I recently ordered this battery maintainer and it stopped working after I began using it. I was immediately shipped a replacement and the return was handled quickly.

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.

-15°F and my F-250 was dead at the job site. The GBX155 cranked the 6.7L Power Stroke on the second try and the LCD showed the battery was at 9 volts.

After sitting unused for several weeks, the unit still held most of its charge and was ready when another vehicle needed a jump.

We were packed for the lake and the Suburban wouldn't start. My husband grabbed the GBX155 and it fired right up. We also used it to charge our phones on the drive.

Cold-weather performance has been a strong point. The booster delivered reliable starting power during freezing conditions when a weak vehicle battery failed.

Doesn't have a screen but it works well. I'd like it better if it had a screen like my Nexpeak chargers, but this unit has been reliable.

I keep this on my fishing boat. When the battery died three miles from the dock, it jumped the 5.7L Mercruiser in seconds. The housing has handled salt spray without issues.

Strong starting power for large engines, plus the USB-C power-bank function, makes it useful as an emergency tool to keep in the vehicle.

I don't have time to wait two hours for roadside help. This jump starter gives me independence. I've used it on my minivan and helped a neighbor start her car too.
