Anker product question

Greetings folks,

At the risk of sounding a complete idiot, I don’t know much about Volts, Amp and Hz values so I wondered if there is anyone on here that does.

I recently purchased a W-King D10 portable power speaker, but the product does not come with a charger, it has to be purchased separately.

The product requires a 5V 2A power adapter.

I recently purchased an Anker Powerport+1 with Quick Charge 3.0 charger, but it has multiple values written on the side, which are:

3.6-6.5V 3.0A 10.8W-19.5W / 6.5V-9.0V 2.0A 13.0W-18.0W / 9.0V-12.0V 1.5A 13.5W-18.0W

Does this mean this product adjusts its power compared to what it is connected too and will work on devices who’s power requirements range between 3.6V to 12.0V?

I’ve heard wrong V and A values can destroy a device so I want to be careful.

In short, will this adapt to a 5V 2A device?

Thank you kindly.
