Got the Lifetrons – High Tech Multi-Tool Adaptor (Lightning Edition) when I was on the plane (Thai Airways) for US$69 (S$87). It is expensive, but I don’t think it is overpriced.
The High Tech Multi-Tool Adaptor is like a Swiss Army knife for gadget. It has 3 cable heads (Mini USB, Micro USB & Lightning) for syncing and charging, a SIM card holder and a phone stand.
