So there's this growing trend in laptops that only offer one port...we can solve that problem. With the PowerPack 20000, you get 2 devices in 1. Not only a portable charger, the PowerPack 20000 also has a USB Hub mode (USB 2.0 compliant) that delivers data transfer over its USB ports. Need to connect a mouse to your laptop? Plug it into the PowerPack 20000. Need to access an external flash drive? Plug it in. Need to connect a gaming controller? Plug it in. In addition, the USB Hub mode is perfect for powering your smaller devices that will require a smaller charging current.
