상품 특징

• 【Seamless Switching Function】Our UPS battery boost charging module features an uninterruptible power supply (UPS) function. When the external power supply is interrupted, it automatically switches to battery power without delay. When power is restored, it automatically resumes external power supply and charges the battery, ensuring continuous operation of devices such as routers and cameras, and preventing network interruptions caused by power outages
• 【Performance Enhancement】Our booster converter module has a rated power of 15W and a peak power of 20W; it uses a BOOST voltage-boosting circuit, achieving a maximum conversion efficiency of 96%; it supports adjustable output voltages of 5V/9V/12V; the Type-C interface supports a maximum current of 5A; it can charge 18650 lithium batteries and 3.7V lithium batteries; it is equipped with a dual-color LED indicator to display the charging status
• 【Safety Protection】Our charging power supply module provides overcharge, over-discharge, over-temperature, and overcurrent protection; automatically enters protection mode in case of a short circuit; can be reactivated via 5V charging after fault resolution; prevents damage to the module and connected devices; ensures safe use during charging and power supply processes
• 【Versatility】Our lithium battery charger module features two 18650 battery slots; compatible with Micro USB and DC 5V input interfaces; suitable for routers, cameras, development boards, and other low-power DC devices; supports connecting multiple batteries in parallel to increase capacity; easy to install and operate, no complex setup required
• 【Durable Design】Our UPS battery boost charging module features an internal 12A high-current MOSFET for stable performance; static power consumption is only 25mA; power consumption can be further reduced by removing the output indicator light; operates normally under high-power conditions with proper cooling; provides a long service life for everyday use
