    Product Details

    10–36V to Stable 57V Output

    Converts 10–36V DC input into a stable 57V output, engineered for Starlink Gen 2 / Gen 3 (V3) router power requirements. Output rating: DC 57V 4.5A Max 256.5W. Cable run is 1M / 39 in.

    4.5A / 256.5W Delivery

    Rated for 57V at up to 4.5A (256.5W max), with 14AWG heavy-duty input wiring for safe current transfer. Rated for DC 10V – 36V input. Connection standard: Barrel Jack Male with Waterproof Gasket.

    Plug-and-Play Cable Kit

    Includes a 39-inch (1 m) power cable with a waterproof DC gasket for direct, hassle-free connection to the router. Built with Over-Voltage, Short-Circuit, Overheat protection.

    All-Weather Protection

    IP-rated shockproof, dustproof and waterproof construction keeps the converter reliable in extreme outdoor and marine environments. The waterproof DC gasket seals the 5.5×2.1mm barrel connection, while built-in over-voltage, short-circuit and overheat protection — backed by 14AWG input wiring — guard the Starlink Gen 2/3 router during heavy use.

    Aluminum Housing Thermal Design

    The rugged aluminum alloy housing dissipates heat efficiently, preventing performance throttling during peak data usage. Converting 10–36V DC input to a stable 57V output (up to 4.5A / 256.5W), the converter feeds Starlink Gen 2/3 routers with a 1M (39 in) output cable, waterproof gasket and full over-voltage, short-circuit and overheat safeguards.
