Peace of Mind if your Battery Flat
Good item to have if your car battery goes flat - I have used twice with no problems & it started my car first time - Booster is Portable & Easy to Store in car - Quick & Easy to use - Easy to recharge via USB in car or indoors (while Booster comes with a USB charge lead, make sure it fits your charging ports - I have older car & had to use different USB lead - But it worked fine - Newer cars be ok) - Item delivered quickly & safely packaged - Highly Recommend if you'd like peace of mind in the event of a flat battery...!

It starts engines and it’s handy for camping
I’ve had this for a couple of years now so have had chance to use it now and again. It started my wife’s (1.4L petrol) engine immediately when the car battery went flat, and again the next day, without a recharge in between. I had less luck trying to start the 2L petrol on a Mazda I had SORNed for two years during the pandemic - but it turned out the battery on that was completely gone (along with the bodywork of the car, sadly). So it definitely works for jump starts but it’s not going to provide you with a miracle. I have also taken this battery on a few camping trips. Its solid, rugged design makes it much better suited to tent life than are those slim portable batteries designed for business trips. It also has a decent torch built-in, and you can never have too many of them when you’re camping. I’d estimate it can recharge a modern iPhone from almost dead to full approx three times along with occasional use as a torch - so it can supply a family for a night or two, provided the kids are round the campfire not hiding in the tents on their iPads. You probably wouldn’t want to use it heavily for camping, as like any battery it may degrade to the point where the primary car start function fails, but it’s a nice bonus. I’m pleased with this purchase. It’s a handy device to keep in the boot of your car at all times and has the bonus capability of providing battery power outdoors. Even if you have other cars around, it’s easier to use this than traditional jump leads: you don’t need to move two cars close enough for the jump leads to reach, or open two car bonnets.

Brilliant device but short cables
I bought this after quite a bit of research and I am very pleased with it. I used it to start my Hybrid Toyota Yaris and it provided the power instantly. Great. It also appears to be very strongly built and is easy to use. My only issue is that for Hybrid vehicle starting the positive connector attaches to a specific connector in a fuse box right at one side of the engine bay, and the negative attachment needs to go to the engine or other connected component. Even in the Yaris, the engine is very marginally too far away. I DID find a sopt (obvioulsy as it worked a treat) but the cables are designed o fit across a battery terminal and not across an engine bay. There aren't any NOCO extension leads either, so in my other car I guess I'll just have to extend the earth from the GB40 to the car via another charger cable clamped together. Hence 4 stars.

Reliable and powerful – highly recommended
I have been using this jump starter for several years now, and it has never let me down. It is powerful, reliable, and very easy to use. It starts the car quickly, even when the battery is completely flat. The build quality is excellent, and the charge lasts a long time. For the price, I haven’t found anything better. Definitely worth the money. Highly recommended!

Not great...
I bought this to replace a 6 year old, 500A, £45, no-name brand USB jump starter that was still starting the engine first time but only giving me 2 jump starts before needing to be charged, when it previously managed around 10 jumps. Decided to go for Noco as they are so highly rated but should have listened to the bad reviews.... I got the pack fully charged and tried it out on my 2.0L Diesel which regularly goes flat as something drains the battery and it fails to start if not driven every day- really should get it sorted! The Noco failed to start the car twice in normal mode so I turned on the Boost/override mode. This just about got it started but sounded like it struggled. (I waited about 30 seconds each time before starting the car) When I disconnected the charger I noticed it was almost flat with the red light showing, which was quite surprising as it says up to 20 uses between charges. I re-charged the Noco and tried again 2 days later. It took 2 attempts in normal mode this time and drained the pack to 50%. While the Noco did manage to start my car, I am disappointed with the performance and capacity. No idea how anybody could get 20 jump starts out of this and I really doubt the 1000A claims as my old 500A pack started the engine much faster and more reliably- while also lasting much longer! I did research the Noco jump starters before buying and decided on this GB40 pack over the GBX range as the GB(non X) ones are supposed to hold charge longer and give more jumps per charge, so I would definately not recommend the GBX either based off this experience. The GB40 has also been updated/refreshed but the Amazon listing has some conflicting info- I received the new version which includes a USB-C in/out port and a USB-A out port but no 12V lighter socket port or attachment. It also includes a thin fabric carry pouch (useless), a USB-C to C cable (no charging plug included) and the jump leads, which are short but were fine for me. The older version has 2 USB-A ports (1 in/out the other just output), a USB-A to A cable and a 12V lighter socket charger. The USB-C input is 5V 2.1A so no fast charger needed, pretty much any USB capable of charging will support this nowadays. Battery says it is 24Wh. If charging a phone from the USB port @ 5V 2.1A this would give 4800mAh but you would lose some of that as it wouldn't be 100% efficient so not enough to give a full charge on most modern phones. The jump leads seem high quality and have a strong grip. Connecting the leads to the power pack is not as easy as with other jump starters- have to push it quite hard to get it in, and it is not super clear which way round it is supposed to go in as the hole/plug is round-ish with no obvious markings- you have to look at the shape of the terminals inside the plug and socket and match them up (one is round, the other square). Unfortunately the jump starter I was previously using is no longer being sold so I will have to return the Noco and give another brand a try.

Väldigt robust, smidig och förtroendeingivande pryl. Testat 1 gång, bilen startade innan jag ens hunnit säga Engelbert Humperdinck.

Bu işi yapan cihazlar arasında kesinlikle en kalitelisi ,bu cihazlarda mühim olan kullanılan bataryanın kalitesi noco da kaliteli batarya kullanıldığını biliyorum. Defalarca aracımda kullandım ve hala şarjı yüzde yüz

Kann mir nicht vorstellen wie man das negativ bewerten kann, habe ich mir ursprünglich für mein Motorrad für unterwegs gekauft, jedoch erstmals für meinen PKW benutzt. Um gleich Mal ein paar Bewertungen in Frage zu stellen ich fahre einen Cupra 150 PS Diesel und starten hat sofort funktioniert. So einfach zu benutzen, nur an Plus und Minus Pol an der Batterie anklemmen einschalten und Auto starten. Sofort angesprungen und fast nichts an Leistung dabei verloren. Ausschalten anklemmen fertig. Klare Kaufempfehlung, klein, handlich praktisch!!!

Doskonały sprzęt. Mój akumulator był tak rozładowany, że nie mogłem otworzyć drzwi. Jednak z pomocą GB40 odpaliłem za pierwszym razem. Co ciekawe, poziom naładowania urządzenia nie zmienił się. Wszystkie lampki kontrolne, w tym zielona, świeciły się nadal. 👍

Propriétaire d'un Peugeot 5008, j'ai été confronté à une batterie un peu faible avec le mode "économie d'énergie" qui s'activait sans cesse. Le NOCO GB40 à réglé le problème en quelques secondes, seul bemol les cables sont assez courts . A voir au fils des ans sont efficacité déjà démarrer 3 véhicules sans rechargement Efficacité immédiate : Malgré le gabarit du véhicule et l'électronique embarquée très sensible de chez Peugeot, le booster lance le moteur instantanément sans aucun message d'erreur au tableau de bord. Petite précision : Sur le 5008, l'accès à la batterie peut être étroit. Les pinces NOCO sont fines mais très robustes, ce qui permet de bien mordre les cosses même quand l'espace est limité. Sérénité pour les vacances : Avec une voiture familiale souvent chargée avec les enfants, tomber en panne sur une aire d'autoroute est un cauchemar. Ce petit boîtier retire un gros stress. En résumé : Testé et approuvé C'est un outil de qualité semi-professionnelle qui rassure toute la famille. Je recommande à 100% . 💡 Le petit conseil en plus pour votre 5008 : Sur certains modèles de 5008, la borne négative (—) de la batterie est difficile d'accès car elle est reculée sous le pare-brise. N'oubliez pas que vous pouvez brancher la pince noire du NOCO sur une masse métallique du châssis (un gros boulon non peint sur le bloc moteur par exemple) cela à même fonctionné en rajoutant une rallonge car ma masse négative etait trop éloigné 👍
