This listing is for a prewired pair of RCY type (aka JST RCY) wire-to-wire connectors, 2 pole.
One male plug, one female socket, wire length 15-20cm (depends on batch, ask if you care).
RCY Connectors have a 2.50mm pin pitch and can carry about 3A Maximum officially (I think it's fair to say that people often push this quite a bit further, but that's something you'd need to test carefully, especially with china-sourced items such as this!)
Each "item" you buy gets you a pack containing:
1 of male plug prewrired
1 of female socket prewired
