Wibow Solar Connectors Parallel Solar Connector MC4 1 to 4 Y Branch Adapter 64cm/25.2in Long Cable Wire Plug＆Crimping Tool Kit for Parallel Solar Panel(M/FFFF and F/MMMM)

The package contains two sets 1 to 4 connectors M/FFFF and F/MMMM. So far the connectors work great, I have 2 panels connected and supplying my lithium battery that provides nightlights and I can also charge my phones if needed. Super easy to wire up. I have them in my little yard and the connectors sealed perfectly even after two big rain. I'm planning on taking them while camping so that I would be able to keep connected, entertained.

It works perfectly as intended and has withstood torrential downpour in San Diego over the last few days.

Perfectos trabajan muy bien

WOw great solar charger

Order arrived early. Quality product. Looks like they should last a long time. A little stiff, so no tight bends.
