Product overview A 13.8V power converter rated 10A and 140W designed for reliable lowvoltage power delivery with builtin safety protections. Suitable for use with vehicle and other 13.8V power systems when powering or charging electronic devices. Key benefits Protects connected equipment: builtin overload protection, short circuit protection, and overheating protection reduce the risk of damage if too many devices are connected or abnormal conditions occur. Clear compatibility and capacity: 13.8V input with a 10A current rating and 140W maximum output makes it suitable for many common portable electronics when matched to their power needs. Practical and safe operation: guidance and protections help avoid electrical sparks and unsafe conditions during plugging and unplugging and in regular use. Main specifications Input voltage: 13.8V Rated current: 10A Rated power: 140W Safety features: overload protection, shortcircuit protection, overheating protection Usage guidance and safety Environment: use only in a dry, well ventilated area. Do not use in damp, temperature, or flammable and explosive environments. Plugging and unplugging: always turn off the electrical equipment before connecting or disconnecting to avoid sparking. Power selection: calculate the total power of all devices to be connected and choose a converter that can handle the combined load with margin to improve conversion stability and avoid overload. Voltage compatibility: if an electronic device supports a wide input voltage range of 100V to 240V, normally only a simple plug adapter is required to change socket shape. If the device does not support the local voltage, select a voltage converter with a transformer function. Compatibility and performance notes suited for use with devices that can be powered from a 13.8V source or via appropriate conversion to required voltages. Rated 10A and 140W means continuous loads should remain within these limits to ensure proper protection and performance. For multiple devices, add individual device wattages and ensure the sum does not exceed the 140W rating. Practical use scenarios Invehicle charging and powering: run or charge laptops, cameras, and mobile devices from a vehicle 13.8V power system while using the converter and following power capacity guidelines. Field photography or location work: power camera chargers, battery packs, and small accessories when mains power is not available, provided total load stays under 140W. Boat or recreational vehicle use: provide stable power for electronic devices on vessels or RVs equipped with 13.8V systems, observing dry and ventilated conditions. Quick checklist before use Verify device input requirements and whether a simple plug adapter or a transformertype voltage converter is needed. Add up device wattage and confirm total is below 140W with a safe margin. Ensure installation location is dry and ventilated and clear of flammable materials. Turn off devices before connecting or disconnecting. This product provides straightforward power delivery from a 13.8V source with essential protection features and clear usage guidance to help safeguard equipment and maintain reliable performance.
