As a wonderful gadget, do you focus more on its function or appearance? If you select the former, I believe you could accept the simple appearance of mini dual port USB changer, and you’ll also enjoy its convenience.
The mini dual port USB charger sizes at 36mm dia. x 47mmm, and weights 40g, and comes with two standard USB ports, which are able to charge various USB devices. The small design also makes it more convenient to use anywhere. The USB charger is available for $7 USD at USBGeek (unavailable).
