Boost GB50 1500A UltraSafe Jump Starter, 12V Lithium Battery Booster | Spark-Proof & Reverse Polarity Protection, For Car, Truck, Motorcycle, SUV, Boat, ATV, RV, up to 7.0L Gas & 4.5L Diesel

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.

Still works after a year! Of course the charge will go away if unused for several months, thats expected for any other electronic. Easy to use for grandmas, charging still works great. How much power it uses is also amazing, I let my mum borrow this and she used it about 10 times every time she had to go somewhere and it kept all bars of charge. Fits easily in my backpack in case I ever need to help a stranger, friend, or myself when I'm out delivering mail and packages.

I recently bought the NOCO Boost XL GB50, and it’s already saved me a couple of times. This little jump starter is super compact and easy to store in the trunk, yet it packs a serious punch. The first time I used it, my car battery was completely dead, and the GB50 brought it back to life in seconds. One of the things I love about it is how user-friendly it is. The instructions are straightforward, and the built-in safety features give me peace of mind that I won’t accidentally fry anything. Plus, the design is really sleek and sturdy – you can tell it’s built to last. It’s not just a jump starter either. The built-in flashlight is surprisingly bright and handy for nighttime emergencies, and the USB port is perfect for charging my phone on the go. I haven’t needed to use it for anything beyond jumping my car yet, but knowing I have those extra features is a nice bonus. The only minor downside is that it takes a bit of time to fully charge, but considering how long the charge lasts and how powerful it is, that’s a small price to pay. Overall, the NOCO Boost XL GB50 is a must-have for anyone who drives. It’s reliable, easy to use, and worth every penny.

Had it almost four years now. Still works good. One of our trucks goes dead if you leave it sit for more than three days so the boys rely on this thing a lot more than they should. They claim you can jump the truck many times before you have to recharge it.

Talk about a life-saver! As a person who drives a pick up truck during cold, Michigan winters, this baby REALLY comes in handy when in a bind. Rather that paying $60-70 bucks to a tow company for a charge or trying to rely on the 'unreliable' kindness of strangers, this jump starter is just what the doctor ordered. It's small, durable, easy to use, and holds a bunch of starts on a single charge. Well worth the price!

CAR BATTERY DEAD? How often did you forget to turn off the interior lights? For how long did you not drive only to find out your car would not start? I lost count. My family, coworkers, strangers, and I all had that happen before, and when it did: - Was a jump start cable available? - Was anyone available to lend their car to power yours up with? - Did you know how to jump start a car? - Did you have a AAA membership, and did you have time to wait for a technician to arrive and help? My dad bought me a battery-operated jump start kit decades ago when I was in college. It was large and constantly lost its charge. Technology had changed since and small, powerful batteries now exist that can start a vehicle as large as a truck. MODEL GB40 PLUS (1,000 Amp) ---------------------- I had purchased a NOCO Genius Boost GB40 in 2016 for the sole purpose of having an emergency jump starter available for my SUV. Its feature set intrigued me: - Compact and portable at 2.4 lbs -- Does not need you to move your car so the battery could reach the other vehicle’s -- Just take out the NOCO, connect to your own battery, and start - Ability to jump start a 6L gasoline or 3L diesel engine -- My V6 engine SUV only uses 3.5L gas -- A Ford F150 truck with V8 goes as high as 5.0L - Up to 20 starts - Boost mode to send maximum charge to a completely dead battery -- 1,000 Amps — yes, really! -- This saved our butts many times — at least we were able to drive back home until we got our batteries replaced - Reverse-polarity protection to ensure you won’t short the battery if you connect the clamps wrong — FYI, red cable should always go to battery’s red or plus (+) terminal -- Having the clamps touch each other also does nothing. It’s quite fool-proof - microUSB re-chargeable in less than 3 hours - Battery to charge USB devices with - Built-in flashlight with SOS function - Battery maintains its charge for months MODEL GB50 XL (1,500 Amp) ------------------ I bought the 1,500 Amp NOCO Genius Boost XL GB50 model in 2019 to keep at home. - Can start a 7L gasoline or 4L diesel engine - Up to 30 starts - Battery recharges in 5 hours - Weight: 2.7 lbs, just 0.3 lbs heavier than the GB40 model USAGE Using the NOCO Boost is simple: - Ensure car is fully turned off, including all lights - Put car into Park and activate the hand brake - Pop open the car’s hood and wait 30 seconds - Plug the Boost’s red clamp to the car battery’s red or plus (+) connector -- Even if you plug it to the wrong one, the NOCO’s reverse-polarity protection will prevent your battery from getting short-circuited - Plug the black clamp to the car battery’s other connector - Turn on the Boost - Start the car and push down a bit on the gas to rev up the engine - If car starts, let it run for a few minutes -- Drive your car around for 30 minutes to charge up its battery a bit. It may simply need a few hours to fully recharge unless the battery is completely dead and requires a replacement Warning: Do not leave the car running inside your garage with the doors closed. You could get carbon monoxide poisoning and die! - If car did NOT start, wait 30 seconds -- Long-press on the NOCO’s Exclamation mark (!) button to activate maximum Boost mode -- You will see the light above the “12V 1000A” label turn on. This mode will send the maximum charge to the car battery -- Start the car and push down a bit on the gas to rev up the engine. It should work --- I had NOT come across a single car that could NOT be charged when the NOCO was set to its maximum boost The NOCO GB40’s small size once wowed a AAA driver when I showed him that it could start my mother-in-law’s completely dead battery. He showed me how large his one was. (That was not a dirty joke!) CONCLUSION This is one of the single, most important pieces of emergency gear I had purchased for myself and each family’s car — so you would not be stranded somewhere without a cell phone signal. Both models are very powerful, do not take up much space inside the vehicle, and are easy to use: my elderly mother-in-law remembered how to start her own vehicle after showing her just once! No more waiting for a tow truck/technician to arrive, and having been able to use the NOCO as a portable battery to charge my mobile devices with has been an added bonus.

Excellent product, excellent quality. Buy it without hesitation.

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.

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!

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!!!

Helt underbar. Koppla på batteriet, tryck igång och titta så vit led tänds och starta sen. Är batteriet helt total urladdat och boostern inte känner av batteriet kan man köra en override och tvinga den till startström. Räcker till ett gäng starter innan den måste laddas. Jag har använt den flera gånger (på samma Laddning) på en kall 3.0 diesel. Helt enkelt toppen
