Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Efficiency Power Generation: Designed to deliver 80A output at 14V, providing stable electrical power for vehicle systems, including battery charging, lighting, and auxiliary components.
  • Integrated Pump and Voltage Regulation: Features a built-in regulator for automatic voltage control and a water pump (where applicable) to enhance cooling and system efficiency.

Key features

  • 1. Robust Material Construction

    • With a corrosion-resistant metal body and heat-dissipating cooling fins, you can ensure long-term durability and efficient thermal management. Compared to plastic-bodied alternators, this design offers superior heat resistance and structural integrity for harsh automotive environments.*

  • 2. Integrated Smart Design

    • With an integrated water pump and built-in voltage regulator, you can achieve seamless installation and automatic voltage regulation without external components. This simplifies setup compared to standalone systems requiring separate regulators or pumps.*

  • 3. High-Output Performance

    • With an 80A output capacity, you can power all vehicle electrical systems reliably, even under heavy loads. This provides ~25% higher output than standard 60A alternators in similar vehicles, ensuring sustained performance for accessories and battery charging.*

  • 4. Tailored Vehicle Compatibility

    • With precise fitment for Kia models like Pregio, ReTona, and Pride (2000-2007), you can ensure optimal performance and compatibility. This tailored design outperforms generic alternators in maintaining electrical stability for these specific vehicles.*

  • 5. Automotive-Grade Compliance

    • With 14V output compliant with automotive electrical system standards, you can guarantee safe and reliable integration. This meets industry requirements, unlike non-compliant aftermarket parts that may risk system malfunctions.*

Supplier's note

  1. Breakthrough Features:

    • Advanced Cooling: The Pro Model’s liquid-cooled system reduces operating temperature by 30% compared to industry standards, enabling stable performance in harsh environments.
    • Precision Voltage Control: The Advanced Model’s ±0.8V regulation minimizes battery strain, extending battery life by up to 25%.
    • Material Reinforcement: All versions use aluminum alloy cores, ensuring 20% lighter weight than traditional steel alternators without sacrificing durability.

  2. Version Selection Guidance:

    • Base Model: Ideal for standard Kia vehicles (e.g., Pride 1998–2000) with minimal aftermarket modifications.
    • Advanced Model: Recommended for high-demand applications like towing or vehicles with added LED lighting systems.
    • Pro Model: Best suited for extreme conditions (e.g., off-roading or prolonged engine idling) where thermal stability and peak performance are critical.

With the Pro Model’s triple-layer heat shielding, you can safely power heavy-duty accessories like winches or inverters. Pair its 110A output with the built-in regulator to ensure consistent voltage delivery, even during sudden load spikes.
