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.

Great product, bad on Amazon for taking so long to ship

I use this booster pack as a tow truck operator and it does the job everytime!

I bought this about a year and a half ago and have used it many times since; my car gets crabby in the wintertime. It's small enough to carry around with me (when it's really cold outside, I try not to leave it in the car) and it recharges quickly enough for my needs. I definitely appreciate that I can jump my car multiple times before needing to recharge it, though. I'd definitely recommend this.

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!!!

Let me share a real-life scenario where the NOCO Boost XL GB50 proved its worth: Last winter, during a particularly frigid night, my car battery unexpectedly died. Thankfully, I had the NOCO Boost XL GB50 with me. With its 1500 Amps of power, it effortlessly jump-started my vehicle, defying the freezing temperatures. The built-in flashlight came in handy, providing illumination as I worked to revive my car. With its UltraSafe technology, I felt assured that my vehicle and the booster were protected from any voltage irregularities. The NOCO Boost XL GB50 isn't just a device; it's a lifeline for drivers facing unexpected challenges on the road.

Easy to use

Initially wasn’t sure about this but has lived up to its promise. After toting the big booster pack this is so much better. It is definitely lighter in weight. I have charged cars and trucks without any issue. It keeps a charge for a very long time. Has a carrying pouch and connection cables are easy to disconnect/connect to it. I just wish I could find where to just order additional cables. LED screen shows how much charge is left on it. It is expensive but well worth the price. I now see tow truck drivers using these/this brand.

El NOCO Boost XL GB50 es un arrancador de batería impresionante, ideal para cualquier emergencia. Con 1500A, es lo suficientemente potente para encender baterías de 12V en vehículos grandes como autos, SUVs e incluso camionetas, todo sin esfuerzo. Su diseño UltraSafe asegura que lo puedas usar sin miedo a chispas o conexiones incorrectas, lo que lo hace perfecto para quienes no son expertos en mecánica. Además, su tamaño compacto y ligero lo hace fácil de transportar y guardar. También funciona como banco de energía para cargar dispositivos móviles, lo cual es súper práctico. Si buscas un arrancador confiable, seguro y versátil, el GB50 es una compra excelente. ¡Indispensable para cualquier conductor!

I bought this car battery booster a few months ago when my car battery died and I had to call for help.I am very happy with it. It is easy to use, compact, and reliable. It has saved me a couple of times until I was able to replace the car battery.It is an excellent emergency product that should be mandatory and I would recommend to anyone who needs a backup power source for their car. It is worth every penny!

This battery booster is very reliable and easy to use. The only disappointment are the clamps.After the second use. The plastic that covers clamp chipped at end. It very cheaply made plastic.Too bad. The machine itself is excellent.

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.
