Thank you and appreciate your response. Yes, you are right I can charge using AC output, but just wondering if there is a USB c only solution.
Rather than getting into technical specification, can someone (or Philips) point to a specific product (link on amazon will do) which has been tested and worked fine? (Like a link to amazon showing so and so power bank should be able to charge your PPM while you are watching something on it)
For example: Philips listed a bunch of BT speaker which they tested
Do they have similar list of powerbanks which they tested and can share?
