Used these on an RV solar install
Used this on my RV to install some solar panels. I bought it because it was the cheapest option, and I was pretty happy with it! I did some testing with a voltimeter and was getting minimal voltage drop from my 300-watt panel over a 20+ feet run of this cable. Also, I pulled off a couple of the connectors to check it out, and I was impressed at how well they were secured. Seems pretty quality, which is impressive for the price! I ended up buying another set of cables, and I would recommend these because they work well. Plenty flexible and this is a nice length, I will definitely buy again on my next setup

Works.
Not as easy to unplug as OEM from Echo Flow, but it works fine. I like it and the price.

Works as expected
Got this extension wire with preinstalled mc4 connectors on either ends. Works as expected. No issues connecting and disconnecting the lines. Minus one star as it would have been better if the red and black cords were fused versus separated. No point having the lines separated as it just makes for more of a tangled mess. Also be aware that the wires are pretty stiff (not very pliable). Easy fix was to zip tie portions along the 20ft to keep the two cables together. Would buy again if needed

The length I needed
This set of solar extension cables allowed me to set up a solar panel I hadn’t been able to use a good distance from my bedroom window so I can get my TV, laptop, phone, and a lamp all running off of it. It was just the right length to get the panel into a sunny spot; my bedroom is on a shady corner of the house. The MC4 connectors, which can sometimes be tricky, work fine.

Works well
Easy to use and do what they're supposed to. Good quality. Bought them so we could place our portable solar panels further from the campervan.
