How ever your solar panel connection show on its output, is what you go by on the end of this cable 5521 port. Ignore markings and color of cables.My power station 5521 input is positive on the center, negative on the outer.My Male out on solar is positive.This cable female is the 5521 inner. ( continuity checked ).The picture shows the female is the center of 5521 inner.You need to know this info first before buying the wrong cable.. because in MY setup, the 5521 center has to be positive... this cable works.I don't know if it is a ' standard ' that the SOLAR male output is positive. But it is in my application.When I look at the cable markings and color of wire it makes you disbelieve and check with contunity .Checking female to center of 5521 is a GOChecking female to outter of 5521 is nil.Female is center of 5521 on this cable.So it isn't right, and it isn't wrong.. it is what your test results wants.. Ignore - + on the black ends.. ignore red or black wires.. find out what is positive out the solar panel and match what is positive on the 5521 on the item your working with ( power station for me ).OK??

These were exactly the cables I was looking for. They fit my solar panel perfectly, and plugged directly into my big batter packs. The batteries charged in a few hours, so I know these cables work.

It works.

The polars are reversed but, it charged the Puleida Pu600 at 86 watts with a 100 watt panel so...works great.

Great product

I ordered this product to use for my equipment. It can be brought everywhere. My favorite thing about this product is that it can be easy to put away.

I got a portable battery so bought this solar to battery cable to charge my battery from solar. It’s working pretty well but I had to switch positive and negative wires to test which way works. I am not sure if I say it right or not but I hope the cable wires are thicker.

Can be a bit loose other than that works well another one like it I but

Cable and adaptors were just as described. Works well.

Perfect als je meerdere zonnepanelen wil verbinden

Eine SinKeu Tragbare Powerstation wird damit super aufgeladen,Dranschalten und aufladen

Well, my error buying this, was the MC4 connectors are reversed for what I need to attach this to my eb70. Waited for weeks to find out. Thats what happens when you dont know what you're doing. You order wrong item.

Kabel funktioniert top, Adapterstecker erfüllen die Funktion. Alles gut
