    Yes, a solar generator can be used while charging. This feature is known as pass-through charging. Do any Solar generators/Power station allow charge and use at the same time? Do any Solar generators/Power station allow charge and use at the same time? Does anyone know of anything that can both charge and provide power at the same time? Thanks. Many wonder if they can. Solar generators are self-contained portable power systems made up of three essential components: Solar panels – collect sunlight and convert it to DC power. Solar panels capture sunlight, converting it to DC electricity, which is then stored in the internal battery. I've tested numerous solar generators over the past three years and found that approximately 70% of current models support simultaneous.
