14.8V High-Performance Jump Starter with 6000mAh Capacity, Compact 406080 Lithium Battery for Cars & USB Devices, Portable Emergency Booster

Features

• Higher Voltage Architecture: Unlike standard 12V units, this jump starter utilizes a 14.8V lithium battery pack (4-cell configuration) that delivers superior cranking power and faster engine turnover compared to traditional 12V lead-acid batteries . The higher voltage ensures reliable starts even in challenging conditions.
• Compact & High-Density Design: The 406080 form factor packs 6000mAh capacity into a slim, space-efficient package, making it ideal for vehicles with limited storage space while maintaining sufficient power for emergency situations.
• Reliable Starting Performance: Provides adequate starting current for most 4-cylinder sedans and smaller 6-cylinder vehicles, making it a practical choice for daily drivers and compact cars.
• Multi-Function Utility: Serves as both a jump starter and a portable power bank for charging smartphones, tablets, and other USB devices via the standard USB output port.
• Essential Safety Protections: Features reverse polarity protection, short-circuit prevention, over-current limiting, and temperature control to ensure safe operation .

Specifications

Warnings & Precautions

Critical Connection Rules

• NEVER reverse-polarity clamp connections—incorrect connection can damage vehicle ECUs or trigger battery explosions.

• Always ground the negative (-) clamp to unpainted metal on the engine block or chassis, not directly to the dead battery's negative terminal.

• Ensure the jump starter is OFF before connecting clamps.

Jump-Starting Procedure

• Connect RED clamp to the positive (+) terminal of the dead car battery.
• Connect BLACK clamp to a clean, unpainted metal ground point away from the battery.
• Turn unit ON. Start vehicle (crank for 3-5 seconds maximum per attempt).
• After successful start, turn unit OFF and disconnect in reverse order.

Storage

• Test the jump starter's charge every 3 months to ensure readiness.

• Store at approximately 50% charge in cool, dry conditions for optimal battery life.

• Keep unit above -20°C to prevent lithium battery capacity loss.
