The boxy device sits just over a foot (35 centimeters) high and can run a 40-inch LCD TV for about two and a half hours or charge a smartphone 30 times, according to the company. The "Home Energy Server" will initially launch in Japan next month, with a target price of 150,000 yen (US$2,000), and will eventually be sold internationally as well.
The power pack takes around 6 hours to charge and provides about 300 watt-hours on a full charge, with two power sockets on its front end. Tomihari said the company tried to make it suitable for use in disasters, printing the instructions directly on the device and making it relatively portable, weighing about 26.5 pounds (12 kilograms).
It uses lithium-ion batteries built by Sony that will last over 10 years with daily use, the company said.
