Safety Information
Always follow safety guidelines to prevent electrical shock, explosion, or fire. Improper use can cause serious injury or damage. Read the manual carefully before operating the device.
Precautions and Warnings
Always follow safety guidelines to avoid electrical shock, explosion, or fire. Never connect the GB70 to non-12V lead-acid batteries or non-traditional systems. Avoid touching battery clamps together, as this can generate sparks. Do not use the device near open flames or sparks. Keep the GB70 away from water and extreme temperatures. Ensure proper polarity when connecting to batteries to prevent damage. Use the Manual Override feature with caution, as it disables safety protections. Improper use can result in serious injury or device damage. Read the manual thoroughly before operation.
Correct Usage Guidelines
Ensure the GB70 is fully charged before use. Verify the vehicle has a 12-volt lead-acid battery and identify correct polarity terminals (positive marked as POS/P, negative as NEG/N). Connect clamps securely to battery posts, avoiding carburetors, fuel lines, or thin metal parts. For most vehicles, follow negative ground system instructions; reverse for positive ground systems. Do not connect clamps to each other or non-recommended surfaces. Start the vehicle immediately after connection; if it doesn’t start, wait 20-30 seconds before retrying. Limit to five jump attempts within 15 minutes, allowing the GB70 to rest for 15 minutes between uses. Always refer to the vehicle’s manual for specific instructions.
Charging the NOCO Boost GB70
Charge the GB70 via USB or 12V fast charging. USB charging uses a 2.1A port for efficient charging, while 12V fast charging offers quicker replenishment. Ensure full charge before first use for optimal performance.
USB Charging
Charge the GB70 using the included USB Charge Cable connected to the USB IN port and a powered USB source, such as an AC adapter, car charger, or laptop. The USB IN port supports up to 2.1 Amps for safe and efficient charging of the internal lithium battery. Charging times vary depending on the GB70’s discharge level and the power source used. For optimal charging, ensure the device is powered on and connected to a high-current USB port.
12V Fast Charging
For rapid recharging, connect the GB70 using the 12V Cable to the 12V IN port and a powered 12V AUX port, such as a cigarette lighter. This method provides 36W of power, significantly reducing recharge time. The 12V fast charge feature ensures quick replenishment of the internal lithium battery, making it ideal for on-the-go use. Always ensure the vehicle’s ignition is turned off during charging to avoid any electrical interference or safety hazards.
Jump Starting Process
The NOCO Boost GB70 is designed for jump starting 12-volt lead-acid batteries, with the ability to jump start batteries as low as 2-volts using the Manual Override feature.
Step-by-Step Instructions
Identify the battery terminals and ensure correct polarity. Connect the positive clamp to the positive terminal and the negative clamp to a metal surface or negative terminal.
If the battery voltage is below 2V, use the Manual Override feature by pressing and holding the red button for 3 seconds.
Start the vehicle. If it doesn’t start immediately, wait 20-30 seconds and try again.
Turn off the GB70 before disconnecting the clamps to ensure safety.
Avoid connecting clamps to thin metal or fuel lines, and never touch the clamps together.
For repeated jump starts, allow the GB70 to rest for 15 minutes between attempts.
Ensure the device is fully charged before use and follow all safety guidelines to prevent damage or injury.
Manual Override Feature
The Manual Override feature allows jump-starting batteries below 2V. Press and hold the red exclamation button for 3 seconds to activate. Use with extreme caution, as spark-proof and reverse polarity protections are disabled. Ensure clamps are connected correctly to avoid sparks or heat. This mode delivers high current (up to 2000A) and requires careful attention to polarity. If unsure, seek professional help. The White Boost LED will flash when active, and the Red Error LED will illuminate if connections are reversed. Power off the GB70 before disconnecting clamps for safety.
Best Practices for Jump Starting
Always fully charge the GB70 before use and ensure the battery voltage matches the vehicle’s system. Connect clamps to correct terminals, avoiding non-metal parts. Start the vehicle within 30 seconds of connection. If unsuccessful, wait 20-30 seconds before retrying. Limit to five attempts in 15 minutes, allowing the GB70 to rest afterward. Never touch clamps together or connect to non-battery metal parts. Use Manual Override cautiously and only on 12V lead-acid batteries. Follow all safety guidelines to prevent damage or injury.
Emergency Features
The NOCO Boost GB70 features an ultra-bright LED flashlight with seven modes, including SOS, Blink, and Strobe, and supports USB charging for emergency power.
LED Flashlight Modes
The NOCO Boost GB70 features an integrated ultra-bright LED flashlight with seven modes for versatility in emergencies. Modes include 100%, 50%, 10% brightness for energy efficiency, SOS for distress signaling, Blink for visibility, Strobe for disorienting effects, and Off to conserve power. The flashlight is accessed via the Power button. Each mode is cycled by pressing the button within 3 seconds. Lower brightness settings extend battery life, making it ideal for prolonged use.

Battery Status Indicators
The GB70 features four Charge LEDs (25, 50, 75, 100) indicating the battery’s state of charge. LEDs pulse when charging and solidify when the battery reaches the corresponding level.
Charge LEDs Explanation
The GB70 features four Charge LEDs (25, 50, 75, 100) that indicate the battery’s state of charge. When charging, the LEDs pulse, and when fully charged, the Green LED remains solid while others turn off. The 25 LED pulses when below 25%, solid at 25%. The 50 LED pulses below 50%, solid at 50%. The 75 LED pulses below 75%, solid at 75%. The 100 LED pulses below 100%, solid when fully charged. This system provides a clear visual indication of the battery’s charge level, ensuring users can monitor and manage the device’s power effectively. The LEDs also automatically shut off after seven hours to conserve energy.
Troubleshooting Common Issues
Common issues include reverse polarity, low battery voltage, or overheating. The Error LED blinks to indicate problems. Refer to the manual for specific solutions and safety guidelines.
Error Conditions and Solutions
The GB70 displays error conditions through LED indicators. Reverse polarity triggers the Red Error LED. Low battery voltage (below 2V) turns off the Boost LED. Overheating causes the Red LED to blink. Solutions include correcting polarity, using Manual Override for low voltage, and allowing the device to cool down. Ensure proper connections and avoid sparking to maintain safety. Refer to the manual for detailed troubleshooting steps to resolve issues effectively and safely. Always prioritize caution when addressing error conditions to prevent damage or hazards.
