No. Huawei p30pro will not break with 66w charger. Because the charging power supported by this phone itself is relatively high, it can be charged normally. More than that, the double-string cell needs a 2:1 chip for voltage reduction when discharging, and its own conversion efficiency will lead to a waste of 3% to 4% of power.
The single-cell charging system can avoid the above problems, but it faces great challenges to increase the charging power to more than 100W.
The 66w charger is only able to charge electronic products with a maximum charging speed of 66w, and the p30Pro is up to 40w, so it will not charge the phone
