Product Description

300W High Capacity Backup Battery Power Station For Outdoor Use

The 300W portable power station is your reliable protector. It provides pure sine wave power, ideal for fragile electronics, unlike harmful square waves. Its smart BMS prevents overloads, overcharging (auto-off at full), and short circuits. Multiple fans cool it. With an MPPT controller, it efficiently uses solar power. You can use it while charging (except AC), like powering a fridge with a solar panel.
