CS Free delivers portable battery charging in just 15mins, with no power source.
CTEK’s new CS FREE portable battery charger can recharge a flat battery in just 15 minutes, even when nowhere near a power outlet. A “must-have” for boaties (especially those with only a single battery onboard) and vehicle owners, CS FREE, use a plug-in detachable DC clamp cable to quickly and easily connect to the battery connection points.
CTEK’s innovative Adaptive Boost technology then automatically works out the quickest and safest way to power up and protect the battery so that, in just 15 minutes, it will have enough power to restart the engine.
Unlike most’ boosters’, CS FREE is sensitive to the state of the battery and supplies just enough charge to get the boat or vehicle going, avoiding damage to the battery and the electronics. With an internal battery that, when fully charged, will remain charged and ready to use for up to a year, CS FREE can be charged up and powered using solar power or a 12v battery and used for maintenance charging.
Featuring a LED display that shows how much time is left until the battery is fully charged, CS FREE works with all types of 12V lead-acid and lithium batteries. It has USB-C and USB-A outlets to charge laptops, smartphones and tablets, has a new ergonomic design and tough, durable case and comes with a two-year “peace of mind” warranty.
