MOGA's in-development iPhone compatible gamepad may come with a built-in battery, according to reportedly leaked photos of the device posted by @evleaks.
@evleaks tweeted a picture of the gamepad attached to an iPhone, noting it was powered by a 1800mAh battery. A photo of the gamepad in the closed position was later deleted by the site, but published on MacRumors.
The controller, which @evleaks labeled as the MOGA Ace Power, also includes a traditional D-pad on the left side, buttons on the right, dual thumbsticks on the front side and triggers/bumpers on the shoulders. The design is very similar to MOGA's Pro controller designed for use with Android devices.
In June, Apple announced support for third-party gaming controllers would be a feature of iOS 7. Following the software's rollout in September, ClamCase revealed its bid into the third-party iOS gamepad market, the GameCase.
A representative for MOGA told Polygon that the company "does not respond to rumors and speculation" and cannot share more details on any plans to produce iOS controllers at the time.
Update: The Verge posted a leaked video featuring the MOGA Ace Power, which confirms the gamepad will work with the iPhone 5, 5C, 5S and fifth-generation iPod Touch. The video has since been marked as private.
