Jump-Starting Procedure

Follow these steps carefully.

Ensure jump starter is charged (display shows at least 50%).
Turn off both jump starter and vehicle ignition.
Connect red clamp to positive (+) terminal of dead battery.
Connect black clamp to a clean, unpainted metal part of vehicle frame or engine block (away from battery).
Turn on jump starter (press POWER button).
Start vehicle. If engine does not start within 5 seconds, wait 30 seconds before retrying.
Once vehicle starts, turn off jump starter.
Remove black clamp first, then red clamp.
Recharge jump starter as soon as possible after use.

Tip: If vehicle fails to start after 3 attempts, battery may be damaged or other issues exist.

Using USB Ports & LED Light

USB Charging: Connect device using USB cable. Ports automatically detect device and deliver optimal current. Do not exceed 2.1A total across all ports.

LED Light: Useful for emergency lighting or roadside repairs. In SOS mode, light flashes in international distress pattern.

Note: Using USB or light will drain internal battery. Recharge after extended use.

Maintenance & Storage

Recharge every 3 months if not used. Store in a cool, dry place away from direct sunlight.

Keep clamps clean and free of corrosion.
Wipe case with a dry cloth. Do not use chemicals or water.
Check charge level monthly. Recharge if below 50%.
Do not disassemble unit. No user-serviceable parts inside.

CAUTION! Do not store in temperatures below -4°F or above 140°F. Extreme temperatures reduce battery life.
