NOCO Boost GB50: 1500A UltraSafe Jump Starter Power Pack – 12V Car Battery Booster, Portable Power Bank & Jump Leads - For 7.0L Petrol and 4.5L Diesel Engines

What a life saver to have this on hand, or in the back of your car! Gotten myself, friends and strangers out of trouble more than once! Well worth the price! Charges nice and quickly so you're not caught short, and ready to start your car when the power in your battery isn't up to the task! A nice sturdy build, and small enough to not worry about storing it anywhere specific!

Bought this a few years ago when our battery was constantly draining and it was so easy to use and never let us down. Since then a couple of neighbours have tried to jump their cars and failed and I have offered to use this and they have said don’t bother it won’t work. I said give it a try and both times it started them without a problem. It keeps its charge for several months.

Used this to start a strangers car. The were elderly and were expecting jump leads from my car they looked amazed. I have their battery charger too great quality products.

We have a 2.8 diesel Chrysler Grand Voyager. We've had trouble starting it over the years if it hasn't been used for a while, and it does NOT like starting in winter. This has been particularly bad recently, even with a fully-charged battery. This device has changed all that. Recent overnight temperatures have dropped to at least -4 and the car would not start, but started instantly when I connected the power pack. I've done this on a few occasions now, and it works every time. I did look at the GB40 but that goes up to 3.0 for diesels (I'm a 2.8) and a few reviews suggested that these devices might not quite reach their advertised thresholds. Rather than take a chance, I went for the more powerful GB50 and it's been great. The price goes up a fair bit from GB40 to GB50 but we need our car to be reliable and I though it was worth paying the extra now rather than regretting saving a few pounds later. The only downside is that there are no instructions on how to use it! I just went on YouTube and found a video easily enough. That's not enough for me to knock a star off the rating, but is a bit daft. The device is actually pretty easy to use. There is an option to deactivate the safety mode for when the battery is completely flat. I've not tested that, and some reviews suggested that this caused problems. In that scenario, I'd just whip the battery out and put it on charge.

Got this and, when my Jeep's relatively new battery recently died in cold weather, this thing managed to turn the engine and sustain it, despite my forgetting to reset idle. Once reset, I used this again and it turned the 3.7L V6 lump again. Afterwards, checked the levels and was only half-used. So this definitely performs and I'm well happy with this. The unit itself is deceptively small for the power, smart-looking and light, with quality charge cables (although these could be longer) and a car charger plug, handy for charging on the go. Downsides? Well as others have noticed, the instructions are tiny, especially for an old git like me, so this must be rectified at this price (hence only four stars). I'm sure there are those who had bad experiences who didn't know the right setting for a completely flat battery (you have to override it), and not everyone carries a magnifying glass with them, so this is a big omission. Also, for what it is, it is pricey.

I have a motor home with a 2.3L diesel engine which - depending on the time of year - can be parked up for a good few weeks at a time without moving. I got this because I was worried that I’d rock up at the compound during the winter months when the solar panel may struggle to keep the batteries charged and I’d struggle to start the van with a flat battery. It’s not happened yet. What did happen ( I now know ) is that the cab battery suffered cell damage so whilst away ( far, far from home) I couldn’t start the motorhome. Every time I needed to start it, I used the GB50 and it started in a few cranks. The alternator was generating enough leccy to keep the engine running once it was started but the battery couldn’t hold enough charge to start the engine. So each time I turned the ignition off, I used the GB50 to restart the engine. This means fuel stops, waste water dumps, stalling (?) etc So I reckon I used the GB50 maybe 7 to 8 times before I got it to a local place that could diagnose and swap the battery out. Performed brilliantly. If I didn’t have the GB50 it would have been a recovery job and I’d have to cut the holiday short. People weren’t always around to give a jump start. So yes, if that battery is as ‘flat as a witch’s tit’ it’ll start it but also if the battery was totally bust like mine then it *still* started the van. I’d rather not be in the position to have to call on the GB50, but when I needed it it saved my holiday. So now I’m an advocate 😃 What I would say though is that the distance between the HD leads is only good enough to reach between the posts of your batteries. In my case, I used specific designated jump start points in my engine bay ( Fiat Ducato - you must not jump start via the main battery due to ECU issues ) and these jump start points are further apart than the supplied leads will go so I used a jump lead as an extension to the HD leads as supplied. This shortness of terminal HD lead is the only grumble that I have.

Noco Boost XL GB50. Got to replace the ( SECOND ) Suaoki jump start & power pack. This seems better quality.

Excellent, returned home after an extended vacation: the car battery was so flat, it would not even turn the starter motor. Having anticipated this problem, I had charged my NOCO Boost, several months earlier. Once connected to the battery and car’s earth connection point, my car started on the key, first time, after I had reviewed a ‘learning video’ on a social media platform.

Buona qualità e affidabilità

Booster très qualitatif. Compact et pas trop lourd. J'apprécie la robustesse des pinces. Je précise que la charge se fait bien via un USB.C . Je recommande.

The title really says it all-this device is, to me, essential for your automotive toolbox. It is compact, lightweight, and does the job without ANY problem. The device & accessories are very high quality with a substantial feel when you hold them in your hand. No cheap look or feel to any of it-neither the unit nor the cables/accessories. The clamps that hook up to the vehicle battery are extremely strong & solid. The charging cable is a 2-headed USB-C cable (both ends are USB-C). They make a wall adapter head that goes with it but you will need an adapter to convert the USB-C to USB-A (I did that & it works perfectly...you an find those adapter pieces right here on Amazon). NOCO even included a nice microfiber pouch for the unit to sit in so you don't have to keep it in the manufacturing box/packaging. Side note - NOCO does make a very nice $25 carry case for the unit-it is like a little suitcase-it holds the clamps in one side in a little pocket, and the other side is custom-cut to fit the device itself. I bought the carry case & I highly recommend it. You can keep the device in the microfiber pouch & sit in the case-it fits great; keeps it protected while storing it in my vehicle. So, as far as the unit's functionality & ability to do what it advertises - I bought it solely to jump dead batteries I don't care about the flashlight nor will I be using it to charge any other devices (although I will say the LED light on the end is pretty good & handy in a pinch if you don't have an actual flashlight on hand)... Jumping dead battery: I have a Dodge Charger RT+ ...it is a 5.7L V8 Hemi - I hadn't started it or driven it for a LONNNNNNNG time (drove only 50-100 miles a month but several months in a row it would sit in the garage un-used and this went on all year long) so even though the battery is in mint condition, nothing wrong with it-it understandably eventually died. [It's important to note that the battery died for only this reason-if you have an issue with a sub-par or malfunctioning battery, this unit may very well not be able to do anything for you, obviously.] I fully charged the GB50, hooked it up to my battery terminals, turned the unit on-as soon as the GB50 came on, the colored lights started flashing left to right, red to green, and the little white light below it was lit steadily, meaning that it was reading my battery & I can try starting it---as soon as I went in & tried it, my vehicle started IMMEDIATELY without any problems or hesitation of any kind. Once started, you simply go turn off the GB50, disconnect the clamps, and you are all set! That 1 use right there has, in my opinion, paid me back the $150 I spent on it & then some. DEFINITELY worth the money. The ease, the portability, and the quality are all above & beyond my expectations. I have only 2 tiny "complaints" - The cable with the battery clamps is extremely short-it can come unplugged from the GB50 unit if you don't have the unit aligned straight with the cables...so just be mindful of that. I had the unit sitting at a slight angle to the battery clamps and so the cable unplugged partially from the unit. But, again, this is a tiny issue and certainly wouldn't stop me from recommending it. I am sure you can get longer ones as well. NOCO has a bunch of accessories but I wish they would have made them 3-4 inches longer. The only other "issue" is that the charging cable for this model is the 2-headed USB-C (both ends are USB C) that i mentioned above, yet the NOCO wall adapter head that they recommend for it is a USB-A female connector. So just keep that in mind when you buy this. I have nowhere to plug in a USB-C head for charging so I needed the wall adapter. As I said earlier, it charges perfectly using the USB-C to USB-A adapter pieces. Lastly, I will mention that the unit itself was almost fully charged when I received it, so it did not take long to complete a full charge. It claims you can do 20+ jumps without having to re-charge the unit but I have NOT tested that claim-I have only used it 2 times and they were on separate dates & the unit was also fully charged prior to using it each time. However, based on how it performed for me, I see no reason why that claim would not hold up. Bottom line, this is a GREAT unit and I highly recommend it to all who are interested.

Only used once on a strangers car and it worked well. Held the charge for a while.
