NOCOBoost X GBX75: 2500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 6.5L Gas and 4.0L Diesel Engines

This thing is *seriously* awesome! I have several big vehicles, and even though this was rated for engines up to 8.5L, I was still skeptical that it could crank over their big batteries. Boy, have I been surprised! Even with a parasitic drain on my V10 Excursion, this allowed me fire the engine right up -- no waiting or anything.I've actually been most impressed though by the 'override' mode that allows the device to jump batteries that have been sitting for long periods in the cold and have effectively become depleted. I also have a Ford Expedition that had been parked for a couple months over winter. I recently tried to jump start it with cables using another truck, but to no avail. I then connected a trickle charger for 48 hours and it still wouldn't start. I had just about resigned myself to purchasing a new battery, but on a whim, I figured I'd give it a shot -- and after engaging override, it finally worked! As a result, it's already paid for itself. You can be sure that any time I have to leave my car in the airport parking garage for a few days, I'm going to have this in my trunk...cause it's a lousy feeling to get back into town just to have to call AAA in order to drive home. Needless to say, I'm a total NOCO fan boy now!

Tried 2 other brands and nothing. Connected this to my car and it started up immediately! Sticking with the brand till they prove me wrong. Stop shopping buy this one found it in a review done by Project Farms on Youtube.

I've had this for about a year now. My coworkers have the smaller versions. They never use them. They always ask to barrow mine, especially for larger trucks. F350's, 2500's, Denali's, Tundra's, connect and go. Can't go wrong with this particular size. Also very durable!

I rarely write reviews, but I feel compelled to share my experience with the NOCO GBX75 – especially after giving it two chances.The first unit I bought lasted just under two months before it literally caught on fire during normal use. Yes, you read that right – it caught on fire. This was incredibly frustrating considering NOCO heavily advertises these as “Ultra Safe.” What’s worse is their so-called warranty didn’t cover it. Turns out, you have to register the product first for the warranty to even apply – something they don’t make very clear up front.Still needing a jump box, I reluctantly bought a second GBX75, thinking maybe the first was just a fluke. Nope. Same poor performance. Despite all the marketing hype, both units could only jump about 7 to 8 times on a full charge before needing to be recharged – and that’s under ideal conditions. I originally thought the first unit was defective, but it turns out that’s just how low the actual capacity is.For the price, you’d expect reliable performance, solid safety, and a warranty you don’t have to fight for. Instead, I got two unreliable units, fire hazard concerns, and a huge dose of buyer’s remorse. I’ve completely lost trust in the NOCO brand after this experience.

Not only has it done a great job jumpstarting my Harleys, it also works as a great source for lighting when you lose power at American Legion's Boys State

NOCO is the only way to go! No more calling AAA are asking strangers for a jump.

Seemed to work pretty good, didn't spin the starter like i thought it would.

Well, this is been in my parts box and has only been used 4 times. The only thing I can really say is that started every vehicle. The engines seems to turn over stronger with the jump starter than with a fully charged in-vehicle battery.It is more expensive than many but my impression is this unit delivers what it says on the tin and am hopeful they are using high quality battery cells.Anyhow, I don't see anything that would keep me from recommend this jump starter.BT recommended
