Hi all,

I am seeking some expert to give suggestion on both adaptor.
I have both huawei & samsung adaptor.

Huawei
Input: 100-240V~50/60Hz, 0.5A
Output: 5V ==3A

Samsung (Adaptive Fast Charging)
Input: 100-240V~50/60Hz, 0.5A
Output:
9.0V == 1.67A or
5V == 2A

If I am using huawei adaptor to charge on my Samsung galaxy phone, I guess because of its output, it will spoil my battery?
Please advise.

Most probably your huawei charger will output only 5V 2A to your samsung smartphone. Both huawei and samsung chargers use different fast charging technology. If the charging smartphone does not support the fast charging tech of the charger, then it will output lower power, usually 5V 2A. That's why all companies put advise to use the charger that comes with the smartphone.

Thanks for reply.
I guess I have to stick with samsung charger then...abit worry if I use different charger it might spoil the battery life.
