A Power Bank's Mah Rating and What It Means in Real Charges
A power bank’s labeled mAh rating never matches its real charging output. Inside the device, voltage conversion and natural heat generation inevitably reduce the usable energy. For instance, a standard 10,000 mAh unit from brands like Anker or Xiaomi usually delivers only about 6,000 to 7,000 mAh to your phone. Understanding this efficiency gap is crucial, as it determines whether you get a full backup charge or find yourself stranded with a dead battery.
