Boost GB40: 1000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 6.0L Gas and 3.0L Diesel Engines

This is a good little jump pack. Handy to have and will jump a car several times. I like the size, the portability, and the ease of charging. I carry in my work vehicle normally, as we are constantly on the go and this has been handy several times. I like that I can jump to get me going and then carry around to be sure I don't get stranded. Simple to use. Way easier than jumping from another car.

This battery jumper works great!!! I had a battery that was brand new but it started giving me trouble. I charged up this jumper and decided to take it with me when I took my pup to in for a check up at the vet. Afterward, my truck would not start. This jumper worked effortlessly and got my truck going on the 1st try. Keep in mind that I am old and female and I was able to this, by myself, quite easily!! I was so glad I had gotten this. I took my truck back where I got my battery from and they put a new battery in my truck that was the correct required size for my truck. I bought a hard carry case for this jump starter and I take it with me everywhere. It's small, light weight, very easy to use, and it may come in handy again someday.

This product truly makes jumper cables obsolete. I purchased this 1 1/2 years ago, charged it, and then stored it in my Honda Accord's trunk. It was not until yesterday, 1 1/2 years later, that I needed it to try to start my car's depleted battery (due the cabin light having been left on overnight). I could see that the NOCO Boost still retained 50% of its charge despite having sat in my trunk for 1 1/2 years. I firmly connected it to my car's battery and immediately my car's dashboard came to life. I waited less than one minute before twisting the ignition key, and on the 2nd attempt (within only seconds of my 1st attempt) - my engine started up. In the past, I have hated to beg strangers to give me a jump, even though I have always carried jumper cables. And AAA has been a nightmare, because whenever have I needed a jump in the past (before buyng the NOCO Boost) - I have had to wait close to 3 hours for AAA to come to me. Then I found out about the NOCO Boost from someone working for AAA who used it to jump an old car of mine. I purchased one immediately. This product is so small, so convenient to use, and mine has proved itself to be so reliable, that I consider it to be a MUST HAVE ! It is sad that a couple reviewers have stated that their product failed to work for them. But with an overall composite star rating of 4.6, clearly almost everyone experiences their product to be reliable. This product should be charged before storing it away. I do not remember whether mine came with a charge.

When I borrowed an old never used car my dad gave me one of these to jump the car, it never failed me. I have a sports car I only use and got tired of jumping it with my other car. I went straight for one of these but wasn’t sure if the 1000A would start a 3.5 v6 as even jumping it with my car would take awhile. When it got delivered, it had 3 bars of battery and started the car up no problem at all. It’s a little expensive compared to some of the cheaper options but with this one I know I can rely on it and won’t be stranded. Well worth the price. It’s the size of my for arm, with simple design and bright led lighting, it’s rugged so you know it could handle abuse. Usb-c charging and provided with cable. I seen someone give a 1 star because of this. It’s 2026 what do you expect? Supports fast charging. Nicely packaged and come’s with a nice little bag to place everything in. Only thing I don’t like is it uses usb outlet to charge things but I didn’t buy this to charge a phone so don’t really care.

This worked perfectly for jump starting my hybrid which was dead. I took off one star because I didn’t find the directions clear and had to watch a few you tube videos to figure it out. After that it was easy as pie! Great device! I’m thinking of getting their trickle charger for the next time the car has to sit and not be used for a while. Great product!

I bought this jump box for my daughter to keep in her car for emergencies. Little did I know she would use it getting off late from work in u def a week. It was simple for her to use and she is not mechanically inclined either. Started her car in seconds. It works well, is in a nice bag to keep everything together in your emergency car kit. Charges your devices and has different lightning functions for other tasks.

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

Hoy lo he utilizado por primera vez, después de la compra y primera carga hace cuestión de 2 semanas, funciona de maravilla y arrancar el coche a la primera y en menos de 2-3 segundos batería sin energía nula, ni el centralizado funcionaba. Lo recomiendo tanto como usuario de calle como profesional.

Super sprzet

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!!!

​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 👍
