As 2024 transitions into 2025, CARKU successfully completed its two-week Winter Test Challenge in northern China. The testing team traveled to areas like Hailar, Genhe, and Mohe in Heilongjiang, where temperatures regularly drop below -30°C and sometimes reach -40°C.
Testing CARKU Heavy Duty Jump Starters and Heavy Truck Starting & Energy Storage Batteries, the team confirmed that these products performed excellently, consistently providing stable power and successfully starting trucks even in extreme cold. This success has earned high praise from truck drivers and solidified reputation of CARKU for reliability and quality.
CARKU Founder Cloud Lei emphasized the importance of real-world testing in extreme cold. “Starting heavy trucks in temperatures as low as -40°C is a global challenge,” he said. The winter tests allow the R&D team to engage directly with users, gather valuable feedback, and optimize product design and performance for better market reliability.
