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

This has saved my bacon and my kids bacon too many times to count. Its intuitive, fast to charge, and doubles as a laptop/tablet/phone power battery. About the only thing I didn't like was the fabric pouch case, but there are several custom fit cases on Amazon for this model. These are so much better than the old bulky lead-acid jump packs. Fits nicely in glovebox. This one has multiple jumps per charge. If your on the fence about this let me pull you to the buy-it side.

This unit is rugged and well built, as it should be for the premium price. I've had my GBX55 for over 1.5 years and have never needed to use it, twice I've checked on the booster and found that it was half way discharged, and would put it on charge to top off. Well today the car battery was almost dead and my GBX55 let me down. It was again at half charge and would not jump the battery and when I put it on to charge, it displayed an error related to the charging circuit. Hat's off to customer service who responded quickly to my emails and being out of warranty, they offered me a 35% discount on my purchase of a new booster. But I had to respectfully decline, I never had to use my booster and it let me down when I needed it. I have no trust in NOCO boosters, what's to say that the next booster will not let me down in the same way, just when you need it. At the premium price they charge, I would have expected better life and reliability. I should have bought another Schumacher; the one I have currently, I've had for around 7 years and has always held its charge and has never let me down. It's bigger and bulky, but I'm sure they make a comparable one to the GBX55. And for the price, the TOPDON JS3000 looks to be a better value for the money!!

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!

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

Za pierwszym razem przyszedł nie ten produkt co zamówiłem. Po czasie dostałem odpowiedni i jest ok. Odpalałem już 6.0 v8 gdzie Alu był trup z cumminsem tez sobie dobrze radzi. Urządzenie póki co polecam

خفيفة الوزن وجميلة وعندما أستخدمها سوف أحدث هذه الصفحة مرة أخرى بمشية الله.

Robuuste en goede kwalteit startbooster. Geloof niet alle slechte verhalen over NOCO, dat zijn uitzonderingen die te veel zijn uitvergroot. NOCO is een van de meest bekende marktleiders in startboosters en maakt zeker geen rommel. Zelfs de Nederlandse ANWB pechhulp gebruikt dit merk! Ik heb met 1x opladen tot 4 keer en zonder enige problemen een 2.0 dieselmotor kunnen starten. Ook een dieselmotor met volledig lege accu kreeg ik gestart met de speciale lege accu functie. Het opladen gaat binnen 15-30 minuten als je een zwaardere USB-C lader met PD en goede USB-C laadkabel met PD gebruikt. (PD USB, oftewel USB Power Delivery (PD), is een universele snellaadstandaard voor USB-C-poorten die apparaten zoals smartphones en laptops sneller en veiliger kan opladen door de benodigde hoeveelheid stroom dynamisch aan te passen.)

Tengo vehículo con motor grande y lo encendió correctamente

es la hostia, me fui de vacaciones, y me quede con 2 coches sin bateria. Un toyota rav hibrido, y un toyota fj cruiser (4.000 gasolina V6) . Los arranque a la primera, además es muy rápido para recargarse, y las pinzas supercomodas, os recomiendo comprar el cargador del mechero, porque así despues de arrancarlo recargar el mismo NOCO en el propio coche... Y por supuesto, la funda, que es una pasada.
