CTEK's CS FREE is the world's first multi-functional portable battery charger and smart maintainer with Adaptive Boost technology. Featuring a versatile design, the CS FREE allows you to charge and maintain any 12V lead acid or lithium battery anywhere, using a power outlet, solar power, or a leisure battery. Its revolutionary Adaptive Boost technology ensures the safest and quickest way to power up a dead battery, getting you back on the road within 15 minutes.

As a portable charger, the CS FREE can be plugged into a power outlet to top off your battery, or connected to a solar panel kit or 12V battery for complete charging freedom. The Adaptive Boost technology is a standout feature, automatically analyzing the state of your battery and providing the exact charge it needs to start your vehicle, without risking damage to the battery or vehicle electronics.

In addition to its charging capabilities, the CS FREE also serves as a smart maintainer, keeping your battery in peak condition whether at home or off-grid. It further functions as a high-tech power bank, allowing you to charge laptops, smartphones, tablets, and cameras using the USB-A and USB-C ports.

Registered in the U.S. Patent and Trademark Office, the CS FREE is a versatile and innovative product that combines four cutting-edge features into a single portable unit: an Adaptive Booster, a battery charger, a smart maintainer, and a high-tech power bank. This comprehensive solution eliminates the need for separate jumper starters, chargers, and power banks, providing users with a convenient and reliable way to keep their vehicles and devices powered up and ready to go.
