300W Car Power Inverter - 12V to 110V AC Converter with 2 AC Outlets & 4 USB Ports (2 PD 36W + 2 QC3.0 30W), Voltage Display, Cooling Fan for Laptop/CPAP/Travel

Regarding the automotive power inverter, the following aspects need to be noted:

Efficient and stable output design

This product follows industry standards and can stably output a rated power of 300W (continuous load). To ensure that the 300W rated power output performance meets the standard. Since some vehicle models may have circuit differences and different fuse loads, it is recommended that users confirm the compatibility of the vehicle cigarette lighter interface before use, and confirm that the fuse load can support the stable operation of the inverter at 300W. The output voltages of the USB-A and USB-C ports of the product are shared. All data can be found in the product manual.

Product Operating Environment and Test Instructions (Technical Suggestions):

This automotive inverter is specifically designed for the vehicle environment and is compatible with the vehicle's power system. Its performance parameters are (300W rated power / 12V DC input). When the vehicle battery capacity is sufficient, it usually can meet the power supply requirements, allowing the 300W power of the automotive inverter to work normally (it is recommended to use or test after starting the engine). It is not allowed to directly connect to the household power supply or other non-vehicle equipment for testing. Testing in non-vehicle environments may result in inaccurate test results and data.

Protection mechanism: If the power input does not meet the standards, it may result in insufficient power output or trigger an automatic protection mechanism (such as under-voltage shutdown), which is a normal circuit protection function. The product is equipped with multiple protection mechanisms including under-voltage, overload, short circuit, and overheating.
