Description
The 3M MC4 to XT60i Solar Extension Cable is a heavy-duty, high-efficiency bridge between your solar panels and your portable power solution. Specifically designed for the modern explorer, this 12AWG cable allows you to keep your EcoFlow Portable Power Station (Delta or River series) in the shade while your solar panels soak up the sun at a distance.
Whether you are a van-lifer, an off-grid camper, or preparing for home emergencies, this cable ensures a lossless, secure power transfer from standard MC4 solar connectors to the upgraded XT60i input.
Key Features
-
Upgraded XT60i Connector: Unlike standard XT60 connectors, the XT60i is specifically designed for solar charging, allowing your power station to recognize the connection and optimize the charging current.
-
Heavy-Duty 12AWG Wire: Built with high-quality 12AWG tinned copper to minimize voltage drop and maximize power efficiency over the 3-meter (10ft) span.
-
Weatherproof & Durable: IP67 waterproof rated MC4 connectors and a high-temperature resistant PVC jacket make this cable perfect for harsh outdoor environments.
-
Plug-and-Play Simplicity: No tools required. The “Snap-and-Lock” system on the MC4 ends ensures a secure connection that won’t pull apart during high winds.

Standard cables often result in “ghost power loss” due to thin wiring or poor conductivity. By choosing our 12AWG 3M extension, you are investing in a low-resistance path that ensures every watt gathered by your panels actually reaches your battery. The extra 3-meter length provides the flexibility to park your RV or set up your tent in the shade while maintaining peak solar positioning.
