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.
