YESPER Battery Jump Starter - Portable Car Starter for All Gas & Diesel Engines

YESPER's high-end talent team, with 10 years of experience in the automotive field, is dedicated to the R&D of the jump starter. Intelligently designed and featuring unique DSLI technology, we provide you with a safe, portable, and powerful emergency jump starter. Our objective is to deliver a product that is "high standard, high grade, high efficiency, and high brand."

Hey, car travel lovers! Don't be desperate - always say "YESPER!" What's our biggest feature? We can start a dead battery by simply pressing the BOOST button on the jumper cables. Is the battery capacity real, or is there an exaggeration? We refuse to exaggerate the battery capacity - our YESPER YJS SPEED SERIES and YESPER ARMOR SERIES offer the genuine battery capacity.

The YESPER YJS40 jump starter is packed with features that make it easy to carry and store. It boasts a DSLI IV Intelligent Control Technology, which has increased the voltage by 30% to 14.8V and the peak current of the starting current to 4120A, allowing it to start a car in just 1 second. The powerful intelligent temperature control technology also helps reduce the starting temperature, ensuring a faster, stronger, and safer start.

With a true capacity of 24000mAh (88.88Wh), the YJS40 can provide up to 60 jump-starts on a single charge, tested to start a 1.5L gas engine. It's compatible with all gas engines and diesel engines up to 10.0L, as long as the starter battery is 12V lead-acid. Even if the car battery is completely dead, you can press the BOOST button, and the jump starter will force the car to restart.

The YJS40 offers versatile charging options, including USB (5V/2.4A), USB QC (5/9/12V), and Type-C (5V/3A) input/output ports, as well as a DC (15V/10A) port to power various DC devices, such as tire inflators, car vacuum cleaners, and car refrigerators.

The built-in LED work light has three modes: Flash Light, Strobe Light, and SOS Light, making it a multi-purpose flashlight for camping, outdoor, indoor, and travel use, providing illumination in dark or emergency situations.

The YJS40 is made of fire-proof ABS material, ensuring it is more sturdy and durable for adventurous life, with multi-function (rain, dust, and drop resistance) features.

What you get in the package: YESPER YJS40 Car Battery Jump Starter, Heavy-Duty Jumper Clamps, USB to Type-C Cable, Cigarette Lighter Adapter, Carrying Case, and User Manual, all backed by an 18-month worry-free warranty and lifetime technical support.
