NOCO Boost GB70 2000A UltraSafe Jump Starter, 12V Lithium Battery Booster | Spark-Proof & Reverse Polarity Protection, For Car, Truck, Motorcycle, SUV, Boat, ATV, RV, up to 8.0L Gas & 6.0L Diesel

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'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 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.

the saying you get what you pay for are right, expensive but good well manufactured product, works great, pretty heavy but feels robust. Have used it a few times to help stranded people so been a good addition to have in your truck at all times, so good purchase another for sons birthday.

I received this item as a birthday present and as a congratulations gift for my shiny new Jeep Wrangler. It saved me from very expensive dealer repairs and towing expenses. Far more than the cost of this excellent product. Worth every penny and far superior to the Chinese no name jump starters sold in stores under many names. The crude copy cat designs frequently don't have enough current to do the job, and don't have the safety shutoff override button or the 12VDC output port. Vastly inferior products are everywhere, and they often lead to stranded vehicles. I purchased a fully equipped JL Rubicon four door model that was traded in at the end of a lease, thinking that I would get a reliable vehicle without the problems of the older JK version of the Wrangler. Initially there were improvements everywhere, but within a month the dual 12V battery problems left both batteries completely dead. I learned that for all Chrysler vehicles with Auto Stop Start and dual 12 V batteries, this failure mode happens to 100% of the vehicles that reach two or three years of age. That is, EVERY ONE of these vehicles will end up bricked- dead - on a morning when you need to go somewhere. This NOCO GB70 made the starter motor spin faster than I have ever heard as soon as I pushed the START button. The engine started immediately. During the days needed between the battery failure and the day I could go to an auto parts store to buy the larger Absorbed Glass Mat (AGM) type of battery that the Rubicon requires, I used the NOCO GB 70 to start the engine every morning even though the original battery was so dead that most jump starter devices will refuse to activate their outputs. If I had one of those, it would have failed to start the engine. I am highly impressed with the accessories. The ability to fast charge from a 14Volt DC power outlet (in the old days, for cigarette lighters) while in a vehicle is a great feature. The USB input and output is great. Best of all, the cable and connector setup allows the device to be used as a stand alone 12VDC power source for any equipment that can connect to the standard automotive 12 VDC power outlet in a dashboard. Much smaller and lighter than trying to do this with a lead acid battery. This is one of the best automotive self rescue devices ever made. Buy one for yourself and everyone in your family that owns a car. Keep them charged and never worry about starting problems.

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.

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 %

If you are trying to decide whether to spend this amount of money and wondering if it actually works, then I can confirm it does. It is a bit expensive but still half the cost of a battery for my vehicle, Chrysler Grand Voyager 2.8 CRD Diesel. It is so easy and quick to connect, it is so compact that I thought it would never work, I was wrong. As it says in the video there is no need to wait, just attach it to the battery and switch it on, then start the car, it is that quick. Charging in the car takes very little time at all. It does look good and I cannot fault it at all. I opted for the GB70 as it has 2000A power as my engine is quite old, 20 years, and 2,8l diesel, and it cranks it better than the actual battery. I highly recommend this jump starter power pack, with this in your glove box you never have to worry about your battery going flat in the forthcoming cold weather.

軽量で使いやすく性能が良いのでとても重宝してます。

Dopo averlo testato a dovere posso recensire l’Avviatore d’emergenza Noco GB70 da ben 2000A di spunto La confezione si presenta curata con un ottimo livello imballo a protezione di possibili urti, all’interno troviamo il Noco GB70, sacchetto proteggi polvere, cavo usb di ricarica, connettore accendisigari con porta usb, connettore da accendisigari a cavo 12v oltre logicamente a manuale d’uso in tutte li lingue. sarebbe stata molto apprezzata la valigia di trasporto semirigida inclusa che è disponibile dal produttore come optional La prima carica con cavetto usb collegato a un qualsiasi caricatore da 5v (quello classico del telefono va benissimo) ha richiesto circa 8h (la casa dichiara la capacità di mantenere la piena carica per circa un anno) Questo dipende dagli ampere del caricabatterie che usiamo con uno da 0,5A occorrono 28h mentre con uno da 2A bastano 7h oppure 3h a 12v 36w Una volta caricato durante le varie prove eseguite vengono caricati tramite la usb diversi dispositivi da cellulari a computer portatili anche con una discreta velocità, nessun conflitto riscontrato con dispositivi e o cavi ricarica Apple,inoltre la torcia e veramente potente e impostabile su diverse modalità di potenza compreso lampeggio SOS, tornando sulla funzione principe del dispositivo ovvero la capacità di avviare il motore con batteria ko nello specifico del GB70 motori benzina fino a 8000cc e per disel 6000cc come limite è stato impeccabile in grado di avviare un l200 (2.5l gasolio) con batteria scarica semplicemente collegando i morsetti rispettandone la polarità (da apprezzare che i cavi sono inglobati nel dispositivo a differenza delle versioni più piccole dov’è vanno collegati ) accendendo il dispositivo lui eseguirà controlli di polarità e corto circuito quindi non è possibile sbagliare se i cavi sono posizionati male o peggio in corto vi darà errore impedendovi di provocare danni, mentre se è tutto ok inizieranno a lampeggiare i led relativi alla carica della batteria a quel punto girando la chiave il motore va in moto al primo tentativo (motore freddo) non contento ho simulato la batteria completamente scarica sotto i 2v staccando il polo negativo impedendo al Noco di riconoscere la batteria ma tenendo premuto il tasto con il punto interrogativo si attiva la modalità forzata collegando il polo positivo alla batteria e il negativo al telaio stesso della macchina tutta la potenza viene rilasciata (disattivando le sicurezze quindi prestare la massima attenzione) girando la chiave il motore va in moto al primo colpo sono stati avviati anche un Iveco daily 2.3 Dobló e fiorino tutte con le stesse modalità è stesso risultato è incredibilmente lo stato di carica è ancora al massimo In conclusione non posso che essere soddisfatto del prodotto, certo non è proprio economico ma si percepisce la qualità appena preso in mano e la qualità si sa, si paga

Funktioniert für Autos als Starthilfe 4-5 x mit einer Aufladung. In der Werkstatt hatte man uns das Gerät empfohlen, lädt auch das Mobiltelefon auf, also prima für unterwegs, auch um mal anderen zu helfen.
