Smartmi is a company focusing on smart home appliances within the Xiaomi ecological chain, with products covering multiple brands such as air purifiers, electric heaters, and electric fans, focusing on intelligent control functions. The enterprises in the ecological chain are independent operating companies invested by Xiaomi, and there is no affiliation with Xiaomi, so there is often a situation where Xiaomi (Mijia) products compete with the same products in the ecological chain.
 
Zhimi on-board inverter and Mijia on-board inverter were released almost at the same time, in order to add waves to the mixed on-board inverter market, and seize the automotive accessories market as an emerging Internet brand, but unfortunately the two did not open the gap in product positioning, both chose the main cost-effective modified sine wave inverter, and the power also chose a relatively similar 100W, the high degree of overlap in the positioning of the two has caused a serious pile of target users, and the appearance design is better, The lower-priced Xiaomi car inverter emerged as the ultimate winner.
 
In fact, the performance of the smart meter vehicle inverter is good, the appearance is simple, the volume control is also good, the surface is made of high-quality V0 flame retardant material PC/ABS, high temperature resistance, ultraviolet resistance, the material selection is fully in line with RoHS environmental protection certification, the workmanship is also solid, and it belongs to the upper level in the industry. It has a five-hole national standard socket, as well as a USB socket that supports QC3.0 fast charging, but because the USB socket and the AC jack are located in the same plane, if a relatively large plug is inserted, it will block the USB socket and even the heat dissipation hole, which is much inferior to the Xiaomi car inverter.
 
Due to the use of traditional plastic shells, the smart meter car inverter can not adopt a fanless design, and it also lags behind Xiaomi in terms of noise control, and the price performance of 229 yuan is also relatively average.
