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.
