How To Use

1. Step 1: 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.
   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 occuring.

   • Fast Charge.
     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.

   • Auto Charger.
     The most effective way to charge GBX75 is by using The NOCO Auto Charger.
     NOTE : The vehicle must be On / Running for the Auto Charger to Fast Charge the unit.

   • Power Source.
     When charging USB devices, it is important to power on the GBX75 unit first and then plug in the USB device being charged.
     NOTE : If the GBX75 unit is not powered on first, it will drain power from the USB device, if it is DRP compatible. To charge GBX75 with a DRP-compatible device (e.g phone, laptop, power bank) ensure GBX75 is powered OFF before making a cable connection between GBX75 and the DRP device.

2. Step 2: 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 symbol (POS,P,+). The negative battery terminal is typically marked by these letters or symbol (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.

3. 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.

4. Step 3: Jump Starting.

5. Make sure all of the vehicle’s power loads (headlights, radio, air conditioning, etc.) are turned off before attempting to jump start the vehicle.

6. Press the power button to begin 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.

7. 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.

8. Once you have started your vehicle, power off the unit, disconnect the battery clamps, and remove the GBX75.

60-Second Timeout.
A 60-second countdown will be initiated as soon as a battery is detected. After 60 seconds has 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.

CAUTION.
60-SECOND TIMEOUT IS DISABLED WHILE USING MANUAL OVERRIDE MODE. POWER WILL CONTINUE TO BE SUPPLIED WHILE MANUAL OVERRIDE IS ACTIVE. TO MAXIMIZE THE NUMBER OF JUMP-STARTS, IT IS RECOMMENDED TO TURN OFF THE BOOST-UNIT AS SOON AS THE VEHICLE HAS STARTED.

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.

CAUTION.
USE THIS MODE WITH EXTREME CARE. THIS MODE IS FOR 12-VOLT LEAD-ACID BATTERIES ONLY. BOTH THE SPARK PROOF AND REVERSE POLARITY PROTECTION FEATURES ARE DISABLED. PAY VERY CLOSE ATTENTION TO THE POLARITY OF THE BATTERY BEFORE USING THIS MODE. DO NOT ALLOW THE POSITIVE AND NEGATIVE BATTERY CLAMPS TO TOUCH OR CONNECT TO EACH OTHER AS THE PRODUCT WILL GENERATE SPARKS. THIS MODE USES VERY HIGH CURRENT (UP TO 2500 AMPS) THAT CAN CAUSE SPARKS AND HIGH HEAT IF NOT USED PROPERLY. IF YOU ARE UNSURE ABOUT USING THIS MODE, DO NOT ATTEMPT AND SEEK PROFESSIONAL HELP.
