Explore our engineering-grade product lines designed for medical, smart home, industrial, and consumer electronics applications worldwide.
ELITE POWER is a subsidiary of GRACE DEVELOPERS CO., LIMITED, strategically headquartered with branches in Hong Kong, Shenzhen, and Dongguan, China. We operate at the intersection of power topology design and advanced manufacturing, serving as a global new energy enterprise integrating scientific research, design, manufacturing, and sales.
Our focus is centered on intelligent green energy solutions. Driven by strict engineering standards, we specialize in high-efficiency home energy storage systems, industrial and commercial energy storage cabinets, containerized energy storage units, supercapacitor vehicle jump starters, portable power stations, and custom lithium-ion battery modules (including truck starter systems and specialized furniture power packs).
By leveraging the combined technological intelligence of the Pearl River Delta’s high-tech manufacturing corridors, we ensure that every universal power adapter, medical power supply, and energy storage unit exceeds global safety and efficiency expectations.
These values define our business relationships, design choices, and manufacturing processes.
We operate with complete honesty, total traceability, and absolute transparency in all business dealings.
Committed to pushing boundaries of power electronics and renewable storage for a greener future.
We strive for perfection in every action, from early product development to customer after-sales support.
We believe mutual cooperation and shared growth are key factors for long-term global partnerships.
The global power adapter market is undergoing a technology shift, transitioning from silicon (Si) to wide-bandgap (WBG) semiconductors, primarily Gallium Nitride (GaN) and Silicon Carbide (SiC). This development is reshuffling manufacturing architectures globally, forcing wholesale universal power adapter factories to invest in higher thermal dissipation technologies and high-frequency magnetics.
GaN adapters allow up to 3x power density increases, reducing package size by 40% while maintaining thermal levels well below international regulatory limits. Modern switching topologies like Active Clamp Flyback (ACF) and Resonant LLC converters are becoming standard in premium OEM designs, minimizing switching losses and delivering efficiencies upwards of 94% under full-load conditions.
Concurrently, the rapid adoption of USB Power Delivery (USB PD 3.1 & Extended Power Range) is consolidating disparate industrial and consumer charging protocols. The EPR framework allows power configurations up to 240W over a single USB-C cable, enabling universal power adapters to serve laptops, heavy industrial test equipment, IoT gateways, and medical devices.
Enterprise procurement teams in North America, Europe, and the APAC region require supplier compliance and verified product reliability metrics. Standard procurement protocols are no longer based solely on FOB unit costs; total cost of ownership (TCO), Mean Time Between Failures (MTBF) calculations, and thermal profiles now dictate sourcing decisions.
Critical certifications required for market entry include:
Operating out of Dongguan and Shenzhen, China’s industrial clusters, ELITE POWER leverages a robust, vertically integrated component ecosystem. Our proximity to premium raw material suppliers (high-frequency transformers, specialized planar magnetic components, high-temperature capacitors) dramatically reduces design cycles and product delivery lead times.
Under our ISO 9001:2015 and ISO 14001:2015 certified quality management systems, our factories utilize Industry 4.0 automation. Our manufacturing pipelines include:
This localized supply chain structure provides high resilience against global logistics volatility, allowing ELITE POWER to adjust manufacturing outputs quickly to match changing demand cycles in North America and Europe.
To meet the diverse demands of modern energy markets, our design team builds distinct structural solutions across our primary product categories:
Medical power modules must operate without interference in critical environments. Our medical power supplies utilize dual-stage EMI filters to meet EN55011 Class B radiated emissions standards. The integration of high-grade optocouplers and creepage distances exceeding 8mm ensures galvanic isolation up to 4,000 VAC, protecting patients and medical personnel.
Built for embedded systems, telecommunications, and industrial automation control, our open-frame configurations offer convection cooling solutions. They are designed with wide input voltage ranges (85V AC to 264V AC) to handle unstable industrial grid conditions, maintaining full functionality during temporary voltage drops.
Designed for integration into smart furniture systems, these battery packs include active Battery Management Systems (BMS). Features include over-current protection (OCP), short-circuit protection (SCP), and over-temperature cut-offs (OTP). High-density lithium chemistry provides long lifespans (500+ cycles at 80% DoD) for reliable, long-term power delivery in home applications.
These modular solutions utilize safe Lithium Iron Phosphate (LiFePO4) chemistry. The 19.2kWh US Standard stackable home energy storage system interfaces with solar arrays and hybrid inverters, supporting peak-shaving and backup applications. For utility-scale installations, our 1MWh to 2MWh Energy Storage Containers feature active liquid cooling, automated fire suppression, and cloud-connected telemetry systems.
We maintain high quality control standards at every step of development, from initial engineering design to final product delivery.
We have obtained ISO:9001:2015 and ISO14001:2015 quality management and environmental systems certifications, ensuring all production procedures are fully traceable.
In 2022, we signed a strategic cooperation agreement with USA partners to develop the optical storage and charging system market in the US, focusing on home energy storage and vehicle battery emergency systems.
Each unit undergoes multiple inspection stages, including in-circuit testing, automated optical inspection, and full-load burn-in testing to ensure reliable operation.
Our sales and logistics network spans Hong Kong, Shenzhen, and Dongguan, enabling efficient shipping, custom compliance management, and technical support.
Find answers to common questions about customization, global compliance, and procurement options.
For custom ODM power projects, the typical cycle is 4 to 6 weeks for design approval and prototyping, followed by 3 to 4 weeks for mass production. Standard OEM designs with existing certifications can be produced within 15 to 25 working days, depending on order size and component supply.
Our medical power supplies (24W to 50.4W) are certified to IEC 60601-1 and ANSI/AAMI ES60601-1 standards. They feature 2xMOPP insulation barriers and undergo insulation resistance tests to limit leakage current to safe levels for patient-connected systems.
We use Lithium Iron Phosphate (LiFePO4) chemistry for all home and industrial energy storage systems. LiFePO4 offers excellent thermal stability, safety, and a long cycle life (over 6000 cycles at 80% Depth of Discharge) compared to standard ternary lithium chemistries.
Yes. Our 2500mAh and 5000mAh battery packs are customizable. We can modify the dimensions, connector profiles, integration protocols, and Battery Management System (BMS) software to match the design of your smart furniture products.
Yes, we cooperate with third-party testing agencies like TÜV SÜD, UL, SGS, and Intertek. We can coordinate the application process for local safety and efficiency certifications (such as CE, FCC, UL, KC, PSE, and RCM) for your custom power supply products.
