In 2016, we officially set sail; in 2022, we merged with ZMI's core team. The "CUK" (/kʊk/) in CUKTECH represents the recognition of the Čuk circuit, a special type of DC-DC circuit topology proposed by Slobodan Čuk in 1976. The CUK circuit's high efficiency, low ripple, and flexibility align perfectly with the modern demand for efficient energy utilization.
CUKTECH began as an OEM company and has been focused on developing chargers and power banks for many years. Our clients include international tech giants like LG, Hitachi, and XIAOMI. Our core team has also managed ZMI's operations for a decade and has built a reputation for high quality. Currently, more than 70% of the CUKTECH team is dedicated to R&D and Quality Assurance. Our team has shipped over 150 million units of power banks and more than 20 million chargers under CUKTECH&ZMI, serving brands like XIAOMI, LG, and Hitachi. Additionally, we dispatch more than 70 million battery units each year.
