4-in-1

CS FREE is the world’s first multi-functional, 4-in-1 portable charger. Let’s take a look at the different ways we can use it.

Flat battery?

You are out in the car, boat or motorcycle and you get a flat battery – - so what happens next? And what if you’re nowhere near a power outlet? 

You could be stuck at the side of the road, in a public car park or out in the wild – and if your battery’s flat and you can’t get power, you’re not going anywhere. There is no need to worry - the CTEK CS FREE has Adaptive Boost, that can quickly get you going from a flat battery!

What is Adaptive Boost?

The CS FREE is an Adaptive Booster that will get you going from a flat battery within 15 minutes. It automatically analyses the state of the battery and works out the safest way of giving it enough power to start the vehicle. Unlike most boosters or jump starters, the CS FREE is sensitive to the state of the battery and only gives it the charge it needs to get you started – so it’s completely safe for your battery and your vehicle electronics.

Off-Grid? No problem!

The CS FREE is compatible with a great range of accessories available for off-grid charging and maintenance, for complete freedom from mains power.

SOLAR PANEL CHARGE KIT The CTEK Solar Panel pairs perfectly with the CS FREE, so you can charge your battery via a solar panel and use it wherever you are. Fold it, transport it, and connect it in seconds, this intelligent and responsive solar panel kit delivers reliable solar power whenever you need it.

USB-C CHARGE CABLE CLAMPS Attach the USB-C charge clamps to a separate 12V service battery, for battery charging and maintenance, without needing to connect to a power outlet.

USB-C CHARGE CABLE (12V PLUG) Plug the USBC-C charge cable into your vehicle’s 12V accessory socket and recharge your CS FREE whilst on the move!

Healthy batteries, happy times

The CS FREE is also an intelligent charger and maintainer that will keep your batteries in optimum condition, delivering maximum performance. 

CS FREE can keep your battery topped up for longer periods of time. In fact, maintenance charging the battery via traditional mains power, solar panel kit or 12V service battery over the idle seasons will extend the lifespan of your battery by up to three times.

Neat and tidy storage

We have two great ways to store the CS FREE, to make it even easier to use.

CS STORAGE CASE Made from tough and durable 600D water-resistant nylon, with a padded interior, the CS STORAGE CASE bag provides practical storage and protection for your CS FREE.

CS WALL MOUNT Featuring CTEK’s unique mounting system, the CS Wall Mount provides practical storage for your CS Charger, neat cable management as well as quick and easy access whenever you need it.
