TLD Electronics is a China-based DC power cable manufacturer and supplier providing DC-to-DC power cables for satellite communication equipment, vehicle systems, battery-powered devices, off-grid installations and industrial applications.
Our DC Power Cable range covers different conductor sizes, cable lengths, connector configurations and jacket materials for indoor and outdoor use. Standard and custom cable assemblies are available for distributors, system integrators and project-based applications.
For Starlink-related applications, cable configuration should be matched to the specific terminal model, power source, connector, voltage and current requirements.
A DC power cable transfers electrical power from a DC source to compatible equipment through a specified cable and connector configuration. Unlike AC power cables, this cables are commonly used with batteries, vehicles, solar systems, portable power stations and DC-powered communication equipment.
TLD Electronics supplies DC-to-DC power cable assemblies for applications including Starlink terminals, RV and vehicle systems, battery-powered equipment and off-grid communication installations.
For Starlink Mini, the official specification lists a 12–48V DC input range and 60W maximum input power. The optional USB-C power configuration requires a 100W USB-PD power source with 20V/5A minimum. Cable selection should therefore be based on the actual terminal and power configuration rather than voltage alone.
Custom DC-to-DC cable assemblies for specified Starlink terminals, with options for cable length, conductor size, connector configuration and jacket construction.
Designed for compatible 12V and 24V vehicle, RV and auxiliary battery systems. Cable specifications can be selected according to the connected equipment's current requirements.
Suitable for battery packs, solar-supported equipment and off-grid communication systems where reliable DC power transmission is required.
Available with weather-resistant cable jackets and sealed connector constructions for outdoor, camping, mobile and exposed installations.
OEM cable assemblies can be produced according to drawings, samples or specified electrical and mechanical requirements.

The cable must be suitable for the output voltage of the power source and the input range of the connected equipment. A cable should not be selected based on connector size alone.
Current capacity depends on conductor size, cable length, conductor material, insulation and operating conditions. The selected cable should be matched to the actual load.
Longer cables have higher electrical resistance and may experience greater voltage drop under load. Conductor gauge and cable length should therefore be evaluated together.
Connector dimensions, polarity, locking method and sealing structure must match the target equipment. For custom Starlink-related cables, the connector specification should be verified against the applicable terminal model before production.
Indoor, outdoor, vehicle, RV, marine and off-grid installations may require different jacket materials, sealing structures and mechanical protection.
These cables can be used for specified satellite communication terminals and related DC power systems where the connector and electrical requirements are matched.
Suitable for connecting compatible communication and electronic equipment to vehicle or auxiliary battery power systems.
Used with batteries, solar power systems and other DC power sources in locations without a conventional AC supply.
Weather-resistant configurations can be selected for outdoor communication, camping and marine-related installations.
Customized cable assemblies can be produced for instruments, control equipment and other DC-powered industrial devices.
