Shares of Erayak Power Solution Group Inc (NASDAQ:RAYA) rose 7% in premarket trading on Friday after the company reported a sharp jump in demand for its portable, low-noise inverter generators amid severe winter storms hitting the U.S. East Coast.
The power equipment maker said daily unit sales increased roughly twentyfold starting around January 20, 2026, compared with average levels in the weeks prior. As consumers prepared for potential power disruptions caused by extreme weather, the company shipped close to 1,000 generators over just two days.
The sudden surge in demand has tightened inventory availability in the U.S., leading Erayak to work closely with its supply chain partners to speed up restocking efforts through faster production cycles and prioritized logistics. The company cautioned, however, that inventory may remain constrained if harsh weather conditions continue.
Looking forward, Erayak plans to roll out additional home emergency power products in the first quarter of 2026. These include gasoline-powered inverter generators ranging from 4 kW to 13 kW, as well as multi-fuel generator models. The new offerings are expected to reach the U.S. market in the second quarter, subject to regulatory approvals and market conditions.
The company is also exploring opportunities to expand into related product categories that rely on power generation, potentially including pressure washers, electric or gas chainsaws, and camping-oriented equipment.
Erayak entered the U.S. market in 2024 and has continued to build momentum through online sales channels throughout 2025, according to CEO and Chairman Lingyi Kong.
