  1. Hello ,
    I need help. 😉
    Do i need an adapter of some sort to help the powerbank charge my iPhone 8?

    The powerbank seems to be working. The blue pawlights are lit, the flashlight works when plugging it into the bank… but it is not charging my phone.

    Would really appreciate any imput.
    Sincerely, HKRothfuss

    1. Dear Helen Katja Rothfuss,
      the flashlight works when plugging it into the bank means the power output is ok , we suggest change another usb charging cable and make sure the cable & iphone port can be working
