YESPER Car Battery Jump Starter 6000A

A dead battery is a bigger problem when you’re away from help or driving a vehicle that needs more than a basic 12V booster. The YESPER jump starter is designed for both 12V and 24V gas and diesel engines, with a 36400mAh battery and a 6000A peak rating. It also works as a portable power source, so it can charge two devices and provide light when you’re dealing with a roadside delay. One detail matters in an emergency: a completely dead battery requires you to select 12V or 24V manually rather than relying on automatic switching.

Best use cases

This jump box is aimed at drivers who want one unit for different vehicle voltages, including trucks, and would rather carry a rechargeable battery pack than depend on another driver or a bulky lead-acid booster. For example, if a vehicle won’t start in a parking lot, you can connect the included jumper cable, choose the correct voltage if the battery is completely dead, and use the pack to attempt a start. Its dual USB ports can also charge two devices at once, while the light offers Lighting, Strobe, and SOS modes.

The maker says the unit can provide up to 65 jump starts per charge and uses preheating technology for cold-weather starting, with operation described down to -40. Those claims make it relevant for cold-weather or infrequent-use situations, but actual results can depend on the vehicle and battery condition. Worth considering if you need 12V/24V flexibility and backup charging in the same device. It’s not for you if you want a small, single-purpose booster and don’t need the extra capacity or features.

Product specs

• Type: 12V/24V car battery jump starter
• Peak current: 6000A
• Battery capacity: 36400mAh
• Weight: 5.7 lbs
• Charging: Included 145W, 29V AC adapter, the maker states a full charge takes one hour
• Included: 27.5-inch jumper cable, USB-A to USB-C cable, AC adapter, and user manual

The unit can identify a vehicle’s voltage and switch automatically in normal use, according to the maker. For a completely dead car battery, the instructions in the product description call for manual voltage selection. That’s a small but important distinction: under pressure, the correct setting still depends on knowing whether the vehicle is 12V or 24V. The description also says five minutes of charging can be enough to start a car, but that should be treated as an emergency-use claim, not a substitute for keeping the pack charged.

Where it shines

The appeal is the combination of jump-starting, device charging, and a three-mode light in one carryable unit. A basic 12V-only booster may be the simpler fit for a driver who just wants occasional car starting, this model’s case is stronger when 24V support and the larger battery pack are useful. At 5.7 lbs, it is portable, though it is still something you’ll need to make room for in the vehicle rather than a tiny pocket accessory.

The included AC adapter gives you a defined way to recharge at home, and the USB ports add a practical fallback for a phone or another device during a delay. The trade-off is that the product description does not specify vehicle-by-vehicle fit or explain how performance varies with battery condition, so the peak-current figure alone can’t settle every compatibility question. Check your vehicle’s voltage and the unit’s instructions before relying on it for a particular emergency.

Is it worth it?

This YESPER jump starter makes the most sense for someone who wants a single pack for 12V and 24V vehicles, plus USB charging and an emergency light. The automatic voltage feature is convenient, but the manual selection required for a completely dead battery is a real step to remember. If you only drive a 12V car and want the simplest possible booster, a more basic unit may be easier to justify, if the broader vehicle support and extra functions match your needs, this pack has a clearer purpose.
