RB 1500 or RB 2000: which battery booster is right for you?
10 November 2026
CTEK’s new compact battery boosters both provide a quick and easy way to start your vehicle when a dead battery stops you moving. But which booster – the RB 1500 or RB 2000 – is the best choice for you?
Choosing the right battery booster depends on three things: the vehicle you drive, how you expect to use the booster and how much starting power you need. Both CTEK’s compact new RB 1500 and RB 2000 are designed for lead-acid 12V batteries, combining emergency starting power with portable power for devices and a multi-mode flashlight for multiple uses.
Both models are easy to store in a vehicle, feature detachable cables and can deliver 20 starts between charges. The main difference is power: the RB 1500 provides 1,500A peak battery current, while the RB 2000 provides 2,000A.
Choose by vehicle type
Motorcycles: choose the RB 1500
For a motorcycle, the RB 1500 is the natural choice. Its 1,500A peak current provides the starting power needed for two-wheeled engines, while its compact size makes it practical to carry under a seat. The three-mode light is also useful if a breakdown happens after dark.
Regular petrol or diesel cars: Either model is ideal
Both boosters are suitable for a standard petrol or diesel car. Choose the RB 1500 if you want capable everyday backup in a small practical package. Choose the RB 2000 if you prefer the reassurance of a higher 2,000A peak current.
Powersport vehicles: match the booster to the engine
Either model can provide dependable backup for a powersport vehicle. The RB 1500 is a strong option for typical engines; choose the RB 2000 when the vehicle has a larger-than-average engine or when extra starting power is your priority.
How will you use it?
For emergency starting…
If you’re confronted with a dead battery, both models offer up to 20 starts between charges. Keep the booster charged and stored in or with your vehicle so it is ready when needed.
For power on the go…
Both boosters can charge phones and other handheld devices through USB-A and USB-C connections. The power bank can provide an everyday convenience or help in an emergency.
For reliable light, when you need it…
The three-mode flashlight provides bright illumination and can light up a campsite, a vehicle interior or anywhere else, and help make you visible to other road users during a breakdown.
Safety comes as standard
Whichever model you choose, both boosters include ten built-in safety features, including reverse-polarity protection and spark-proof technology. These safeguards are designed to make connecting and using the booster straightforward, even for a first-time user.
Which CTEK booster should you buy?
Choose the RB 1500 for a motorcycle, a typical powersport vehicle or a regular car with a standard sized engine – it provides everyday backup, anywhere.
Choose the RB 2000 for a larger-engined regular car or powersport vehicle, when higher peak current is the priority.
Order now, enjoy always
Both models combine vehicle starting, portable device charging and roadside lighting in one compact unit. Select the power level that best fits your vehicle, charge the booster and keep it close at hand for greater confidence on every journey.
