This powerbank has 10000mAh capacity. It has two output ports and a micro usb input charging port. I liked the powerbank personally as it has inbuilt type-B and type-C charging cable.
Initially the powerbank was very efficient and the phone would charge very quickly. After 2-3 months of regular usage (not heavy usage) the type-B cable stopped working. I used only the type-B cable. I didn’’’’t bother much and started using external charging cable.
After 5-6 months even if i used the external charging port the phone would not charge faster.
And recently when i had been charging the phone from the powerbank i noticed that the plastic outer casing was coming off also the powerbank was very hot. The charging cable’’’’s connector was also hot.
Recently I’’’’ve noticed that the capacity of the powerbank had reduced a lot. At first it could charge a 4000mAh phone 100% twice without any problem. Now I’’’’m not able to charge even 80% once.
I recommend that you don’’’’t buy this powerbank.
