PQI's newest creation combines the functionality of a USB portable hard drive with a battery-powered NAS server supporting both 802.11n WLAN and Ethernet; and an AP (access point), that relays your wired Internet connection to multiple WiFi-enabled devices. The Air Bank 6W31 line of devices ship in black and white body panel color options, and storage capacities of 500 GB and 1 TB. Measuring 77 x 135 20.5 mm (WxDxH), the devices weigh around 250 g, which makes them as big and heavy as most wireless hard drives. They use lithium polymer batteries that can keep them going for 5 hours on a full charge. Slated for March 22, with availability beginning in Japan, the 500 GB model is priced at 15,800¥ (US $165), and the 1 TB model at 19,800¥ ($206).
