Are you really serious about this???
QuoteThe 20000 mAh capacity is also quite spacious and enough to fully recharge most laptops multiple times. Even the gaming-level MSI GS77, for example, integrates a battery capacity of "only" 6250 mAh.
There are few power banks that could actually charge notebooks "multiple times" but defintiely not this one. I used to love notebookcheck.net because authors actually used to have also a technical knowledge about what they write and not just copying information...
The key fact is that while this powerbank has 20000mAh (20Ah) but it says nothing without rated voltage of the cells (or Wh). You cant compare Ah vs Ah if the voltage is not the same!!! And in powerbanks its common practice to use the Ah related with single cell configuration (4,2V), while the mentioned laptop has 4 cells in series to make it 16,8V. So its comparing about 84Wh Baseus power bank vs. 105Wh MSI battery. And no, you cant charge 104Wh batterry from 84Wh power bank, not even once. It might be a good power bank, but prease correct this nonsense...
