CTEK RB 4000 Battery Booster Jump Starter & Power Bank (4000A Peak)

€378,95

The CTEK RB 4000 is the most powerful booster in CTEK's brand-new RB lineup, built for workshops, fleets, recovery work and riders whose garage holds a lot more than motorcycles. With 4000 amps of peak current it starts gas engines up to 10L and diesels up to 8L, and a single charge is good for up to 45 starts.

That means one booster on the shop shelf can cover the bike, the diesel pickup, the boat and the RV. It also doubles as a high-capacity 24,000 mAh power bank with USB-A and USB-C ports, and the built-in LED flashlight has three lighting modes for working after dark.

Spark-proof technology and reverse polarity protection make it safe to use, and it's sealed to IP65 against dust and water.
