CS FREE

CTEK’s CS FREE is the world’s first multi-functional portable battery charger and smart maintainer with Adaptive Boost technology. You can charge and maintain any 12V lead acid or lithium battery anywhere using mains, solar or leisure battery power. And if your battery’s flat, CS FREE’s revolutionary Adaptive Boost technology will work out the safest and quickest way to power up your battery to get you going within 15 minutes.

Multi-functional 4-in-1 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.
