Excellent !
DĂ©marre un Diesel batterie totalement Ă plat tel que le CLK 270 CDI 170 cv 6,5 L comme un coucou Suisse ...en un tour de clef. Le plus compliquĂ© est de trouver une bonne prise de terre. 4 dĂ©marrages dans le mois sans soucis. PrĂ©voir une nouvelle charge complĂšte du Booster aprĂšs le 5Ăšme raccordement ou avant par prĂ©caution si vous avez un impĂ©ratif (mieux ne vaut pas forcer votre chance en misant sur un 5Ăšme dĂ©marrage). LâEVA Case du GB 150 convient, bien que le GBX155 soit trĂšs lĂ©gĂšrement plus petit (1 cm de moins en longueur, idem en largeur, mĂȘme taille en hauteur Ă 0,05 cm prĂšs [donnĂ©es constructeurs]). MalgrĂ© cela, pour les maniaques comme moi, je ne le recommande pas car, mĂȘme sâil est de bonne facture et de finition soignĂ©e, il ne sâadapte pas totalement (les cĂąbles des pinces en position de rangement forcent le passage de la niche du Booster et trouve une issue en hauteur de lâEVA Case ce qui est incomprĂ©hensible puisque le GBX155 est plus petit que le GB 150. Jâai mĂȘme essayĂ© de laisser les cĂąbles de chaque cĂŽtĂ© plutĂŽt que de faire le tour du Booster comme câest le cas en position de rangement ...câest pire). Ajoutez à ça une rĂ©partition du poids du GBX155 pas au top, et je vous le dĂ©conseille fortement. Comprenez que poignĂ©e en main lâEVA Case bascule totalement dâun cĂŽtĂ© (dĂ©sagrĂ©able lors des manipulations). Amazon le mets parmi les produits frĂ©quemment achetĂ©s avec le GBX155. Il faudrait peut-ĂȘtre comptabiliser les retours produits, car Ă mon sens ce nâest pas trĂšs pertinent et trompeur compte tenu du fait que ce produit nâest pas totalement adaptĂ©. Câest encore pire avec le chargeur XGC4 qui nâest pas du tout compatible et pour cause, la technologie X est dĂ©jĂ dans le GB X 155 (cette technologie dĂ©passe dâailleurs le seul fait de la charge rapide et concerne entre autre la puissance rendue en ampĂšres) mais la description nâest pas claire et, bien quâayant cherchĂ© avant achat, je nâai rien trouvĂ© qui confirmait ou qui indiquait une incompatibilitĂ© des 2 produits. De plus, comme je le dis plus haut, les produits sont frĂ©quemment achetĂ©s ensemble. RĂ©sultat : 1 retour Ă lâenvoyeur et un remboursement Ă attendre. Pour une charge rapide en 2,7H vous devrez donc chercher (ou plutĂŽt trouver) un chargeur rapide USB A adĂ©quate (perso, je cherche encore). Dommage que NoCo ne prenne pas la peine de prĂ©ciser les spĂ©cificitĂ©s du chargeur nĂ©cessaire ou de recommander une rĂ©fĂ©rence Ă dĂ©faut de la produire (lâentrĂ©e en charge du Booster est donnĂ©e pour 60 Watts... la plupart des chargeurs USB A sont soit au dessous, soit Ă 65 Watts et plus. Je penses que 65 Watts est donc la meilleure option). Le rĂ©sultat obtenu avec une prise Type C vers USB A comme celle (Ă lâĂ©poque) fournie avec un iPhone (soit 18 Watts il me semble, voir peut-ĂȘtre 12W ou encore moins ...5W ??!) donne un rĂ©sultat moins performant que le temps de charge maximale indiquĂ© par le fabricant (comptez 72H pour une charge de 0 Ă 100%). NoCo doit probablement sâappuyer sur les rĂ©sultats obtenus avec un chargeur entre 20 et 40 Watts pour garantir une pleine charge au terme de 16H (...quand mĂȘme). Quant Ă savoir si un chargeur de 90 Watts ou plus peut permettre une pleine charge en moins de 2,7H... ??? Quid ? Si quelquâun Ă des chiffres, je suis Ă lâĂ©coute. Le plus gros dĂ©faut de ce produit reste la taille des cĂąbles USB C de chargement fournis ...ils sont ridiculement petits (particuliĂšrement le cĂąble USB C vers USB A. Cela est moins dĂ©rangeant avec le cĂąble USB C vers Prise Allume Cigare). Mieux vaut donc trouver une prise prĂšs du sol ou proche dâune table ...sinon vous devrez rester debout durant (minimum) 16H, le chargeur dans les bras ! đđ MĂ J du commentaire de DĂ©cembre 2021 : Jâai fait lâacquisition dâun chargeur de marque dâune puissance de 65W (et de technologie GAN II) et dâun cĂąble de 100W Ă puce (IC E-Marker ?) de la mĂȘme marque et lĂ câest juste... une DINGUERIE ! Ăa marche du feu de Dieu ! Comptez entre 30 et 35 mn par voyant soit pour 1 quart de charge (25% de la charge totale en une demi-heure ...tout le monde suit ?) soit de 2H Ă 2H20 max pour une pleine charge de 0 Ă 100 %, mieux que les donnĂ©es constructeurs qui garantissent une pleine charge en 2,7H soit 2H42. Reste Ă savoir ce que cela pourrait donner avec un chargeur de mĂȘme technologie (GAN II) mais dâune puissance de 90W ...ou mĂȘme de 100W ???!!? đ€© DerniĂšre MĂ J du commentaire : La charge rapide ne donne pas les mĂȘmes rĂ©sultats quâune charge lente. Avec la charge ultra lente en 72H jâai des rĂ©sultats incroyables. Avec les charges standard et ultra rapide, le produit est simplement trĂšs dĂ©cevant !

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 protÚge 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 problÚme.

Ătil y versĂĄtil
ComprĂ© este producto por recomendaciĂłn, y he de decir que ha sido todo un acierto. En mi opciĂłn, tiene un tamaño y peso adecuados para ser transportado de forma frecuente, como es mi caso. AsĂ como una estructura que lo hace manejable a la hora de ser utilizado. Por otro lado, considero importante destacar que la baterĂa dura varios arranques. Lo que me facilita mi dĂa a dĂa, dado que lo utilizo en un ĂĄmbito profesional. Ademas, tiene varios extras como literna, que alumbra muy bien y puede resultar de utilidad en ambientes mĂĄs oscuros o tenues. O bien puede utilizarse de powebank para cargar mĂłviles, linternas o cualquier cosa que se conecte por USB. Sin duda ha sido una buena compra y repetirĂa.

Very poor . Fails to start most vehicles when other units work
Very bad, only starts half the cars, my 4 year old 3000amp works better. Has no volt meter either showing what voltage is in battery your connected too

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!
