Hangzhou ChengYingYi Energy Technology Co.,Ltd

Hangzhou ChengYingYi Energy Technology Co., Ltd. offers a full range of energy storage and gas handling solutions, including storage tanks, portable oxygen cylinder kits, and separation equipment — ideal for industrial and medical applications. Being based in Hangzhou, China, gives them access to strong manufacturing capabilities and logistics networks in eastern China. Founded in 2014, the company has been active for nearly a decade, which suggests stability and experience in the market. However, no work email, phone number, or business documents have been verified — this raises concerns about legitimacy and responsiveness. Buyers should request additional verification before placing large orders or sharing sensitive requirements. The lack of verification may make it harder to build trust with new international partners. Having a clear product range helps buyers identify potential use cases, but due to missing verification, due diligence is essential before engagement.
