CTEK RB 4000 12V Jump Starter, 4000A Peak | 40-624

The CTEK RB 4000 combines a portable 12V battery booster, USB power bank and LED flashlight in one compact unit. Its 4,000A peak-current rating provides starting assistance for compatible vehicles with discharged lead-acid batteries, while USB-A and USB-C ports keep compatible electronics powered on the go. Ships fast across Canada and the US.

Check battery compatibility: Designed for compatible 12V lead-acid vehicle batteries, including WET, MF, Ca/Ca, AGM, EFB and GEL types. The internal lithium-ion battery powers the booster; it does not mean the unit is specified for jump-starting lithium vehicle batteries. Follow CTEK's instructions and the vehicle manufacturer's jump-start procedure. The 4,000A figure is a peak rating, not continuous starting current.

Starting Power

  • Battery peak current: 4,000A.
  • Maximum cranking current: 2,060A.
  • Start current: up to 1,300A.
  • CTEK rates the RB 4000 for up to 45 starts per charge; actual results depend on the vehicle, battery condition, temperature and booster charge level.
  • Spark-proof technology and reverse-polarity protection support correct operation, but do not replace following the instructions.

Power Bank and LED Flashlight

Use the USB-A QC3.0 and USB-C PD30W outputs to power compatible phones, tablets and other electronics. The integrated LED flashlight offers standard, strobe and SOS modes for visibility and signalling when needed.
