Meta description:Meet Shenzhen Yunrui Intelligent Equipment — a high-tech manufacturer of portable and wallbox AC EV chargers, charging PCBA solutions, and testing systems, serving global OEM/ODM customers since 2013.
A Decade of Engineering, a Decade of Charging
Shenzhen Yunrui Intelligent Equipment Co., Ltd. is a high-tech enterprise specializing in the design, development, production, and sales of high-end electronic products. Founded in 2013 — originally as Shenzhen Yunxu Automation Engineering Co., Ltd. — and headquartered in Longgang Central City, Shenzhen, the company has grown from a precision electronics workshop into a globally focused supplier of AC electric vehicle (EV) charging equipment.
Guided by our Chief Design Engineer, Mr. Li Yanggui, our team has developed dozens of products and secured dozens of patents. That foundation in core electronics is what allows us to move quickly from a customer's idea to a certified, mass-produced charging product.
In 2020, Yunrui Intelligent formally entered the new energy industry. Since then, we have focused our engineering strength on one clear goal: becoming a world-class solution provider for AC charging.
What We Build
Our portfolio covers the full AC charging chain, from the components inside the box to the finished product on the wall:
- Portable AC EV chargers
- Wallbox AC EV chargers
- Charging cables and extension cables
- Charging PCBA solutions
- Production and test equipment
- Grounding safety modules
Our chargers operate across an input range of 90V–270V and deliver output power from 3.5 kW to 22 kW. They are compatible with Tesla charging piles rated at 32A, 40A, 48A, 63A, and 80A.
One-Stop OEM and ODM
For brands, distributors, and installers, speed to market matters. Yunrui Intelligent offers genuine one-stop OEM and ODM services — from industrial design and electrical architecture to firmware, certification support, and volume manufacturing. Because our PCBA know-how lives in-house, we can adapt, re-spec, and re-certify a platform faster than a company that outsources its electronics.
Whether you need a private-label portable charger for a European retailer or a customized wallbox for a North American fleet, we can take the project from specification to shipment.
Quality Is a System, Not a Slogan
Our products are built around the design philosophy of high quality, high efficiency, and cost-effectiveness. In practice, that means rigorous protection and testing built into every unit:
- Over-voltage, under-voltage, and over-current protection
- Grounding protection and leakage protection (RCD, AC 30 mA + DC 6 mA)
- Lightning protection, flame-retardant materials, and intelligent temperature control
- Efficiency of ≥98% and insulation resistance of ≥10 MΩ
- Wide operating temperature range of −35 °C to 85 °C, and storage from −50 °C to 85 °C
- IP54 protection for portable and wallbox units, and IP65 for charging cables
- Tested across high, low, and normal temperature environments for more than 1,500 cycles
Our team of 10 R&D engineers, 10 quality-control specialists, 5 international sales engineers, and 60 production workers keeps design, quality, and production tightly connected — so issues are caught on the line, not in the field.
Certified for Global Markets
Every major market has its own charging standard, and shipping the wrong one means a product that simply cannot be sold. Yunrui Intelligent builds products certified for each:
- China (GB/T):
- Europe (IEC/EN):
- United States (SAE):
- Tesla (NACS):
That breadth means one partner can serve customers in Europe, North America, and Asia — with products built to the right standard from day one.
Our Commitment
The shift to electric mobility depends on charging that is safe, reliable, and affordable. Yunrui Intelligent exists to make that possible for the companies building the charging networks of tomorrow. If you are looking for a manufacturing partner who understands both electronics and certification, we would be glad to talk.
