this little device is powerful

This device is fantastic.

Most of the 1 star reviews are from defective devices which happens with any electronic device

Now I have a new battery, and a device to jump start said new battery when it dies.

Awesome device!

This very portable device jumped my midsize truck 3 times on a single charge!!

Works well, charges devices and has jumpstarted multiple 4 and 6 cylinder cars

Works well, charges devices and has jumpstarted multiple 4 and 6 cylinder cars

A life saver and a very good device.

It's a fantastic device and has not let me down

This device has worked great, used it on a mower, a golf cart and just recently my full sized pickup that had dead battery in -20 degree temp

during the winter need a good device to jump cars.

Great device have used it 3 tienes in a single charge and its still full

This little device is amazing

Perhaps this device will work if a battery is drained from leaving a light or radio on in the vehicle, but once a battery has gone bad after about five years, this device will not work.

This device is truly a life saver!

This is a cool little device, with a number of thoughtful design features

Super great device!

The device charges from empty fairly quickly as well.

This device is excellent!!

These devices are even capable of multiple jump starts on one charge so no need to rush to recharge it after one use.

This is a very cool little device

So I used this device and it worked like a charm

Compared to chargers I grew up with, this is an amazing device.

This device is a life saver

I consider the device without a hard case "not portable" since it could easily turn on be become dead through transport.

know if I received a faulty product but the device

Fantastic device, jump started my 2019 Altima when it was having battery problems

Great device that has come in handy multiple times.

My parent's car needed jump started recently and this device was very easy to use.

This is a great device that's easy to use

Highly useful device

I couldn't believe how easy and how powerful this little device is

Great device

this device works great but the clamps need a to have be a little longer lead.

It is a good and small device that is ready when you need it.

Very reliable device

This is a solid well built device.

Amazing little device, started my car right up!

Unfortunately the device failed to charge after 1.5 years and minimal usage

Great device for anyone to have one of best investment in my toolbox

Great device for jump starting a car.

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

Great device - only hope that I never need it.

The unit is so small you can also take it to the beach to charge portable devices with the USB connection

I highly recommend this device

It comes with a very cheap drawstring bag which is disappointing given that it’s such a nice device

I attempted to jump start a 1400cc Suzuki motorcycle and the device was not effective in that effort

I dislike this device when it comes to cold weather because it fails to charge my car I waited more than 1 hr and still nothing even if I override it, it’s still no good

This little device works like a trooper once fully charged it turned on my daughter's dead car

This device will do that although I was a little surprised at how much it drains the device

This device is a lifesaver

This device is amazing

I definitely recommend this device to those who use campers or go on long trips in case something happens and nobody can jumpstart your car

In summary, while the NOCO GB40 booster did provide a noticeable start assist - better than my 100A AC-powered starter, and impressive given the unit weighs just over 1 LB - if I can't count on it to start the car when the battery is completely dead, the device is useless

I know you are not supposed to store this in the car because these devices lose a lot of their cranking power when frozen.

The device is easy to use, compact and does EXACTLY what the manufacturer says it will

Very handy device to have especially when I go out

Perhaps this device will work if a battery is drained from leaving a light or radio on in the vehicle, but once a battery has gone bad after about five years, this device will not work.

Excellent device I recommend this item very very highly !

After a couple years the device has lost most of its capacity and doesn’t work anymore

I also used it to charge our mobile devices when we lost power for 2 days due to the hurricane

At 1000 amps, and in such a portable device, this thing has saved me and a lot of my friends as well

I love this device as it started my car multiple times but today was just not all that good

Also it has safety features to protect against overheating the device, AND an override that turns off the safety if your battery is very dead (use with great caution!)I live in the Sonoran Desert where wide temperature ranges tend to make car batteries short-lived and they die suddenly

A handy device to have on our ATVs and snowmobiles!

It lacks the ability to charge itself via USB-C, like most devices do these days.

Good device to keep in your car.

This device was a life saver.

Great device.

I suspect that this is a good device, just not for larger diesel engines.

The device is cool, well made with good features etc.

Looks like after use to jump dead battery device still shows FULL

Surprised how capable this device is for it's size.

I attempted to jump a vehicle I routinely have to jumpstart in my yard with no success, plus the device indicated a fault after the first attempt

This item was a life saver as I would've had to use roadside assistance to get me from A to B. Great device and after 4-5 jumps was still on full power

I highly recommend this NOCO device.

It is the perfect size too instead of the other bulky and cumbersome devices you’ve seen.

Since repairing the starter this device has worked great and a jump start, battery back up, and I also use it to just test 12v dc devices prior to wiring them up to my boat/truck.

Very convenient device to keep in the car, especially for car audio fans

Very nice and handy device to

I have had this charger for a few years now and, while I've been impressed by both the build quality and the jump start capabilities of this little thing, the device's longevity has been unimpressive

This week I helped a stranded lady jump her car with this when a weaker device failed

This little device has been a lifesaver

I love how easy this device made it for me, a woman who has never jumped a vehicle.

Great device, handy, compact, charges our devices too if not home.

Great device absolutely worth having gives you peace of mind knowing you can jump yourself or a friend in

Fantastic device

Thanks guys for such a cool compact device that could be a life saver

I love this product because I have a mid-sized (40hp) Kubota tractor on a remote piece of property and instead of removing the battery ever winter, I just take this device with me during the Spring to get it going again for the season

This device was so easy and quick to use

But this little device has no trouble at all with that!

I like everything about the device (size, convenience, time it holds is charge, etc.) but all that is worthless if it doesn't do it's one job

The Noco GB40 is a good device, with simple connections and quality materials

What a great little device to own and carry with you in your car

But use this review as a barometer: as long as the battery can hold a charge, this device will work.

Nice device

Awesome little device, everyone should have one for those just in case moments.

and I didn't need assistance, and I felt safe using a device like

I used it for a Kia Picanto, the device only worked once.

I highly recommend this device and think everyone should have one in their car in the case of an emergency.

I love this device; so much that I have purchased 3, 2 of them as gifts to family

With this tiny, magical, incredible device, we jumped the battery and were running within minutes

Most of my day is spent on the road so this device is a lifesaver for me

Great device for no start low battery emergency

all is well now that I understand how to use this amazing device.

it simply works :D

Already used it once really worked great!d

Returned this product for the Audew which spins my V twin like a top.

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

would click off a few seconds after just a couple seconds of slow c ranking

USB C is much faster, if this model is available with a USB C charging port I would like a replacement...
