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.
