The Innergie USB Charger – Duo USB Charging Kit (Home) is selling at Challenger for S$50 (after 10% member’s discount is S$45). I got it from VivoCity’s Challenger.

There are 2 versions of the Duo USB Charging Kit, one is for home and the other is for car. The car’s version is selling for S$45 (after 10% member’s discount is S$40.5).
