Some EX3 owner, please help

[Harlockr]

Hi there.
I accidentally mixed the cables from my EX3 and a external hard drive, and now I can't figure out which on is from the EX3 (or the HD in that case).
Both are exactly the same shape, just one is 7 amps (gray color), and the other is 10 amps (black color)

Any EX3 owner out there that could tell me please which one is the right for the camera : )

Thanks!
