SX Mini
SX Mini is the device brand built around YiHi's own SX series chipsets, which is what separates it from most of the hardware market. Where many manufacturers buy a generic board in, SX Mini devices run silicon designed in house. This collection holds 5 SX Mini products covering the Puremax pod kits, the MQ Class mod and the replacement pods that keep them running. Prices run from £3.99 to £29.99.
Because the range spans pod kits and a full mod, the practical question for most buyers is consumables. Pods decide what a device costs to own, so it is worth knowing which platform you are buying into.
Pods and coil compatibility
Pod compatibility is the single most useful thing to get right here. The SX Mini Puremax PX Replacement Pods at £3.99 are the consumable for the Puremax PX platform. They are not a universal fit, so a pod bought for one Puremax generation will not necessarily seat in another. Check the exact model name on your device, not just the family name, before ordering replacements.
Pods with an integrated coil are replaced whole, so a new coil arrives every time flavour drops off. Pods built to take a separate coil head cost less to run long term because you only replace the part that wears.
The SX Mini range
Puremax pod kits
The SXmini PUREMAX Pod Kit at £9.99 is the entry point. The SX Mini Puremax Q Pod Kit at £19.99 and the SX Mini Puremax 2 Pod Kit at £25.99 sit above it. Pod kits are the most straightforward format in vaping. The pod holds the e-liquid, it clips into the body magnetically and there are no threads to cross.
MQ Class mod
The SX Mini MQ Class Vape Mod at £29.99 is a mod rather than a kit, so it is the powered body on its own and you supply the tank. That suits someone who already knows which atomiser they want on top.
Coil resistance and e-liquid
Resistance decides everything about how a device behaves. A coil above 1.0 ohm is a mouth to lung coil. It runs at low wattage and wants a 50/50 PG to VG blend such as a 10ml nic salt at up to 20mg per ml. A coil below 1.0 ohm is a sub ohm coil, wanting open airflow, higher power and a high VG shortfill at 0mg to 6mg. Put a thin 50/50 liquid in a sub ohm pod and it will leak. Put a thick shortfill in a mouth to lung coil and it wicks too slowly, giving a dry hit.
Priming and coil life
Prime every new pod or coil. Wet the exposed cotton through the ports, fill the pod, then let it stand for five minutes before the first draw. Skipping that step is the most common cause of a burnt coil on day one. Expect one to two weeks from a coil. Sweet dessert and candy flavours contain sucralose that caramelises onto it and cuts that short.
Buying rules and support
Vaping products are sold to adults aged 18 and over. Nicotine e-liquid in the UK is capped at 20mg per ml in bottles of 10ml or less, pods supplied with nicotine liquid are capped at 2ml and single use vapes have been prohibited from sale since 1 June 2025. UK delivery is free on orders over £20 and the team can check pod compatibility on 07827 210361 between 8.30am and 4.00pm.
SX Mini questions answered
What is SX Mini known for?
SX Mini devices are built around YiHi's own SX series chipsets rather than a bought in generic board. That focus on the chipset is the brand's calling card and it is why the range appeals to vapers who want precise control over how power is delivered.
Which pods fit my SX Mini device?
Pods are made for a specific model rather than the whole family. Puremax PX Replacement Pods are made for the PX platform and will not necessarily seat in a different Puremax generation. Check the exact model name printed on your device before ordering. Buying a spare pack alongside the kit means you are never caught short.
Is the MQ Class a kit or a mod?
It is a mod, which means you get the powered body on its own with no tank included. You choose the atomiser that goes on top. That suits an experienced vaper who already knows which tank they want. If you want everything in one box, one of the Puremax pod kits is the better starting point.
What e-liquid should I use?
Let the coil resistance decide. Coils above 1.0 ohm are mouth to lung coils and want a 50/50 blend such as a 10ml nic salt at up to 20mg per ml. Coils below 1.0 ohm are sub ohm coils and want a high VG shortfill at 0mg to 6mg. Using the wrong one causes leaking at one end and dry hits at the other.
How long does a pod or coil last?
One to two weeks is typical. Sweet dessert and candy e-liquids shorten that noticeably because the sucralose in them caramelises onto the coil. Flavour turning dull, thinner vapour and a harsh edge on the draw are the signs it is time to change. Priming properly extends coil life more than anything else you can do.
Are SX Mini devices suitable for beginners?
The Puremax pod kits are approachable enough for someone fairly new to vaping, since the pod clips in and there is nothing to assemble. The MQ Class mod is not a first device, because it needs a tank chosen separately and rewards someone who already understands wattage and coil resistance.
