Key benefits One compact adapter kit that converts power between a wide range of devices, reducing the need to carry multiple chargers and cables. Supports charging function so you can power or recharge batteries and devices directly through the adapter. Broad compatibility with common barrel and plug types, letting you connect drones, laptops, tools, energy storage systems, solar panels and more without custom wiring. Female-series adapters provide a safe, standardized interface for power conversion and easy plug-and-play use. What it does Converts and adapts power connections between different device plug types while preserving charging capability. Acts as a female-series intermediary for safe, reliable power transfer and makes adapters interchangeable across equipment. Compatibility and connector sizes Includes the following connector types: USB‑C, 5.5 × 2.1 mm, 5.5 × 2.5 mm, 7.4 × 0.6 mm, EC5, and 7.9 × 0.9 mm. Designed for wide compatibility with: drones, laptops, electric vehicles (e.g., e-bikes and scooters), power tools, energy storage devices, solar panels, and small appliances. Important attributes Function: Power conversion and charging support for a variety of devices. Form factor: Compact, easy to carry and swap between devices in the field or at home. Performance: Maintains reliable electrical contact to support charging and power delivery for compatible equipment. Build: Robust construction suitable for repeated connection and disconnection in everyday use. How it solves common problems Eliminates the need to carry multiple proprietary plugs or search for rare connectors when traveling or working off-grid. Simplifies connecting solar output or power-bank sources to device-specific inputs by using the correct adapter tip. Makes it easy to adapt legacy equipment to modern chargers or to repurpose a single power source across several devices. Typical use scenarios 1) Field drone operations: Use a power bank with USB‑C output and the matching barrel adapter to recharge drone batteries on-site without carrying the original charger. 2) Solar charging setup: Connect a portable solar panel to an energy storage device using the appropriate female-series adapter to enable direct charging during daylight hours. 3) Workshop or travel: Swap adapter tips to power small tools, laptops or vehicle accessories from a single power supply when standard plugs don’t match. What’s included A set of female-series adapter connectors covering USB‑C, 5.5 × 2.1 mm, 5.5 × 2.5 mm, 7.4 × 0.6 mm, EC5, and 7.9 × 0.9 mm for broad compatibility and flexible power conversion. Notes on safe use Ensure voltage and current compatibility between source and target devices before connecting. Use the correct connector size for the device input to avoid loose contacts or damage.
