History.
Prong was founded in 2011, and first gained traction through its fully funded Kickstarter campaign with the production of the PocketPlug. The company has since introduced the Prong PWR Case, a removable battery case with integrated prongs.
Prong introduced its flagship product, the PocketPlug, at the Consumer Electronics Show in January 2013 after its 2012 Kickstarter campaign. It was first reviewed by "The Washington Post", citing that they enjoyed the product, although adding the critique that a battery pack was needed and the product had limited usability during charging. The "New York Times" gave a similar review.
Peritus Power in the UK developed the iPhone 6 cases, although iPhone 7,8 standard and Plus cases were planned in addition to Universal Android cases. Prong ceased trading in 2017.
