Ctek CS FREE battery charger (12V, 20 A) 40-462

Multifunctional portable charger and intelligent maintenance device with Adaptive Boost technology

CS FREE means freedom. The freedom to charge 12 V lead-acid and lithium-ion batteries anywhere. Even without mains power. As a portable charger, it recharges batteries with mains power - or with the power supplied by solar panel kits or secondary batteries. The CS FREE's revolutionary Adaptive Boost technology automatically analyzes the condition of the battery when the vehicle fails to start after simply plugging it in. It then determines the safest and quickest way to supply the battery with the energy required for a successful vehicle start within 15 minutes. In contrast to most so-called boosters, the CS FREE takes a differentiated and safe approach. The battery and the vehicle's electronics are therefore not damaged by indiscriminate charging. The CS FREE is also an intelligent maintenance device and a high-tech power bank that keeps the battery and electronics ready for use at all times.
