How can I see the power bank's battery percentage with a software?

To see a power bank's battery percentage using software, you typically need a power bank that includes Bluetooth connectivity or is compatible with a mobile app. Download the manufacturer's app or a compatible third-party app on your smartphone, then connect the power bank via Bluetooth. Once connected, the app should display the battery percentage along with other useful information. If your power bank lacks this feature, using a smart power bank with built-in display indicators may be necessary.
