Our next-generation lineup – smarter, stronger and more connected than ever

We announced a bold expansion of CTEK’s product portfolio at the SEMA Show in Las Vegas. With the debut of the NXT Series Chargers, the CS ONE (Gen 2) smart charger, and the RB 3000 and RB 4000 Premium Boosters, CTEK is redefining how drivers charge, maintain and power their vehicles. 

Fredrik Uhrbom, President of CTEK’s Consumer Division, describes it as an exciting new chapter for CTEK: “From our advanced NXT chargers to the next-generation CS ONE and our powerful new RB Boosters, we’re giving customers more control, capability and confidence than ever before – whether they’re at home, in the garage or on the go.” 

NXT Series – next-level power for every driver 

The new NXT 5 and NXT 15 chargers represent the next evolution in professional-grade battery charging – built tough, designed smart and powered by CTEK’s patented technology: 

NXT 5: Compact 5A charger ideal for motorcycles, cars and seasonal vehicles. 

NXT 15: 15A high-performance charger for trucks, boats and off-road vehicles. 

Both models deliver automatic, spark-free operation and feature heavy-duty, temperature-compensated performance for ultimate reliability in any condition. 

CS ONE (Gen 2) – the future of smart charging 

Unveiled for the first time at SEMA 2025, the CS ONE (Gen 2) introduces built-in Wi-Fi and Bluetooth connectivity and a redesigned CTEK App, giving users complete remote control over charging and monitoring. 

Key innovations include: 

• APTO™ Adaptive Charging Technology that automatically detects and optimises charging for any 12V battery. 
• Polarity-free clamps for safe, simple use. 
• Connect & Forget functionality for long-term battery maintenance. 

Fredrik said: “The CS ONE (Gen 2) delivers the most advanced charging experience we’ve ever created – effortless, intelligent and entirely connected.”  

RB Series Boosters – instant power, anywhere 

Also debuting at SEMA, CTEK introduced the RB 3000 and RB 4000 Premium Boosters, combining instant jump-start capability with advanced safety and portable power-bank functionality: 

RB 4000: 4000A peak current, up to 45 starts per charge – ideal for large vehicles and harsh conditions. 

RB 3000: 3000A peak current, up to 30 starts per charge – perfect for everyday use. 

Both booster models include USB-A/USB-C ports, multi-mode LED lights and spark-proof technology, all within a rugged, compact Swedish design. 

The NXT 5, NXT 15 and RB Series Boosters are available to order through authorised CTEK distributors and at www.ctek.com and the CS ONE (Gen 2) will be available in early 2026.
