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

I’ve always been a stickler for monitoring battery health, but things can happen rapidly as a battery ages. Since I bought this battery booster, I’ve used it twice on a touring motorcycle before replacing the battery, once on my wife’s car before replacing the battery, and a handful of times on a riding lawnmower while trying to finish the mowing season on the old battery. It has worked great every time. I’ve never used the USB ports to charge or power another device. I charge the battery booster using a 2.1 Amp USB cable, in a cool environment to avoid swelling the booster’s battery. Yes, it’s quicker to charge it other ways, but at the risk of swelling it and breaking the plastic case. And I never let it get hot.

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.

This is a must! I recently started having issues with my car battery and luckily, I had ROADSIDE ASSISTANCE, which covered a jumpstart the gentleman that gave me a jumpstart was using this very same device. Now mind you, I already had a portable jump starter, but for whatever reason, it was not starting my battery with this device as soon as it was hooked up to my battery, it turned my car on without a problem.. I purchased one of my own a few days later and since I’ve used it on my car, which was over a week ago, I have not had any trouble with my battery at all

I was recently out of town for business for a cpl of weeks. When I got back to my sailboat, all of my batteries had sulfated and would not start my 46hp diesel engine. Got this unit changed it up, and it fired my engine right up. So far great product. It charges all my devices and give me piece of mind I can get my engines started if something happens while in a remote location. Definitely recommend this to sailors, RV-ers and anyone doing any off grid adventures.

Have used for 2 recoveries, one a late model Ford Ranger, and the other an M1 Abrams tank while under fire from the Taliban. Let’s play a game. It’s called 1 truth and two lies. May the odds be ever in your favor.Good quality, charges phones and has a light when needed. Make sure you read the manual about the proper use of the red button.

the owner's manual did not come. The owner's manual didn't come, but the jump starter worked fine.

I purchased this to keep in my truck for emergencies and to help anyone in need. I have used it twice on my own truck due to a faulty battery. It saved me 2 times . This one is perfect for my 4x4 truck. Also if you have a loose post on battery it will have all lights on GB70 letting you know there is an error. After tightening ground and positive post GB70 light would start scrolling letting you know your ready to start vehicle. Mr Fowler

I was originally was gonna buy the 150 - 3000 but the reviews on this one was fantastic,works just as said ( tried it on our tractor and 1 try it started) bought for my personal use since my battery is notorious known for going bad in the car we just bought,the dealership had one of these and I lived the size ,so here I am, writing a crazy review,I say it's worth the money,if anything changes I'll add on to this review. Love the compact size , just great !!!!
