Our in-house PCBA workshop manufactures BMS control boards and inverter mainboards. Operators in anti-static garments assemble and inspect circuit boards on standardized production lines. AGV trolleys deliver materials automatically. Every PCBA must pass full functional testing before moving to the next process.

All circuit boards are double checked to avoid soldering defects and component missing, the foundation of stable power station performance.

Our automated cell sorting machine screens each LiFePO4 cell for voltage and internal resistance consistency. Only cells with matching parameters are grouped into battery packs, ensuring balanced performance and long cycle life across the entire pack.

Our automated laser welding station is used for battery pack assembly. The precise welding process ensures stable connection between cell tabs, reducing contact resistance and heat generation. It greatly improves the safety and consistency of the battery pack.

After BMS installation, each battery module undergoes insulation and high-voltage withstand test. We verify over-voltage, over-current, short-circuit and over-temperature protection functions to ensure the battery management system works reliably under all conditions.

Our engineering team conducts comprehensive functional testing on each unit — verifying AC output, DC ports, BMS protection, display accuracy and charging performance. Every product must pass full functional verification before entering the aging and packaging stages.

Finished power stations are tested in temperature-humidity chambers to simulate extreme hot and cold climates. Battery cycle testers run continuous charge-discharge cycles to verify long-term durability. These tests ensure stable performance for global outdoor and off-grid applications.

All finished portable power stations undergo continuous full-load aging testing on this automated system. The real-time monitoring platform tracks voltage, temperature and output status for every unit, filtering out potential defective products before shipment.

Products after passing all tests are neatly stored in our finished goods warehouse. We maintain standardized stock management to support flexible OEM & ODM orders and fast delivery for bulk clients.

Every unit follows a strict 6-step packaging procedure: bottom foam placement -> machine insertion -> top foam protection -> accessories & manual packing -> inner box sealing -> outer carton sealing. Custom-cut EPE foam fully protects the unit and accessories during long-distance sea and air transport, minimizing damage risk for global shipments.

Our finished portable power stations are packed with custom EPE foam to avoid damage during transit. Goods are neatly palletized and loaded into containers. We provide flexible shipping solutions for LCL and FCL orders, ensuring safe and on-time delivery worldwide.

The product is shipped using reliable courier services with tracking options available for all deliveries. Each package is carefully labeled with handling instructions and destination details to ensure safe and timely delivery. We offer various shipping methods including standard, expedited, and express shipping to accommodate different customer needs. All shipments undergo quality checks before dispatch to guarantee the product arrives in perfect condition.

Before shipment, every batch undergoes a final outgoing quality inspection. Our QC team randomly samples units to re-check appearance, packaging, labeling, output performance and accessory completeness. Only batches passing OQC are released for delivery.
