We would recommend you purchase a new power cable from Taobao.
However, users outside of Mainland China, regarding the shipping cost, had better get one locally. There is a nominal voltage and current on the plug (or in the product page), indicating the maximum voltage and current. You can choose the same type and parameter of power cord.
For example, you should choose power cable of 250V/10A/25A for the Sqair.
