YESPER has dedicated itself to the research and development of jump starters, empowered by both advanced technology and innovation. Committed to making more car enthusiasts benefit from us, the brand's pursuit is to provide safe and practical products, as well as efficient and high-quality service.

How to start a car with a completely dead battery? First, select the correct button (12V/24V) on the jump starter based on your car battery voltage. The display will show "12VJUMP START READY" for 12V and "24VJUMP START READY" for 24V. If the display shows something else or nothing at all, disconnect the positive car battery cable, clamp the positive and negative ends of the car cable, and long-press the "12V" or "24V" button for 3 seconds. The correct information will then appear on the display. Reconnect the car battery and try starting the car again. Make sure the selected button matches the car voltage.

YESPER's most powerful heavy-duty 12 and 24 Volt Jump Starter boasts 6000 Amps peak cranking amps, capable of starting all Gas / Diesel engines. It can automatically identify 12V and 24V cars and switch the starting voltage, allowing you to start a 100% dead car without relying on anyone. Refuse to use bulky lead-acid batteries, YESPER utilizes lighter, safer and better-performing lithium-ion batteries. Weighing only 4.1 lbs, this compact and portable jump starter packs a punch.

Featuring DSLI IV Intelligent Safe Tech, the YESPER portable battery jumper boosts the voltage by 30%, delivering a more steady cranking current up to 6000A to fast-start your car in 1 second.
