NOCO Boost GB50: 1500A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 7.0L Gas and 4.5L Diesel Engines

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.

We think this is the best battery charger on the market. Have one in all of vehicles & gave many of our family members one for Christmas. They are durable, work well & are compact. Easy to use. Sometimes paying a little more is worth it for the peace of mind that the charger will work when you need it the most!

This jump starter works great. I’ve used it on my 5.7L HEMI with a completely dead battery and it started right up without any issues. It’s easy to use, feels well-built, and the safety features give peace of mind. The size is compact enough to keep in the truck, but it has plenty of power when you need it. I’d definitely buy this again and recommend it to anyone who wants a reliable jump starter.

TLDR; Worth the buy. Worked exactly as needed. Good tool to have on hand. "Better to have it and not need it, than need it and not have it." I had neglected to start up an 06 Infiniti sitting in the heat for a couple of weeks when the battery was already going bad. Don't judge! I bought a new car. So, since I always intended to own a portable jumper for times like this, having no cables & instead of bothering anyone with a jump, I pulled the trigger and bought one of these units. (12V 1500A) Getting to the point. Worth the buy. No problems upon use. I of course had to charge it completely which took somewhere between 4-6 hours. Upon hooking up to the battery ***it did take a minute or two for the car battery to "receive" the charge,*** but once it did, the unit started making a clicking sound, the power LED Indicators on the unit started cycling (which to me suggested the unit was officially feeding the car battery) - went to turn the key in the ignition and voila, car started up without skipping a beat. Remember folks, if a power cell has zero charge, it's not going to instantly come back to life when you hook it up to a jumper or other battery! Give it a couple of minutes at most, but any longer, it would be safe to assume the battery is totally dead especially if the unit is non-responsive when you hook it up. The unit itself is nice and compact. The box packaging is sturdy enough for you to regularly pack it back inside its box - if you're that sort of person, I am - but it does include a surprisingly NICE quality/material storage bag. The Jumper Cables are a tad short, but understandably for the purpose of being compact. I myself had no issues reaching my battery with them, but could pose an issue to those with a hard to reach battery. The dual LED illumination lights definitely supply you with some decent light, and would certainly be visible at night on the road or get you around your house in a power outage, but I would not recommend it be used as a primary light source. It also includes a USB port for you to connect a charger for your devices. I understand others have later reported that their unit died on them. I'll cross that bridge when I get there. Though, I would imagine as long as I don't keep it sitting on a charger, don't use it unnecessarily, and only recharge it if it actually becomes depleted - it should last. I recommend this product. 👌 Thank you for reading!

This is a great jump starter. We bought it mainly to take with us in our motorhome when travelling. We have used it twice on trips, and a couple of other times when people have needed a jump. It works great. So much easier than jumper cables and 2 vehicles.

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.

My late model F-150 sat for a colder than normal couple of weeks over the holidays, and when I went to start it, the battery didn't have enough juice to fire it up. I had wanted a jump pack anyway so I read some reviews and ordered the GB50. It came with a USB cord and a car power adapter for that, but no AC plug... not a huge deal, just something to keep in mind. I read the manual and then plugged its USB cord into an old Samsung phone charger I had sitting around waited until the lights went from red to green... roughly 2 hours from one red light to full green. I tried to crank the truck again but the battery was almost completely gone, almost no response at all. I then connected the GB50, waited for a few a seconds, heard it click, and then tried to crank the truck. It fired right up, no problem. So far I'm pleased. Build quality seems good, and the unit is lightweight and compact for the power it provides. Having a light wasn't something I was really looking for but might be useful at some point, and being able to function as a power bank for a USB device might be useful as well. I like that this unit has some protection built in, both in that I don't have to hook my vehicle up to someone else's if they need a jump, and for cross wiring if the unit was plugged in wrong. Note that for a very dead battery, there's an override option to turn the safety features off and just provide power, which might be needed if your battery is totally dead and the unit can't sense it once connected. I have a fairly new battery so I didn't need it this time, but for a completely dead one it may be required. Hopefully I won't need it again any time soon, but if I notice any issues in the future I'll update my review.

Have owed the GB50 XL (1500A) for over a year and I've had to use it twice on my 2003 Chevy Silverado 1500HD Crew Cab (6.0 liter engine). Both times, it performed flawlessly under the conditions it was used. First time, on a nearly 5-year-old battery. Second time, on a newer battery that was being drained by a faulty A/C control unit that was purchased off Amazon (thinking it was either a bad refurb, or a cheap knockoff). Both times, the battery was below 2 volts as the Boost LED light was off (i.e. not illuminated). In those cases, below 2 volts, the unit didn't jump start the battery. Wouldn't even make a noise trying to turnover. Fortunately, it has a "manual override" feature. In those cases, I pressed the manual override button for 3 seconds as indicated in the instructions, and the truck sprang to life immediately. So not only does it work when needed, it's incredibly easy to use and very easy to connect. A far superior option that dealing with the much larger jumper cables and trying to (1) find another vehicle willing to help and (2) dealing with aligning them, if possible, to allow the cables to reach. Each of the 5 vehicles in our family has one of these, each rated appropriately for the size of the engine in them. As a bonus, they have built in lights that can be used in the dark if needed...and, they can be used to charge a phone if needed. We will never go back to using jumper cables. Only thing to remember is to keep this unit charged. We set a reminder to check the units 2x a year to make sure they are charged. Highly recommended!
