Charging the Jump Starter

How do I check the battery level?

Press the Power Button:

Charging time depends on battery level and power source.

Why does charging appear slow?

This is normal.

The unit uses a controlled, cell-balanced charging system to:

Rapid Recharge Technology (RRT)

What is RRT?

RRT allows the unit to recharge from the vehicle after a jump start.

How does it work?

1. Start the vehicle
2. Leave clamps connected for 40 seconds
3. Unit recharges via alternator

RRT automatically stops once the unit returns to its original state of charge.

Jump Starting a Vehicle

Before retrying:

• Clamps are firmly connected

• Unit has sufficient charge
• Vehicle is 12V
• Engine size is within unit capacity

Cold weather may reduce performance — retry up to 3 times.

How many attempts are recommended?

What is Override Mode?

Override Mode is used when the battery is extremely low.
