Product Introduction
This RJ45 to SAE Step-Up Power Cable converts low-voltage DC input from an RJ45 power source into higher-voltage DC output via SAE connector, enabling DIY or mobile systems to power 9V/12V devices from Ethernet-type ports or passive injector systems.
It's ideal for PoE-to-DC conversions, portable battery charging, small solar power setups, and powering accessories in vehicles, RVs, or remote equipment.
