A new image said to be of a redesigned Apple USB power adapter has been shared by a user on Weibo (Google Translate, via Gizmobic), hinting that Apple's supposed new Lightning cable may be released alongside a new charger. The power adapter appears to be more rounded compared to Apple's current offering, and also includes grooves on each side to improve comfort while holding and inserting the accessory.
If both new products turn out to be real, it is possible that Apple could ship a new Lightning cable and new USB power adapter alongside this fall's expected lineup of new iOS devices, possibly starting with the iPhone 6 next month.
Update: As pointed out by a user in our forums, the USB adapter shown in the images carries the same design as Apple's current 5W USB Power Adapter sold in Australia. However, the prongs on the new adapter in the photo are of Type A used in the United States and many other countries, perhaps indicating that the design could be soon applied to Apple's other power adapters in different countries.
