Boost GB40: 1000A UltraSafe Jump Starter Power Pack – 12V Car Battery Booster, Portable Power Bank & Jump Leads - For 6.0L Petrol and 3.0L Diesel Engines

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...!

Very impressive. I bought this to replace another similar device that I previously purchased that just didn't have the power to start my 2 litre BMW car on a cold day. This product was the real deal. All you do is connect it to your car battery terminals and just start your car. My battery was draining flat on a daily basis but this product started my car in seconds every single time. It's well made and so easy to use and best of all, it can start an completely flat battery. Watch some of the videos on YouTube about this item and the tests it has been put through for further proof of just how good it is. Best tip is to use it when it is 100% charged.

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.

Firstly I have been trying to find out how long the main booster cable are - they reach 23 inches (just) from tip of red croc clamp to tip of back croc clamp, by pulling them straight, only just ok for a Kuga PHEV under bonnet plus and minus posts. Secondly I didn’t realise that the connecting charge cable is USB C at both ends so you’ll need a USB C charger ( Anker £7.98) or a USB A to USB C connecting cable as most places I’ve stayed only have A outlets so C to C will be useless. Other than that, it appears well made and comes with a soft bag to keep it in, make sure you download the operating manual from Amazon as it’s not included in the box

I have to say that it worked great. I was away for several weeks. The battery still had power but not enough to start my 2020 car with original battery. Not the first time this happened. I called AA but my coverage expired. It would cost £150 for a call out. Now I have a device that I can carry in the boot, clamp a few bits and be on my way if it happens again. It's not rocket science. Just look at the car manual and the device instructions.

Don't normally leave reviews but this product deserves one. Bought the NOCO Boost GB40 for my son for Xmas. However my car battery declined over that Xmas period. I used this to start my 1.4ltr Astra 6 times. My car started each time as if it had a brand new battery. The NOCO charge indicater didn't move, as if it had never been used. This product is unbelievable. Buying another for myself to leave in the boot. Bye bye jump leads the future is here.

So after using what was possibly a faulty OBD that coincidentally lowered the battery voltage within a few minutes of use on my 2016 Ford Mondeo 2.0l diesel to the point I had to get the AA out as my car wouldn't start. The AA guy gave my battery a health check , checked the charging system of the car and said it was all working fine but the battery volts were too low at 10v to start the car. He connected a booster pack and the car started with a single push of the starter button. He advised I drive the car for a good 40 minutes to charge the battery back up. Unfortunately, I didn't do that and although the car started fine the next day , I did do several short journeys and then didn't drive the car over the weekend. Went to go to work this morning and "click", the car wouldn't start with the battery light on the dash lighting up. Luckily, I had purchased this booster on Friday night from Amazon, it came Saturday, I charged it via one of the usb ports on our kitchen sockets until fully charged, about 3 hours. Got the opportunity to use it this morning, plugged on the jumper cable to the booster and the leads onto the battery, jumped into the drivers seat and pushed the starter button, car started instantly with no problem. I've driven about 200 miles today with one of the legs being around an hour and a quarter so hopefully the car battery has fully charged. If I need to use this regularly I think I'm going to have to buy a new car battery, but, we will see how it goes. As for this little box of tricks, very impressed, saved me calling out the AA again and having to hang around waiting, also saved me from cancelling a call to my first and second customer. Easy to use, saved me a load of hassle, very pleased with this. Thank you.

Helt suverän att ha med sig i bilen eller mc tar lite plats och en räddare i nöden

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

ممتاز وفعال في اداء المهمام تم استخدامها لاكثر من مره لي ولجيراني ابد ركبها على الأصابع وأتركها لمدة 10 ثواني وشغل 👍

​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 👍
