    Description


    Features:
    1. Adopt synchronous rectification technology, which greatly reduces the rectification loss at the output end of the switching power supply, thereby improving the conversion rate and reducing the heat generation of the current itself
    2. It adopts high thermal conductivity organic silica gel and potting waterproof technology, which is compatible with multi-level protection functions, and has functions such as shock resistance, waterproof, dustproof, and moisture-proof.
    3. Adopt aluminum alloy shell design, which is safer, has better heat dissipation effect and more stable performance
    4. Small size, does not take up space
    5. Using 99.99% oxygen-free copper core wire, lower resistance, better conductivity, low carbon and power saving
    6. Using SMT technology, the product is small in size, reducing electromagnetic and radio frequency interference, and the solder joint defect rate is low
    7. Good compatibility and wide application range

    Must Read before ordering. Where trust drives commerce

    We believe in honesty over marketing.
    Some items may not have customer reviews yet, but the reviews you do see are 100% authentic, verified, and managed by Judge.me, an independent review partner trusted worldwide.

    Instead of posting fake reviews, we prefer to show only what is real — even if that means some products are still waiting for their first review.
