Streamliner is an elegant battery with 6,000 mAh capacity. Its shape was inspired by sports cars, hidden spoilers and technological innovations. The aluminium casing is free of pushbuttons and is therefore completely smooth in appearance. It is also dust- and waterproof and comes with an anti-fingerprint protection. The battery has two USB outputs that are automatically recognised by iPhones and iPads. A further feature is a Micro-SD card slot, which turns the battery into an external hard drive.
