The annual "315" event has arrived again, and this year the China Consumers Association has determined the theme of consumer rights protection as "stimulating consumer vitality."
First, based on core responsibilities, promote collaborative governance for the protection of consumer rights, and create a safer and more reliable consumer environment.
Second, adhere to demand-oriented approaches, respond to the diversified trend of consumer demands, promote the improvement of consumer supply quality, and drive high-quality development.
Third, focus on addressing problems, identify key areas of focus, solve urgent difficulties, and promote the improvement of consumer quality.
As a high-tech enterprise specializing in battery technology application research, development, production, and sales, a national-level specialized and innovative "Little Giant" enterprise, a national intellectual property advantage enterprise, a drafting unit for industry standards, and a deputy team leader of drafting the Power Station Industry Standard in China, CARKU has remained consistent for 13 years, conducting business with integrity and always guided by consumer needs.
Built on the foundation of products, from research and development to testing, from manufacturing to equipment, from materials to supply, from production to warehousing, everything is treated with high standards and demanding requirements to ensure the outstanding quality of the products.
True capacity, not false advertising, is not an empty slogan but a solid responsibility.
Taking one of the CARKU jump starter as an example, with a labeled capacity of 16,000mAh, it has been officially tested at 17,841.6mAh, exceeding the labeled capacity by 1,841.6mAh.
Last year, the Guangdong Electronic Digital Industry Association Testing Center released an analysis of the "Comparison Test Results of Emergency Starter Power Supplies," which showed that in the mainstream market for mobile power supplies, the non-compliance rate reached 75%. Only two major brands, including CARKU, met the standards, with a consumer recommendation rating of five stars.
Recently, the warranty period has been extended from one year to two years! Making consumers feel more confident when placing orders!
CARKU genuinely puts consumers first in product research and design. From single product categories to multiple categories, it continuously breaks through and innovates, striving to provide consumers with better quality products and dedicating efforts to create products suitable for different fields, providing convenience to a wide range of users.
With a focus on responsibility, CARKU resolutely upholds the brand image and normal market order. The company promises not to engage in exaggerated false advertising, allowing consumers to easily purchase satisfactory goods and services and providing consumer satisfaction and peace of mind.
It's not just about "315," but also about "365." CARKU will continue to break through in quality management and industrial innovation, set benchmarks for the industry, and safeguard the "sense of safety" for car enthusiasts during their travels!
