the reason why the computer shutdown with the huawei charger is capacity.
for safety reason , huawei supercharge charger only output 22.5W(5V4.5A/4.5V5A)when the charger communicate with the device in supercharge protocol and both charge and device should be able to accept this capacity which was depends on the status of charger and device (temperture etc.).
when device didn't support supercharge protocol or can't communicate to charger correctly, the charge only output 5V2A in max.
And i want to see with enough power supply and cooling how fast can it be.
