In general, you should not use Samsung DeX with a battery pack. However, DeX may work with some battery packs. Using a genuine Samsung power supply is recommended.

You can charge your device if it is connected to your PC with a cable. However, your device’s battery charging performance may vary, depending on how you’re using Samsung DeX. In general, a PC’s USB port supplies less power than a regular charger.

In this case, the battery level may still drop gradually even if you are charging the device.
