The 2-pin quick connectors are well made and heavy duty. Fitment was good and compatible with similar connectors on my equipment. I used the connectors to wire a battery “generator” to an inverter for an AC current supply while camping. The quick connectors were used to plug in the inverter and connect to a battery charger. The battery charger uses the same style connector so it is easy to unplug the inverter and plug in the charger with no tools required. Works great! Good value.
