The YESPER YJS SPEED SERIES and YESPER ARMOR SERIES offer a comprehensive range of accessories that are easy to carry and store. Our flagship product, the YESPER YJS40, is the focus of this discussion.

The YESPER YJS40 is equipped with DSLI IV Intelligent Control Technology, which has significantly improved 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. This powerful, intelligent temperature control technology reduces the starting temperature, enabling faster, stronger, and safer jumps.

Contrary to exaggerated claims, we pride ourselves on providing accurate battery capacity information. The YESPER YJS40 jump starter has a true capacity of 24000mAh (88.88Wh), which can deliver up to 60 jump-starts on a single charge, even for vehicles with gas engines up to 1.5L or diesel engines up to 10.0L, as long as the starter battery is 12V lead-acid.

The YESPER YJS40 offers versatile charging options, with 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.

Additionally, the YESPER YJS40 features a multi-purpose LED flashlight with three modes: Flash Light, Strobe Light, and SOS Light, making it useful for camping, outdoor activities, and emergencies.

Designed with adventurous lifestyles in mind, the new YESPER YJS series jump starters are made of fire-proof ABS material, ensuring sturdiness and durability, as well as providing multi-function rain, dust, and drop resistance.

The YESPER YJS40 package includes the 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.
