Explore our top-tier manufacturing lines, from high-capacity backup batteries to specialized medical-grade and industrial power supplies.
ELITE POWER is a wholly-owned subsidiary of GRACE DEVELOPERS CO., LIMITED. Strategically operating branches in key manufacturing hubs—Hong Kong, Shenzhen, and Dongguan, China—we represent a premium, high-technology energy production enterprise integrating scientific research, product design, precise manufacturing, and global sales.
We focus heavily on intelligent green new energy storage solutions. Our production ecosystem is certified under both ISO:9001:2015 and ISO14001:2015 quality and environmental management systems. Beyond 20000mAh solar power banks, our state-of-the-art capability extends to household energy storage systems, commercial energy storage cabinets, containerized storage, emergency automotive systems, and advanced power management solutions.
In 2022, ELITE POWER signed a strategic cooperation agreement with tier-one partners in the USA. This alliance accelerates our development of optical storage and charging systems in the United States, facilitating the deployment of residential home batteries, heavy-duty truck parking battery innovations, and off-grid mobile solar reserves.
The foundation of our relationships with global industrial buyers and supply chain networks.
We operate with honesty, strict integrity, and corporate transparency in all global business dealings.
We push the boundaries of renewable energy technology to engineer a sustainable, zero-emission future.
We strive for engineering excellence in everything, from custom PCB design to global customer support.
We actively build robust long-term alliances that deliver technical and economic value to our global partners.
Through extensive material sourcing across the Pearl River Delta and advanced SMT production lines, ELITE POWER ensures that every custom 20000mAh solar power bank achieves optimized solar conversion, precise BMS safety parameters, and maximum cycle life.

For global buyers, retail distributors, and outdoor supply brands, the 20000mAh capacity segment stands as the gold standard of mobile power solutions. This capacity holds sufficient power density to recharge modern smartphones 4 to 6 times, or provide off-grid operational runtimes to laptops, communication devices, and tablets.
When engineered with integrated solar recharge panels, a 20000mAh unit becomes an independent emergency energy asset. Enterprise purchasers must evaluate energy densities, standard discharge profiles, and conversion rates rather than simple surface capacity metrics. Working directly with a certified manufacturer like ELITE POWER guarantees that internal Lithium-Polymer cells deliver real, verified capacities instead of inflated labels commonly found in lower-tier markets.
Sourcing directly from our facilities in Shenzhen and Dongguan leverages the world's most dense electrochemical and raw material supply chain:
We utilize premium monocrystalline silicon solar cells, achieving up to 22.5% photovoltaic conversion efficiency. This ensures maximum current generation even under low-light or overcast conditions.
Our advanced PCBA protects the cell chemistry from thermal runaway, overvoltage spikes, and depth-of-discharge degradation, vastly extending the service life of the power bank.
Engineered to withstand extreme environments, our outer shells incorporate shock-absorbing TPU armor, sealed port flaps, and dustproof seals to prevent moisture ingress.
High-capacity solar chargers are not only retail consumer goods; they serve vital roles in commercial and localized enterprise applications:
Shipping large Lithium-Polymer battery capacities (20000mAh / 74Wh) requires deep knowledge of air and maritime shipping restrictions. As a professional OEM/ODM manufacturer, ELITE POWER ensures complete conformance to global regulatory schemes:
Our manufacturing processes comply with UN38.3 safety standards (ensuring safety during vacuum thermal cycling, vibration, shock, and external short-circuits) and maintain updated MSDS (Material Safety Data Sheets). Furthermore, we ensure all units feature the necessary certifications for target markets, including UL2056, CE, FCC, and RoHS compliance, reducing customs clearance issues and commercial liability risks for our partners.
ELITE POWER is committed to continuous R&D. We are currently integrating Gallium Nitride (GaN) components to decrease internal heat generation while supporting ultra-fast 45W and 65W Power Delivery (PD) protocols. Concurrently, our engineering team is researching lightweight, flexible thin-film solar overlays to increase solar conversion surfaces without increasing the device footprint.
