Sxmini MQ Plus Mod

The SXmini MQ Plus is a compact 100W single-battery box mod from YiHi, built on the SX418J chipset. It runs a single 21700, 20700 or 18650 battery and fits atomisers up to 28mm on a spring 510 connection. This is the upgrade to the original MQ Class, stepping up from 60W to 100W and adding 21700 and 20700 support.

This listing is the vape mod only. The MQ Plus pairs with any sub-ohm tank, RTA, RDA or MTL atomiser you already run,

Key Features

• 5W to 100W output from a single 21700, 20700 or 18650 battery (sold separately)
• YiHi SX418J chipset for fast firing and stable, precise power
• Wattage and temperature control modes for MTL and sub-ohm vaping
• SXi-EQ custom power curves to shape the ramp of each puff
• Adjustable Smart Boost for a faster warm-up on demand
• 0.91 inch OLED display showing your settings clearly
• 510 connection fitting atomisers up to 28mm flush
• CNC machined stainless steel and aluminium body
• USB-C 2A charging with USB firmware upgrades
• Four colours Black, Gunmetal, Gold and Silver

Compact Size, 100W Power

The MQ Plus stays pocket-friendly at 81.5mm tall while pushing up to 100W. That range suits both mouth to lung and direct to lung vaping, so it handles a tight MTL atomiser or a sub-ohm tank equally well. Output holds steady as the battery drains, so your vape stays consistent through the day.

YiHi SX418J Precision Control

The SX418J is YiHi's own chipset, built for fast firing and accurate power delivery. It reads coil resistance, temperature and battery level continuously to keep output stable on every puff. That precision is what separates a YiHi board from a generic mod at the same wattage.

Wattage and Temperature Control

Wattage mode runs the full 5 to 100W range for straightforward, everyday vaping. Temperature control caps the coil temperature to help prevent dry hits on supported wire. SXi-EQ custom curves let you shape how power ramps across each draw, and Adjustable Smart Boost adds a faster warm-up when you want it. Everything reads clearly on the 0.91 inch OLED screen.

Flexible Battery Options

The MQ Plus takes a single 21700, 20700 or 18650 battery, with an 18650 adaptor tube included. A 21700 gives the best battery life and the steadiest output at higher wattages, so it's the one to run above 60W. Batteries are sold separately, and an external charger is kinder to your battery than USB-C over the long term.
