Dead Battery. Dark Road. Freezing Rain. You're the Hero in the Parking Lot.

It's 6:00 a.m. The engine clicks once. Then nothing. Your phone says roadside assistance is 90 minutes away. But you've got the GBX155 sitting in your trunk. You open the hood, clamp the cables onto the terminals, and press the button. The LCD screen lights up with battery status. You turn the key—and that 8-liter diesel roars to life like it just rolled off the lot. This isn't just a jump starter. It's your independence from tow trucks, good Samaritans, and the sinking feeling of being stranded. When everyone else is waiting for a jump, you're already on the highway.

 
 

4250 Amps – Wake Up the Biggest Engines on the Road

This isn't a toy for scooters and lawn mowers. The GBX155 delivers a brutal 4250-amp peak current that cranks 10.0-liter gasoline engines and 8.0-liter diesel engines without breaking a sweat. Full-size trucks, heavy-duty SUVs, commercial vans, tractors, boats with massive V8 inboards—this one unit handles them all. The heavy-gauge, spark-proof clamps bite through corrosion and deliver power where it counts.

Smart Fully Automatic Charger – Rescue, Then Restore

Once your engine is running, the GBX155 doesn't stop working. Connect it to your battery with the included clamps, and the 4-amp smart charger takes over. It automatically diagnoses your battery's health, selects the correct charging mode, and brings even deeply discharged batteries back from the dead. Overcharge protection, reverse polarity alarm, and spark-proof technology mean you can connect it in the dark, in the rain, without a second thought.

LCD Intelligence – See Exactly What's Happening

The bright, backlit LCD screen displays battery voltage, charge percentage, charging mode, and fault codes in real time. No guessing. No cryptic blinking lights. Just clear, readable data that tells you the state of your battery before, during, and after every use. It's the control center that transforms a jump starter into a complete battery management system.

Power Bank for Life on the Road

When you're not using it to revive dead engines, the GBX155 doubles as a high-capacity power bank. Dual USB ports charge your phone, tablet, GPS, or any USB-powered device multiple times on a single charge. It's your emergency communication lifeline when you're stuck in the middle of nowhere with a dead phone and no signal.

What's Inside: Engineered for Crisis, Not Just Convenience

The high-discharge lithium battery pack holds its charge for up to 12 months on standby, so it's ready when you forgot to check. The spark-proof, reverse-polarity protection system means you literally cannot hook it up wrong—the LCD will flash a warning and prevent any current from flowing. The reinforced rubberized housing is drop-proof, dust-proof, and water-resistant. Heavy-duty copper clamps and thick silicone cables stay flexible at -4°F and won't crack in the cold. This is the unit that lives in the back of trucks, tucks into boat compartments, and gets handed down to the next driver because it refuses to die.

  • New technology and super fast recharge

    The difference is in the shorter charging times and the powerful jump start delivering the same power on every start This will more than start my Ford Ranger on a Cold winter day and can be used as a power bank in between I’ve have a jump starter in each of my vehicles and have had many over the years and this one has by far a better capacity and specification Please I spent the money on this one

  • Awesome little package

    Fantastic portable jump starter, got this little unit on special and it doesn’t disappoint, got handy features like a torch if you goofs jump starter of a night time, ports so you can charge your device. Ip65 water and dust resistant, 5 minute quick charge feature. Can’t go wrong grabbing one of these handy for your vehicle or if you see someone who needs a jump start. 👍

  • Piece of mind

    I purchased the Boost Lithium charger 1750A to predominantly start my ride-on, it does this with ease time after time and I still have not had to recharge it, I have now also used it to start a car with a flat battery when shopping - so far I can not fault it, top quality, easy to use, compact and always ready to go. I am very happy I purchased it.
