Erayak Power Solution Group is a China-based manufacturer of portable power products sold primarily to customers in North America, Europe, and China. The company operates through its core subsidiary, Zhejiang Leiya, based in Wenzhou, which designs and manufactures five product categories: inverter generators (gasoline-powered, 1kW–15kW), DC-to-AC inverters (100W–15,000W), hybrid inverters and energy storage systems, portable power stations, and smart battery chargers. In FY2025, inverters accounted for roughly 48% of revenue, gasoline generators ~42%, portable power stations ~8%, and chargers ~1%. Erayak sells through two channels: retail e-commerce, primarily Amazon in the U.S. and Europe, and wholesale built-to-order (BOT) contracts with customers such as Einhell Germany and Canadian Tire. Under the BOT model, Erayak only procures raw materials after customer confirmation, limiting inventory risk. Costs are driven by electronic components, engines, batteries, and factory labor. Erayak leases its roughly 36,000 square meter manufacturing facility in Wenzhou through 2037 and benefits from a preferential corporate tax rate as a recognized high-tech enterprise in China. The company holds international certifications including FCC, CE, ETL, and TÜV, which are required to access North American and European markets. Erayak's growth strategy focuses on geographic expansion — including a new U.S. subsidiary, Nexora Group — and product development toward hybrid generators, IoT-enabled energy management, and emissions-compliant technology.
