Huawei Mate30 supports 40W wired super fast charge and 27W wireless Super fast charge. Huawei mate30 can use 100w fast charge, but it will automatically be reduced to 40w charging maximum charging protocol for compatibility, so the use of 100w charger is equivalent to 40w charging, it can be used normally.

Can not use a 100w charger for a long time to charge, otherwise the battery life will be.
