If you get a good one it’s the best out there, keep your warranty handy just in case.
Good strong units, Will jump start anything with high power, recharges fast with the pd65w charger and well built.Only downside is we have had a few fail ( we use them quite often and have about 6 ) sadly 3 have had to be returned due to charging faults but hopefully this will be resolved by the company by better quality charging ports or what ever is responsible for them going wrong.When working they’re great.

POWERFUL IS AN UNDERSTATEMENT
GOODNESS ME, this thing packs a huge punch. Started my 4x4 that had a completely kaput battery in a matter of 2 seconds. Not cheap but its an awesome bit of kit

Impressive
Very impressed on a dead start diesal Land Rover, span it over and started without a problem.

Useless without a user manual!
Doesn't come with instructions! You may think, "well what could go wrong, it's a Jump starter", but there is no explanation how to use this device on keyless entry, start button cars, no explanation of using the "override button" etc or other "boost" functionality. In the 'what's in the box' photo on the advert for this item, there's an instruction book shown. It's not an instruction book, it's a 1cm thick, very small book you that you can't read where only 3 pages are in English, the rest is multi-languages for CE, and guarantee purposes. So you have to go online and read various articles written by NOCO. My 10 year old could write better and then there's disjointed videos that are meant to demonstrate how to use it. The listed spec and functionality sounds good, but it's pretty useless if there's no explanation of how to best use this device. I have a Masters in Electronics, this should be simple to use effectively, but you can quite easily misuse this unit and cause damage. I really wanted this unit to be good in real world usage, but without a clear explanation of how to use, its a waste of money. I expect more when you spend £350+ on the unit, extra leads, charger and a NOBO fitted case, you do expect a user manual or at wordt, legible intructions online! Returned for refund. I won't be buying anything fron NOCO again.

Perfect
Bought for work to use over winter for our fleet of vans. Definitely good quality and starts the batteries with no worries. Easy and quick to charge up. Wouldn’t be without it

The daddy of jump starters!
This is very powerful jump starter, it will start anything that moves.Previously I had a starter with half the charge capacity of the NOCO and I had trouble starting my diesel car engine. But with this one, it starts effortlessly every time.It takes a long time with a normal charger to fully charge it the first time, but after that it gets charged faster. It looses about 30%-40% of its charging power after a jump start so it needs to be charged again.I recommend charging it to full once every week to keep it in top condition and ready for action.I give it 4 stars because given how expensive it is a fast charger and a hard carry case should have been included in the price.

Noco jump starter
Delighted with my Noco battery jump starter. I purchased a different jump starter prior to purchasing the Noco model. The Noco is a real professional piece of equipment. You will not be disappointed with it.

C'est du lourd.
Ce n'est pas mon premier Booster NOCO. J'aime la puissance sans limite... Mais avouons que celà devient un peu encombrant. Belle qualité de fabrication. Mais NOCCO ne protège pas sufisement ses boutons. Donc dans un petit sac fournis, il est probable qu'il s'allume tout seul et finisse par vider ses batteries. Un petit morceau de carton suffit a se protéger du problème.

Útil y versátil
Compré este producto por recomendación, y he de decir que ha sido todo un acierto.En mi opción, tiene un tamaño y peso adecuados para ser transportado de forma frecuente, como es mi caso. Así como una estructura que lo hace manejable a la hora de ser utilizado.Por otro lado, considero importante destacar que la batería dura varios arranques. Lo que me facilita mi día a día, dado que lo utilizo en un ámbito profesional.Ademas, tiene varios extras como literna, que alumbra muy bien y puede resultar de utilidad en ambientes más oscuros o tenues. O bien puede utilizarse de powebank para cargar móviles, linternas o cualquier cosa que se conecte por USB.Sin duda ha sido una buena compra y repetiría.

It just works! Don't buy an El Cheapo "Gibberish Brand", buy this one! You WILL NOT be disappointed!
So, you're looking at this because you have a 1-ton truck? Dual batteries? And I'm guessing in the cold your engine simply just doesn't want to start, right? Or perhaps you've got a vehicle that loses battery charge after a couple days of being unused? Or perhaps you have a habit of accidentally leaving the dome light on all night? Or perhaps your battery just isn't up to snuff anymore and you just want to make sure it starts, regardless? And now you're looking at that price of $370 (at the time of this review) and thinking to yourself "There's got to be a cheaper one that will get the job done, right?" Short answer? Possibly. Shorter answer? DON'T!<] TLDR [>It absolutely works. It delivers the power it advertises. It's worth the money. If you want a boost pack that just works and you can afford it? Then just buy this one! You will NOT be disappointed! DO NOT buy the cheaper "Gibberish Brand" packs. If you do, you WILL be disappointed and they WILL leave you stranded.Yep. it really is that simple! My ONLY regret in buying this jump pack is that I didn't buy it sooner! I just couldn't justify the price tag... If I had known just how good it is, I'd have made room in the budget for it a lot sooner than I did!<] /TLDR [>I have a 1998 GMC K3500 with a dual battery setup. I do NOT have a block heater (yet). At zero degrees (F), it turns over but REFUSES to catch. After turning the engine over for roughly 10 seconds on a fresh full charge, it just quits. No go juice! And if you've done like I have by adding a manual override for your glow plugs because you upgraded them and know they can handle the extended burn time? It's still not enough. The batteries are just too small to be viable in the winter on the Canadian border where I am.[ Edit 3/19/26: I forgot to mention in this that I also upgraded my starter to a planetary gear high torque high speed starter, and it STILL doesn't like to catch in colder temps! ]Now that you have the backstory, I too was put off by the price. I watched a LOT of videos comparing various jump packs and every single one of them rated THIS pack, the NOCO Boost X GBX155 as the highest in every single list. I really had a tough time shelling out the cash for this, but now that I have it? I'll NEVER give it up!This thing is super easy to use. Charge it up when you get it. Believe it or not, for as heavy and bulky as this jump pack is, it charges FAST. From depleted to full charge in under 3 hours! That's AMAZING! If you have a dual battery diesel truck like me? You're going to be absolutely ASTONISHED at just how much power this thing packs. Its punch is nothing short of INCREDIBLE! When you hook it up to your battery, make sure you connect it to the battery that has the positive lead straight to the starter. While it'll work, connecting it to the accessory battery WILL cause a loss of power to the starter simply because of the cable run length from the accessory battery over to the primary start battery and then to the starter.Really, the only thing I can say I'm not too fond of is where they put the button to turn on the flashlight function. That darned thing is RIGHT where I grab it to pick it up and every time I pick it up I inadvertently press the flashlight button and let me tell you, it's pretty darned bright!This thing will also let you override the error condition on a FULLY depleted battery to allow you to jump the vehicle regardless of your battery voltage. Another really nice feature is the fact that it also has two USB-A ports to charge another device with, like your phone. The USB-C charging port can also be used to charge another USB-C device, too! The charging port goes two ways!The real reason you're looking at this specific jump pack though, is to find out if it lives up to its promises. I can tell you that yes, it absolutely does! Keep this in your vehicle and you'll end up being a hero to someone if they need a jump, too. No more need to carry long, heavy jumper cables if you've got this thing! You can rest easy if you have this jump pack. If you get into a spot of trouble because you left your headlights or marker lights or dome light on and ran your battery down while you were at the theater watching a movie or something? This will absolutely get you out of a jam.My truck is nearly 30 years old. I upgraded the starter to a planetary reduction gear starter. In the summer months, the dual batteries spin the engine decently with the specific starter I upgraded to. However, this jump pack? At ZERO degrees Fahrenheit, this jump pack cranks the engine over even faster than the dual batteries in the truck do!Because of where I am and my current vehicle situation, I'm having to jump the truck virtually every time I want to go somewhere. The truck's batteries just aren't enough and there's really no easy way to install bigger, more capable batteries under the hood. But, with this jump pack? I don't have to worry about whether the truck will start or not. It's virtually guaranteed it will. Without this jump pack, I'd be stuck most of the time in winter! You could call it peace of mind and you'd be accurate!If you're on the fence between this and a cheap one that's half the price or even a quarter of the price? Do yourself a favor! Forget the cheap ones, they don't stand a chance against this one. If you've got a family and you NEED your vehicle to just WORK regardless of having left that dome light on all night? You won't be disappointed if you have the NOCO Boost X GBX155. It's worth every penny!

Super Gerät, tut was er verspricht ,wenig Zubehör!!!
Habe mir was schönes gegönnt und bin wirklich soweit zufrieden !!!!.Außer das man sich separat für viel Geld noch irgendwelche Schnellladegeräte kaufen MUSS , wenn man noch weißt welche benötigt werden und Kompatibel sind ! Es wird nicht direkt darauf hingewiesen ( doch wird man hingewiesen , und zwar in Betriebsanleitung 🤦......sowas sollte gleich am anfang des Inserat,s beschrieben werden und gesagt , mindestens welches Ladegerät/e man dafür benötigt weil mit Handel üblichen Schnellladegeräten mit 25W brauch man ja gar nicht erst versuchen zu Laden , vorausgesetzt man hat zwei Tage Zeit dafür ............. Deswegen brauch man sich auch nicht wundern wenn die Kunden irgendwo anders solche Geräte Kaufen !Warum wohl ganz einfach MEHR ZUBEHÖR weil das Gerät schon Teuer genug ist .Es wäre das selbe wenn man sich ein KFZ kauft aber ohne Autoreifen die musste man sich dann vor Ort extragleich selber zusätzlich kaufen und vor Ort zusätzlich montieren damit man nach hause fahren kann !!!Der Verkäufer hat damit nichts zu tun und ist dafür nicht verantwortlich!!!! Sondern der Hersteller des Gerätes!!!!!Fals jemandem das weiter helfen sollte, ich habe mir zusätzlich für 35 Euro ein 65W marke ........!!!!!????? Schnellladegerät gekauft gleich mit mehreren Anschlüss möglichkeiten damit ich gleichzeitig auch andere Geräte laden kann , und es klappt wunderbar ,in ca. 3 Stunden ist der Noco GBX155 geladen.Neues Update !!!Ich bin persönlich bis jetzt wirklich zufrieden, habe viel Zeit gehabt den NOCO GBX155 zu Testen im Winter als auch im Sommer. Habe viele Fahrzeuge mit verschiedenen Autobatterien testen können und jedes mal erfolgreich die Fahrzeuge zum Leben erweckt, es funktioniert tadellos!!!Was ich bis jetzt festgestellt habe ist, das der NOCO GBX155 mittlerweile etwas länger benötigt um seine eigene Batterie 🔋 aufzuladen, am Anfang waren es ca. 3 Stunden bis Voll war , und jetzt braucht das 65W Schnellladegeräten etwas mehr Zeit und den NOCO aufzuladen. Es ist nichts Defekte und alles funktioniert wie am ersten Tag außer das er halt etwas länger die Batterie 🔋 Lädt bis es voll ist.Der NOCO GBX155 lag auch ein paar Wochen unbenutzt rum , habe den mit vollem Akku 🔋 bei Seite gepackt und als ich wieder einem Auto Starthilfe leisten musste dann war der NOCO GBX155 noch fast Voll .Fazit:Bin wirklich zufrieden!Ps.Das sind meine eigene Erfahrungen die ich persönlich mit dem NOCO GBX155 gemacht habe, und ich spreche nur für mich .Ich werde dafür nicht bezahlt oder sonstiges......Das Gerät habe ich auch selber gekauft und Bezahlt.Neues Update. 18.12.2023Soo , seit ein paar Tagen lässt mich meine Autobatterie im Stich die aber auch erst 11 Monate alt ist ....... hätte ich diesen NOCO GBX155 Buster nicht gehabt dann hätte ich schön schieben müssen 😅😅😅. Der NOCO GBX155 leistet seine Dienste bis jetzt gerade beim diesem Wetter Hervorragend! Keinerlei Probleme habe ich bis jetzt und Heute gehabt mit . Bring immer volle Leistung und startet mein waggen weiterhin zuverlässig.Neues Update 09.01.2024Der NOCO GBX 155 verdient definitiv 5 von 5 STERNEN gerade nach Heutigen Einsatz und -14 Grad den wir heute erleben haben !!!! , und gehört meiner Meinung nach zu dem 3 Besten den man im Moment auf dem Markt kriegen kann in seiner Preisklasse .Die ganze Zubehör die man auf diesem Video sieht , habe ich mir separat samt dem Koffer gekauft und ist leider NICHT im Lieferumfang enthalten!!! Beim Kauf des Noco,s erwirbt man nur das Gerät ohne alles aber mit der Stofftasche und ein USB-C Ladekabel ist dabei...Neues Update 11.02.2024Ich habe meinem guten Bekannten probeweise , der in der Abschleppdienst und Pannenhilfe 5 Mann Betrieb arbeitet , weil sein Booster , den man so aus dem Baumarkt kennt mit Tragegriffen , ziemlich groß den Dienst gestern mittag verweigert hat 🤦. Daraufhin als wir gestern telefoniert haben , habe ich Ihm für einen Arbeitstag mein Noco Boost GBX155 zu Verfügung gestellt und heute , als der Bekannte wieder meinen Noco GBX155 zurück gebracht hat , fragte mich mein Bekannter wo er sich so ein genialen Booster kaufen kann bzw sein Chef , er konnte bereits am dem Tag mehreren Fahrzeugen Starthilfe leisten und das nur mit einer Akkuladung . Er war quasi voll begeistert, klein handlich und lässt sich super und einfach bedienen mit ordentlich Power .
