The YX850 handles automatic switching, and the TP4056 handles safe charging. No need to research compatibility.\u003cbr\u003e\u003cbr\u003eFully Automatic Protection: When main power is on, the YX850 charges the battery via the TP4056. During a power outage, it switches automatically within milliseconds to 18650 battery power, keeping your router, CCTV camera, or IoT device online without data loss.\u003cbr\u003e\u003cbr\u003eType-C Fast Charging \u0026amp; Protection 2-in-1: The TP4056 module supports Type-C \u0026amp; Micro USB input with up to 1A charging current. It integrates charging and full protection (over-charge, over-discharge, over-current, short-circuit) for safe 18650 battery management.\u003cbr\u003e\u003cbr\u003eWide Voltage Compatibility: The YX850 works with 5V-48V devices, compatible with everything from 5V MCUs to 12V routers and 24V CCTV systems. One kit, multiple applications.\u003cbr\u003e\u003cbr\u003eDIY Friendly, Plug \u0026amp; Play: Modules have clear labels. Simply connect power, battery, and load.

Building a professional Uninterruptible Power Supply (UPS) is easier than you think! This kit combines two of the most reliable modules on the market. The YX850 acts as the \"smart brain,\" monitoring power and switching seamlessly during a cut. The TP4056 acts as the \"energy heart,\" safely and quickly replenishing your backup battery. Together, they form a complete solution for continuous power backup of your critical devices.\u003c\/p\u003e\n\u003cp style=\"font-size:24px;font-weight:bold;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003e🚨 Critical Setup Guide \u0026amp; Warnings\u003c\/p\u003e\n\u003cp style=\"font-size:16px;font-weight:bold;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003e⚠️ 【Voltage Matching is THE Rule】\u003c\/p\u003e\n\u003cp style=\"font-size:13px;font-weight:normal;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003eYour main power adapter voltage, backup battery voltage (e.g., 18650 pack), and load device voltage (e.g., router) MUST BE IDENTICAL!

Charger Connection: Connect the TP4056's B+\/B- to your 18650 battery pack.\u003cbr\u003e2. System Integration: Connect your main power adapter to YX850's VIN. Connect the TP4056's OUT+\/OUT- (battery output) to YX850's BAT. Connect your load device (router) to YX850's VOUT.\u003cbr\u003e3. Power Test: With main power on, the TP4056 red LED should indicate charging. Unplug the main power—the YX850 should instantly switch to battery, and your device stays on.\u003c\/p\u003e\n\u003cp style=\"font-size:16px;font-weight:bold;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003e❌ 【Important Notes】\u003c\/p\u003e\n\u003cp style=\"font-size:13px;font-weight:normal;text-align:left;color:rgb(67, 70, 73)\" class=\"word-break white-space mt-10\" align=\"left\"\u003e* Switching Moment: The YX850 has a \u0026lt;1s brief power interruption during switching.
