This 4-in-1 multifunctional car emergency jump starter is an all-around roadside rescue device integrated with car jump starting, tire inflation, vacuum cleaning and LED lighting functions, powered by premium 3.7V high-rate polymer lithium battery with three capacity options: 8000mAh(29.6Wh), 10000mAh(37Wh), 12000mAh(44.4Wh).

1. Superior Product Advantages

All-in-one multi-function design eliminates the need to carry separate inflators, vacuum cleaners and flashlights, greatly saving storage space in vehicles. It delivers peak current up to 1000A and cranking current of 300-500A, capable of quickly igniting all 12V gasoline and diesel vehicles when the battery goes dead.

Dual-way PD30W fast charging is supported on the Type-C port, compatible with 5V/3A, 9V/3A and 12V/2.5A charging protocols. The additional 5V/2A USB output allows you to charge mobile phones, cameras and other digital devices anytime during outdoor trips.

Intelligent multi-mode inflation system covers multiple inflation demands: 0-58PSI for cars, 0-51PSI for motorcycles, 0-120PSI for bicycles and 0-14PSI for basketballs. With a maximum inflation pressure of 150PSI and air flow of 22L/min, it only takes a short time to fully inflate a standard 195/65/R15 tire from 0 to 36PSI. Built-in 5000Pa vacuum suction removes dust, sand and debris from car seats, carpets and camping gears efficiently.

Low-noise inflation design with running noise controlled below 85dB at 100cm distance, and the white LED lamp with 50LM brightness provides reliable lighting for night breakdowns and outdoor activities.

Wide temperature adaptability ensures stable operation in extreme environments: operating temperature ranges from -20℃ to 50℃, charging temperature 0℃ to 45℃, storage temperature -20℃ to 65℃. The lithium battery features over 1000 charge-discharge cycles for long service life, and all cells have complete overcharge, over-discharge, short-circuit and overheat protection circuits for safe daily use.

2. Exquisite Manufacturing Craft

The core battery adopts high-rate polymer lithium cell, which undergoes strict cell sorting, pressure testing and aging screening before assembly to guarantee consistent capacity and stable discharge performance under high current. The whole machine shell is made of high-strength wear-resistant ABS material with fine matte surface anti-fingerprint treatment, resisting scratches and corrosion during long-term vehicle storage.

All internal air pump components are precision die-cast and lubricated with high-temperature resistant grease to reduce mechanical friction and extend service life. The integrated digital display panel is injection-molded in one piece, with sealed waterproof and dustproof structure to adapt to muddy, damp outdoor working conditions. Every finished unit passes strict factory inspection including pressure calibration, current testing, inflation speed verification and temperature cycling test before delivery.

3. Wide Application Scenarios

Roadside vehicle emergency: Instantly start cars, pickup trucks, SUVs and motorcycles with dead batteries; quickly inflate flat tires during highway driving.

Outdoor camping & self-driving travel: Vacuum clean sand and dirt from car interiors, tents and camping tools; LED light for night camp setup and night vehicle maintenance.

Daily life use: Inflate bicycles, electric bikes, basketballs, footballs, swimming rings and inflatable cushions; act as portable power bank to charge mobile phones, power banks and small electronics during power outages.

Professional repair shop & fleet maintenance: Multi-functional integrated tool reduces equipment inventory for auto repair stores; suitable for regular inspection and emergency rescue of corporate vehicle fleets.
