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.

 Key Features

• 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)

Compatible Applications

•  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

 Usage Notes

• Confirm input voltage is stable (5V recommended)

• Do not exceed rated current load to avoid overheating

• For indoor or protected environment use

• Not designed for Ethernet data transmission – power only

• Use correct polarity at SAE output end to protect devices
