Laptop Charger Options

I have a Lenovo Yoga 900 that I have lost the power charger to. Still have the cable but it doesn't work on other usb wall adapters. Have looked for replacements at MemEx, bestbuy, staples and a couple other computer shops in town with no luck. Even thought about buying a second yoga to get one but can't find one in stock anywhere.

Any suggestions on where I can get a charger quickly or substitute something to get this computer running?
