Pointed-tip 18650 batteries and batteries with damaged outer sleeves are NOT compatible and should not be used.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the Normal Version and the Quick Charge (PD) Version?\u003c\/h4\u003e\n\u003cp\u003eA: The Normal Version supports a maximum output of 5V at 2.1A, suitable for standard USB charging. The Quick Charge (PD) version supports multiple output voltages — 5V-3A, 9V-2A, and 12V-1.5A — and automatically negotiates the highest supported voltage with your device for faster charging speeds. If your device does not support 9V or 12V, it will default to the standard 5V output.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Why does the power percentage display seem inaccurate at first?\u003c\/h4\u003e\n\u003cp\u003eA: This is a common characteristic of lithium battery percentage estimation. For the most accurate readings, fully cycle the batteries 2–3 times — meaning discharge to 0% and recharge to 100% each time. After a few cycles, the display will reflect the actual remaining capacity more precisely.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this power bank case come with 18650 batteries included?\u003c\/h4\u003e\n\u003cp\u003eA: No, the 18650 batteries are not included with this case.
