The mod delivers clean, regulated power, providing stable voltage across a wide range of coil resistances and wattage levels. Advanced temperature control modes and memory settings further expand its versatility for both casual vapers and enthusiasts seeking precise customization.

Key Output Specs:

• Maximum Wattage: 200W

• Output Modes: Wattage, Temperature Control (Ni, Ti, SS), TCR, Joule, and customizable curves

• Output Voltage: Regulated by SX550J for consistent delivery

YiHi SX550J Chipset – Industry-Leading Control and Efficiency

The SX550J chipset is renowned for its accuracy and stability. It features intelligent buck-boost circuitry, meaning power delivery remains smooth and consistent even as battery voltage drops. The chipset also provides granular control over wattage curves, temperature profiles, and soft/standard/hard ramp-up settings, allowing users to fine-tune their vaping experience in real time.

Additional chipset features:

• Memory Slots: Save multiple profiles for different tanks or vaping styles

• Temperature Range: ~212°F – 572°F (100°C – 300°C) in TC mode

• Resistance Range: Supports a wide variety of coil builds, from sub-ohm to high-resistance setups

Premium Build with Black & Golden Finish

The G Class is crafted from high-quality materials with a refined Black Golden color scheme, combining matte finishes and polished metal accents for a luxury appearance. The ergonomic body fits naturally in the hand, while the centered 510 connector accommodates atomizers up to 30mm without overhang.

Full-Color TFT IPS Display with Joystick Navigation

A TFT IPS screen displays all device information in vivid color and clarity. Unlike traditional button-operated mods, the G Class features a joystick controller, allowing intuitive navigation through menus and settings. Users can quickly adjust wattage, change modes, or modify settings without cumbersome multi-button sequences.

Display Features:

• Wattage and voltage readouts

• Coil resistance and puff counter

• Temperature settings (when in TC mode)

• Bluetooth connectivity status

• Battery life indicators for both cells

Bluetooth App Control for Seamless Customization
