Mophie has received critical acclaim and a number of awards for their portable batteries for mobile devices. They have previously worked with the likes of Valentino on a limited edition battery pack and now the mobile accessories maker teams up with New York City streetwear icon Supreme on a compact charge battery keychain for Apple devices with lightning connection. The simple design features the well-known and much loved red and white Supreme logo printed across the front and back. The keyring pulls out to reveal a lightning connector to easily charge your iPhones and iPads when you're on-the-go. The Supreme x Mophie Power Reserve Keychain is part of the recently unveiled Supreme Spring/Summer 2015 collection. Take a look and keep an eye out for release information.
