I took the plunge and went with a new Nexus 5X. This means I need to change my existing stock of micro-USB cables to USB-C. However given the proliferation of micro-USB I'd prefer to just buy an adapter so I can have the option to charge with either plug as I have external batteries, etc. that still will need micro-USB.

After much trial and error I've settled on MediaBridge micro-USB cables (available at Amazon) as being both reasonably priced and good in terms of secure connection fit and speedy charging so if possible I'd like to continue using those cables.

Does anyone have a good lead on a decent charging/data micro-USB to USB-C adapter?
