Anyone try something like the UT Starcom YC150B cable?
Information around says it maxes at 1A (1000 mA), but that may just be adding the specs for 2-USB ports (500mA) and not really a limitation of the cable itself.

It's cheap, but I already have enough cables laying around that don't do what I want...
Example: Griffin eXport cable for use on in-flight entertainment systems
