Supplier's note

  1. Key Technical Breakthroughs:

    • Ferrite Core Design: Enables high-frequency operation (up to 100 kHz), reducing size and heat compared to traditional transformers.
    • Twisted Terminals: Cut electromagnetic interference by 30%, ensuring stable performance in crowded electronic circuits.
    • Modular Construction: Allows easy adaptation for custom voltage ratios (e.g., 5V to 9V) without redesigning the entire assembly.

  2. Version Selection Guide:

    • Base Model: Best for standard mobile chargers (e.g., 5W-15W) where cost efficiency is critical.
    • Advanced Model: Ideal for mid-range devices (e.g., 20W wireless chargers) needing improved efficiency and reliability.
    • Pro Model: Targets high-power applications (e.g., 30W fast chargers) with its 99% efficiency and nanocrystalline core, which handles thermal stress 2x better than industry benchmarks.

*Pro Model dimensions slightly increase to accommodate advanced core materials.
