CTEK CS FREE is a multifunctional device that combines the functionalities of a battery charger, maintainer, and adaptive booster. Unlike traditional jump starters, the CS FREE utilizes adaptive boost technology to safely revive a depleted car battery without harming the battery or vehicle's electronics. It can also function as a charger and maintainer for 12V lead-acid or lithium batteries, ensuring optimal battery health. The CS FREE offers versatility by providing charging options through a mains power source, solar panels, or a separate leisure battery. Additionally, it functions as a high-tech power bank, allowing users to charge USB devices for uninterrupted mobile connectivity.
