Can powerbanks automatically change output voltage and amperage ?

Some powerbanks can provide a multiple levels of voltage and amperage. I can t see any button that can be used to switch between output volts and amperes.

Can these powerbanks automatically adjust output voltage and amperage according to a connected device ?

Yes, some powerbanks can automatically switch between available voltage and amperage output levels.

After you connect a device to this type of powerbank, it automatically recognizes what output level should be used.

For example, new Baseus powerbanks have the BPS2.0 intelligent power distribution technology. It is a proprietary charging technology, that automatically adjusts the voltage and amperage output levels.
