KJ-641000W portable power station, 2009.6Wh LiFePO4 configuration
Product Summary
Model KJ-641000W is a portable power station designed for household emergency backup, camping, off-grid sites and mobile working power. The battery section uses LiFePO4 cells with a nominal voltage of 6.4Vdc, a rated capacity of 314Ah and 2009.6Wh of stored energy, so the unit can support longer supply periods than small-capacity units. The AC stage delivers a rated 1000W pure sine wave output at 185–230Vac / 50Hz, which is the waveform sensitive household appliances and electronic devices expect. Charging is handled either from the AC mains at up to 1000W maximum charging power, or from one solar panel in the 150–550W range through an MPPT window of 15–60Vdc. The unit measures L430×W296×H157mm at 20kg net weight and is rated IP21 for indoor installation.

Models and Options
This page covers the KJ-641000W configuration: 1000W pure sine wave AC output, 2009.6Wh LiFePO4 storage, one solar input and the DC / USB / Type-C port set listed above. For buyers who need a different port mix, casing print, retail packaging, firmware parameters, communication protocol or product configuration, these are handled through the manufacturer’s OEM/ODM program described in the Customization section. Cell type and structural safety components are fixed and not open to modification.
Materials and Structure
The battery is a LiFePO4 pack using a lithium iron phosphate cathode and graphite anode, housed in a steel / aluminum enclosure. The integrated portable body holds the battery section, the AC stage and the output panel in one unit, with a footprint of 430×296mm and a height of 157mm. Rated IP21 and specified for indoor installation, the unit is intended for dry, ventilated locations within -10°C to +50°C and 5%–95% non-condensing humidity at altitudes up to 2000m.

Applications
Home emergency backup: 1000W pure sine wave AC output keeps sensitive household devices supplied during outages.
Outdoor camping: 2009.6Wh of LiFePO4 energy supports lighting, small electronics and DC accessories on site.
Off-grid sites: one 150–550W solar panel feeds the MPPT input at 15–60Vdc for daytime recharging without mains power.
Mobile working power: DC, USB and Type-C ports let tools and devices be charged from one portable unit.
Customization
OEM/ODM support covers casing printing and coating, retail packaging, firmware parameters, communication protocols and product configuration. The standard workflow runs from requirement confirmation to solution design, sampling in 5–7 working days, certification adaptation, mass production and global delivery. MOQ starts from 100 units; lead time follows industry-standard schedules based on order volume. Cell type and structural safety components are not open to modification, to preserve safety and batch consistency.
