Providing compliant, high-efficiency automotive power solutions customized for Vietnam's rapidly rising smart transportation and logistics infrastructure.
Vietnam is undergoing a major industrial shift. Driven by high smartphone adoption rates, urbanization in Hanoi and Ho Chi Minh City, and a booming ride-hailing and e-commerce logistics sector (led by Grab, Be, and Shopee Express), the demand for high-efficiency, durable power accessories has reached an all-time high.
Furthermore, Vietnam's automotive sector is expanding rapidly. The domestic automotive fleet, combined with a significant push toward electric vehicles (EVs), calls for specialized internal power distribution solutions. In-vehicle accessories must handle variable voltage ranges (12V–24V) while maintaining high conversion efficiency to prevent heat buildup—especially in Vietnam's tropical climate where ambient temperatures often exceed 38°C.
As a leading charger manufacturer, we design our products to withstand these severe operating conditions. We use premium grade PCB components, intelligent cooling, and ABS flame-retardant enclosures to ensure longevity and safety for everyday commuters and commercial logistics fleets alike.
Our Advanced Power Manufacturing Hub
Established in August 2010, Shenzhen FuYun (RUIYU) Technology Co., Ltd. is located in the Guangming New District of Shenzhen, China. Over the last decade, we have grown into a top-tier manufacturing hub, specializing in the research, development, production, and sales of power adapters, car chargers, and high-precision core components.
Spanning a massive 50,000 m² modern facility, our factory houses 48 active production lines run by more than 800 skilled workers and a dedicated team of over 30 management experts. This robust setup allows us to reach a daily production capacity of 100,000 units, keeping our turnaround times between 15 and 20 days.
Helping regional brands and commercial fleets stand out with bespoke designs, premium components, and strict compliance.
Our chargers feature smart IC technology that auto-detects connected devices to deliver the optimal current. This protects phone batteries from overcharging and excessive heat, even during long commutes.
Engineered for Southeast Asian climates, our chargers use high-grade ABS+PC polymer shells and efficient heat dissipation layers to operate reliably under high cabin temperatures.
Designed with input over-voltage protection (OVP), under-voltage lockout (UVLO), output over-current protection (OCP), and short-circuit protection (SCP) to safeguard vehicle electronics.
Reliable supply chains, swift deliveries, and custom-branded packaging.
As a leading supplier to the USA, EU, Japan, South Korea, and Southeast Asian markets, we understand the logistical and technical requirements of importing goods into Vietnam. Our standard order fulfillment time is 15 days once your PO is confirmed, helping you maintain lean inventory levels.
