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

Prompt delivery as always with Amazon, the battery pack did exactly what it should do, I no longer have to charge up the battery on our 'spare' car one that only gets used once or twice a month and in the cold weather the battery looses its charge quickly so I used to have to plug it into a mains charger. Upon receipt of the NOCO Boost XL GB50 I plugged it into the USB port on a wall socket, charged it up. The next day the spare car wouldn't start low battery, 2 minutes later I was up and running its so easy to use the crocodile clips hook up to the battery terminals easily plug it in to the charging pack turn it on and happy days I was all ready to go. The handy bag makes it easy to store and keep all parts/leads all together. I've also have my motorcycle on permanent trickle charge as its not used too much in the winter went to start that the other day and after three or four attempts the battery didn't have enough power to start the bike so hooked it up to the NOCO Boost XL GB50 and hay presto loads of battery power and got me going!! Highly recommend the NOCO Boost XL GB50 excellent bit of kit and easy to carry in the boot its nice and compact.

I moved to a new place, local shops about a mile away, being a lazy ass I kept using my car over and over for short journeys, suddenly a couple of hard frosts hit and it wouldn't start, just that click we all know. I did lots of research, buy a battery charger or buy a jumper, I decided to buy a jumper, why? I decided a battery charger is no use to me if I am out and the battery goes flat, at least with a jumper i could get the car going, drive around for 20 miles keeping the revs above 2,000 and it would charge half the battery, making a mental note to do a decent run sometime within a few more days. The NOCO Boost XL GB50 was my choice because I had read bad reviews about similar products with ratings for a particular car or engine size were fails, so I went for something powerful, much more than I needed, my thought process was if over time it starts to become old and holds less charge, it will still hold enough for what I need (I have read they slowly lose a holding capacity). Right, it arrived, 25% charged, it uses a USB connection to finish the charge, I simply plugged it into a USB port on the comp and 3 hours later, fully green charged. Next day arrived so I decided to give it a try, red to + black to -, turn it on with the power button, got inside my car, turned ignition to click one, waited 10 seconds and tried it, fired up instantly, no strain, no difficulties, instant power from such a small power unit, I took the NOCO Boost XL GB50 inside after my journey and re plugged it into my comp USB and it had lost approx 10% power only, 20 mins later, fully charged again, it is now going to live in my boot, you never know if you accidentally leave something on when out and flatten your batter, you do not know if your battery is on it's way out and you get stuck somewhere, with this unit I can honestly say I have absolute peace of mind knowing it is with me, and if someone needs help, you are the Knight in Armour to the rescue. I honestly recommend this, Ok it is not cheap, but for peace of mind, it is a bargain.

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.

I bought this to primarily use with my Aprilia RSV1000... an old Italian 1000cc V-twin motorcycle renowned for starting issues in cold weather unless your battery is perfect (and I have a Noco Genius10 looking after the admittedly pretty old AGM one on this) and/or that you use the bike frequently. To be fair, this is overkill for this application given its claims to be able to crank an engine six times the size. And so it would prove. Every time I have left the bike for a couple of weeks out in the cold weather and it has refused to start under its own steam... I plug this in (using the highly recommended - if a bit expensive - Noco GBC007 cable if you also use a Noco Genius charger... but a Noco GBC002 will do if you don't) and as sure as eggs are eggs, it will start... even on those horrible 'wide open throttle' long cranking starts, this thing does the job easily. There appears to be way more than enough cranking amps available as the starter spins fast and long and the engine really doesn't have a choice but to fire. As I said, it may well be overkill for this and it's likely that the bike isn't really testing this at all... but in this application, this guarantees a started motorcycle. From fully charged, I've used it maybe a dozen times and it's still showing a green charged indicator so it's definitely not really being challenged. On a 3 litre diesel, probably a different story. Hard not to recommend it though. Easy to use. Compact. Looks the part. Starts the engine. Job done.

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.

Excellent product and value for money easy to use

First shock was seeing just how small it was (compared with the giant lead acid battery it would replace for a few seconds). Second shock was realising that that this device charges with a simple USB cable. After toping up the charge (a process of about 4 hours conducted the night before car start time - and which caused my 2.0A USB charger to warm up in a slightly alarming fashion) I was ready to go. I connected the leads to relevant posts on my car. This confirmed my suspicion of total battery death as the GB50 device was unable to detect any viable current from the car battery. Following the GB50 directions, I pushed its "throw caution to the winds" over-ride button to force the connection. My third shock came when I turned the key of my ageing BMW petrol SUV and ... BAM! Instant start! No hesitation, deviation, or repetition. I switched off the device and drove off into the sunrise for a great day. Hard to believe a device of This size cranks an engine of That size. But it does. More details: I used this to jump start my 3.0L petrol (gasoline) engine SUV, a task for which this product is supposed to be seriously over-qualified. I decided to purchase this 1500A GB50 (rather than the 500A GB20 rated for petrol engines up to 4.0L) because: I'm starting a 2004 BMW 6-cyl petrol engine on an SUV, I knew that my (recent vintage heavy duty) battery was dead dead dead due to COVID lockdown long non-use, I couldn't quite bring myself to believe something this small would work, I live in a city apartment with no off street parking so I have no "plug in" options to charge the car battery, I was worried that I might need to start the car multiple times with limited travel time to allow the alternator to do its job properly (assuming the car battery would hold charge), I believe in over-provisioning to avoid disappointment, and... the GB50 compared to GB20 was 3x Amp at 1.8x cost. I figured if this works I'll keep it a long time. It did. I will.

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.

Parfait !!!! Déjà utilisé pour dépanner pas mal de Voiture. Je recommande à 100%

Flabberghasted how much power my Noco 1500A provides. Besides being able to charge any battery, it also offers great LED-light when it's dark. Complete package and a must-have for every car-driver. Offers a comforting feeling having this in your back of your car while driving far away. You can even charge your Iphones. Much value for little money. Ps you even got a backup when current in your house isn't provided by the grid...Absolutely happy and remommendable.

Top Produkt. Gelegentlich musste ich schon schwache PKW Batterien damit etwas aufpäppeln. Grundsätzlich ist das Gerät aber immer den ganzen Winter über an meinem Motorrad mit der Funktion Batterie Erhaltung. Wenn der Winter vorbei ist, klemme ich das Ding ab und kann problemlos das Motorrad starten.

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.

I have one of these and bought this for my son. They are great. The hold their charge really well and have saved me multiple times from being stranded. They are so easy to use and I use it on a van with a large battery. I originally bought a cheap one and it didn't even work once. Worth paying the extra and getting this brand. Highly recommend!!!
