CTEK’s powerful new RB 3000 and RB 4000 portable boosters are designed to quickly and easily jump start boats and vehicles with dead 12V batteries.  

Featuring CTEK’s renowned quality and reliability, the new RB boosters mean boaties and car and RV owners will always be able to get underway, regardless of whether their batteries are flat or not.

Powerful, compact and always ready to go, the versatile RB boosters are also packed full of safety features including spark-proof technology and reverse polarity protection. They also feature additional USB charging ports and a built-in LED flashlight with three lighting modes. 

Delivering instant power, the robust Swedish-inspired boosters can be used multiple times. The RB 3000 has the power to restart an engine up to 30 times, while the RB 4000 can do up to 45 restarts before needing a recharge. Both models are capable of jump starting a wide range of 12V lead-acid batteries, including AGM, EFB, WET, GEL and Ca/Ca. 

Phones, tablets and other electronics can also be quickly recharged through the RB boosters’ built-in USB-A and USB-C ports.

The ergonomic designed RB 3000 and the RB 4000, which are simply recharged using the USB-C port, are incredibly easy to use and come complete with clamps, storage bag, user guide and 2-year warranty.  

Featuring CTEK’s renowned quality and reliability, the new CTEK RB 3000 and RB 4000 portable boosters are now available through Lusty and Blundell’s nationwide network of leading marine dealers and at their three showrooms in Albany, Whangarei and Tauranga.
