It can be filled,
However, it can only charge 5V2A, because Huawei's original 22.5W charging head only supports 5V4.5A\/4.5V5A, 5V2A output, and does not support 9V2A output
In fact, Huawei's charging head cannot be compatible with all other charging power of its own,
18W is FCP fast charge and 22.5W is SCP fast charge. It's not easy to change unless you change the PCB.
It needs to go through the dc2dc in the phone, and 22.5w is a pass-through, and the functional realization is still short of at least 2 mos to achieve path switching.
If the phone has a 22.5w fast charge agreement, it is OK, but do not use 22.5w charge, easy to damage the battery, this depends on the situation.
