It is normal for the Mi Fast Charger with GaN Tech too hot during use.
Compared with other chargers, the heat will be more obvious, but Xiaomi chargers are all in line with national standards.
Tip:
Mi Fast Charger with GaN Tech will generate more heat than normal chargers, and there is no need to apply for the after-sales service when encountering heat problems, unless the heat causes the shell to melt.
