The perfect cord that we needed to plug our portable light into the plug on the outside of our camper. Love that its extra long too!

—— Adarondax

The Y Splitter Power Cord is great for efficient power distribution. this splitter cord provides a reliable and versatile solution for extension and other power needs. With 250V/10A capacity, it's a great choice for power connections in various setups. I would recommend it

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
