Explore our premium grade power conversion systems engineered for micro-mobility, automotive, and industrial operations.
Leading the Power Electronics Industry with Two Decades of Technological Excellence.
Established in 2001, Shenzhen E-Tronde Charger Co., Ltd. specializes in the design, engineering, and manufacturing of advanced battery chargers and power supply products. Over the last twenty years, the company has grown into a leading innovator in power electronics, delivering high-efficiency charging systems to global micro-mobility networks, logistics fleets, and consumer electronics distributors.
Equipped with state-of-the-art facilities, our factory includes dedicated SMT (Surface-Mount Technology) lines, automated through-hole assembly setups, and a highly specialized automated transformer production workshop. This level of vertical integration guarantees exceptional component quality control and stable supply chain delivery times.
Our experienced R&D engineering team drives innovation by designing custom charging profiles, advanced thermal management structures, and multiple safety protections (OCP, OVP, OTP, SCP). We ensure that every product meets global compliance standards, enabling international buyers to scale their operations securely.
Insights into the rapid technological shift shaping micro-mobility power management and infrastructure deployment.
The industry is moving quickly away from old-style Silicon components to Gallium Nitride (GaN). This shift reduces the size of chargers by up to 40% while achieving over 95% efficiency. It also significantly lowers thermal generation in high-power lithium battery chargers.
Modern electric vehicles and e-scooters require constant communication between the charger and the Battery Management System (BMS). Using CAN bus or UART protocols, our chargers dynamically adjust voltage and current based on battery health to ensure safe operation.
Shared micro-mobility networks and outdoor charging stations require high protection ratings. Modern chargers need IP65 or IP67 ratings to withstand dust, rain, and humidity, ensuring long-term operational uptime and low maintenance costs.
The global shift toward micro-mobility is driving unprecedented demand for highly efficient, smart charging systems. E-scooter fleets, electric bikes, and light electric vehicles (LEVs) are no longer powered by standard consumer adapters. Instead, modern fleets rely on heavy-duty charging infrastructure designed for 24/7 reliability.
As battery capacities increase to extend operational range, charging speed has become a key competitive advantage. Our latest chargers utilize smart three-stage charging (CC-CV-Float) algorithms to safely accelerate charge times while preventing overcharging and cell degradation. Additionally, active power factor correction (PFC) is built into our high-power lines to reduce energy loss and meet strict international power grid requirements.
For B2B buyers, fleet operators, and industrial enterprises, importing battery chargers involves managing technical risks, verifying production quality, and ensuring regulatory compliance. The sourcing process requires selecting partners that can deliver consistent quality across production batches.
Shenzhen E-Tronde Charger Co., Ltd. addresses enterprise pain points by providing certified, high-performance charging systems. Our specialized engineers work closely with B2B clients to customize electrical specs, enclosure branding, and cable layouts.
Every production unit undergoes strict high-voltage, load, and thermal burn-in tests.
Comprehensive export capabilities with optimized shipping support for Europe, the Americas, and Southeast Asia.
Combining automated SMT lines, advanced quality assurance, and direct component sourcing to deliver highly competitive production cycles.
By using automated surface mount technology, we achieve precise placement of sub-millimeter components, reducing solder defects and ensuring consistency across large production runs.
Our dedicated, automated transformer winding workshop allows us to customize power conversion efficiency and maintain tight control over core components.
All finished products undergo multi-stage testing, including automated optical inspection (AOI), full-load burn-in, and electrical isolation tests before shipment.
Operating a 10,000+ square meter factory in Shenzhen allows E-Tronde to leverage the world's most complete hardware supply chain ecosystem. From prototype development to high-volume manufacturing, our processes are designed to maximize efficiency and minimize lead times.
By producing our own transformers and managing assembly in-house, we eliminate typical subcontractor delays. This manufacturing model ensures E-Tronde can scale production to meet seasonal demand changes and provide reliable lead times for international distributors.
Our high-performance charging systems are designed to operate reliably across a wide range of environments.
Municipal shared e-scooter and e-bike networks operate in demanding outdoor environments. Our weather-resistant, dust-proof charging options (including IP67-rated models) can be integrated directly into charging docks or urban hub setups to maintain consistent fleet availability.
Warehouse material handling equipment, automated guided vehicles (AGVs), and heavy-duty logistics trucks require reliable, high-power charging systems. Our 320kW charging stations are engineered to support fast turnaround times for heavy-duty industrial vehicles.
For outdoor recreation, camping, and remote environments, our portable, water-resistant solar panels and compact folding chargers offer reliable off-grid power to keep devices and light electric vehicles charged wherever you go.
Last-mile delivery operations require scalable, reliable power management. Our multi-port smart battery chargers allow fleet managers to charge multiple batteries simultaneously, with integrated safety protections to prevent electrical overloads.
