Boost X GBX45: 1250A UltraSafe Jump Starter Power Pack – 12V Car Battery Booster, Portable Power Bank & Jump Leads - For 6.5L Petrol and 4.0L Diesel Engines

Picked this up for van stash and roadside backup—wanted something that could fire up a flat battery without dragging out jump leads or waiting for help. The GBX45 delivers. 1250A peak current is no joke—started a diesel van and a 2.0L petrol car with zero drama. No sparks, no hesitation. Lithium build keeps it light, and the casing’s rugged—feels like it can take a knock. USB-C input/output means it doubles as a power bank too—charged a phone and a torch off it while camping. LED light’s bright enough for night work, and the clamps are solid—no flex or cheap feel. Good stash-ready gear for anyone who wants peace of mind on the road without the faff. 👍 Pros ✅ 1250A peak—starts most cars and vans easily ✅ USB-C power bank—charges phones and gear ✅ UltraSafe tech—no sparks or reverse polarity risk ✅ Compact and rugged—easy to stash in boot or cab ✅ LED work light—handy for night use or emergencies 👎 Cons ❌ Premium price—worth it if you want reliability ❌ No hard case included—store carefully ❌ USB-C cable only—no wall charger in box ❌ Not for heavy-duty trucks—check your engine size 🧭 Personal Review If you want a jump starter that’s compact, powerful, and built for real-world use, the NOCO GBX45 earns its spot. I’ve used it across van setups, roadside calls, and weekend trips—no drama, just clean starts and solid backup. Proper stash-ready gear for anyone who wants their battery sorted and their gear charged.

Excellent product, just connect it to the battery & vehicle starts at first attempt even if the battery was dead flat. Been checking it every so often & unit holding its charge well.

Fantastic piece of kit and great quality, super easy to ease with its compact size! Always have problems with my Mercedes vito van battery going completely dead to the point of not even operating the central locking when it’s been stood more than 5 days or so and this device jump started it effortlessly !!!! Highly recommend, worth every penny!!

Brilliant bit of kit got me out of a few situations definitely well worth keeping in your vehicle on long journeys as I found out, got me off the m25 to the services when the cars alternator gave up, great for jump starting vehicles

Does the job but when the battery fully dead doesn’t help

I recently purchased the NOCO Boost X Battery-Powered Car Jump Starter, and I must say, it exceeded all my expectations! This little device turned out to be an absolute game-changer on its very first day of use. First and foremost, the jump starter's compact size is incredibly convenient. It easily fits in my car's glove compartment, making it readily accessible whenever an emergency arises. I was initially skeptical about its power, but it proved me wrong. The jump starter delivered an impressive burst of energy, quickly reviving my dead car battery and getting me back on the road in no time. One feature that I particularly love about this jump starter is its built-in safety measures. It boasts intelligent jumper cables with spark-proof technology, which eliminated any worries I had about potential accidents. Additionally, the device offers reverse polarity protection, ensuring foolproof connections and preventing damage to my car's electrical system. Another standout aspect is the built-in flashlight. On the first day, I found myself stranded on a dark road, and the powerful LED light provided by the jump starter proved to be a lifesaver. It illuminated my surroundings brilliantly, allowing me to jump-start my car safely and with ease. The battery life of this jump starter is truly impressive. Despite using it to start my car multiple times, it retained a significant amount of power. It even comes with a USB port, allowing me to charge my phone or other devices on the go. It's like having a portable power bank for emergencies. Lastly, the overall build quality and design of the jump starter are top-notch. It feels sturdy and durable, instilling confidence in its longevity. The clear and user-friendly instructions helped me understand its functions quickly, even as a first-time user. To sum it up, the NOCO Boost X Battery-Powered Car Jump Starter has been a revelation. Its reliability, compactness, safety features, and versatility make it an indispensable tool for any vehicle owner. Whether you're facing a dead battery or need some extra power on the road, this jump starter is an excellent investment. I highly recommend it to everyone for its outstanding performance and peace of mind it provides in emergency situations.

Product that I received was faulty but manufacturer replaced it with a working one that is excellent. I had the product in my car for 11 months before I needed to use it because my car would not start, it was then that I found the NOCO Boost to be faulty. The product has a 12 month warranty, so I was lucky that I had to use it in 11 months!!!! So I suggest you test yours as soon as you buy it. Make sure the lights chase and the 12 volt clear light illuminates. Service support from the USA was very good and the replacement unit is excellent .

Very dangerousGot woke up yesterday morning to a pop.An all the final alarms going off.It was on charge normally over night and it decided to explode, fill my house with gas and smoke and set fire to the wall and our armchair.While me, my wife and my ten month old baby were upstairs but reached out to the company and day only offered me 35% discount on the same model. Very disappointed, end up very shaken up just lucky we where home or it could

Lightweight, USB chargeable, good power for jump starting. Use it for my car and boat.

Great product. I’ve since bought a second to go in my wife’s car. I have a 3 litre diesel Ute & this battery pack starts it up with ease & has done a few times. Have used it so many times I’ve lost count. We have 1 car, 1 Ute & 3 motorcycles at our house & every so often a battery is flat. Wouldn’t want to be without it now. Highly recommended.

Booster de qualité américaine. Fiable, indispensable dans l'auto. Construction robuste, sert de batterie de secours pour charger un smartphone et de lampe d'appoint pour éclairer en cas de panne.

Wir haben es schon einige Mal benutzen müssen. 4L Benziner . Top Produkt . Recht schnell aufzuladen über USB C . Immer wieder gern

Genial. Vale cada centavo. Tuve oportunidad de utilizarlo a los pocos dias de la compra. Es muy fácil de usar, efectivo, inmediato. Al primer intento de usarlo encendí mi auto sin ayuda. Me parece una excelente compra. Pequeño para traer en el auto, ademas permite ayudar a otras personas sin tantas dificultades de acomodar los autos etc. De ahora en adelante lo traeré siempre con mis cosas de emergencia en el coche. Ah y lo cargue en menos de una hora con un cargador de 30 w, y puede usarse uno de 60w. sin problema.
