NOCO 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.

I purchased this in 2024 and have only just had an occasion to use it. I charged it in 2024, and it was still fully charged in 2026, even after sitting in the boot of the car all that time. I was amazed by how easy it was to use, how small it was, and how well it performed. It started a vehicle with a dead battery so easily. Gone are the days of needing a second car and jump leads. Just connect this, turn it on, flashing array of lights, then a white light and off you go. Seconds. Thoroughly impressed, enough to write a review.

I bought this in October 2021, after my car battery had run flat at the train station after a weekend away, and the AA couldn’t get to me for at least 2hrs!! I have 3L diesel so needed something with some power. I’ve since used on my car 2 or 3 times, on a work colleague’s camper, and countless other vehicles, and not once has failed to perform. This truly is a great piece of kit, dead simple to use. No drama, no fuss, just does its job. I honestly don’t know how many jump starts it can do. For me, as a rule of thumb, I charge it back to full after I’ve used it, and I’ll periodically check it every 3 months or so, just for my own piece of mind. Expensive, I suppose yes, but the amount of times it’s got people going again, it’s money well spent tbh.

Awesome, starts cars and motorbikes instantly, also double as a battery bank for you USB devices

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.

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!!

Be warned, this automatically dies after a year!! Had on full charge and once a year was up (funny old thing the one year warranty...) it does. Doesn't charge, doesn't turn on. Amazon haven't replied to messages saying it's the product companies fault and Noco don't reply at all. Been used 0 times too!

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.

Wat een fijn product, het werkt zeer goed! Stevig en ligt goed in de hand en er zit ook verlichting op. Ik heb hem zelf een keer gebruikt in de winter en ook een keer mijn buurman geholpen die een grote truck heeft..1x starten en hij liep, echt een super ding en een gerust gevoel om in je auto te hebben liggen.

This is the sort of device that sits in your car forever with very occasional use (unless you are a road service provider). So it needs to hold its charge, handle variable temperatures, and work seamlessly when required. It achieves all of these aims. I bought the additional case to make sure it stays together and doesn't get damaged, and that's worth the extra (on sale). It sits behind my car's rear wheel well and gets pulled out on the rare occasions it's needed, when its simple and clear design makes it easy to operate without reading a big manual. Only downside is the price, but there's no point paying less and having no charge when you need it.

Ho preso questo avvitatore per sostituire il precedente di altra marca che dopo un po’ di tempo si era gonfiato. Ho scelto Noco perché é un’ottima azienda che produce prodotti di qualità e certificati. Nello specifico questo permette di avviare veicoli a benzina e diesel con batteria a 12V senza problemi. Ha sistemi di protezione contro scintille, inversione di polarità, oltre a una gestione termica e di potenza efficace. Integra una torcia a LED bianca con diversi effetti. Ho scelto questo dispositivo in particolare perché oltre alle varie caratteristiche, dispone di una porta USB C che torna comoda in ogni situazione, soprattutto considerando la potenza di uscita di 60W, che permette di alimentare anche un PC o a caricare velocemente smartphone e tablet. Un vero dispositivo di emergenza, che promette fino a 6 avvii di vetture e che si carica in soli 48 minuti utilizzando un buon alimentatore. Per me è un dispositivo indispensabile. Gli avvitatori di emergenza sono quei dispositivi che compri e non usi quasi mai e uno pensa che non valga la pena comprarli, ma quando una mattina scendete e la macchina non si avvia a causa del freddo o a causa della batteria vecchia vi assicuro che vi salva anche da brutte situazioni. Integrate in unico dispositivo l’aviatore, la torcia che serve sempre e una porta USB C che permette di caricare lo smartphone, significa avere un unico dispositivo che può salvare in diverse situazioni. Ottimi i materiali e l’attenzione ai dettagli, come tappi per i connettori e la sacca per il trasporto. Stra consigliato.
