With CS FREE, users are no longer restricted by power outlets, achieving truly portable charging. Even if power is not available, 12V lead-acid and lithium batteries can be charged and maintained. For long-term maintenance charging, it can be charged from the mains using the included PD adapter, or using a solar panel kit or a separate service battery. And, with USB-C and USB-A output interfaces, it can charge laptops, smartphones, tablets, vehicles, etc.

The CS FREE comes with an internal battery that can be fully charged in less than an hour via the unit’s fast USB-C input. And, once fully charged, it can hold its charge for up to a year, making it ideal to keep in the car for when needed. “The CS FREE is the first in a new generation of CTEK battery chargers,” said Stefan Magnusson, CTEK Aftermarket Sales Director. “Consumers want to be free from the power cord and be able to get their batteries started quickly.”

The CS FREE is suitable for cars, motorcycles, RVs, vans and boats, and is easy to use. There is no need to select a cumbersome mode, just connect and the CS FREE will do the rest. When charging a low-power battery, the user can see the battery power through the LED display to determine when to start the car. In addition, the countdown display can show the time when the battery is fully charged.

With the help of a simple and clear LED display, it can be seen whether the battery power is sufficient to start the car. Moreover, CS Free is sensitive to the state of the battery and only releases the right amount of charge for the vehicle to start. It is completely safe for the on-board electronic equipment.
