Both versions of Apple's new Lightning to 30-pin adaptor saw stockouts within 30 minutes of Apple initiating pre-orders on Friday, with estimated ship-by dates bumped back into next month.
Currently, there are two adaptor models available, a $39 version with a 0.2-meter cable and a $29 unit that resembles an oversized 30-pin plug.
Apple unveiled the smaller 9-pin Lightning connector alongside the iPhone 5 at a special event on Wednesday, with the new plug said to be a necessity in building thinner iDevices. The proprietary part is 80 percent smaller than the legacy 30-pin connector it replaces, is all-digital and can be plugged into compatible devices in any orientation.
Besides the iPhone 5, the new iPod touch and iPod nano also use the newly introduced standard.
The adaptors may be available in brick-and-mortar Apple Stores, though the stock allotted to each location is not known.
