I have a submersible pump with a connector to the DC adapter. The connector is rectangular 2-pin. There's a notch so it can only be inserted one way, pins are 7mm apart, about 8mm long. Female connector width is about 14mm. I see the female end advertised as a 'car cooler' plug (e.g. https://www.banggood.com/2M-12V-DC-...ble-Plug-Wire-p-1030812.html?cur_warehouse=CN) I want the male connector (see photos below, the connector is embedded into the DC adapter) to put on the end of a new DC adapter, or later, other bits to power it from solar. The current DC adapter gets crazy hot and doesn't fill me with confidence. Hoping I can find it and order it from element14 or RS Online. Click to view full size! Click to view full size!

I don't need a battery; just if there's sufficient sunlight then it works, and if there's not, then it doesn't. Since no battery, I'm guessing I don't need a charge controller, so pretty much any 12v solar panel > 11w or so should be fine? Thanks!
