NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 8.0L Gas and 6.0L Diesel Engines

As a mechanic, I’ve used a lot of jump starters and portable battery boosters. Most cheaper ones work at first, but fail when you actually need them. I’ve had the NOCO Boost GB70 2000A lithium jump starter since 2018, and it’s been extremely reliable. ✅ Strong starting power I mainly use this on power hungry luxury vehicles with high CCA batteries and large V8 engines, and it has no problem firing them up. It delivers consistent power and doesn’t struggle like lower-end units. ✅ Holds a charge for months This is the biggest reason I recommend it. I keep it in my truck year-round in Texas heat, and it will still jump start a car after sitting 6–12+ months. I’ve only charged it a handful of times, and never because it was too low to work. ✅ Easy and safe to use Reverse polarity protection and spark-proof clamps make it simple. You don’t have to second guess anything. Clamp it, power it on, and go. ✅ Portable and compact Small enough to keep in your truck without taking up space, but powerful enough to handle real situations. Easy to grab and use when needed. ✅ Versatile Works as a jump starter, battery booster, and also has USB ports for charging devices in an emergency. No built-in air compressor, but I’d rather have reliability than extra features. ✅ Cable length The clamps and cables are long enough to work comfortably without fighting for reach, which makes a difference when you’re in a tight spot. ✅ Solid build quality Feels durable and well-made. Not cheap or flimsy like a lot of other portable jump starters. ⚠️ Minor downside Charging speed is a bit slow, but that’s not a dealbreaker for something meant for emergencies. Bottom line: If you want a reliable jump starter, battery booster, or portable car jump starter that actually works when you need it, the NOCO GB70 is worth it. I’ll take reliability over extra features every time.

I keep this NOCO Boost GB70 in my vehicle for emergencies, and it has already paid for itself. After helping jump-start a few vehicles, including one with a completely drained battery, I’ve been very impressed with its performance and ease of use. The unit feels well-built and durable, and the included clamps make a secure connection. What I appreciate most is how straightforward it is to use. The safety features provide confidence, especially for people who don’t regularly work on vehicles and may be concerned about making a mistake. The 2000A rating proved more than capable for the gasoline engines I tested it on, and it started them much faster than I expected. The battery also seems to hold its charge well while stored in the vehicle, which is important for an emergency device that may sit unused for extended periods. Beyond jump-starting, the power bank functionality has been useful for charging phones and other small electronics during travel. It’s nice having a multi-purpose device instead of something that only serves one function. One minor drawback is that it’s larger and heavier than some smaller jump starters on the market, but that’s understandable given its higher power capability and larger battery capacity. Overall, this is one of those products you hope you never need but are glad to have when the situation arises. It performs as advertised, feels dependable, and provides excellent peace of mind for road trips, daily commuting, and emergency preparedness.

Works really well and built of really good quality. The battery life is great and it charges quickly. It extremely portable and not to big so storage is easy.

I've been a pro auto tech for long enough now that all the normal tools have been bought and paid for. You start looking for other things that you never really wanted to spend the money on, but always irritate you when the shop you're at doesn't have one, or the one they have sucks. I bought this because the place I was at, for a short time, reconditions and resells used cars. At any point in time we would have anywhere from 2500-5000 cars at the facility. It's a huge place, and a lot of dead batteries. On a daily basis I would need to jump start 4-10 cars. Cars ranging from tiny electric cars to diesel trucks. Out of the hundreds and hundreds of cars I've needed to jump, only one of them would the Genius not jump. And this was only due to an extreme discharge (1v), and no direct access to the battery terminals. Only tiny remote jump posts were accessible. The description claims that this will jump up to 20 cars on a single charge. I can vouch that this is an under estimate. I could use this all week, jumping 30 or more cars, before charging. I only plug it in when it reaches 25% according the to the LED indicators. On a very regular basis I would need to jump electric cars. Electric cars have a regular 12V battery for starting, and the motors run off a special battery. More often than not, the 12V battery, and the motor battery would be dead. So I would use the NOCO to start the car, then leave it connected in order to drive it to the shop (up to 1/3 mile from where cars parked). This little jump box will run an entire electric car with AC on full blast for several minutes and barely deplete its charge. However doing this multiple times throughout the day will deplete it more quickly. But if all you need to do is jump start, the charge lasts forever. Obviously you can use it in a similar way on a gasoline engine to run the car, when the alternator is bad. Only a few, very minor, points to mention. The cables are a little shorter than I'd like. This makes it more compact, but sometimes finnicky to get connected to a battery. The location, and ease of activation, of the light button make it entirely too easy to turn the light on. I found many times, I accidentally turned the light on without realizing it, and it stayed on for who knows how long until I noticed. Also it's a bit heavy to carry around. And this I only say because I had to carry it around in a backpack with other tools, and things I needed to do my job. For the normal person, the weight isn't an issue. It is by far smaller, and lighter, than the traditional jump box. And lastly, it takes a long time to fully charge. The better part of the day, if mostly depleted. So that's it. Those minor points are so minor, in no way should they deter you from buying this. I absolutely love this thing, and only hate that I waited so long to buy it. Update: Been using this now for almost 2 years. Still going strong. Working in a normal shop now, so not jump starting batteries every day. The charge still lasts forever. Also use to bench test starters. I now charge it probably once a month. It never goes dead, but if I see the charge is depleted when I use it, I will throw it on the charger. Still the best jump box I've ever used. Update: I bought this in March 2017. I'm now buying a second one. I want one for home now, so I'm getting the new one for work, and taking the old one home. I'll still love this jump box. Still working on cars, still jump starting cars on the daily. Now that this box is nearing 5 years old, the battery does need charged more often. Think of your old smart phone. But it's still kicking strong. The cables are still annoyingly short. I charge this every few weeks, and use it pretty much daily. The rest of my previous review still stands strong. The only difference now, is I have to charge it more often because the battery is so old. But still perfect for home use, and now I'll have a fresh new one for work.

The NOCO Boost GB70 2000A UltraSafe Jump Starter is an absolute powerhouse. It feels sturdy, rugged, and well built, and it is one of the best jump starters I have owned. Unlike cheaper jump starters that can feel flimsy or come with weak clamps, this one feels solid from top to bottom. The clamps are strong and have great grip, which makes a big difference when dealing with hard-to-reach battery terminals or older, worn battery clamps. The controls are intuitive, and the lights and other functions work very well. I have kept this charged for months, and every time I have needed it, it has done exactly what it was supposed to do. I have used it around the farm to jump a tractor, mower, car, and truck, and it has handled everything without issue. The built-in light has also been very useful when working on my tractor out in the field. The only downside is that it does not come with a hard case. It includes a storage bag, but a hard case would be much more convenient and protective, especially when trying to grab it quickly. Overall, this is a powerful, reliable, and high-quality jump starter that I am very pleased with.

I have had this jump starter for over three years now. I have found the following from experience: It stays charged for almost two years without having to plug it in. Above and beyond expectations. It starts the car several times without having to plug it in. Above and beyond expctations. It is a great jump starter, however, the reason for the 4 stars instead of five is, I finally hade to charge another device and the multiple device charging cord does not work. I tried to charge my ipad and it would not charge with the included cord but charges fine with my cord.

Best friend motorist can have, and it really works. I’ve helped many stranded motorists start their cars. Very same NOCO Jump Starter was carried by AAA when I needed help.

I bought this after my truck had been sitting long enough for the battery to become completely dead. I wasn't sure if a portable jump starter would be enough, but it fired the truck right up without any trouble. The unit was easy to use, the instructions were clear, and it gave me a lot more confidence than relying on someone else with jumper cables. It worked exactly as I hoped it would, and it's one of those things I'm glad to keep in the truck in case I ever need it again. It's small enough to fit right under the back seat of the truck for easy storage and has other great safety features like a light and ability to charge mobile devices if needed.

Excellent jump starter that works really well. I use it daily as a mechanic and it has been very reliable. It has plenty of power and starts vehicles without any trouble. The unit feels solid and well built, and the clamps are good quality. It’s also compact enough to keep in the vehicle. Overall a very dependable jump starter and well worth having.

Le NOCO Boost GB70 est tout simplement parfait. Très puissant, il démarre sans problème des véhicules avec batterie totalement à plat. Utilisation simple, sécurisée (pas d’erreur de polarité), et fabrication de grande qualité. Compact mais costaud, il se recharge vite et tient très bien la charge. Idéal à avoir dans la voiture ou le camping-car pour éviter les mauvaises surprises. Je recommande à 100 %

El producto se ve a simple vista que está fabricado con gran calidad. Todos los detalles lo denotan. El modelo nuevo es el que aparece en la web oficial pero hay una gama más antigua de arrancadores NOCO que llevan el nombre "Genius" y que ahora solo usan la gama de cargadores de batería NOCO. (Por eso se venden más baratos en EBay y hasta con su Estuche). El arrancador(Jump Starter) vino con su caja comercial y con blíster de plástico sellado cosa que se agradece evitando así sospecha de manipulación. A su vez el fabricante lo envía dentro de una caja de cartón y Amazon te lo puede enviar a su vez dentro de su caja. Llegó un día antes del plazo estipulado. Si quieres comprar el estuche original NOCO busca en la web oficial el que le corresponde al cargador de compres ya que hay varios modelos. Para este modelo de cargador el que le corresponde es el estuche GB014 y no ningún otro. Lo comento porque Amazon ha estado ofreciendo el modelo GB015 que no le corresponde. Si quieres comprar el Adaptador XGC4 de 56W para cargar en 2-3horas la batería es recomendable y según el manual es incluso necesario para la cobertura de la garantía ya que no se hacen responsables de uso de cargadores de terceros que además tardarán 7 horas en cargar al 100% la batería (cargadores de teléfono móvil por ejemplo). El adaptador viene con enchufes para todos los países y todos los voltajes incluido el que se usa en España(Europa). En el manual de usuario recomiendan hacer los arranques con la batería totalmente cargada dejando para el resto de usos como enchufar a infladores de ruedas o aspiradoras la energía restante. El manual viene impreso en castellano y muchos más idiomas pero en un tamaño ridículo que cuesta bastante leer así que usando el móvil tomé fotos y ampliando se lee mejor. El arrancador cumplió perfectamente su cometido en dos vehículos distintos de gasolina y diésel. Como las baterías de los dos coches estaban muertas tuve que usar un modo especifico que tiene dejando pulsado 3 segundos un botón y logró en los dos casos arrancar a la primera los vehículos. Como se hizo en una cochera con poca luz usé la luz de 400 lúmenes para ver bien donde estaba el polo positivo y el negativo de la batería a la hora de poner las pinzas. Lo bueno de este modelo frente a los inferiores de la gama es que este y los superiores traen toma de 12V y hasta15A para conectar aspiradores, infladores, etc... que en un viaje viene genial. Trae como la mayoría de las otras marcas toma para cargar el móvil pero no carga rápida. Muy contento con la compra y muy útil para los viajes.

Hatte mir das Teil doch ein wenig kleiner vorgestellt. Das ist ein richtig massiver Klopper! Die Zangen sind extremst massiv und vermitteln direkt einen wertigen Eindruck. Ein alter 2,8L Fiat Ducato Motor war jedenfalls kein Problem. Er startete sofort und die Akkuanzeige des Noco's zeigt immernoch voll an. Ein echtes Biest! Ok, vielleicht hätte ein oder zwei Nummern kleiner auch genügt ;-) , aber Sicher ist Sicher. Schade das man sich eine stabile Aufbewahrungsbox extra dazu bestellen muss. Das könnte bei dem Preis inkl. sein. Habe mich für die Originale entschieden, was im Nach hinein eine gute Entscheidung war.

軽量で使いやすく性能が良いのでとても重宝してます。
