NOCO Boost X GBX55: 1750A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 7.5L Gas and 5.0L Diesel Engines

1. Functionality: Works very well for my use. So far, I've used it twice on my 2012 Honda Civic when the temp was -10F and my car wouldn't start. Plug it in, light was chasing, started the engine, boom, works like a charm. 2. Jump Capability: Since I've only used it twice, and on my 2012 Civic, small car, I don't really know how well it works with SUVs & Trucks, but I would hope it work. Will update later if I use it to help out friend's cars. 3. Battery Life: Fully charged, used it twice within two months, drained the battery to half or so, if I remembered correctly. So, I would say you could use it to jump start about 4-5 small cars. Not sure about bigger cars. 4. Ease of use: VERY VERY easy to use. Self-explanatory. Make sure you read up on it or watch video on YouTube on how it work, especially if the battery is completely dead and the light is not chasing and you have to use the "Override" mode. 5. Compactness: VERY VERY compact. I put in my work backpack and bring it with my to work every day in case my car or a friend/coworker's car broke down due to battery drain or something. Or in the sever cold weather of -10F or below and car doesn't start. Overall, I would say it's very useful. Choose your own model and go down if you have to to save money. I bought the NOCO Boost X GBX55 1750A 12V model because I want it to be at least strong enough for my Tundra.

The NOCO Boost GBX55 is a beast! It jump-starts my car and truck with zero effort, even in cold weather. Super easy to use, holds a charge forever, and the build quality is top-notch. I love the USB-C fast charging and bright LED light too. Definitely one of the best tools to keep in your car — total peace of mind.

Started my 2011 Ford F150 Lariat Super Crew v8 5.0 without issue. Battery was completely dead. I did not check voltage but no lights on entry and no power locks. Connected my fully charged Noco that has been in the vehicle for 2-3 months. Power on. Counted to 40. Truck started as if it was fully charged. -I have about (12) Noco products. None of them have cause me issue or hesitation. The Noco GB40 took some extra work to start the truck in the past. It works well on my V8 4.6, my v6 3.5 and my v6 3.0. The 5.0 is just a little larger and seemed to tax the GB40. First (2) of these specific units were bought from a refurbished. Both were dead on arrival. Bought a new unit. Brand new. No issues.

Bought it Jul 26, 2025. Went to pull it out of the glove box after xmas and jumped a stranded full sized truck. Good stuff

The NOCO Boost X GBX55 has officially earned a permanent spot in my car. I’ve used it multiple times already—from jump-starting a completely dead SUV battery to helping a friend with a diesel truck and it hasn’t failed once. The power this thing delivers is impressive for such a compact device. What really sets it apart is the ease of use and safety features. It’s nearly foolproof no sparks, no confusion, just connect and go. The USB-C fast charging is a game changer, and the built-in flashlight is surprisingly bright. It also doubles as a power bank, which is super handy when you're off the grid or during a power outage. If you drive anything especially in cold climates or long trips this is a smart investment. Peace of mind in your glove box!

Another dead unit. I think the unit works good when it worked but after light use and 14 months it's completely dead and will not take a charge. I understand there's a year warranty but I would not buy this thing again without a seriously longer warranty. Again this was used lightly in my garage or driveway. This was not a unit that traveled around or was used for commercial purposes. I probably used it 8 times at most. Lots of death of the Noco on YouTube. I'm surprised that they don't have a mechanism to swap it out even if I had to pay a surcharge. Maybe that's a hint to Noco as I would be willing to pay a $40 surcharge or something just swap it out for a new one

Jump starter works great, lite weight, and has alot of power. Would buy the power plug if you want it to charge faster. If not it will charge slow.

The first NOCO booster shipped failed to fully charged. NOCO shipped out a replacement fast. The replacement charges properly and I am satisfied.
