YiHi SXmini SL Class V2 Box Mod

YiHi SXmini SL Class V2 Box Mod

The YiHi SXmini SL Class V2 Box Mod is a premium single-battery vape mod powered by the advanced YiHi SX730J chipset. Delivering an adjustable output of 5-100W, it combines Variable Wattage, Variable Voltage, Temperature Control and custom power curves within a compact, ergonomic design.

Compatible with a single 18650, 20700 or 21700 vape battery, the SXmini SL Class V2 allows you to balance portability, power delivery and battery life according to your preferred vaping setup.

Please note: a vape battery and tank are not included.

Advanced YiHi SX730J Chipset

At the heart of the SXmini SL Class V2 is the YiHi SX730J chipset. Designed for experienced vapers who value accurate and customisable power delivery, the chipset provides a responsive output and several ways to adjust the warmth and intensity of each draw.

Available operating settings include:

• Variable Wattage mode
• Variable Voltage mode
• Constant Temperature Control
• Dynamic Temperature Control
• Soft, Neutral and Strong power presets
• SXi-EQ1, SXi-EQ2 and SXi-EQ3 custom power curves

Variable Wattage mode allows the output to be adjusted between 5W and 100W, while Variable Voltage mode provides direct control over the voltage delivered to the connected coil.

The Soft, Neutral and Strong presets alter how quickly power is delivered at the beginning of each draw. Soft provides a gentler ramp-up, Neutral delivers a balanced output, and Strong provides a more immediate initial boost.

The three SXi-EQ profiles provide further control over the power curve, making the mod particularly suitable for rebuildable atomisers and users who prefer to fine-tune their vaping experience.

Single 18650, 20700 or 21700 Battery

The YiHi SXmini SL Class V2 is powered by one removable vape battery and supports three commonly used battery formats:

• 1 x 18650 battery with the supplied adaptor
• 1 x 20700 battery
• 1 x 21700 battery

A compatible 21700 battery will generally provide the best balance between battery capacity and performance, particularly when vaping at higher wattages.

The included 18650 adaptor also allows the device to be used with compatible 18650 batteries, which may be more convenient for users who already own this battery size.

Battery life will vary according to:

• Battery capacity
• Selected wattage or voltage
• Coil resistance
• Length and frequency of each draw
• Selected power or Temperature Control settings

A battery is not included. Browse our range of vape batteries to find a suitable option.

Adjustable 5-100W Output

With an adjustable output range of 5-100W, the SXmini SL Class V2 supports a wide selection of compatible vape tanks and atomisers.

Lower wattages can be used with suitable mouth-to-lung and restricted direct-to-lung tanks, while higher outputs are suitable for compatible sub-ohm tanks, RTAs and RDAs designed for direct-to-lung vaping.

Always check the recommended wattage range of the coil installed in your tank before vaping.

The device monitors the connected atomiser and incorporates multiple built-in protection features to support consistent operation.

Variable Voltage Mode

Variable Voltage mode allows you to adjust the voltage supplied to the connected coil directly rather than selecting a wattage.

This gives experienced users another way to control the strength, warmth and speed of the power delivery. Always begin at a lower setting and increase gradually while remaining within the safe operating range of the installed coil.

Constant and Dynamic Temperature Control

The SX730J chipset offers both Constant and Dynamic Temperature Control settings for experienced users with compatible coil materials.

Constant Temperature Control aims to maintain the selected temperature throughout the draw.

Dynamic Temperature Control allows the temperature behaviour to change over the course of the draw, providing greater control over heat delivery and flavour.

Compatible Temperature Control materials include:

• Stainless steel
• Nickel
• Titanium
• Custom TCR materials

When configured correctly, Temperature Control can provide a more consistent vape and help reduce the risk of overheating the wick when the tank is running low on e-liquid.

Temperature Control should only be used with compatible coil materials. The coil resistance should be read and set while the coil is at room temperature.

SXi-EQ Custom Power Curves

The SXi-EQ system allows you to create custom power curves that change how power is delivered during the draw.

Three profiles are available:

• SXi-EQ1
• SXi-EQ2
• SXi-EQ3

Each profile can be adjusted in timed stages, allowing you to begin with a stronger or softer output before increasing or reducing the power later in the draw.

This provides more control than standard wattage adjustment alone and can be particularly useful when using RTAs, RDAs and other rebuildable atomisers.

0.96-Inch IPS Colour Display

A clear 0.96-inch IPS colour screen displays essential vaping information without making the device unnecessarily bulky.

Depending on the selected operating mode, the display provides access to information including:

• Selected wattage, voltage or temperature
• Coil resistance
• Active output mode
• Battery level
• Puff information
• Power-curve settings
• Device settings

The mod is operated using the firing button and responsive joystick control, providing straightforward access to its menus and adjustment settings.

Tank and Atomiser Compatibility

The centred, spring-loaded 510 connection supports a wide selection of compatible vape tanks, RTAs and RDAs.

Its centred layout helps create a balanced appearance when a tank is installed, while the spring-loaded connection maintains consistent contact with compatible 510 atomisers.

Browse our range of vape tanks if you need a compatible tank to complete your setup.

The SXmini SL Class V2 is supplied as a box mod only. A compatible tank, coil, battery and e-liquid must be purchased separately.

Compact Premium Construction

Despite its advanced chipset and extensive range of settings, the SXmini SL Class V2 maintains a compact single-battery format.

Its rounded body and curved frame are designed to sit comfortably in the hand, while the threaded battery cap provides secure access to the removable battery compartment.

The device measures approximately 89.1 × 42.3 × 30.2mm, making it compact enough for everyday use while still accommodating a replaceable high-capacity battery.

USB-C Backup Charging

The USB-C connection supports onboard charging at up to 5V/1A, providing a convenient backup option when a separate battery charger is unavailable.

As the device uses a removable vape battery, we recommend using a suitable external battery charger for routine charging whenever possible.

Never leave a battery charging unattended, and do not use batteries with damaged wraps, dents, corrosion or other visible signs of damage.

The YiHi SXmini SL Class V2 is best suited to experienced vapers looking for a premium single-battery box mod with more control than a basic variable-wattage device.

It is particularly suitable for:

• Sub-ohm tank users
• RTA and RDA users
• Vapers who prefer removable batteries
• Temperature Control users
• Rebuildable atomiser enthusiasts
• Users who want adjustable power curves
• Vapers seeking premium YiHi chipset performance
• Users who prefer a compact single-battery mod

New vapers may prefer a complete vape kit with simpler controls, as the SL Class V2 requires a separately purchased tank and battery as well as an understanding of suitable coil and power settings.

Important Battery Safety Information

Use only authentic, undamaged high-drain vape batteries from a reputable manufacturer.

Ensure the selected battery is appropriate for the wattage, voltage and coil resistance being used. Never use a battery with damaged wrapping, dents, corrosion or exposed metal.

Do not carry loose batteries in a pocket or bag where they could come into contact with keys, coins or other metal objects. Spare batteries should always be stored in a suitable protective battery case.
