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.

Flat battery = no problem. Works great on BMW
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.

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.

Best thing ever got… just having that option of boosting on a cold morning.
The NOCO GB40 Booster Pack is an outstanding portable jump starter that delivers reliable performance. Compact and lightweight design, it's easy to carry and store in your vehicle. Its 1000-amp peak current efficiently jump-starts dead batteries in cars, boats, and even small trucks. The build quality feels robust, with sturdy clamps and a durable casing. It also doubles as a power bank, featuring USB ports for charging devices, and has a bright LED flashlight with multiple modes, including emergency strobe. The user-friendly interface makes it simple to operate, even for beginners. One of its standout features is the spark-proof technology and reverse polarity protection, ensuring safety during use. The battery holds its charge well over time, providing peace of mind during emergencies. Overall, the NOCO GB40 is a highly reliable and versatile tool, perfect for anyone looking to be prepared on the road. Con: When wanting to charge bigger powered phones with USB C it thinks that it wants to charge the battery pack so drains the phone not charge…. You have to use the USB A to USB C cable and this fixes the issue when charging out from the booster pack.

Works great. Easy to use. Good to have in the boot.
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.

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

Super easy to use, super safe, started my car with it's dead battery immediately - can't imagine being without it especially in the winter when I sometimes only start my car once a month, Great product and great value too!

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.

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!!!
