Jumpstart from Zero voltage: Real peak current enables a car to be jump started in a second when the car battery is low Charge Once for 60 Times of Jumpstart: 20000mAh lithium polymer batteries feature higher capacity. Tests indicate that the fully charged jump starter can jumpstart for Toyota Crown Royal 3.0 with a naturally aspirated engine more than 50 times For Gasoline/Diesel Vehicles with Any Displacement: 4 strings of high discharge rate cells offer powerful performance for all car models and displacement. They can withstand instantly powerful current shock of a car to protect the car battery, and ensure longer service life Support 12V/8.0L gasoline vehicles and 12V/4.0L diesel vehicles Jumpstart as Usual at -20℃: A smart temperature protection chip is low temperature resistant for jumpstarting in winter easily. A built-in temperature protection resistor ensures normal operation in the environment with large temperature difference Low Consumption, 2 Years of Battery life: Low-power sleep mode with 0.05mA of static current enables the jumpstarter to stay on standby for 2 years after fully charged. It works even if you forget to charge it for a long time Clear Display Precise Battery Level: It can show the remaining battery level precisely Dual USB Output, One-Stop Power Station: The two USB ports are compatible with tablets, laptops, phones and for Switch, and support simultaneous charging of two devices Flashlight and Emergency Light: It has three types of light mode. Long press to turn on high brightness light mode and enable SOS mode when a flat tire or an emergency occurs late at night to prevent secondary accidents Intelligent Ignition Clamps: Intelligent ignition clamps with eight safety protection come with the product, which are up to the testing standards for more secure use Nine Safety Protections Above Industrial Standards: This product has nine protection designs that passed many international safety certifications to provide a strong guarantee for your safe travel Safety on Board the Aircraft Can Be Used As a Mobile Power Supply: The polymer lithium battery meets the safe standard of phone batteries. 44.4Wh of rated power conforms to civil aviation standards Specifications: Brand: Baseus Model: CRJS04 Capacity: 20000mAh/3.7V/74Wh Rated output capacity: 13000mAh Input: 5V/2A, 9V/2A(Max) Output 1: 5V/3A,9V/3A,12V/2.5A(Max) Output 2: 5V/2.4A(Max) Total output: 42W(Max) Starting voltage: 12V Starting current: 1000A Crest Value Current: 2000A Suitable for: 12V up to 8.0L gasoline engines and up to 4.0L diesel engines Size: 87*165*38mm Weight: 772.4g
