In practice, the CLJ1200 handled a mid-size SUV and a V6 sedan with ease, even after sitting unused for three months—its low self-discharge rate ensures it’s ready when needed. The ultrabright LED is surprisingly effective for illuminating engine bays at night, and the dual USB ports (Type-A and Type-C) charge smartphones quickly, turning it into a capable emergency power bank. However, it lacks an AC inverter or air compressor, so it won’t replace a full-featured power station. The unit is also best suited for occasional use—frequent jump-starts will drain it faster than heavier-duty models.
Compared to the CJ1000DXT, the CLJ1200 is far more portable and budget-friendly, but it doesn’t offer multi-tool functionality. Against the CJ3000, it’s no match in raw power, but that’s not its purpose. It’s designed for commuters, road trippers, and urban drivers who want a reliable, no-fuss jump starter that fits in a trunk or backpack. It delivers essential performance and smart safety features in a sleek package, making it the best value-driven, everyday choice in the CAT lineup.
Choosing the Right Caterpillar Jump Starter
Peak Amperage: Starting Power
The most crucial factor when selecting a Caterpillar jump starter is its peak amperage. This determines which vehicles your jump starter can handle. Consider the engine size of the vehicles you anticipate needing to jump-start. Smaller cars (4-cylinder) generally require around 200-300 amps, while larger vehicles like V8 trucks or SUVs often need 800-1000 amps or more. A higher amperage provides more starting power, offering flexibility for various vehicle types. However, don’t overbuy – a significantly higher amperage than you need won’t necessarily improve performance and will likely increase the price. Look for models that meet at least the recommended amperage for your typical vehicle.
Battery Type & Durability
Caterpillar jump starters utilize different battery technologies, most commonly lead-acid or lithium-ion. Lithium-ion batteries are lighter, hold a charge longer, and generally have a longer lifespan compared to lead-acid. They are also less affected by temperature extremes. However, they tend to be more expensive. Consider the environment where you’ll be using the jump starter. If you work in very cold or hot conditions frequently, an AGM (Absorbed Glass Mat) battery (often found in professional-grade models) offers superior performance in extreme temperatures. The housing material is also important; rugged, impact-resistant housings ensure the unit can withstand rough handling and potential drops.
Additional Features & Functionality
Beyond jump-starting, many Caterpillar models offer a range of useful features. A built-in power inverter (like the 200-watt options) allows you to power small devices, while USB ports (Type-A and Type-C) are handy for charging phones, tablets, and other electronics. An integrated air compressor (rated in PSI) can inflate tires or other inflatables. A bright LED work light is invaluable for nighttime emergencies. Think about which of these features you’ll realistically use to justify the added cost.
Safety Features
Safety should be a top priority. Look for features like reverse polarity protection, which prevents damage to your vehicle’s electrical system if the cables are connected incorrectly. An audible alarm is a good indicator of a wrong connection. Industrial-grade, spark-proof clamps are also essential for safe operation. A built-in power switch provides an extra layer of security by preventing accidental discharge.
