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

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!

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.

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.

I bought this thinking I'd probably never need it, but it seemed like a nice thing to have in case of an emergency so I charged it up once and stuck it in my trunk, completely forgetting about it until about 5 months later when I went to start my car and absolutely nothing happened! Car battery was shot, I measured a surface charge but any load on it caused the voltage to drop so low it wouldn't even spin the starter. I imagine this would have ruined my day in any other universe, but in this one I remembered the booster pack and grabbed it from the trunk - still 100% charged after sitting forgotten all summer! Hooked it up and started my car without issue, drove to the nearest auto shop and got a new battery - all sorted inside and hour, wasn't even late to lunch :) That was an awesome save, and about as real world as it gets on terms of testing the product. Very happy with it, very happy to have the peace of mind and confidence that comes with not only having the tool - but having used it and knowing it's going to work when I need it.

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.

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.

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.

Rock solid product. These things are awesome, I have two one for my v6 and one for our v8.. Stay charged extremely long time. Used once on my car, took like 30sec to setup and car cranked right up!!!
