Booster, jumper cables, power bank… they all have cables and wires right? Are you tired of having a mess in your car with all of these devices and cables that tangle? This won’t be a problem anymore with the CTEK CS FREE. The CS FREE is four products in one unit which makes your life easier and tangle free. You don’t need multiple devices that take up valuable truck space and leave you with many messy cables – the CS FREE is compact and makes for a more organized trunk! 

This will not only make your life easier; it will also be cost effective too! Instead of buying four separate products, you only have to buy one, that actually costs less than buying individual products, and does everything your car battery will ever need. Use the CS FREE for simpler, easier and cost-effective motoring.  

Because you see the CS FREE is a portable charger for topping up your vehicle battery, a smart maintainer, a hi-tech power bank and an adaptive booster. You can use it to charge your 12V battery, charge your phone or laptop and use it to boost your vehicle battery when it has run out of power. Wherever you are, off grid or in the city, the CS FREE will always be of help. 

Imagine that you are stranded on the road far away from the nearest power outlet with a dead battery. But if you have the CS FREE with you, its unique Adaptive Boost function means you will be able to safe-start your vehicle in only 15 minutes, without risk of damaging vehicle electronics. 

This is especially important during the winter season when your battery is getting affected by the cold weather. Your battery needs to do a lot more work and your alternator might only charge up your battery to around 60%. That’s why it’s crucial to always have a portable charger with you. 

The German outlet Autobild is testing new products every year, bicycle racks, child seats and chargers is just a few of the 28 products they have tested this year. The twelve editors have picked their favorite and the editor in chief Max Bitter, has chosen the CTEK CS FREE.  

Autobild is one of the biggest automotive outlets in Germany and this were their motivation about the CS FREE, “No power outlet nearby and the battery doesn't really want it? Then there is now the solution. With the portable charger CS FREE from CTEK, the battery can not only be charged, but also serviced at any time. Once the battery is charged, it lasts up to a year, optionally the battery can even be charged with a separately available solar panel.”  

The CS FREE is four cutting edge products in one portable unit – Adaptive Booster, smart maintainer, battery charger and hi-tech power bank. The Adaptive Boost makes sure that your dead battery will be able to start in a safe and gentle way in around 15 minutes.

Furthermore, you can also connect it to a 12V battery for complete charging freedom anywhere you go. When used as a Smart Maintainer, your battery can remain in ideal condition no matter where you go. When used as a hi-tech power bank, you are able to top up the battery of your smartphone, your laptop or camera anywhere you go. 

The CS FREE is an easy and user-friendly product – no extra modes or buttons, just a bright display with countdown LEDs that shows the time left before the battery is fully charged.

CTEK’s CS FREE portable battery charger and maintainer has been named an essential car accessory by Claudio Anniciello, owner of Italian automotive website test-driver.it.

Test Driver is an automotive information portal for those looking for an objective and conscious opinion on the world of cars, and in a 12 minute video on the Test Driver YouTube channel, Mr Anniciello unboxes, demonstrates and test the CS FREE. 

Here’s what Mr Anniciello has to say about this groundbreaking portable battery charger from CTEK. 

“The new CTEK CS FREE is a car accessory that is essential, especially if you don't use your car often. For the first time in the world, a power bank for the car battery with an internal lithium battery that helps to provide charge to the 12 V car battery, allowing you to start the engine if the battery is deeply discharged or to bring it to the right level. It is important to know that it does not need to stay connected to the grid. You charge it at home, connect the clamps to the car battery and let it do its job.  

“CTEK CS FREE also works as a traditional charge maintainer and, in this case too, it doesn’t need to be connected to the grid.”  

Flexibility is one of the great things about the CS FREE. You can use it as a portable charger to top up your battery, as a more traditional type of charger by connecting to mains power, or hook up to a solar panel kit or 12V battery for complete charging freedom. In fact, maintenance charging your battery will actually extend the lifespan of your battery by up to three times! 

Mr Anniciello continued “It is ideal for motorbikes, cars, campers and so on. It is unconceivable that, up to now, there wasn't any accessory dedicated to those who haven't got the possibility to maintain their battery because they don't have a garage.” 

Named 2021 Product of the Year by Auto Express, CTEK’s CS FREE is the world’s first multi-functional portable battery charger and smart maintainer, with adaptive boost technology – compatible with all types of 12V lead-acid battery as well as lithium (12V LiFePO4) batteries too. Simply charge the CS FREE from mains electricity before you leave home, and it will hold its charge for up to a year! Then, if you do find yourself stranded with a flat battery, the CS FREE will gently and safely give you enough charge to get you going in around 15 minutes. This is completely safe for the vehicle’s electronics, unlike most traditional boosters or jump starters, that deliver a sharp burst of power to effectively shock the battery into life.   

The CS FREE has USB-A and USB-C ports to charge your mobile phone, PC, tablet, camera and other devices, and there’s an optional, easily transportable folding solar panel to power up the CS FREE while you’re off grid.
