Best car battery jumper I have come across! One on button, and immediate jump power without any problems at all. Remarkable power to start sedan or large trucks like Toyota Tundra super max. I bought a second unit for my son. The size is small and extremely easy to connect without long extension or need for a second vehicle like regular jumper cables. I can jump start at least 3 vehicle before needing to charge. Has an LED for night use. Very compacted size with a nice cloth bag for storage. Can be charged via USB, 110v or 12v plug in. All included. Definitely worth the money for its reliability, quality and charge hold. Highly recommended! You can also use it to charge other electronics such as phones or tablets! Read more

Product works great. Love that it was fully charged when I received it because I needed it in Such short notice. It’s small and compact enough that it barely takes up any room. The light on the battery is great because it has several different settings. This product is easy to use and not overly complicated. Read more

Bought the GB70 over the GB40 because bigger is better? It was $100 more expensive and for the average/casual user it’s probably not worth it. Had a dead battery on our 2014 Lexus IS 250, which we haven’t been driving lately. Had to use the override feature on the NOCO, because the battery was really dead, but it started right up. Would definitely recommend. Much more convenient than using jumper cables and a donor vehicle. Be prepared for the car alarm/horn to go off when using the override feature!! The instruction manual that comes with it is pretty much useless; it’s in micro print. Seriously, you’ll need a magnifying glass to read the thing. I ended up finding the manual online and printing out the 3 pages I needed for future reference. As a quick start guide I found some things on YouTube. To charge the GB70, a short USB C cord is provided, but you need to provide your own charging block/wall plug for the cord. It also comes with a cord and adapter so you can charge it, or keep it charged, in your car. It has a built in flashlight with several brightness settings and a USB A “Out” port so you can use it to charge various devices (you’ll need to provide the USB A cord, however). I really like this product. Just need to keep it charged because when you need it, you need it. I’ll also be bringing it along on all future road trips. Read more

Cannot beat Novo jump boxes. This is my second to have in vehicles around the farm. This will jump most of the equipment on my farm. I have the Big 4000+ amp jump box for my larger equipment (10-12 liter diesel engines). This 2000A GB70 is a smaller form factor and is great to keep under the backseat of my pickup or trunk of my car. I wouldn’t go anywhere without one. With the NOCO jump boxes you can wave goodbye to having what always seems to turn into a tangle of jumper cables in your trunk or bed of the pickup. The NOCO jump boxes are easy to use, they have polarity protection, they charge very quickly from USB-C, from a 12 volt power outlet in you vehicle, or you can purchase a quick charge wall adapter from here on Amazon. On top of everything else you can charge your usb devices for this unit making it very versatile. These Noco units seem very well built, the first one I purchased a few min ago has lived in toolboxes, bounced around in truck cabs, been dropped in the field, and it still functions great. Read more

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. Read more

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. Read more
