Boost X GBX55: 1750A UltraSafe Jump Starter Power Pack – 12V Car Battery Booster, Portable Power Bank & Jump Leads - For 7.5L Petrol and 5.0L Diesel Engines

I bought this three weeks ago after realizing that traditional jump leads are an absolute nightmare and often risky to use on modern, sensitive electronics. My Renault Grand Scenic relies entirely on a keyless start system, and trying to jump-start it from another car's battery can easily fry the vehicle's computer or cause massive voltage spikes. The NOCO Boost X GBX55 completely eliminates that anxiety. It is incredibly compact, yet it started my Grand Scenic on the very first try without hesitating. Because it regulates its own voltage, it is completely safe for the car's delicate electronic ECUs. The spark-proof design and reverse polarity protection mean you literally cannot connect it up wrong, giving you total peace of mind in the dark. I also love the USB-C fast charging feature; great for charging your phone. It feels rugged, high-quality, and fits easily into the glovebox. I’ve only owned it for three weeks, but I genuinely won't go on a road trip without it now. Highly recommend!

Bought this booster pack purely on personal recommendation from a couple of fellow Motorhome owners as there are so many compact booster packs about its very confusing. My van is left for quite some time during the Winter mths and the vehicle battery is obviously subject to a bit of natural cold weather drain and also parasitic drain from the alarm and other security features. This has been invaluable for the few times I've used it and well worth the money. Its really easy to use with plenty of power, easily starting my 2.2ltr diesel motorhome and a few times on my spare car which we use to tow behind the MoHo. I've charged up it once upon delivery and so far made around half a dozen starts on this single charge. It's still has 50% power capacity so I'm very pleased with that. It has a very useful built in bright led light which can be set as a flashing light or S.O.S. Flash. The unit can also be used as a power station for recharging lap tops, mobile phones and tablets. A very worth while addition. My experience so far would rate it as 5 stars all round and I too can highly recommend this product. It comes well packaged in its box within a box so to speak and it also has a carry bag. It is compact enough to fit into most glove boxes or carry under a seat. Brilliant bit of kit!

We have a 2015 Mitsubishi Shogun 3.2 diesel which my wife loves. My children also have cars and always seem to park them in inaccessible locations before killing the battery expecting the jump leads to preform witchcraft. The thing is with short journeys and loads of electronic equipment in/on the car it kills the battery. My wife and young son have been stranded a couple of times waIting for me or the RAC to get to them due to a dead battery (1yr old yuassa with 5yr warranty, nothing up with it) I've been looking to get something to keep in the car just in case, this NOCO Boost X GBX55 is ideal as its good for all our car engine sizes. I ordered it on amazon (the cheapest place by miles) and expected it to be as good as all the reviews suggest. We'll it was delivered rapidly and well packaged (not excessive) from the minute I opened the box I knew I was in safe hands. Its very well made and of great quality. I have put it on charge and will see how well it performs when my wife or one of the kids next get stranded. I have no doubt it will do its job, some are moaning and I can only assume they have either not read the manual or have other issues. ....Update..... It works, a flat battery on a cold morning prompted a phone call to me from the wife in a panic she was going to miss a hospital appointment. I asked her to look in the boot for the noco booster which has been there forgotten about since we purchased it. Still fully charged might I add.... After a couple of minutes talking through what to do the car was running...Happy wife who said its one of the best things we've purchased. on the evening I just topped up the charge and its back in the boot if needed again. It's an expensive initial outlay but it's worth it in my opinion 10/10 for the noco GBX55, shame there is no hard case available....

I used a Suaoki P4 before and was very disappointed that it never worked to successful jump start my (smaller) van. I now have a Transit Mk8 2018 2.0L & as a solo female who is building my van and plans to live in it soon, I wanted something reliable that could jump start me on the inevitable occasion that the battery got flattened (it always eventually does... no matter how careful you are for the most part) I did some research and settled on this one - I know it's somewhat overkill and I can't recall exactly what pushed me towards this model. Regardless I appreciate the neat design with the place for the clips. to clamp on for tidy storage. It was ~£185 at time of purchase and whilst not cheap I think it is well worth it. I have only charged this up once and then it has been tucked in my glovebox for a year until today. I'm not sure what happened but somehow my battery ended up completely flat with the engine not turning over at all. Thought I'd try this, thinking it probably wouldn't work... but it started instantly! Amazing! The battery not only has been stored for a year, but has contended with sub zero and over 40°C heat in the van at times. I can highly recommend. This was such a quick and faff-free solution that got me up and running quickly and without help. In a difference situation it could be a lifesaver. I think the GBX45 will be sufficient for most vans however & will save £50 or so.

Functionally great unit, almost idiot proof. Despite it's tiny size it has started my old Land Rover 8 times before it dropped one battery level. Charged it overnight using a normal usb wall socket no problem at all (and you can charge it from the car when you've started it). Only real gripe is that the plastic protecting the copper clips has already broken on two corners. It doesn't effect the function or safety but it doesn't bode well for something less than a week old. Overall though a great bit of kit

I bought this product early 2024 and have only use the charger twice since. it is a very good product when charged. however after my second use, the battery went flat out. I tried charging using the charger and I had no luck because it did not charge. I bought other charger recommended for the product and I had no luck. I contacted NOCO via email as I had no other way of charging to see if they have a UK office I can send the product to for checking as nothing seem to charge my charger, I had no response. I am no impressed that a product I bought and cannot charge is with me and out of use. and I am extremely disappointed with NOCO. I would not recommend this product. on the other hand, I made have been sold a faulty product. I had to rate 1 star to submit otherwise its -0 star.

Saved me a few times. Easy to use. Easy to store. Powerful.

What a great product! got a chinese one at first.. dont bother never worked sent that back and got this one. out of the the box it started my old Landrover first time, very impressed for something so small! I also have one of the chargers as well also very good

Der NOCO Boost X GBX55 ist mittlerweile mein ständiger Begleiter im Auto – einfach, weil er mir schon zweimal den Tag gerettet hat. Mit satten 1750A Spitzenstrom und der Fähigkeit, bis zu 7,5-Liter Benziner und 5,0-Liter Diesel zu starten, ist er ein echter Lebensretter für Fahrer, die nicht auf den Pannendienst warten wollen. 📦 Erster Eindruck & Verarbeitung Beim Auspacken merkt man sofort: Das Teil ist robust gebaut. Das Gehäuse ist gummiert, wirkt stoßfest und liegt dank griffiger Struktur gut in der Hand. Die Anschlüsse sind mit Schutzkappen versehen, sodass kein Dreck oder Feuchtigkeit eindringen kann – perfekt für den Kofferraum. Das Set enthält: ✅ Starthilfekabel mit soliden Klemmen ✅ USB-C Kabel zum Laden ✅ Klare, bebilderte Bedienungsanleitung 🔌 Funktionen & Einsatz Der GBX55 ist nicht nur ein Starthilfe-Booster, sondern auch eine Powerbank mit USB-A und USB-C-Anschluss. So kann man auch mal schnell das Smartphone, Tablet oder sogar eine kleine Kühlbox aufladen. 📱💡 Starthilfe in der Praxis: Ich habe damit einen 3,0-L Diesel bei -4°C gestartet – Problemlos, innerhalb von Sekunden. Selbst bei einer komplett leeren Batterie musste ich nur kurz warten, bis die Elektronik geladen hatte, und schon lief der Motor. 💪 Sicherheitsfeatures: Funken- und Verpolungsschutz ✅ Status-LEDs zur Anzeige der Ladebereitschaft ✅ Boost-Funktion für besonders leere Batterien ✅ 📊 Pro & Contra aus meinem Test Vorteile: ✅ Extrem starke Leistung – startet auch große Motoren sicher ✅ Kompakte Größe für die Leistungsklasse ✅ USB-C mit Schnellladefunktion für den Booster selbst ✅ Sehr sichere Bedienung, auch für Laien Nachteile: ❌ Relativ hoher Preis 💰 ❌ Kein Netzladegerät im Lieferumfang – nur USB-C Kabel ❌ Bei häufiger Nutzung als Powerbank entlädt sich der Akku natürlich schneller, und man muss daran denken, ihn wieder vollzuladen 🏁 Fazit Der NOCO Boost X GBX55 ist für mich ein Muss für jeden, der auf Nummer sicher gehen will – egal, ob im Alltag, auf langen Reisen oder beim Camping. Er ist zuverlässig, kraftvoll und einfach zu bedienen. Der Preis ist nicht ohne, aber wenn man bedenkt, wie oft er den Pannendienst ersetzen kann, lohnt sich die Investition. ⭐ 5 von 5 Sternen – Kompakt, stark und sicher. Nur ein Netzladegerät im Set hätte es perfekt gemacht. 🚗🔋⚡

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.)
