You want a minimum voltage drop rather than the thinnest cable that is rated for 10 A, so I suggest 2.5 mm^2 flexible, >2.

Considering that there have been serious problems with the power connectors for portable computers failing and even burning up, and these are working at about 5 A maximum, I recommend choosing a low-trouble rather than a low-cost connector. -- OOO - Own Opinions Only.
