Full Product Description

Built-in 5V Output via Type-C Cable

This specialized 18650 battery eliminates the need for external boost converters by outputting a stable 5V directly through its integrated 10cm Type-C male cable. While standard 18650 cells only provide a raw 3.7V output, the SAVANGER V4.2 features internal circuitry that steps the voltage up to 5V. This plug-and-play design allows you to directly power modern Type-C development boards, sensors, and custom LED lighting rigs instantly, drastically reducing the wiring complexity of your compact DIY projects.

Convenient Type-C Recharging

You can recharge this battery directly using a standard smartphone cable via the female Type-C port located on the top cap. This completely removes the need to purchase or carry a bulky, dedicated 18650 cylindrical battery charger. Whether you are at your workbench or in the field, you can easily top up the 2000mAh capacity using a standard USB port or portable power bank, ensuring your custom electronics are always ready to deploy.

Pro Tip from Our Technicians

You must strictly use a standard 5V USB power adapter to recharge this battery and absolutely avoid using PD (Power Delivery) or QC (Quick Charge) fast chargers. Our Sham Shui Po DIY electronics specialists warn that plugging this battery into a fast charger that exceeds the strict 5.5V charging limit will instantly destroy the internal Battery Management System (BMS) and pose a severe fire hazard.
