No, the power bank 22.5w fast charging mode supports fast charging mobile phones. Most of the charging banks on the market now have fast charging mode, and most of these fast charging mode mobile phones are supported, for 22.5w fast charging bank, it belongs to the ordinary mode for some 55w and 65w charging mobile phones, of course, it can be charged, but it is slower than its own charging speed. For the 20w mobile phone, it does belong to the fast charge mode. The 22.5-watt charging treasure can fully support the charging mode of fast charging mobile phones. You just need to plug it into the second port, which is the high current port shown above.
This is OK, can be the reason is: mobile phone charging can withstand up to 30w electrical power, now the fast charging head, its maximum output is only 22.5w, does not exceed the maximum carrying capacity of the mobile phone, so this configuration is OK.
