How To Use
Charge the GBX75.
The GBX75 comes partially charged out of the box and needs to be fully charged prior to use. Connect the GBX75 using the included USB-C Charge Cable or 12V Car Charger to the USB-C IN/OUT port. It can be recharged from any powered USB port, like an AC adapter, car charger, laptop, and more. The USB-C IN/OUT port utilizes Power Delivery 3.0 technology capable of receiving/delivering up to 60W. The time to recharge a GBX75 will differ based on the discharge level and the power source used. Actual results may vary due to battery conditions.
Recharge Time: Charger Rating: 1.7h 60W Fast Charge. When recharging, the charge level of the internal battery is indicated by the charge LEDs. The LEDs will slowly pulse ‘on’ and ‘off’ and become solid until all four charge LEDs are on. When the battery is fully charged, the green 100% LED will be solid, and the 25%, 50%, and 75% charge LEDs will turn «off». From time to time, the green 100% LED will pulse indicating maintenance charging is occurring.
The GBX75 is equipped with fast charging technology that allows it to be recharged at a rate of up to 60W. A compatible charger, capable of 60W USB-C Power Delivery 3.0, is required to fully utilize this feature. The fast charge LED will illuminate when rate of charge exceeds 15W, indicating USB Power Delivery 3.0 is active.
The most effective way to charge GBX75 is by using The NOCO Auto Charger (not included). NOTE: The vehicle must be On / Running for the Auto Charger to Fast Charge the unit.
Connect to the Battery.
Carefully read and understand the vehicle owner’s manual on specific precautions and recommended methods for jump-starting the vehicle. Make sure to determine the voltage and chemistry of the battery by referring to your battery owner’s manual prior to using this product. The GBX75 is for jump-starting 12-volt lead-acid batteries only. Before connecting to the battery, verify that you have a 12-volt lead-acid battery. The GBX75 is not suitable for any other type of battery.
Identify the correct polarity of the battery terminals on the battery. The positive battery terminal is typically marked by these letters or symbols (POS, P,+). The negative battery terminal is typically marked by these letters or symbols (NEG, N,-). Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts. The below instructions are for a negative ground system (most common). If your vehicle is a positive ground system (very uncommon), follow the below instructions in reverse order Connect the positive (red) battery clamp to the positive (POS, P,+) battery terminal, and the negative (black) battery clamp to the negative (NEG,N,-) battery terminal or vehicle chassis.
Make sure all of the vehicle’s power loads (headlights, radio, air conditioning, etc.) are turned off before attempting to jump-start the vehicle. 2. Press the power button to begin to jump-starting, and all LEDs will flash once. If you are properly connected to the battery, the white boost LED will illuminate and the battery charge LEDs will chase. A 60-second timeout countdown will begin as soon as a battery is detected. 3. Try starting the vehicle.
Most vehicles will immediately start. If the vehicle does not start right away, wait 20-30 seconds and try again. After the 60-second timeout is complete, the unit must be powered off, then back on, to initiate a new jump-start sequence. Do not attempt more than five (5) consecutive jump starts within a fifteen (15) minute period. Allow the GBX75 to rest for fifteen (15) minutes before attempting to jump-start the vehicle again. 4. Once you have started your vehicle, power off the unit, disconnect the battery clamps, and remove the GBX75.
A 60-second countdown will be initiated as soon as a battery is detected. After 60 seconds have elapsed, the jump-starting function will be disabled. The boost LED will turn off and the internal battery charge LEDs will indicate the current charge level of the unit. To reset the jump-starting function, press the power button to power off the unit. Press the power button again to power on the unit and restart the jump-starting function.
Low Voltage Batteries & Manual Override.
The GBX75 is designed to jump-start 12-volt lead-acid batteries down to 3 volts. If your battery is below 3 volts, the Boost LED will be «off». This is an indication that the GBX75 can not detect a battery. If you need to jump-start a battery below 3 volts there is a manual override feature, which allows you to force «on» the jump-start function.
- Power LED Illuminates White when unit is «On». Will illuminate orange after the 60-second timeout countdown until the clamps are removed from the Car Battery or the GBX75 is power cycled ‘off’ and back ‘on’ again.
- Power Button Push to turn unit «on» & «off» or restart boost after 60-second timeout.
- Reverse Polarity Error LED Illuminates red if reverse polarity is detected.
- Cold LED Illuminates solid or flashes blue when internal temperature is too low.
- Hot LED Illuminates solid or flashes red when internal temperature is too high.
- Error LED Blinks “on” and “off” in various sequences (from 1 to 6 blinks) to convey error conditions.
- Internal Battery Level Indicates the charge level of the internal battery.
- Light Mode Button Toggles the ultra-bright LED light through 7 light modes: 100% > 50% > 10% > SOS > Blink > Strobe > Off
- Boost LED Illuminates white when boost is active. If the unit is connected properly to a battery, the GBX75 will automatically detect a battery and go into boost mode (LED flashes white when manual override feature is active).
- Manual Override Button To enable, push and hold for three (3) seconds. WARNING: Disables safety protection and manually forces
Boost «On». Only for use when a battery voltage is too low to be detected.
- Fast Charge LED Illuminates white when fast charge is active. Fast charge LED turns red (solid/blinking) when there is an error
