Kindly note: Some customers asked why the mobile phone could not be charged. We have summarized several reasons for your reference:

①The USB charging head is damaged. Maybe you are buying inferior products.

We recommend that you buy products from brands, such as Matein and other brands with USB waterproof backpacks, because the brand has strict inspections on product quality and can get quality assurance, not the data cable and The processing technology of the USB connector is not standard, and there are two situations.

First, the metal contact piece in the data cable or USB interface is relatively thin. As the number of times of use increases, the metal piece is worn out or cannot be contacted and cannot be charged;

Second, the size of the interface is not standardized. If the size is too small, the metal contact piece cannot be contacted and cannot be charged normally.

Therefore, it is recommended to buy a brand backpack and a brand data cable

②The internal constant current charging circuit of the power bank is damaged, which is usually caused by overheating and burning the main charging chip. (Generally, this problem will not occur. You can buy a brand for mobile power to avoid it. Brand mobile power has overcharge, overheat, and overvoltage protection functions)

③The cable between the charging head and the power bank is not connected well, or the cable is broken. (If it's the quality of the mobile phone charging cable or charging cable interface, we recommend you to buy a brand backpack and brand data cable)

Where do I get a power bank from and dose it require a certain spec?

Terry

It would have been nice if you said you need to purchase the power bank separately. That was not at all clear.
