Hi,

I purchased a LED strip light kit. It came with the controller and power bank.

Unfortunately I am struggling trying to figure out how to power them on. The LED strips have two wires, a red and a black. One side of the controller has four little slots where I think the red and black wires are supposed to connect (but might be wrong). If they are supposed to connect there, I don't know which of the four they should be connecting to.

And then for the power, the power bank has a normal round looking connector (a lot like a laptop charger connector), but the controller doesn't have a connector for it. The power bank came with this small adapter thing with the green block on it that looks similar to another green thing on the controller but I have no idea how any of it is supposed to join up.

Any help or advice would be hugely appreciated.

White box/Green block w two screws: red on v+ black on v-.

Barrel jack with the two screws is likely an adaptor.

What is on the other end of the wires shown in second picture? Are the bare/soldered as well?

Can you take a photo or two of everything overall? Feel like I'm missing a few things.

EDIT - I think wires other end is the male barrel jack. barreljack w wires goes to power bank. Red to v+ on block in photo 1. Black in v- on green block in photo 1. Where is LED strip? Need to see its connector/termination.
