The portable power station has outstanding features. It supplies pure sine wave power in smooth waves, vital for protecting your costly electronics, unlike the chunky square waves of modified sine wave power. The built-in BMS guards against overload, overcharge (auto-stops when full), and short circuits. Multiple fans keep it cool. With solar charging and an MPPT controller, it charges fast from solar panels, optimizing power use. It also supports pass-through charging (except AC output), letting you use it while charging.
