Testing USB charging ports

Other Parts Discussed in Thread: TPS2543, TPS2546

We are carrying out product testing for the Lighting Global program (www.lightingglobal.org). As part of this testing, we will be testing USB charging ports that are integrated in off-grid solar home system products available on the market to see what phone and tablet devices are supported and the maximum charge currents the USB ports are able to provide. For example, we want to know if a product's USB charging ports support USB Battery Charging (BC 1.2), Apple iPad/iPhone charging to 1A and 2A, Samsung tablet charging to 2A, etc. Can someone at TI, or otherwise, please advise how the TI TPS2543 is tested to ensure it can support all of these multiple charging modes of different phones and tablets? Is there a test charging device available for instance, or is it simply a matter of buying many phone and tablet devices and testing with them? Thanks!
