NOCOBoost GB150: 3000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 9.0L Gas and 7.0L Diesel Engines

Excellent booster with long battery life that is not difficult to use that fits in my car very nicely.

These work, often when other options fail. In two years I've only used it a few times, and it has worked spectacularly.One notable use was to start a dead F-250 Powerstroke diesel. A few minutes connected to the battery and it was able to start (and go get a new battery).Most recently I used it to jump a coworker's car at work. He said they had tried jump-starting with two other cars, neither worked. (obviously) Again, a few minutes on the battery and it had brought the voltage up from 5.7 to 12.2 and it started right up.Aside from the capacity and safety features of these, another great thing is that if you ever need to, you can jump start yourself. Something that is not an option with simple jumper cables.

Very good jump pack always works nice to have the voltage reading as well. I use it every day and the battery never dies on me during the day

This device is insane .I have been using standard 50 pound jump starters for years and they usually , but not always , performed sufficiently , and not always reliably . Lately , for the last 2 years , I have been dealing with a failing " battery saver module " in my 2007 Ford F350 CrewCab 4x4 6.0 diesel pickup . The short explanation is that when the outside temps drop below 60 to 50 degrees , the battery saver module kicks in . Once the days get cooler and the BSM activates it completely drains both batteries in my truck in about 2 days while my truck sits unoperated . My standard jump box just wasn't charging sufficiently anymore to jump my truck from a dead start , and about 2 weeks ago it completely failed even though it was as charged as it was going to get . After reading up on these type of jump starters and reading tons of reviews for different brands and sizes of these jump boxes , I wasn't completely confident that these things can or would actually operate as the manufacturers claim . I decided to purchase the NOCO GB150 mostly because ;1. They are an American manufacturer and ...2. because they have been manufacturing vehicle assistive devices for many years and have an established reputation and ...3. because their machines aren't built around add on cheap , junky , gimmicky crap like tire inflators , laser lights , compasses , radios , mini winches , etc....its just a solid jump box built into a strong , high quality housing with a useful , quality LED headlight and a few plugs for USB and charger adapters , and..4. it seems to have better overall safety features than the other comparable brands , plus it is rated for much larger engines , and I did not find any other brand offering a machine rated for such large engines and..5. In comparing the NOCO GB150 and it's parts such as the cables and post clamps to other brand boxes , the NOCO quality seems to be solid , professional quality .After receiving the box and examining it , it is my opinion that this is a finely manufactured product , no cheap or flimsy parts at all .Charging it completely out of the box as advised in the user manual took about 12 hours . The following afternoon I went out to my truck to start it up . It was about 3pm and the afternoon temp was about 75 degrees , and the overnight temp got down to about 49 to 53 degrees . My truck had been parked for 12 days without being started , and the batteries were completely dead . I attached the post clamps , waited about 1 minute , and keyed the ignition switch. The engine kicked over vigorously , no lag , no hesitation . I went into town to do chores and run errands , making several stops throughout the afternoon . I jumped my truck 5 more times that afternoon . When I returned home , I checked the box and the charge indicator gauge showed the box STILL at 100% . I left the box on the passenger side of the floor for the next use . I went out 2 days later , jumped my truck that morning and 4 more times that day . Upon returning home I checked the box and the charge indicator gauge showed the charge at 75% ! Think about that ...I jumped my 6.0 diesel 11 times over a 4 day periodwithout recharging this box , and it only used approximately 1/4 of the contained charge ..that is unreal .After reading the reviews , the only concern I had --apart from this box actually performing as the manufactures claimed it would -- was the complaints from a few customers that the power component ( battery pack ) failed rather early ...there were only like 3 or 4 reviews with this complaint ...in contrast there were hundreds of 4 and 5 star reviews for this box , none of which mentioned the box having a short lifespan or otherwise failing . Also , there were a few follow up reviews from guys who had purchased the box more than a year or more prior and talked about how the box was still functioning dependably as it was designed to do .One other thing to keep in mind is that should the battery pack fail , NOCO states in its user manual that it does rebuild the box should the owner send it in for such service .In conclusion I absolutely recommend this box or its smaller versions . In my opinion , NOCO builds the best quality box , and judging from other reviews , also maintains a responsive Customer Assistance department which is important as these jump boxes are not a throwaway item . Buy this jump box . 5 STARS !

I used my NOCO GB150 for 1 year and 1 month. At that point it stopped allowing me to recharge it. I will be buying another brand as a replacement.

Highly recommend. Works great. Connect to the battery and it shows the voltage in the battery. I like that , because I don't have to guess if it's a battery problem. Also stays in boost mode so you can move the vehicle off the road or to a safe place. And has a light to assist at night. Loving it!

Purchased this one and a smaller version for my son to keep in his car. The are both small and feel well made. I found it easy to charge. I used a fast charger that I already had for my phone. Took a little while but could not have been easier. The bag that it comes with is a good way to keep the few extra dodads like the charge cable.I got chance to use my GB150 yesterday. I have an old John Deere (Diesel) that is hard to start on the warmest of days. This was a some what cold day 35 deg at the time I did this. I did the norm, I tried to start the old girl with out the Boost and it turned over reluctantly a few times but it became clear it was not going to have enough juice in the on board battery to get the job done.I grabbed my Boost GB150 and hooked it up. Turned it on.. Note that I charged this over a month prior and it has been sitting in my truck under the back seat until now. I had read another review where someone had said that if they get cold, the loose there charge. Well its been cold.. In the 20s at times and well below freezing for weeks now. When I turned this on, I was expecting it to report that it was either dead or at least not at 100%.To my delight it stated fully charged. Blinked as it should when starting up and then I turned the key to heat the plugs a little more. Then after about 10s I tried to start it up. It turned over like a champ.. Honestly I think it turned over better than I have heard it in a long time. I normally have to let the starter spin for a good 20s to get things running. This was not an issue.It is big when compared to the other versions but it is not big when you compare it to breaking out the 200 AMP Starter charger.. In my case that would require running a line out to the back of the property. It weighs maybe 8 lbs I would say. Far more continent to use than any alternative I can think of.When I was done, I shut it off and disconnected it. A little later when I was putting it back in the truck, I turned it on again to see if the charge had diminished to a point where I would want to charge it. It was still claiming 100% so I don't think the start took too much out of it.Over all I am very pleased with the performance of the GB150. It is compact enough to keep one in the truck and not worry about it taking up space. I will be getting another smaller one for my commuter car now that I know they are the real deal. I also think it is so easy to use, I would not have much trepidation if my wife or daughter were to need to use one to jump their cars. Thinking about it now, for my daughter, this is a must. Never again would she have to ask for someone to help her jump her car if she had one of these in the trunk.I look forward to using this many times over the years ahead.Update(2018/01/04)Well I recently moved to a much colder climate and found that many of my battery started toys like my ATV or lawn tractor and even 2 of my cars had batteries that were just not up to the task of the much colder nights here. Where I was able to use thei GB150 several times to get me going again.. I did find that if the battery in a car is really done, this is not going to do the trick. I had 2 instances where this was the case. Once while driving on the NY Turnpike and at a rest stop. I was asked to help a fellow motorist jump there car. I was sorta excited since I had the GB150 on me and I had charged it just before the trip. I also had a trailer on my Truck this trip so I was not really able to pull up easy to do a standard jump. Well the battery on this fellows car was really bad. When I hooked the GB150 up it said 9.15V. then started to clime to 11.4 and sat there. we gave it a couple of tries and one of the times we waited easy 5 min before trying the start. It was a no go with the GB150. We then pushed his car to a place where I could pull up with my truck and trailer without blocking traffic and did a normal jumper cable jump. That worked all most instantly with me revving the truck a bit.I still think it is worth the money and is a quality product. Just don't leave your jumper cables at home.
