Combining fluid simulation and mold flow analysis, the R&D team customizes a dedicated air duct heat dissipation structure to build a full-range three-dimensional heat dissipation channel, accurately guiding and discharging heat generated by inverter and cell operation, avoiding heat accumulation, effectively reducing temperature rise under high-load operation, and eliminating hidden dangers such as high-temperature power reduction and thermal runaway. Meanwhile, it is equipped with multiple active safety protection mechanisms, integrating overvoltage, undervoltage, overcurrent, short circuit, overload, high temperature and low temperature protection functions, covering the whole working scenarios of charging, discharging, standby, fast charging and inversion. Aiming at outdoor environments with rain, dust and alternating high and low temperatures, the sealed structure and material selection are optimized to improve the overall weather resistance, enabling stable start and operation in a wide temperature range and adapting to complex and variable outdoor working conditions.

The whole machine integrates multi-interface intelligent time-sharing power supply logic, with independent control of AC, DC, Type-C and USB multi-channels, supporting simultaneous multi-channel output without mutual interference, solving the problems of power attenuation and interface mutual interference when multiple ports of traditional devices are turned on simultaneously. The whole R&D process passes strict reliability tests including high and low temperature cycling, full-load aging, shock vibration and short-circuit fault tolerance to calibrate all performance parameters. With self-developed circuit architecture, reliable safety system and full-range scenario adaptability, the 1200W power station achieves all-round upgrades in performance, safety and durability, providing a stable, pure and safe high-power energy storage solution for outdoor operations, household emergency use, field camping and mobile power supply scenarios.
