What is a Solar Generator?
Before we jump into the best models, let’s clarify what a solar generator actually is. A solar generator is a portable power station that converts sunlight into electricity. It typically consists of solar panels, a battery, and an inverter. This nifty device allows you to harness the sun’s energy and use it to power your devices, from smartphones to small appliances.
How Does a Solar Generator Work?
At its core, a solar generator works by capturing sunlight through solar panels. This energy is then converted into electricity and stored in a battery. When you need power, the inverter converts the stored energy into usable AC or DC power. It’s like having a mini power plant right in your backpack!
