Uninterruptible power supply functionality: provides continuous power to attached devices while simultaneously charging the internal lithium battery, so devices stay online during short outages or when mains power is interrupted. Clear power ratings and compatibility: rated for 15W continuous output with a 20W boost capability. Ideal for lowpower electronics such as smartphones, tablets, Wi‑Fi routers, IP cameras, small IoT devices, and LED lighting within that power range. efficiency boost technology: uses a performance MOSFET design to deliver up to 96% conversion efficiency, reducing energy loss and heat generation for better performance and longer component life. Comprehensive battery protection: integrated safeguards against overcharge, overdischarge, overheating, and excessive current to preserve battery health and reduce risk during normal use. Reliable performance in tight spaces: combines UPS behavior and battery charging in one unit for straightforward integration into home or office setups without adding extra components. Simple integration and use: designed to maintain device function automatically when mains power drops and to resume normal charging and operation when power returns. Typical applications Home network backup: keep your modem or Wi‑Fi router online during brief power interruptions so remote work, streaming, and smarthome devices remain connected. Mobile device charging during outages: ensure phones and tablets continue charging and operating when grid power is unstable, with battery protections minimizing wear. Lowpower security and IoT systems: maintain continuous operation of IP cameras, sensors, and controllers that require a stable 15Wclass power source with occasional 20W peaks. What sets this product apart Simultaneous UPS and batterycharge functionality prevents interruptions without requiring a separate charger and backup unit. performance MOSFET design achieves up to 96% efficiency for reduced losses and cooler operation. Builtin multilevel battery protection reduces maintenance and extends usable battery life.
