Inside CE-LINK’s Portable Power Ecosystem: From Inverters to Industrial Scale
Executive Overview: CE-LINK’s Expansion into Portable Energy
Established in 2004 and listed on the Shenzhen Stock Exchange in 2019 (Stock Code: 300787), CE LINK LIMITED has expanded its contract manufacturing footprint from signal cables, adapters, and power accessories into commercial and consumer energy storage systems. Backed by over 10,000 employees, 500+ R&D personnel, and a network of seven production campuses across China (Dongguan, Jiangxi) and Vietnam (Hai Duong, Bac Giang), the company operates as a vertically integrated OEM/ODM provider.
The manufacturer’s portable power lineup spans capacities from 102.4Wh to 5,120Wh and continuous inverter power ratings from 200W to 4,000W. Supported by in-house cell preparation, automated SMT lines, module assembly, and certified testing facilities—including SGS Accredited Laboratory and TÜV NORD Witnessed Laboratory credentials—the product catalog targets off-grid power, recreational vehicle (RV) electrical systems, residential energy backup, and emergency uninterrupted power supply (UPS) applications.
Architectural & Technical Foundations

Battery Chemistry and Lifecycle Metrics
The product line relies entirely on Lithium Iron Phosphate (LiFePO4) chemistry. Heavy-duty configurations utilize aluminum-cased prismatic cells, such as the proprietary BC100 100Ah 3.2V cell rated for ≥ 3,500 cycles to 80% state of health (SOH). Mid-tier and lightweight entry units use cylindrical steel-cased LiFePO4 cells rated between 3,000 and 4,000 cycles at 95% depth of discharge (DOD) under testing parameters. Thermal tolerances for all platforms operate within an operational discharge window of -20°C to 45°C (charge window: 0°C to 45°C).
Inverter & Charging Infrastructure
Across the portable series, high-capacity models incorporate bidirectional inverter topology. This design removes the need for external AC brick adapters, allowing users to plug directly into high-draw mains lines. Fast-charging capabilities achieve full depletion-to-100% recharging in as low as 1.6 hours. System logic pairs bidirectional inverter hardware with pure sine wave output, auto-switching AC bypass architecture, and grid-synchronizing frequency controls (50Hz/60Hz).
Uninterruptible Power Supply (UPS) Integration
Units such as the PS3000 carry UL1778 certification, providing transfer times under 14 milliseconds during grid power failures. The built-in bypass relay directly routes utility current to critical loads under normal grid conditions; the internal inverter takes over within 14ms upon power interruption without disconnecting connected hardware.
Modular Expandability & Enclosure Design
Larger systems integrate proprietary multi-pack expansion buses. Base units can tether up to six auxiliary battery packs (e.g., PB2560 modules), enabling capacity expansions up to 17,500Wh. Structurally, systems in the 1.8kW–4kW tiers incorporate internal aluminum-alloy chassis framing, pull-out luggage handles (tie rods), and heavy-duty transport wheels to handle weights ranging from 11.6 kg up to 34+ kg.
