Recently, the CARKU test team carried a variety of starting power supplies for extreme cold tests in Erlianhot, Inner Mongolia. In low temperature environments, they tested the starting performance, functional output, reliability and safety of the car’s emergency starting power supply all day and under various models. Actual data and experience have proved the quality of CARKU's power supply.
Difficulty Starting The Car In Winter
Normally you may think it is so easy to start a car, but everything is not that simple in winter. For cars, low temperature has the greatest impact on the battery. The charging and discharging capacity of the battery is greatly reduced. When the temperature is too low, the current released by the battery will not reach the starting amount, which will cause the car to start difficult.
CARKU's powerful start-up power supply can solve this problem, but it sets higher standards for its performance. We know that with the fierce market competition, product quality has gradually become the core competitive advantage, and the adaptability of the emergency starter power supply in extreme cold environments is an important factor to test its quality, so it needs to be tested at low temperatures in winter .
No Fear Of The Sub-35 ℃ High Cold
In order to ensure the results of the extreme cold test, this time we specially selected Erenhot, Inner Mongolia, as the test site. Erenhot City is located at the northwestern end of Xilin Gol League. The temperature was greatly reduced due to the influence of cold air. The lowest temperature reached minus 35°C. This not only created natural power for emergency start-up power. The test environment also increases the difficulty of the test team and product testing.

In addition, R&D personnel also tested the tire pressure inflation function and input/output performance of the emergency start power supply.
The start-up test of different models at different times is not only to effectively test the product, but also to provide reliable data reference in the later product development process, but also to relieve customers' "anxiety" about low temperature battery life.
It is worth mentioning that, despite the extreme harsh environment for several consecutive days, the Karcool test team performed well and successfully completed the testing of the power supply.

The successful completion of this test once again demonstrated the strong strength of CARKU's product research and development, laying a solid foundation for creating innovative products, and also showing CARKU's firm determination to provide customers with high-quality products and services as the main force in the field of lithium emergency power supplies.
In the future, CARKU will uphold the spirit of innovation, provide customers with the highest quality solutions and products, and provide customers with a 100% guarantee for smooth travel.
