Connect laptop charging cable to JBL Xtreme 2?

I wanted to ask if it is possible to use my JBL Extreme 2 with a Panasonic charging cable with an output of 16V u. 2.5A to load. I don't have the original charging cable with me and the battery is as good as empty. So it would not be a permanent solution but only once.

The tension has to be right. Electricity can be neglected.
