Can I use a 5v to 12v boost usb cable with the Liitokala Lii-500?

I was wondering if I could safely use one of these to charge with the Liitokala Lii-500 since the included power adapter is too bulky. The answer might probably be no but just wanted to get your opinion.

I don't see a Current or power rating....
For this cable to work you need the power supply and cable to support the required input power of the liitokala

Yeah most cables I found are stingy with the technical specs. Thanks for the insight.
