Application situation:
Standby Generators for power outages
What is a portable power station?
A portable power station is a generator powered by a rechargeable battery. Equipped with an AC outlet, DC carport, and USB charging ports,
they can keep all your gear charged, from smartphones, tablets, laptops, to CPAPs and small devices, like a fan, mini coolers, electric blankets, etc.
How does a portable power station work?
In fact, it is a DC to AC inverter that increases the DC voltage and then changes it to AC before sending it out to power a device, like your laptop and TV.
The DC input port collects and stores electricity / energy from an AC outlet or solar panel and outputs via built-in USB ports, DC carport or AC outlet
