How To Use

Charge the GB251

• The GB251 comes partially charged out of the box and needs to be fully charged prior to use.
• Connect the GB251 using the included 12V DC car charger or XGC4 wall charger to the 12V IN port.
• The time to recharge a GB251 will differ based on the discharge level and the power source used.
• Actual results may vary due to battery conditions and level of discharge.
• 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.

Connect to the Battery

• Recharge Time: 8.5 hours Charger Rating: 56W Internal Battery Level. Fully read and understand the vehicle owner’s manual on specific precautions and recommended methods for jump starting to occur.
• 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 GB251 is for jump-starting 24-volt lead-acid battery systems only.
• Before connecting to the battery, verify that you have a 24-volt lead-acid battery system. The GB251 is not suitable for any other type of battery.
• Connect the positive (red) battery instructions below the positive (POS, P,+) battery terminal and the negative (black) battery clamp to the negative (NEG, N,-) battery terminal or vehicle chassis.

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.
3. If you are properly connected to the battery, the white boost LED will illuminate, and the battery charge LEDs will chase.
4. A 60-second countdown will begin as soon as a jump-startedmpfor -starting the vehicle.
5. Most vehicles will immediately start. Some vehicles may require the GB251 to be connected for up to 30 seconds before starting.
6. If the vehicle does not start right away, wait 20-30 seconds and try again.
7. Do not attempt more than five (5) consecutive jump starts within a fifteen (15) minute period.
8. Allow the GB251 to rest for fifteen (15) minutes before attempting to jump-start the vehicle again.
9. Once you have started your vehicle, disconnect the battery clamp and remove the GB251.

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 andhond the internal battery charge LEDs will indicate the current charge level of the unit. To reset the jump-starting function, press the power buthave 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

EN The GB251 is designed to jump-start 24-volt lead-acid battery systems down to 3 volts. If your battery is below 3 volts, the boost LED will be “off”. This is an indication that the GB251 can not detect a battery. If you need to jump start a battery below 3 volts, there is a manual override feature, which allows 3 volts to force “on” the jump star3 voltsion. If the battery is below 3 volts, the boost LED will be off, and the voltmeter will not display a voltage.

Powering Your USB & 12V Devices

The GB251 has (2) USB-OUT ports and a 12V-OUT port (12V AUX/ cigarette lighter port). Plug in any standard USB device 3 device (Up to 15A) and turn the GB251 “on” to start powering your devices.

Interface

1. Internal Battery Level indicates the charge level of the internal battery.
2. Hot LED Illuminates soli: indicates it is fully operational, but approaching upper temperature limit. Flashing red; the unit is too hot to jump start, and only the flashlight is available in this state.
3. Cold LED illuminates solid blue; unit is fully operational, but approaching lower temperature limit. Flashing blue, the unit is too cold to jump start, and only the flashlight is available in this state.

FAQs

Q: Can the GBX55 be used as a power bank?

Indeed. Phones, tablets, computers, and other small electronics can be charged with the GBX55’s 12V output and USB output connectors. Verify the power requirements and device compatibility at all times.

Q: How long can the GBX55 hold a charge?

It can run for up to a year without using it when completely charged. For best results, check the battery frequently and recharge it every six to twelve months.

Q: Can the GBX55 be used on multiple vehicles in succession?

Yes, but to avoid overheating and a guaranteed steady power supply, let the jump starter rest for 30 to 60 seconds in between jump starts.

Q: Can I use the GBX55 on lithium-ion vehicle batteries?

Yes, ordinary 12V lead-acid, AGM, and lithium-ion batteries can be used with the GBX55. However, before jump-starting, carefully consult the manufacturer’s instructions.

Q: Is it safe to leave the jump starter connected to a vehicle battery?

No, only attach when the car is jump-starting, and take it off as soon as it begins. It may overheat or short circuit if left connected.

Q: How many jump starts can I short-charge?

Depending on engine size and battery condition, the GBX55 can deliver up to 20 jump starts for small cars or 5–10 jump starts for bigger cars when fully charged.

Q: Can the GBX55 charge multiple devices at once?

It does indeed include 12V and USB outlets. While keeping the jump starter ready for use in an emergency, you can charge a phone or tablet. Steer clear of high-power devices at the same time to avoid overloading.
