从China供应商批发进口315000mah 1008wh Portable Power Station — FOB条款

This 315000mAh 1008Wh portable power station from Shenzhen Zhongnengwei Technology Co., Ltd employs a lithium iron phosphate (Li lithium iron phosphate) 7S3P pack configuration at 22.4V nominal, delivering 1008Wh of stored energy with a pure sine wave AC output rated at 1200W continuous and 2400W peak surge capacity. The unit accepts DC input from 12-28V at up to 7.5A, enabling solar panel or vehicle-based recharging, and outputs at selectable 110V or 220V at 50/60Hz to suit regional requirements. The physical envelope measures 331 x 261 x 278mm, constructed from ABS+PC in grey or green finish options.

The LiFePO4 chemistry offers inherent thermal stability and cycle life advantages over NMC alternatives, with typical cell-level cycle life exceeding 2000-3000 cycles to 80% capacity retention, a standard expectation for this chemistry class. The 7S3P configuration implies seven series strings of three parallel cells, yielding the 22.4V nominal pack voltage with distributed current pathways for redundancy. ABS+PC housing provides impact resistance and moderate UV tolerance, though outdoor permanent exposure would require additional shelter per typical portable power station practice. The pure sine wave inverter topology ensures compatibility with sensitive electronic loads including medical devices, audio equipment, and inductive motor starting.

Target buyers include outdoor recreation operators, emergency preparedness coordinators, mobile medical clinics, and remote construction crews requiring silent, emissions-free power. The PD100W USB-C port supports laptop direct charging without AC inversion losses, while the dual 12V/10A cigarette lighter outputs suit compressor refrigerators and air pumps common in vehicle-based applications. Commercial buyers should confirm whether the unit carries UN38.3 lithium battery transport certification and IEC 62619 secondary battery safety compliance, as these are standard requirements for international shipment and commercial deployment but are not stated in the source data.

Shenzhen Zhongnengwei Technology Co., Ltd maintains both office and manufacturing facilities in Shenzhen's Longgang District, with the office located in Building D of Guanghongmeiju in the Hehua Community of Pinghu Street, and production housed at Building #3 of Xinligao Industrial Park on Shanxiashankeng in the same street. The supplier address data indicates a Harbor trust tier classification with no response rate recorded and zero average response hours, which suggests either a newly registered account or incomplete engagement metrics rather than active trading history. Buyers should treat response reliability as unverified and initiate contact to assess communication quality before committing to orders.

The company operates within China's dense Guangdong electronics manufacturing corridor, where vertical integration from cell sourcing through pack assembly is common but requires direct verification. The listing provides no stated certifications, factory audit data, or export license details, so buyers must independently confirm ISO 9001 quality management, ISO 14001 environmental compliance, or IEC 62619 battery safety certification if required for their market. The dual-address structure, office and factory, is standard for Shenzhen-based OEM/ODM operations, but the absence of stated R&D headcount, annual revenue, or named clients means due diligence should focus on sample evaluation and third-party inspection rather than inferred capability.
