Support Universal Charger?

view story

http://androidforums.com – I ordered and receive a Note 2 from Handtec which came with a European charger in the box (expected). Handtec also included a separate universal charger that has plugs for the US, EU and UK but I am completely confused as to how it works. It does not have a cable on it and I don't see anywhere to plug in a USB cable. At the risk of looking like a complete fool because I'm missing something obvious, does anyone know how to use this thing? (General)
