For inexpensive USB power, Anker has been my go-to. They also do the Qualcomm quick charge with many of their products. Related, I liked their stuff so much, and was so impressed when ripping apart one to use for lots of 5V amps, that I bought their LED desk lamp (Lumos A2) which I&#x27;ve been very satisfied with. They also have the E1 out now, which is more powerful as lumens go.<p>Edit: tear down of the charger I like by Anker (thanks binman): <a href="http:&#x2F;&#x2F;lygte-info.dk&#x2F;review&#x2F;USBpower%20Anker%2040W%205-port%2071AN7105%20UK.html" rel="nofollow">http:&#x2F;&#x2F;lygte-info.dk&#x2F;review&#x2F;USBpower%20Anker%2040W%205-port%...</a>
