Erayak Power shares surge 35.16% premarket following surge in demand for portable generators amid U.S. East Coast winter storms.

Erayak Power Solution Group Inc. (NASDAQ: RAYA) surged 35.16% in premarket trading following a sharp increase in demand for its portable quiet inverter generators amid severe winter storms on the U.S. East Coast. The company reported a more than 20-fold rise in daily unit sales over two days, with shipments nearing 1,000 units, driven by consumer preparedness for power outages. This surge, attributed to heightened grid reliability concerns, has strained U.S. inventory levels, prompting accelerated production and logistics efforts. The stock’s movement aligns directly with this news, which highlights immediate operational momentum and market validation of its product demand. While other reports referenced leadership changes and market sentiment, the concrete surge in sales tied to weather-related demand was the most proximate and impactful catalyst.
