You will need to source 8 flat-top 18650 cells separately. Make sure they do NOT have built-in protection boards or pointed tips, as non-compliant batteries can affect performance and safety.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I charge a device while the power bank is being charged?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! This housing supports simultaneous 5V charging and discharging, so you can top up the battery pack and power a connected device at the same time when operating at 5V.\u003c\/p\u003e\n\u003ch4\u003eQ: What fast charging protocols are supported by the dual Type-C ports?\u003c\/h4\u003e\n\u003cp\u003eA: The dual Type-C ports support a wide range of protocols including PPS, PD3.1, PE1.1, PE2.0, QC3.0, QC2.0, AFC, FCP, and SCP — up to 20W max when using Type-C. For devices without proprietary fast-charging support, PD protocol via the Type-C output offers stable, reliable charging.\u003c\/p\u003e\n\u003ch4\u003eQ: What is low-current mode and when should I use it?\u003c\/h4\u003e\n\u003cp\u003eA: Low-current mode is designed for charging devices that draw very little power, such as wireless earbuds, smartwatches, or small LED lights, which may not trigger standard output thresholds. Activate it with a long press of the button to ensure these smaller devices charge without the output shutting off.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
