Review on 🔌 yarachel 25Pairs / 50PCS Solar Connectors - IP67 Waterproof Male & Female Connector Kit (25 Pairs Solar connectors) by Adam Hogan

Happy with it. Plugs and contacts are excellent, good quality. Once I had the pins in the connector, I found that it was easier to unscrew the grip part if I pushed the rubber grommet into the connector as far as possible before assembly, unless the grip cap can come loose when you start stripping the jump threads . Note: I purchased Revain's Renogy assembly tool and it does not fit these connectors. The Renogy tool is too large for the handle end of the connector. The tools fit the male and male ends so you can hold that end with the tool and then use pliers to tighten the side of the handle. The Renogy tool also works to disconnect MC4 connectors once they are connected. It has a pair of pins that snap into the connector so they can be pulled apart. I also bought a Revain connector crimping tool and it's a quality part for $16 too. I used medium 5mm? Crimping area on the crimping tool. This provided a good grip. Hope that helps.
