, spare pods across the PX range, and replacement glass and O-rings where available. Keeping a spare pod or two on hand is worth it, especially if you switch between liquid types regularly.

Yihi products make it onto our shelves because they earn it. We’ve run the Puremax kits as daily carries, pushed the G Class through extended sessions on high-wattage builds, and found the PURE chip system genuinely holds up where cheaper alternatives fall off. Over a week of continuous use, the liquid detection feature on the PX Pro pods does what it claims, cutting power before a dry hit develops rather than after.
The hardware is built to last, the chipset does what it claims, and the pod system is one of the few at this price point we’d recommend to both a switcher and an experienced vaper without qualification.
If you’re going to spend serious money on a vape setup, Yihi is one of the few brands where the price reflects what you actually get.
The right Yihi device depends on how you vape, what liquid you use and how much control you want over your settings. Here’s a straightforward breakdown.
The Puremax Q is the most approachable entry point. It’s button-operated, compact and works well straight out of the box with nic salts or 50/50 liquids. Moving from disposables or cigarettes and want something that requires minimal setup? This is the one to start with. Pair it with the Blue PX pods and a 50/50 nic salt at up to 20 mg/ml for the closest feel to what you’re used to.
The Puremax V2 gives you a little more, specifically a full colour screen and the option to customise the display via the SX Link adapter. Performance is the same PURE chip reliability, but the V2 suits vapers who like to see their data and want more control over the look and feel of the device.
Running 70VG shortfills or above? Use the standard black Puremax pods rather than the Blue pods. The Blue pods are optimised for thinner liquids and will struggle to wick a high VG juice properly, which is where most flavour and dry hit issues with this system come from. Getting that pod choice right makes a significant difference to the experience.
The SXmini G Class V2 is the right choice here. Dual battery support with 18650 or 21700 cells, the SX550J chipset, full temperature control and wattage modes, and the joystick navigation system give you the kind of precision and build quality that justifies the price over time. It’s built for vapers who want to tune their setup and run tanks or rebuildables, not those looking for a grab-and-go solution.
The SL Class sits between the Puremax range and the G Class. One battery keeps it lighter and more portable, but you still get SXmini chipset quality and the same navigation system. A solid middle ground if you want mod-level performance without carrying dual 18650s.
Every Yihi and SXmini product we sell comes through authorised UK distributors only. There is a real problem with counterfeit and grey-market hardware in the UK vape market, especially at the higher price points where Yihi sits. Buying from us means you’re getting the real chipset, the real warranty, and a product that has passed through a legitimate supply chain from source to shelf.
We keep our Yihi pricing competitive and update our deals regularly. Check the multi-buy and clearance sections for discounted SXmini accessories and pods, and keep an eye on our sale pages for kit deals worth picking up.
Orders are dispatched quickly with free UK delivery available over the qualifying threshold. Most orders placed before the daily cutoff go out the same day, so you’re not waiting around for gear you’ve already decided on.
Our team are active vapers who use this gear themselves. We’ve handled the G Class, run the Puremax kits and worked through the pod compatibility questions that come up regularly. If you’re not sure which pod suits your liquid or which Yihi device fits your style, get in touch and we’ll give you a straight answer.
Explore our answers to some frequently asked questions.
Yihi is the chipset and technology company. SXmini is the hardware brand that builds devices around Yihi’s proprietary SX-series chips. When you buy an SXmini product, you’re getting a device built on Yihi’s own in-house technology rather than a licensed third-party chipset. The two names are closely linked but refer to different parts of the same ecosystem.
The PURE chip actively monitors coil temperature during each draw and adjusts power delivery to keep it consistent. In practical terms, this reduces dry hits, extends pod life and keeps flavour cleaner over time compared to devices that fire at a fixed wattage and leave the coil to manage itself.
Use Blue PX pods for 50/50 nic salts and thinner liquids. Use standard black Puremax pods for high VG liquids (70VG and above). Use PX Pro pods if you want the added liquid detection and leak protection, regardless of liquid type. Choosing the wrong pod for your VG ratio is the most common cause of dry hits on this system.
Around one to two weeks in most cases. Sweetened dessert liquids burn through coils faster than fruit or menthol options, so a week on a sweet juice is normal. Switching to a less sweetened liquid can extend pod life noticeably, and the PURE chip’s temperature management helps too.
Yes, particularly the Puremax Q. It’s compact, easy to use and delivers consistent nicotine satisfaction when paired with a 50/50 nic salt at up to 20 mg/ml. The running cost over disposables is minimal once you account for pod replacements versus buying a new disposable every day or two.
The G Class V2 supports both 18650 and 21700 cells. For the best balance of power and run time, 21700 cells are the stronger choice. Our 18650 vs 21700 battery guide breaks down the differences if you’re not sure which to go with.
