18650 Lithium Battery Charger Module with Type-C Input 5V to 12V DC-DC Step-Up Booster Converter & 3A Fast Charging

Power cuts killing your Wi-Fi or IoT project mid-session? The amiciKart 18650 Lithium Battery Charger Module with Type-C Input is your all-in-one solution — it charges your 18650 cell at 3A fast speed, boosts 5V to a stable 12V output, and automatically switches to battery backup the moment mains power drops.

This compact module packs serious capability into a tiny footprint. The high-efficiency DC-DC step-up booster delivers a rock-solid 12V output at up to 20W peak (15W rated), making it perfectly suited for Wi-Fi routers, Arduino/UNO, Raspberry Pi, IoT sensor nodes, and custom DIY electronics. The USB Type-C input means you can power it from any phone charger, power bank, or 5V adapter you already own — no proprietary connectors, no fuss. The built-in Smart UPS function detects power loss in milliseconds and auto-switches to the 18650 battery, keeping your devices running without a hiccup.

Designed with makers and hobbyists in mind, the low-power circuit lets you remove the indicator LED to save 10mA+, extending battery runtime significantly for always-on builds. Premium-grade components ensure stable, safe performance across robotics, home automation, portable power banks, and backup power systems. Whether you're a weekend tinkerer or a professional prototyper, this module eliminates the need for multiple boards.
