Moshi USB Cable with Lightning Connector (available in both black and white) is retailing for S$31.90 which is about S$4 more expensive than the original Apple Lightning to USB Cable. Both cables are 1m in length and both are as official as it can gets.
The feature that makes Moshi’s version more expensive than Apple’s original is the aluminium encasing. The cable head is encased in aluminium and shielded to reduce electromagnetic interference. The Moshi’s version felt different (psychological effect maybe?). It is sturdier, more premium and slightly heavier. I think this is the cable that Apple should have made!
