Each module handles the full charge cycle — constant current bulk charge followed by constant voltage top-off — and cuts off automatically when the cell is full. The 5-pack gives you enough modules for multiple projects or replacements.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5 modules included\u003c\/strong\u003e — five identical charging modules for multiple projects or spares\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple USB input options\u003c\/strong\u003e — available in Type-C, Micro USB, and Mini USB variants; check variant for input connector type\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCC\/CV charge profile\u003c\/strong\u003e — constant current \/ constant voltage charging profile correct for Li-ion and LiFePO4 cells\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic cutoff\u003c\/strong\u003e — stops charging automatically when the cell reaches full voltage; prevents overcharging\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED charge indicator\u003c\/strong\u003e — red LED during charging; blue or green LED when charging is complete\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact PCB form factor\u003c\/strong\u003e — small board size for easy integration into DIY enclosures and projects\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOvercharge protection\u003c\/strong\u003e — built-in protection circuit prevents cell damage from overcharging\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide compatibility\u003c\/strong\u003e — compatible with 18650, 18500, 14500, and other standard Li-ion cell sizes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWho It’s For\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDIY electronics builders who need a simple, reliable charging solution for Li-ion cell projects\u003c\/li\u003e\n\u003cli\u003eMakers and hobbyists building custom power banks, flashlights, or battery-powered devices\u003c\/li\u003e\n\u003cli\u003eEngineers prototyping battery-powered products who need a quick charging solution\u003c\/li\u003e\n\u003cli\u003eAnyone who needs to charge 18650 cells from a USB source without a dedicated charger\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eSolder the module’s B+ and B− pads to the positive and negative terminals of your Li-ion cell.\u003c\/li\u003e\n\u003cli\u003eConnect a USB cable to the module’s input port.\u003c\/li\u003e\n\u003cli\u003eThe red LED will illuminate to indicate charging is in progress.\u003c\/li\u003e\n\u003cli\u003eWhen charging is complete, the LED will change to blue or green and current will stop automatically.\u003c\/li\u003e\n\u003cli\u003eDisconnect the USB cable after charging is complete.\u003c\/li\u003e\n\u003c\/ol\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat charge current does it deliver?\u003c\/strong\u003e\u003cbr\u003eMost standard modules deliver 1A charge current. Check the variant specifications for the exact charge current — higher current modules charge faster but generate more heat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use it with LiFePO4 cells?\u003c\/strong\u003e\u003cbr\u003eStandard Li-ion modules charge to 4.2V, which is too high for LiFePO4 cells (which charge to 3.65V). Use a module specifically designed for LiFePO4 chemistry if charging LiFePO4 cells.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs it safe to leave charging unattended?\u003c\/strong\u003e\u003cbr\u003eThe automatic cutoff and overcharge protection make these modules safe for unattended charging under normal conditions. However, always charge Li-ion cells on a non-flammable surface and avoid leaving them charging overnight as a general safety practice.\u003c\/p\u003e","brand":"Authority Asset Brand","offers":[{"title":"Mini with protect \/ 5PCS","offer_id":48361212412148,"sku":"14:193#Mini with protect;822:200052431#5PCS","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Micro USB no protect \/ 5PCS","offer_id":48361212444916,"sku":"14:350850#Micro USB no protect;822:200052431#5PCS","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Micro with protect \/ 5PCS","offer_id":48361212477684,"sku":"14:173#Micro with protect;822:200052431#5PCS","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Type-C no protect \/ 5PCS","offer_id":48361212510452,"sku":"14:1254#Type-C no protect;822:200052431#5PCS","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Type-C with protect \/ 5PCS","offer_id":48361212543220,"sku":"14:771#Type-C with protect;822:200052431#5PCS","price":16.99,"currency_code":"USD","in_stock":true},{"title":"Mini USB no protect \/ 5PCS","offer_id":48361212575988,"sku":"14:365458#Mini USB no protect;822:200052431#5PCS","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0823\/0564\/6836\/files\/Hb679ac810af24ec3bd86012436cc94bf0.webp?v=1780173876","url":"https:\/\/authorityassetbrand.com\/products\/5-pcs-type-c-micro-mini-usb-5v-1a-18650-tp4056-lithium-battery-charger-module-charging-board-with-protection-dual-1a-li-ion","provider":"Authority Asset Brand","version":"1.0","type":"link"}
