How to charge power bank by MacBook Pro M1

Hi there PavelBar,

Thank you for using the Apple Support Communities! It sounds like you're asking about fast charging your MacBook Pro. We're happy to help.

Check out: Fast charge your 14-inch or 16-inch MacBook Pro. "The 14-inch MacBook Pro and 16-inch MacBook Pro with Apple silicon support fast charge. When you connect the appropriate power source and cable, you can quickly charge your battery up to 50 percent in 30 minutes." This article lists which power source and cable is needed to fast charge, based on your specific model MacBook Pro. Please review it and let us know if you have any other questions on this topic.

Best regards.

Your MacBook Pro uses smart charging to charge in the optimum way, and only when necessary. An external power source must use USB Power Delivery Protocol, or NOTHING will happen.

An external power supply that provides "USB Power Delivery" (like certain displays) must negotiate over the USB cable using USB Power Delivery Protocol, can not 'force itself' on your Mac. The Voltage and Current are delivered only after your Mac requests and the charger agrees to supply power under certain controlled conditions. The computer is in control of the entire process.
