Review on ⚡ PowMr 48PCS M-C-4 IP67 Solar Connectors - Male/Female Solar Connectors (24 Pairs) by Sergio Guardado

I bought these for a small standalone system which I helped use with older panels that didn't have standard MC4 connectors. These plugs work well and are difficult to tell apart from high-end plugs, but there is a slight difference in the plastic composite material, which has a slightly gray tint. I wouldn't use them on more expensive rigs, although they will do for most portable or hobbyist rigs. For the price they are great.
