Advanced Charging Process: </strong>The micro/type-c usb mobile power bank features a sophisticated charging process with three stages: trickle mode, constant current mode, and constant voltage mode. When the battery voltage is below 3V, it charges in trickle mode at 300mA. Once the voltage exceeds 3V, it switches to constant current mode, charging at full speed with a power output of up to 21W. Finally, it enters constant voltage mode as it approaches the target voltage (e.g., 4.2V), gradually reducing the current until the charging is complete.<br /> <strong>2. Comprehensive Protection Mechanisms: </strong>The 18650 charging module includes multiple protection features such as input overvoltage protection, output overcurrent/short circuit protection, overcharge overvoltage protection, and temperature protection. These safeguards ensure safe and reliable charging in various conditions.<br /> <strong>3. Wide Range of Fast Charging Protocols:</strong> The quick charging mobile power module supports a variety of fast charging protocols including PPS, PD3.0, PD2.0, QC4+, QC4, QC3.0, QC2.0, AFC, FCP, SCP, PE2.0, PE1.1, SFCP, and VOOC. This compatibility ensures your devices charge quickly and efficiently, regardless of the protocol they require.<br /> <strong>4. Versatile Input Fast Charging Support:</strong> The mobile power bank circuit board supports input fast charging protocols such as PD3.0, PD2.0, AFC, FCP, SCP, and PE1.1. This feature allows for rapid recharging of the power bank itself, minimizing downtime and keeping your devices powered up.<br /> <strong>5. High Efficiency and Compatibility:</strong> The fast charging mobile power module offers switch charging with a current up to 5A and an efficiency of up to 95%. It supports various battery types including 4.2V, 4.35V, 4.4V, and 4.5V, and adheres to JEITA standards with temperature <span>ring</span>control to ensure optimal performance and safety.<br /> <br /><br/><br/><span><strong>Specification:</strong></span><br /> <span>Origin: Mainland China</span><br /> <span>Type: Module</span><br /> <span>Condition: New</span><br /> <span>Hign-concerned Chemical: None</span><br /> Input voltage: 4.5-13.5V<br /> Battery voltage: 2.8-4.5V<br /> Operating temperature: -20~+60℃<br /> 1.

It doesn't need to be too thick, but it shouldn't be too thin. Too thin will cause safety hazards. (Because the current on the battery side is very large)<br /> 2.The motherboard has its own protection chip, and the battery does not need to be equipped with a protection board. If there is one, please remove the protection board and connect the motherboard directly to the battery. (Because the built-in one generally cannot pass large current, it will be protected when the output power is large)<br /> 3. Friends who use alligator clips to test the motherboard, please do not charge your mobile phone, don't ask why, anyway, you can't use it this way. If you need to charge your mobile phone, you must weld it well.<br /> 4.The battery uses 4.2V 18650/polymer/ternary lithium battery, a large single piece is enough, and multiple 18650s can be connected in parallel. Lithium iron batteries, disposable dry batteries, nickel-hydrogen batteries, lead-acid batteries, nickel-cadmium batteries, etc. cannot be used. Batteries cannot be connected in series. The first time you power on, the battery display may be inaccurate. Please discharge the battery first and then fully charge it. When all four lights are on for the first time, you can continue to charge for more than 5 hours. The battery will not be damaged, so there is no need to worry.<br /> 5.Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!<br /> 6.Please allow 1-2cm measuring deviation due to manual measurement. </p> <br />&nbsp;<br /> </div> <br /> <div> <br /> </div> <div style="padding:15px;border:1px solid #AEAEAE;"> 1 X&nbsp;Micro/Type-C USB Mobile Power Bank&nbsp;<br /> </div> <br /> <div style="text-align:center;"> <div> </div> <div> <br /> </div> </div> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> </td> </tr> </tbody> </table></div></div>
