Solar Panel Connectors Compatible with M-C-4 Solar Connectors to DC Extension Cable 16AWG with DC 5.5mmx2.1mm, DC3.5x1.35mm,DC5.5x2.5mm and DC8mm Adapter for Portable Power Station Solar Generators

Purchased because different solar generators required different charging connectors: 5.5 mm for Ravpower and 8mm for Technoss solar generators. MC4 connectors/polarities matched perfectly with 100 watt Newpowa polycrystalline panel - received 85 watts at 12 noon, clear skies, April, northern California. Construction quality of connectors and cables seemed adequate for price-point. Very satisfied so far.Tip: Because polarities vary widely among different brands, it is important to verify polarities of solar panels, solar generators, and connector/cables when mixing/matching components.

I bought these cables as both backups & upgrades for any future purchases I will make modest solar system. Compared to Harbor Freight, the price was right..and, b-4 all ther price increaes take effect because of the political climate--I felt the need to get them NOW. So, kindly forgive me if I can't give you a 1st hand experience, I'm feeling gald I got them for my toolbox. Thansk for reading. Don

For the several small solar panels that I have: RED (+) is a MC4 femaleThis cable MC4 male is a BLACK wire connected to the DC 5521 center (typically +)This works for me, but connecting a RED wire to a BLACK wire is a problem.

Fair price, this solar cable allows me to go straight in to many of my rechargeable power banks with minimal connections with the correct size barrow plug came fast and as stated, would buy again or recommend. Thanks

Good

The cable connector’s we’re a good fit. The adapter helped connect my solar panels to the 8mm plug.I am satisfied.

It comes with a variety of adapters. One adapter is exactly the one to connect a Goal Zero solar charger to solar panels that use MC4 connections. It's well made, and long enough to work. I wish it was a longer cord, but it's OK.
