I got the 15-foot L14-30 to SS2-50R extension cord to use with my generator. I personally find SS2-50 connectors to be easier to work with than L14-30 due to the handle. I also think they're a bit safer than L14, because the ground pin in the center makes contact with the target inlet BEFORE any hot blade makes electrical contact. There's really nothing I can do about the socket that's on the GENERATOR, but I can absolutely choose my preferred outlet+plug type for its entry point on my house.

The cord is ETL-certified. ETL doesn't have the public relations budget & consumer outreach of UL, but it's accepted by American insurance companies and most (if not all) building code jurisdictions in the US. Basically, UL developed the test standards, ETL applies them, and the end result for consumers is the same.

The cord conveniently includes a carrying strap and adapter ring to facilitate more secure attachment to some inlets.

It arrived quickly and everything works.

This product is very simple to program . Satisfactory service no issues for the past
2 years. Still in working fine

This charger works just like it's manufactured to work. Hooked up too solar system, great controls, works great and has alarms to tell you if charge is low or high, checks for back charge. This works just like says it will. I'd recommend this

Yes it’s an XT60i connector but the most important thing that makes it such is not connected! The center pin is left all alone by itself, so the device you’re connecting to will assume this is a traditional XT60 cable and limit the charge. In my case my EcoFlow River 2 pro assumes it is an AC or non-solar DC connection and limits the input.
Quick and easy fix if you have a soldering iron but doing so probably revokes any chance of returning if it’s faulty.

Also, look at those solder joints!!! Oxidation already? Did you dip the stuff in a tub of salt water?

Wires are decent CCA and appears to be true to AWG size.

When you specifically sell this as a solar charging cable, PLEASE connect the center pin so devices can get all the juice possible. AKA jump the center pin to neg for solar, especially since the other connectors are MC4 (specifically for solar).
