OUT+\/OUT− are the protected output after the DW01A\/FS8205A protection circuit. Always connect your load to OUT+\/OUT− to benefit from overdischarge and short-circuit protection. Connect the battery to B+\/B− only.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can I charge and use the load simultaneously (pass-through charging)?\u003c\/strong\u003e\u003cbr\u003eA: Yes, but with limitations. The TP4056 charges at 1A maximum. If the load draws more than the charging current, the battery will discharge even while connected to USB. For stable pass-through, ensure the load current is less than the charge current (1A). For higher load currents, use a dedicated power path management IC (BQ24074, MCP73871).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: How long does it take to charge an 18650 cell (2000mAh) with this module?\u003c\/strong\u003e\u003cbr\u003eA: At 1A charge current: approximately 2–2.5 hours for a fully depleted 2000mAh cell (accounting for CC→CV transition and termination). The red LED turns off and blue\/green LED lights when charging is complete (current drops to ~100mA termination threshold).\u003c\/p\u003e\u003ch3\u003ePackage Contents\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1× TP4056 Li-ion Charger Module (Type-C \/ Micro USB, with DW01A protection)\u003c\/li\u003e\u003c\/ul\u003e","brand":"Keszoox","offers":[{"title":"18650 Mini","offer_id":46991465480427,"sku":"14:351074#18650 Mini","price":4.48,"currency_code":"USD","in_stock":true},{"title":"TP4056 MICRO","offer_id":46991465513195,"sku":"14:350852#TP4056 MICRO","price":4.12,"currency_code":"USD","in_stock":true},{"title":"TP4056 Type-C","offer_id":46991465545963,"sku":"14:4044226#TP4056 Type-C","price":4.32,"currency_code":"USD","in_stock":true},{"title":"TP4056 Mini","offer_id":46991465578731,"sku":"14:10#TP4056 Mini","price":4.12,"currency_code":"USD","in_stock":true},{"title":"18650 Type-C","offer_id":46991465611499,"sku":"14:29#18650 Type-C","price":4.32,"currency_code":"USD","in_stock":true},{"title":"18650 MICRO","offer_id":46991465644267,"sku":"14:173#18650 MICRO","price":4.12,"currency_code":"USD","in_stock":true},{"title":"TP4056 MICRO black","offer_id":46991465677035,"sku":"14:175#TP4056 MICRO black","price":4.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1005\/8731\/files\/tp4056-lithium-battery-charger-module-5v-1a-typec-micro-usb.webp?v=1761719738","url":"https:\/\/keszoox.com\/products\/tp4056-li-ion-charger-module-type-c-micro-usb-5v-1a-18650-dw01a-protection","provider":"Keszoox","version":"1.0","type":"link"}
