A simple box design, square, nothing special or monstrous, to connecting AC power. 5 USB output variable amperage (2 ports at 2.1A, 1A 2-port, port to 1.3A). There I a little stressed because I have not the slightest idea of what I can plug where. The manual is minimalist. So I proceeded by trial / error and I'll let the cables (not supplied with the Multi-Charger, damage would have been nice) in the housing for not to ask myself too many questions each time. So I have a son and 5 thread behind before (ok, only 3 before, I exaggerate) where I had before I only had one and I had to swap the son. It's certainly more convenient, but all these son on the corner of the office (where there is already too much son), is not necessarily very friendly either. I would have found shorter son perhaps ... (10cm kind :))
