• If the iOnBoost is overloaded while in the jumpstart mode, quickly disconnect the negative
then positive clamps. All functions on the iOnBoost will not operate if the unit was
overloaded. To recover from overload, let the unit rest for 10 minutes then plug it into a
power source for a few minutes to reset the unit.
Jumpstart Procedure
1. Turn off the vehicle ignition and all accessories (radios, lights, air conditioners), and
disconnect electronic devices.
2. Set the emergency brake and put vehicles with automatic transmission in park position.
3. Determine the polarity of the vehicle’s battery terminals. The positive (POS, P, +) battery
terminal usually is red and the negative (NEG, N, −) terminal is usually black. If you are
unsure, first refer to the vehicle owner’s manual. Make sure the negative battery terminal is
also connected to the vehicle frame.
4. Insert the orange plug of the jumper cables into the iOnBoost’s jumper terminal. When fully
inserted, the red and green lights on the cable safety block should both flash alternately.
Use only the jumpstarting clamps provided in this package� Unauthorized parts may
cause serious damage or injury�
5. Securely connect the positive (+) red clamp to the positive (POS, P, +) terminal of the vehicle
battery or the remote positive (+) terminal if equipped.
6. Securely connect the negative (−) black clamp to a non-moving, metal part of the engine or
frame as far away from the vehicle battery as possible.
7. When the clamps are properly connected to the battery, the green light on the cable safety
block will illuminate (a three-second delay is normal). When the light illuminates steady
green, it is safe to proceed in these instructions. If the light fails to illuminate steady green or
if any red lights illuminate, consult the troubleshooting section of this manual.
8. Place unit on a secure surface away from moving parts.
9. Start vehicle engine. Stop if the vehicle does not start after 3 to 4 seconds of engine
cranking. Wait 3 to 4 minutes, then try again. If engine does not start after second attempt,
discontinue cranking and consult a professional.
10. The internal safety timer will automatically disconnect the circuit after 90 seconds to
prevent the vehicle battery from reverse charging the unit. Both the red and green lights
will illuminate steady. If your vehicle still has not started, disconnect the cables and try the
procedure again.
11. When finished, disconnect the clamps in reverse sequence of connecting procedure—
first disconnect negative (black), then positive (red) clamps. Do not let the clamps touch
each other.
12. Disconnect the jumper cable assembly from the unit.
13. When convenient, completely charge the iOnBoost battery.
14. Store the unit and charge adapters in a cool, dry environment, away from flammable
materials. Remember to fully charge the unit every three months.
