【4000A Powerful Jump Starter】 Equipped with a robust 4000A peak current and a 15,000mAh battery capacity, this device can jump-start dead 12V vehicles (up to 8.0L gas or 7.0L diesel engines, including hybrids) in just 3 seconds. It delivers reliable starting performance even in extreme temperatures (-20°F to 70°F) with as little as 80% battery life. Enjoy peace of mind with up to 50 jump starts on a full charge and a durable lifespan of over 1,000 charge cycles.

【Built-In Smart Air Compressor】 Features a maximum pressure of 160 PSI and an 8L/Min airflow. It takes about 8 minutes to fully inflate a 205/55 R17 car tire, or just 3 minutes to refill a 305/65 R18 tire (Testing based on a flat standard 185/65 R15 tire). The smart preset function automatically shuts off when the target pressure is reached, eliminating the need for constant monitoring. Ideal for cars, bicycles, motorcycles, basketballs, and pool toys. (Note: Does not support heavy-duty truck tires).

【4-in-1 Versatile Multi-Tool】 Much more than a car battery booster and tire inflator, this device also functions as a high-capacity portable power bank and an emergency LED flashlight. It supports USB fast charging to quickly power up your smartphones, tablets, and other devices (Input: 5V/1A, Output: 12V/2A). The integrated 300-lumen LED light offers 4 modes: Constant Lighting, Strobe, SOS, and Warning, keeping you safe in the dark.

【LCD Display & User-Friendly Design】 The cordless inflator features a clear LCD screen for real-time data monitoring and three optional pressure unit formats for your convenience. Powered by a unique turbocharged system, it provides rapid inflation lasting up to 6 minutes. It also includes a detachable, extended air hose to make roadside inflation easier and more flexible.

【What You Get & Warranty】 Package includes: 1 x Smart Jump Starter & Air Pump, 1 x Air Tube (23.6in/60cm), 1 x Inflating Needle, 1 x Inflatable Nozzle, 1 x Presta Valve Adapter, 1 x Emergency Jumper Cable Clip, 1 x Type-C Cable, and 1 x User Manual.

Allow the unit to cool down for a few minutes before resuming inflation.)
