Extreme Compactness Leading Industry Innovation: With equivalent technical parameters, the JP400 jump starter achieves the integration of multi-functions within the smallest unit. it not only takes into account the usage scenarios but also maximizes the performance of each function. 2500peak power easily jump start 12V vehicles up to 8.5LGas/6.5L Diesel engines in seconds even in extreme temperature(-4°F~140°F). This car starter also has BOOST function, automatically detects the battery voltage and helps you start fully-drained batteries.

Cordless Smart Emergency Air Pump: Jump starter with air compressor provides 150 PSI air flow quickly inflates car tires in a few minutes. This tire inflator and battery jumper is designed with preset & auto-off shut-off, easy to use. Just select 4 inflation modes ( cars, motorcycles, bicycles, balls ) in the screen and set the pressure. it will automatically stop inflating when reaches the preset value.

Born for Safety: Designed with an integrated battery management system and smart self-identifying clip, this battery jump starter is safe and fully insulated. 10 protection types, including Spark-Proof Protection, Reverse-Charge Protection, Over-Charge Protection, Over-Current Protection, Short-Circuit Protection, Reverse-Polarity Protection, Low-Temp Protection, High-Temp Protection, Over-Voltage Protection, Over-Load Protection, securely connects to any 12V vehicles.

Innovative CONNECTMAX Technology: Prolonged vehicle operation/parking leads to the accumulation of contaminants (oxidation/rust/oil/dust/weathering) on the car battery terminals, resulting in poor contact starting problems. New users may experience poor connection between the clamp and the battery. Our exclusive CONNECTMAX technology automatically detects impedance between the clamp and the battery. Enhanced starting performance by 30%, reliable starts every time.

Emergency Light & Power Supply: In addition to the battery jumper starter portable air compressor, it also can be serve as power supply and LED light. Dual USB port charging for phone, laptop, camera, watch and other mobile devices. 300 lumen LED light support 3 lighting modes: flashlight, strobe and SOS. light time lasting 12hours. Perfect for night road emergencies outdoor adventures.

Smart Digital LED Display: This portable car jump starter has a 4.15 inch smart LED screen, you can observe the car's voltage when jumping, choose inflation type and detect tire pressure in real time. Moreover, this powerful jump box with air compressor using 80C high rate battery and BMS self-identification lock function, self-power consumption is only 0.35mAh, which effectively reduce power loss when not in use. Standby time up to 36 months.

Upgraded Thermal Design: JP400 jump start battery pack is made of high density materials. Even if it is exposed to extreme temperatures, it has very good anti-aging, non-flammable, and non-breakable properties. The double balance beam at the bottom can maximum achieve noise reduction and shock absorption when inflating. The ventilation windows on both sides are designed to form a circulating wind, which improves the heat dissipation effect by 50% and increases the service life by 25%.
