Hi Sabit_Darski666,
Thank you for using the Apple Support Communities! The guidance for the article below can help:
How to use your MagSafe Battery Pack
Charge your MagSafe Battery Pack and your iPhone
If both your iPhone and MagSafe Battery Pack need to be charged, you can charge them at the same time. Plug the MagSafe Battery Pack into a power adapter and then attach your MagSafe Battery Pack to your iPhone. Using a 20W or higher power adapter, the MagSafe Battery Pack can charge your iPhone with up to 15W of charging power.
You can also charge both if you attach your MagSafe Battery Pack to your iPhone, then plug your iPhone into a power source. You might want to charge this way if you need to connect your iPhone to another device while charging, like if you're using wired CarPlay or transferring photos to a Mac.
If you charge your iPhone and MagSafe Battery Pack at the same time, your iPhone might charge to 80% or higher before your MagSafe Battery Pack begins charging.
Hope this helps!
Have a great day.
