300W Portable Battery Backup Power Station For Continuous Power
Supply
The 300W portable power station is your reliable guardian. It
provides pure sine wave power, ideal for pricey, fragile
electronics, unlike harmful square waves. Its smart BMS prevents
overloads, overcharges (auto-off at full), and short circuits.
Multiple fans cool it. With an MPPT controller, it efficiently
harnesses solar power and allows use while charging (except AC),
like powering a fridge with a solar panel.
