      Hi GuccGG,
      Sorry the battery life and charging speed didn’t meet your expectations. Actual usable capacity can vary depending on the phone model, and larger‑battery phones may drain a power bank faster than expected. If the unit seems unusually slow or the capacity feels lower than it should be, our support team can help check or replace it:
