Ymup [JP], a Shizuoka-based company with a bad homepage, has developed a backpack with an integrated oxygen generator powered by batteries. The portable device comes with a remote controller and is - according to Japanese newspapers - a world first.

Users can use the backpack if they need oxygen while mountain trekking or hiking, for example. The oxygen with 30% concentration can be inhaled through a nozzle. The company claims the battery lasts for about 2 hours.

Ymup plans to sell their backpacks (1.3kg, 20l volume) in 3 different versions starting July 31st. Prices will range between $880 and $1,150.
