The first time I used the device it became extremely hot and blew the hose out while trying to pump up a tire

Without the booster, when I turned the key, the engine turned two or three times... slowly... and slower... but wouldn't start

Junk, failed 1st time, now won't charge, and can't return it, and warranty is useless, dont buy this junk!

I've used it multiple times over a few year and works great.

The directions are straight to the point and the Jump Starter Pack worked like a charm saving me the time to wait on a jump from my insurance carrier's roadside assistance.

Every time i try to jump start something including my lawn tractor it dies very quickly

This is great to have at home for those unexpected dead batteries that always happen enough times now to make me want a home solution without having to have a second vehicle on hand to jump or to have to call and wait on my insurance roadside assist

Worked first three times.

Within that time it has only worked the first 2 times , maybe within the first 3 months I owned it

this is a lot easier and has worked every time

This sweet little beastie has performed well each time I needed it

Our unit worked great exactly two times

I’ve used 4 times for my older Jeep Wrangler already and it worked flawlessly in times of great need

Has worked great every time.

Don't waste your time if you live in colder climates.

Don't waste your time with jumper cables!!

It worked the first time (on a fully charged battery) on a 3.8 liter 6-cylinder engine - so now I am really sold on it and a true believer.

I've been the hero a few times for helping people out, and an embarrassing mess when the unit is dead

Works every time the first time.

Started my tuck, no problem, multiple times in one day without charging.

With little to no driving and the cold weather, almost dead battery every time I had to go out

Major Problem: Maybe the weak connection of the negative clamp I describe above is why it hasn't worked the two times I've tried to jump the van's dead

It succeeded each time

It is replacing a hefty lead acid battery starter, which is easily 10 times the weight of this unit and I suspect that this unit is more powerful.

Product working good, used to jump start 3.0 Diesel, not once, but 3 times in a single charge and still have 75% power

The only thing I would say is to improve the total charging time when utilizing an IPhone type charging cable.

This jump starter is not "20 jump starts on a single charge" at all, I only jump star my V8 SUV one time and drain out of power, I have no way to jump-start 2ed time anymore

Have used the gb40 a few times and worked well

It worked the first 2 times and third time not a charm because when I went to jump my car on the side of the road it failed

Saves a lot of time and worth every $ ... have used it more than few times on mine as wells as friends cars ... so easy to use and delivers every time!!!

Make sure you have this some place you can get at it easy as the second time my SUV had a dead battery it was with the spare tire and since everything is needs

Doesn't work, don't waste your time

Try using it a second time and nothing happened won't work

After using Roadside Asst. several times, i purchased the NOCO Boost

Another time last year, I had the same alternator issue, and was able to drive it to and from work (2 miles round-trip) everyday for two weeks till I could afford to replace it

I have used it several times while working on a truck that has been sitting over a year

Though, there are no fancy charging technologies, so don't expect super fast charging times

came in good time

It works every time.

I work in a auto repair shop shop and have used this unit a handful of times and it has worked about half the time

Works every single time and haven’t charged it in months

For some reason I have had a hard time getting anything to start with

There is no convenient time for a battery to fail

Works every time

The first one worked one time and then died after the 30 day return period..

It worked great the first time but hasn't jumped a car since

My new SUV battery died a few times and I had to call and have it jump started.

The larger one helped a few times and worked flawlessly each time.

I have boosted it twice, the second time was without recharging the Jump Starter

It works every time for 26 consecutive times and the battery stills showing 50 % left

Bought this because my cars battery has gone dead on me three time in the last two years this unit when charged works great

Don't waste your time with NOCO products

I have used this Jump Starter a few times and it works great

They have now failed 3 times out of 3 attempts to jump a partially discharged battery

TLDR;My new NOCO Boost Plus GB40 started my 4.7L V8 a dozen times on one charge so far

I have already used it a few times and it works like a charm.

Jumped my VW bug convertible countless times so far

Worked flawlessly each time.

So basically, if you want to use it to jump start cars in an emergency, and occasionally charge devices, I have a hard time justifying this over other (cheaper) options

Worked just as good that time as well

Worked just as good that time as well

Great device that has come in handy multiple times.

I've been the hero a few times for helping people out, and an embarrassing mess when the unit is dead

Used it first time 3 days ago worked great my cousin was right great product.

Has worked every time (4) on my 2000 Mercury Grand Marquis.

I've been needing to buy one and kept putting it off for good time and sure enough, it got to the point that with covid going on, I really don't drive as much and since I live in an apartment, not able to order a trickle charger

Used it only a few times, but works flawlessly.

This thing has worked like a champ each time

I was extremely impressed, as last time I had to jump it, I hooked it to my wife's car and had to let it sit for 40 minutes charging before it had the juice to even turn it over

I’ve used it a couple times and it worked flawlessly.

So glad I purchased this, it saves so much time especially when one of the kids needs to use the car to go to work

It worked every time for the span of about 5 days

Very Easy to carry and can save you in a stressful time

Worked several times for dead battery and charging cell phone when out in the woods.

I tried it the first time and it didn't work.

I've jumped two 4 cyl engines off one charge and both times it was powerful enough to turn over with no issues

Unfortunately, my battery has died several times and I've had to use this pack three times since I've had it.

I tried it 4 times and at all attempts it failed to start the car

Each time it worked as expected.

1ST Time I needed and didnt work at all NOTHING !!

Every time I try to start a car, the device just has a click noise internally and fails to start the vehicle

I used that product 4 times since leaving on a dead battery and it worked evry time.. quick charge of about 2.5 hrs

Over the cold winter my new battery died several times.

yes I fully charged it before first use...they claim it can boost 20 times on signal

The power and flashlight buttons are far too convenient, and more times than not they are inadvertently turned on during storage

One time while headed to work, a woman flagged me down

So the next time my car died I was ready.

Saves valuable waiting time for a tow, or jump.

I’ve used mine several times now and LOVE it.

Has used it a few times already and has recommended it to even his pickiest of friends.

My friend has a Denali with a V-8, and the GB40 has worked for him several times.

this time it lit up it was ready and the van started right up

You will especially love it the first time your battery is dead and it gets you started without lugging around a 40lb jumper pack.

Of course, only time will tell if it works over the long term, but so far, I love it.

It worked instantly every time

Bought this because my cars battery has gone dead on me three time in the last two years this unit when charged works great

I have used this boost three times already.

Has failed me the last three times I needed it

He said it's like magic every time.

The first one worked one time and then died after the 30 day return period..

I have already used it a few times and it never fails

It was to be an in-vehicle back-up to my Subaru's Outback battery which tend to drain out over time--- I had it fully charged and it worked the first time.

This unit worked both times without a hitch

I've used it to start my dead battery 2 times now and it worked every time.

Every time, this thing just works

I’ve used this many times on numerous vehicles and it works very well

Not sure if that time is par for the course or not but it didn't bother me.

It worked like a charm each time, and it had been sitting in my car for two months before one of these occasions

multiple times it works like a charm so far , charged it up once at home and put it back charging when done thru the AC port in the auto ..if anything changes I will post later

I use the jump pack one time and it worked perfectly

Doesn't work, don't waste your time

She has been rescued from a bad day three times within the first month

Although it offers lower amp models those can sometimes have a hard time jumping a VERY dead battery or a battery running a large vehicle such as an F150

I was jump my van 5 times from completely dead on one charge of this charger

The first time the car (1999 Lexus RX that is not garaged and that I don’t drive very much) would not turn over but the lights flickered

Every time my car battery needs a jumpstart, this product works quickly and effectively to do the job every time

I think my only issue is that the manual was printed so tiny, I had a hard time reading

It worked the first 2 times and third time not a charm because when I went to jump my car on the side of the road it failed

unit is a life saver works every time

Very easy to use, battery last a long time, and super easy to store.

Very easy to use, battery last a long time, and super easy to store.

The times it did use it was reliable

Works every time!

Already used a few times, no issues, works very good

I used it one time within the first 30 days of purchase, and it worked

Used the charger a few times already and worked everytime when jumping a dead battery

Worked great every time

Well, the time came for this product to be put to test

Quality seems to be there , but time will tell how well it works

The first time I used this it was unable to get the 3.0 L diesel engine to turn over.

I have used it many times over and it has never failed to work on the first try!

I would not feel very confident the next time I need to use this.

Hope came back in my eyes when the interior lights came on, the wrong clock time popped up (fixed later before relief for the morning while I work nights), and the fans were blowing; followed by the starter motor and the main engine popping off on a 2003 Chevy Trailblazer.

I needed to use the charger 3 times before I was able to bet the car problem fixed, and it worked like a charm each time

Great timing

4.6l with ease multiple times and still has juice to jump other vehicles

Works great every time

This thing works like a charm came in handy some many times already off a single charge

I love this and it has come in handy several times

We used it 3 times in the last 24 hours and it works perfectly, as it should.

The first time I used the device it became extremely hot and blew the hose out while trying to pump up a tire

It got real hot trying 1 time and now won’t take a charge at all.

My wife complains each time she tried and I presumed it was user error (sorry honey) but either both of us don't know how to read instructions or we have vehicles it won't work on

To get the thing to start I had to crank the car several times with rests in between, completely draining the NOCO.

I'll update my review if it has a hard time with my 6cyl 3.0L

Works every time we need it.

used multiple times- works like a charm every time-

The time I actually needed it, it failed

Worked great first couple times

I used it three times over 1-1/2 years and it didn't work the third time.

This worked great the first time i used it to help a stranded car.

So after roughly eight months of sitting in my car and two uses, it would have still been usable possibly two or more times.

We've jumped 20-30 cars/trucks, and its worked great every time.

It turned over a few times and then drained the battery.

Lost confidence in this jumper the time I needed to use it was dead and won’t charge

Works great jumped my 4.0 Tacoma multiple times before recharging

Has worked every time I needed it

Don’t waste time.

she didn't own jumper cables, and this was gifted at the perfect time

the light worked one time

It has failed me time after time now

5 or 6 times worry not a problem

The second time I had to use it, my battery was dead at 6 volts out of 12.

no problem, multiple times on only one charge!

Didn’t work the next two times….You have to constantly recharge it or it won’t be ready when you need it

A great product for an unusual time.

works every time and gets me to the auto supply to get a new battery without having to call someone

I figured this would give the car's battery enough time to get a little charge back on it.

Works perfect every time.

I've used it a few times on my Ford truck and it would work perfectly every time

Some times another car isn’t available and you may be physically blocked.

The first time, it worked immediately

This thing did the trick each time

Works great have easily boosted gmc 5.7 several times

Works great have easily boosted gmc 5.7 several times

This time we got the same error of the cords being connected to the wrong terminals

Used it several times on other people's vehicles and it's worked every time

He said it was a great time to test the Noco

5 or 6 times worry not a problem

My car was having a hard time

Ive now used it to jump a 1.6L,3.8L,4.3L,6.2L,and 7.0LAnd its worked perfectly each time

It works each time and have not recharged it yet

I received two units in November, I knew one of them was defective because it took like three times as long to charge as the other unit.

Was very easy to use but failed the 4th time we needed to use it

Tried to use the jump starter a second time on a different vehicle and also didn't work.

Lost confidence in this jumper the time I needed to use it was dead and won’t charge

So far used it 3 times and it worked like a gem

Not happy first time using this product.

My first time needing to use the Noco and it failed miserably

Worked both times and still has a full charge!Was so impressed I bought my daughter one for her vehicle as well.

I used this to jumpstart my car 4 times and still works great

Has come in handy so many times already

I have used this about 16 times now on my car and it works with no problems.

, didn’t work either time.

I am notorious for forgetting to turn the car off at times and it drained the battery couple times

Has saved our rears several times now on a long road trip when our battery crapped the bed in the middle of nowhere

I've used the GB40 three times already and it worked flawlessly and with as little effort as you could possibly want

Easy to use , has worked every time

Used it 5 times, worked great!

Unfortunately each time this thing failed to jump the vehicle

n’t go wrong with it

n’t know why the car dies after I put car in D mode and drive a few feet

n’t drive it as much working from home

n’t recommend it for cold weather.

Its great AND CONVENIENT i will purchase another for my wife

Great i work an auto auction use daily lots

Worth the buy, trust I over research way too much and this actually worked.

I’m sure it will work I

I read reviews and watched review videos and with so many favorable I went ahead and bought one

ugggI’m going to miss this guy
