K40 5000A Portable Car Battery Jump Starter Pack for Up to 10.0L Gas and 9.0L Diesel Engines with Smart LED Display

Overview:

A dead 12V vehicle battery can leave drivers stranded without warning. Relying on traditional jumper cables requires a second vehicle and creates electrical risks if connected improperly.

The K40 5000A Portable Car Battery Jump Starter provides an independent emergency jump-starting solution for heavy-duty gas and diesel vehicles. Delivering up to 5000A peak current, the K40 easily turns over dead batteries on engines up to 10.0L and diesel engines up to 9.0L. Designed with a real-time digital voltage monitoring display, 10 intelligent safety protections, a manual BOOST override function, 12V DC power output, fast USB charging ports, and a 300-lumen LED flashlight, it serves as an all-in-one power station for cars, trucks, RVs, and marine vessels.

Primary Applications & Compatibility:

Designed for 12V automotive and heavy-duty battery systems:

Large Vehicles (Up to 10.0L): Full-size trucks, SUVs, commercial vans, muscle cars, and sports cars.

Diesel Engines (Up to 9.0L): Diesel pickup trucks, RVs, tractors, commercial haulers, and motorboats.

Everyday 12V Equipment: Suitable for cars, motorcycles, lawnmowers, ATVs, and marine craft using standard 12V lead-acid batteries.

Key Features:

5000A Peak Jump-Starting Output: Instantly restarts dead 12V batteries on high-displacement engines up to 10.0L gas and 9.0L diesel.

Real-Time Voltage & Status Screen: Large smart display tracks vehicle battery voltage, unit charge state, clamp connectivity, and warning alerts in real time.

10-Point Intelligent Safety System: Built-in safeguards protect against short circuits, reverse polarity, over-charging, over-current, reverse charging, extreme temperatures, over-voltage, overload, and sparks.

One-Button Manual BOOST Mode: Allows manual power override to force start severely discharged or zero-voltage batteries.

Multi-Port Power Bank & Flashlight: Includes USB-A and Type-C 3.0A outputs, a 12V DC power port, and a 300-lumen 3-mode LED light (Flashlight, Strobe, SOS)..
