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. You can use the CS FREE in multiple ways; use it as a portable charger to power up your battery, connect it to a power outlet or you can even hook it up to a solar panel kit! 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. It can charge and maintain any type of 12V-lead-acid and lithium (LiFePO4) batteries and there is an extensive range of accessories which gives users freedom from a power outlet. 

CTEK CS FREE given Auto Zeitung recommendation

Leading German motoring magazine Auto Zeitung has selected CTEK’s CS FREE as a ‘must have’ accessory for the camping world! 

In Auto Zeitung’s recent review of camping accessories, the CS FREE - the world’s first multi-functional portable battery charger and smart maintainer with adaptive boost technology - came ’highly recommended’.

Here’s what the review had to say. ”This portable battery charger should always be on board with campers. Thanks to an integrated Lithium Ion power pack, the CS FREE can not only support a discharged car battery when starting, but can also be used without a mains connection if you find yourself far away from civilization. In addition to lead acid batteries, the CS FREE can also charge the lithium batteries (LiFePo4) on modern mobile homes via a 230 Volt mains connection, for full or trickle charging.”

Auto Zeitung also mentions other features of the CS FREE including the option to charge smartphones, cameras and laptops from the USB ports, the countdown function that informs you of the remaining charge time, the maintenance charging function and the option to charge deeply discharged batteries from the mains.

The CS FREE is certainly the one accessory that campers, caravanners and motorhome owners simply shouldn’t be without! 

You can use the optional, easily transportable folding solar panel charge kit to charge the CS FREE while you’re off grid. The CS FREE also has USB-A and USB-B ports to charge your mobile phone, PC, tablet and other devices.

Holidaying in the great outdoors is fun and exhilarating, but when you’re out in the middle of nowhere and away from a power source, the last thing you want is to be stuck with a flat battery. It uses revolutionary ’adaptive boost technology’ to gently and safely give a flat battery enough charge to get you going in around 15 minutes. This is completely safe for the vehicle’s electronics, unlike most boosters or jump starters that deliver a sharp burst of power to bring the battery into life. 

So you see, with the CS FREE, you needn’t worry, this innovative portable battery charger will get you safely charged and back on the road to continue your adventures - wherever you are, and wherever you want to go. You can charge the CS FREE from mains electricity before you leave home, and it will keep its charge for up to a year!

And with the optional accessories, such as the solar panel and USBC charge cable 12V accessory plug, coupled with the ability to charge from mains power too, it really has everything you need to keep you moving, and keep you connected - all in one handy package!
