Features
Boost X Lithium Jump Starter: The Noco Boost X GBX75 is a portable lithium-ion battery jump starter pack that delivers 2500-amps for jump starting a dead battery in seconds. The Boost X GBX75 powerful lithium jump starter features Noco's latest PX Lithium Technology that delivers incredible power, ultra-fast charging, and unmatched versatility. Its designed for cars, boats, RVs, trucks, and more, with gas engines up to 8.5 liters and diesel engines up to 6.5 liters.
12V Lead-Acid Battery Compatible: The GBX75 is designed to jump start 12-volt lead-acid batteries, including Wet Cell, Gel Cell, AGM, EFB, and MF types. Applications include automobiles, marine craft, RVs, trucks, vans tractors, and more.
UltraSafe 2.0 Protection: The Noco jump starter features enhanced patented safety technology that provides spark-proof connections and reverse polarity protection making it safe and easy for anyone to use.
Jump Starting: After connecting the fully-charged Noco GBX75 to the battery, most vehicles will immediately start. If the vehicle does not start right away, wait 20-30 seconds and try again. Do not attempt more 5 consecutive jump starts within a 15 minute period. Allow the GBX75 to rest for 15 minutes before attempting to jump start the vehicle again. A 60-second timeout is initiated as soon as the GBX75 is connected to a battery. After 60 seconds has elapsed with no charging activated, the jump starting function will be disabled. Powering the jump started Off and On again will reset the unit. 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.
Heavy-Duty Battery Clamps: The included heavy-duty battery clamps span up to 32" in length, and are capable of reaching most battery posts or chassis ground. It features a high-temperature silicone wire insulation that remains extremely flexible down to 0°F and withstands high levels of duress and even prolonged exposure to high temperatures.
USB-C Input/Output & USB-A Output: The Noco GBX75 is equipped with a 60W USB-C Input/Output port with Power Delivery (PD) 3.0 technology, providing lighting-fast recharges with compatible chargers (sold separately). The USB-C Power Delivery port can also be used for charging USB-C devices, like smartphones, tablets, laptops, wearables, and more, with up to 60 watts of available power. A USB-A Output is also provided for charging devices, with 2.1A of available power. Using the USB-C Input/Output port, the jump starter can be recharged using the Noco U65 65W USB-C Charger (sold separately), or from a powered USB port, AC adapter, or the included USB car charger. Using USB-C Power Delivery 3.0, the GBX75 can be fully recharged in approximately 1.7 hours and go from 0% to jump starting with 5 minutes of charge. Typical recharging times include:
Charger Rating | Recharge Time |
---|---|
60W (USB-C or Auto Charger) | 1.7 Hours |
10W | 10 Hours |
5W | 20 Hours |
2.5W | 40 Hours |
Notes:
- GBX75 recharging times will vary based on the discharge level and the USB power source used.
- The GBX75 comes partially charged out of the box and needs to be fully charged prior to use.
- When charging USB devices, it is important to power On the GBX75 first before plugging in a USB device. If the USB device is DRP compatible, the GBX75 will drain power from the device, if the jump starter is powered Off.
Charge LEDs: The GBX75 has four Charge LEDs - 25%, 50%, 75% and 100%. These Charge LEDs indicate the internal battery's state-of-charge (SOC).
- The 25% Charge LED will pulse while charging and will be solid Red when the internal battery is 25% charged.
- The 50% Charge LED will pulse while charging and will be solid Red when the internal battery is 50% charged.
- The 75% Charge LED will pulse while charging and will be solid Yellow when the internal battery is 75% charged.
- The 100% Charge LED will pulse while charging and will be solid Green when the internal battery is fully charged.
400-Lumen LED Flashlight: The GBX75 feature's a built-in rechargeable, lithium-powered LED flashlight with seven light modes - 100%, 50%, 10%, SOS, Blink, Strobe, & Off. With multiple luminosity settings, it's immediately adaptable to a variety of situations. Use its powerful flashlight to help you see your engine, change a tire at night, or even warn oncoming traffic when disabled and in need of roadside assistance.
Simple User Interface: Noco designed the GBX75's user interface to be simple and easy to understand. LED status indicators display the internal lithium battery's charge level and charging status. Error indicators show when connected in reverse polarity or temporarily disabled for thermal protection. Or simply turn on the LED flashlight, recharge a USB device, or use manual override for deeply discharged batteries.
Rugged Compact Design: This compact, pocket-sized lithium jump starter is IP65 rated (with ports closed) to protect it against water, shock, dirt, and dust. It's smaller and lighter than traditional battery booster packs and conveniently stores in a glove compartment, center console, trunk, or toolbox.
Protection Circuitry: The GBX75 will display an Error Condition when a reverse polarity condition is present, a battery falls below 3 volts, or the internal battery is overheating. Individual Error LEDs will light, indicating the polarity is reversed or the internal battery is too hot or too cold. The Boost Light will not come on if the connected battery is below 3 volts.
