300W Portable Battery Power Station, 315Wh, 230V, USB-C PD

Portable battery power station with a capacity of 315 Wh.
It will support five devices simultaneously. The built-in AC converter with a pure sine wave with a rated power of 300 W (up to 600 W peak) will work, among other things, as an emergency power source. for the pump and controller of the central heating furnace, router, decoder or TV.
Three USB ports, including one USB-C with 60 W PD technology, will provide power and constant charging of a smartphone, tablet or laptop.
The 12 V socket will successfully power a travel refrigerator or special lighting.

Built-in power bank with 35 high-rate NMC/INR lithium-ion cells in 18650 housing with 3.6V nominal voltage and 2500mAh capacity (87500mAh in total).
The capacity does not fall below 80% of the initial value even after 500 full discharge cycles.
The cells are located in a durable basket with a structure that provides free air access to each cell, which greatly improves cooling efficiency.
Advanced BMS system that monitors all current parameters and cell temperature in real time, ensuring the safety of the charging and discharging process.
BMS has protection against overcurrent, short circuit, over-discharge, overcharge, overvoltage and overheating.
Cell balancing system extends the service life of the entire package.
Special USB-C port for cell block excitation – if we leave the station discharged to 0% for a long time and the device does not respond to the connected charger, then using a 5V, 2A power supply we can excite the cells and restore the operation of the station and BMS.
The station can be charged in three ways: from a power supply with a maximum power of 72W, from a car cigarette lighter cable or from external photovoltaic panels.
Manufactured in accordance with automotive standards.
