Recently a leaked image of brand new USB power adapter surfaced on Weibo. The USB power adapter is much similar in shape and size to the Apple’s Australian power adapter with the only difference being the plug standard. It’s quite possible this is iPhone 6’s new power adapter for US since it has plug standards for U.S.
The corners of the power adapter are rounded and it has smooth grooves on both sides to hold the charger for plugging in and out. The picture doesn’t have a good resolution but it seems the other side has grip design for similar purpose.
In addition to a new power adapter, a new lighting cable is also expected to be released that will have a reversible USB at one end.
