are you sure with only charging with powerbank will fry your phone motherboard? how about normal ac charger?
there is a built in circuit to limit the current on phone motherboard. i had tried using 5V 3A charger to change my phone. when i measure, it only accept the current upto 1.1-1.2A and not 3A.
there are also built in circuit for powerbank itself, that's why it will have 2 output : 1A and 2.1A.
the rating is showing the max current that it allow, not must be exactly 1A.
so far i tried my times for overnight charging no problem on my phone. i like the feature that it will auto cut off when my phone is fully charged.
There is no problem with normal AC charger. So I can use any type of power bank irrespective of the higher output rating of the mA compare to the smartphone input charging capacity.
Maybe I have a faulty Yoobao powerbank? How do I test using multimeter?
I do not dare to use another phone to charge again after it fried both my Samsung Galaxy Note and Nokia Lumia 900, fortunately both of them still under warranty. After charging both my phone went dead. Cannot on it back using what ever method.
So how do we test the power bank device that it is working properly?
How do we determine if the device has auto cut off when the batter charging is fully completed?
