How To Use

Step 1: Charge the GBX55
The GBX55 comes partially charged out of the box and needs to be fully charged prior to use. Connect the GBX55 using the included USB-C Charge Cable 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 GBX55 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 occurring.

Fast Charge.
The GBX55 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 the rate of charge exceeds 15W, indicating USB Power Delivery 3.0 is active.

Auto Charger
The most effective way to charge GBX55 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.

Power Source
When charging USB devices, it is important to power on the GBX55 unit first and then plugs in the USB device being charged.
NOTE: If the GBX55 unit is not powered on first, it will drain power from the USB device, if it is DRP compatible. To charge GBX55 with a DRP compatible device (e.g phone, laptop, power bank) ensure GBX55 is powered OFF before making a cable connection between GBX55 and the DRP device.

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 GBX55 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 GBX55 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.

1. 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.

Step 3: Jump Starting.

1.  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 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 GBX55 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 GBX55.

60-Second Timeout.
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.

CAUTION.
A 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 GBX55 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 GBX55 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 MODEL USES A VERY HIGH CURRENT (UP TO 1750 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.
