Lithium iron phosphate (LiFePO₄) batteries are not compatible and must not be used, as the charge\/discharge voltage ranges differ significantly.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the PD 100W module support fast charging for all smartphones?\u003c\/h4\u003e\n\u003cp\u003eA: The module supports mainstream public fast-charging protocols including PD, QC, FCP, and SCP. Most modern Android and iOS smartphones that support any of these protocols will benefit from fast charging. Proprietary or manufacturer-specific protocols that do not have public standard support may charge at standard speeds only — always verify your device's supported protocols.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Why does the battery level display seem inaccurate when I first connect the battery?\u003c\/h4\u003e\n\u003cp\u003eA: This is completely normal. The battery meter uses a \u003cstrong\u003eself-learning calibration system\u003c\/strong\u003e that refines its capacity estimation over several full charge and discharge cycles. After 3–5 cycles, the display will accurately reflect your battery's true charge level.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use the Type-C port for both charging the power bank and charging my devices?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — the Type-C port supports \u003cstrong\u003ebidirectional operation\u003c\/strong\u003e. It can accept input (to charge the power bank batteries) and deliver output (to charge connected devices). The USB-A port is output-only.
