Preface
The car inverter can invert the 12V DC power of the car battery into AC power output, and when the early notebook did not support USB-C charging, many consumers would use the car inverter to connect the laptop power supply to charge the laptop, which is also the main use case of the car inverter.
The charging head network dismantled four on-board inverters, among which the two well-known brands represented by Baseus and Greenlink recently launched on-board inverters have stronger performance, which is enough to meet the power needs of car refrigerators, drones, laptops, etc.
Baseus inverter has a maximum output power of 500W, supports 150W output power when using a car cigarette lighter, and can provide 500W output power when directly connected to a battery. Greenlink's supports 150W output power. Both inverters are equipped with a fast charging interface, which can be used as an inverter and can also be used as a car charger to quickly charge mobile phones. The following brings a dismantling summary of two different brands of on-board inverters, let's take a look at the internal solutions and materials.
Baseus倍思
Baseus 500W super silicon inverter
Baseus this super silicon vehicle inverter supports 500W output power, the matching DC input line has the function of automatic power selection, the output power is 150W when connected to the cigarette lighter, which can meet the use of laptops and mobile phones, and can be connected to electric kettles, rice cookers, Xiaoice boxes and other electrical appliances when using battery clamps to connect batteries. The inverter is a pure sine wave output with good compatibility. The inverter has a 1A1C fast charging interface and two AC output interfaces, which can meet the needs of four devices at the same time.
Through dismantling, the charging head network learned that the core power components and control chips of this inverter are all domestic brands, and the inverter uses Xinhai Technology MCU to carry out sine wave output modulation and voltage and current display, the switch tube is from Silan Micro and Huarui Micro, and the internal capacitors are from Emerald. The power tube is equipped with a heat sink and is dissipated by a built-in cooling fan to reduce the temperature rise. The internal structure is compact and easy to carry, making it a very practical inverter.

MIJIA Mijia
Mijia 99W on-board inverter
Mijia's on-board inverter has a unique shape, the size of a can, in addition to AC output, it also comes with a USB module, which is convenient and practical.
The bottom of the car inverter is a soft rubber pad, there is a 220AC output socket on the top, and there are two USB output ports on the cover. The weight of the entire inverter is 612g.
Through disassembly, it is found that the modified wave inverter is not high-tech, it is a general component, and I believe that many people are very familiar with KA7500. Xiaomi's design of filling the inside of the inverter with thermally conductive glue greatly increases the reliability of the inverter, while the USB output provided by the inverter also increases the practicality of the inverter, which can also charge the phone when connected to AC power. The whole process was dismantled, and I sighed that this was the beginning of self-improvement of domestic products.

SMARTMI智米
Smart meter 100W on-board inverter
The smart meter inverter adopts a cube-shaped design, which is similar in appearance to a common USB multi-port charger. The input terminal is a gray cable with a car charger connector, and the output interface uses a 5-hole national standard jack, which is consistent with the household socket. In addition, there is also a USB port that supports QC3.0 fast charging, which can power most mobile devices or dash cams and car navigation systems.
Zhimi vehicle inverter is a product with good details, input fuse and sampling resistance to avoid the occurrence of input overcurrent. The thermistor near the transformer and primary switch detects the temperature, which is responsible for controlling the temperature of the fan while avoiding damage caused by excessive temperature of the components.
The addition of the internal fairing maximizes the effect of the cooling fan, so that the airflow can effectively cool the switch tube and transformer, and reduce the temperature rise under high load.

UGREEN
Greenlink 150W on-board inverter
This inverter has two AC output sockets and supports 150W output power. The 1A1C fast charging interface supports 30W output power and can power four devices at the same time. The inverter is powered by car charger input, with a 1.3-meter input line, and the inverter has a built-in digital display screen, which can display the working status in real time and know the battery voltage at all times.
Through the dismantling of the charging head network, it is learned that the inverter of this on-board inverter is composed of an inverter module, a fast charging module, a display panel and a cooling fan. The inverter module uses Huimang micro MCU for output modulation, and has a built-in MCU for power display and voltage display and other functions. The fast charging module adopts Yingjixin IP6538 for step-down conversion, and both interfaces support fast charging. The built-in cooling fan supports temperature control, which takes away the internal heat in time, and runs stably and reliably.

Summary of the charging head network
Through the dismantling and summary of the four on-board inverters, it can be seen that the four inverters all adopt a fashionable and modern appearance design, the body is small and easy to carry, and the body is equipped with an AC output socket and a fast charging socket for easy use. The inverter adopts a rectangular straight plate shape, and there is a digital display screen on the fuselage for voltage indication.
Baseus's inverter is designed with replaceable cables, which can be directly connected to the battery by replacing the battery clamp adapter cable to provide 500W output power. Both inverters are equipped with a fuse at the input for overcurrent protection and a thermistor to detect the temperature rise. There is a built-in cooling fan to enhance heat dissipation and meet the needs of long-term work.
