CTEK, the global leader in vehicle charging solutions, has launched the CS ONE (Gen 2) battery charger, taking the groundbreaking CS ONE even further, with built-in Wi-Fi and a fully redesigned CTEK App – raising the bar for smart charging. Engineered for ultimate simplicity and performance, this next generation unit combines cutting-edge technology with intuitive design to deliver a seamless, connected charging experience like never before.
With remote access, real-time monitoring and full charge history all delivered through the app, the latest CS ONE model now gives users total control – whether they're across the garage or across the globe.
Building on the global success of the original CS ONE, the Gen 2 version evolves what was already the world’s smartest charger. It’s designed for drivers, collectors, restorers and professionals who demand more: more precision, more data, more control – with less effort.
At the core of the CS ONE is CTEK’s exclusive APTO™ Adaptive Charging technology, which automatically identifies your battery’s chemistry, size, and condition – then delivers a fully optimised charge without the need for buttons, settings or modes.
Just connect and walk away. The charger does the rest.
With full Wi-Fi and Bluetooth integration, the all-new CTEK App transforms the way you interact with your charger. More than just monitoring, the app becomes your mobile command centre for precision battery care.
App-connected features include:
From daily drivers to rare collectibles, the CS ONE ensures your battery is always ready – on your terms.
Whether you own one car or a curated garage, the CS ONE is engineered to meet the standards of enthusiasts and experts alike. It’s not just a charger – it’s a fully connected battery care solution that redefines what’s possible.
Fredrik Uhrbom, President, Consumer Division at CTEK, said:
“We’ve packed this exciting next generation CS ONE with even more technology that makes smart charging even smarter. With built-in Wi-Fi and our most advanced app yet, users can control, customise and monitor their battery charging experience like never before. It’s truly powerful simplicity in action.”
From the rugged CS ONE Bumper to the sleek CS Wall Mount, and the CTEK Adaptor Cable for total CTEK accessory compatibility, every detail has been designed for style, protection and performance.
The CTEK CS ONE (Gen 2) is available in key markets with full app functionality, live and ready. Visit weblink to explore the next generation of smart charging.
