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.
RJ45 Male to SAE Connector – Compact plug-to-wire solution
Step-Up Power Conversion – Boosts 5V to 9V / 12V DC (optional versions)
High Compatibility – Works with routers, PoE injectors, solar panels
Flexible and Durable – PVC jacket, pure copper wire core
Polarity Marked – SAE interface with reverse-polarity protection (optional)
PoE Power to DC Systems
Charging Lithium Battery Packs via SAE
Solar Panel Power Output Adapter
RV / Car DC Device Connection
DIY Electronics / IoT Projects
Confirm input voltage is stable (5V recommended)
