Erayak Power shares surge 41.03% premarket as demand for portable generators spikes amid U.S. East Coast winter storms.

Erayak Power Solution Group Inc. surged 41.03% 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 20-fold rise in daily unit sales over two days, driven by heightened consumer preparedness for power outages. This surge, coupled with CEO Lingyi Kong’s comments on strategic product expansion and capacity planning, signaled strong short-term demand and operational momentum. While other news mentioned leadership changes and market sentiment shifts, the direct catalyst for the premarket rally was the unexpected spike in orders tied to extreme weather conditions, which validated the company’s market positioning in home emergency power solutions.
