CTEK CS Free

Product detailed description

Multi-functional portable charger and smart maintainer with Adaptive Boost technology

CS FREE gives you the freedom to charge and maintain any 12V lead acid or lithium battery wherever you are – even if you’re nowhere near a power outlet. Use it as a portable charger to top up your battery with mains power, or hook it up to a solar panel kit or 12V battery for complete charging freedom anywhere you go. CS FREE also features our revolutionary Adaptive Boost technology so if your vehicle won’t start, just connect it up and CS FREE will automatically analyse the state of your battery. It’ll then work out the safest and quickest way to give it the power it needs to start your vehicle within 15 minutes. Unlike most ‘boosters’, CS FREE is sensitive and safe, so it avoids damaging your battery or your vehicle’s electronics by only giving it the charge it needs to get you going. CS FREE is also a smart maintainer and hi-tech powerbank to keep your battery and tech powered up so they’re always ready to go.

Flat battery? No problem!

Maybe you don’t use your vehicle every day, or you have a car, motorcycle or another leisure vehicle that only gets taken out every now and then – or you keep it in storage over the close season.  One day you decide to take it out but – and probably not for the first time – you find your battery’s flat. So what happens next – how do you revive a dead battery?

If your vehicle’s near a power outlet and you already own a battery charger – or you can borrow a friend’s – you should be able to connect it all up and the vehicle might be good to go in a few hours. 
But what if you’re nowhere near a power outlet and you need to get going a lot quicker?  It doesn’t matter how powerful your regular battery charger is – if you can’t plug it in anywhere, it’s no use to you. 

You could be stuck at the side of the road, in a public car park or out in the wild – but if your battery’s flat and you can’t get power, you’re not going anywhere.

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 a 12V power bank for your car or other vehicle that is completely safe for the battery and your vehicle electronics.
