Whether it’s the school run, a work trip, or a weekend getaway, a dead battery can stop everything. RB 3000 and RB 4000 is your instant starting solution for dead 12V batteries, combining smart safety, everyday versatility, and robust Swedish design.

We all need a boost from time to time when we feel flat, and so do vehicle batteries. Today, CTEK are introducing two new boosters with instant starting power for dead 12V batteries.

The RB3000 provides up to 30 jump starts on a single 2.5 hour charge, the RB4000 up to 45 after charging up for just 3.5 hours. Both are compact and lightweight enough to take everywhere and super easy to use.

And they do more than just boost. With USB-A and USB-C ports, they double up as high-capacity power banks for your electronic devices. Plus, a built-in LED flashlight with emergency modes keeps you prepared and safe. And each comes with a protective case that prevents accidental activation and protects the unit when you’re on the go.

Don’t fall flat

Life doesn’t wait – and neither should you. Whether it’s a school run, work trip or weekend getaway, a dead battery can derail any plan. With modern vehicles placing increasing demands on their batteries, a flat battery can bring everything to a halt.

Designed to deliver instant starting power for dead 12V vehicle batteries, both the RB 3000 and RB 4000 offer powerful performance, smart safety and everyday versatility in a single compact device.
