    • Compact and Reliable
The NOCO Boost Plus GB40 is a must-have for any car owner. I got tired of waiting hours for roadside assistance to jumpstart my car, so I researched and purchased the GB40 model. I found the owner's manual on the NOCO website to learn how to use. It’s compact, reliable, and easy to use. In addition to being a jump starter, it can also charge a phone and works as a flashlight. I purchased the carrying case separately. Great value! ... show more

    • Perfect unit for my hybrid Honda CR-V
I’m out of town for months at a time. Therefore, every time I return home, my battery’s dead. I was concerned this would not be strong enough to start a hybrid, but it works like a charm. The unit is small and easy to use. The one thing I will advise: on a hybrid the battery is often too dead for this unit to recognize it’s connected. You have to override the sensor for it to actually jump your car. ... show more

    • Works instantly everytime!
This is the first jump starter I ever owned and it has saved me from having to deal with headaches every time I have used it. I was having intermittent alternator issues on a V6 dodge and my battery die every now and then. This started it up right away on the boost mode and even gave the battery enough charge for me to get where I needed to go (short distances). The charging speed could be better but that's really a non issue. The design is compact and feels well made. Highly recommend ... show more

    • Highly recommend this! It’s easy to use and dummy proof
Ok everyone who owns a car should own this. This jumper is AMAZING. I am not a car person at all. I’ve never jump start a car before despite having multiple dead car batteries. This product is seriously dummy proof. My only complaint was that I had to come back to the product page on Amazon to find out how to work it since the instructions wasn’t in the box. Other that it was extremely easy and works! You just have to add the clips to the battery (red +, black -), power on the jumper, then turn the car on. Thats it! Highly recommend! It took about 15 minutes to fully charge the jumper before using. And the jumper is so small that it can easily be stored in your car! ... show more

    • Works surprisingly well for the size and price
I keep this jump starter in my old truck and have used them several times for myself and others - size and weight are impressive - definitely an improvement over the big lead-acid jump starter days !!! also has a USB charge port to power other devices - can't really speak to battery life or longevity of the unit, but so far so good ... show more

    • Overall not a bad product
Why did you pick this product vs others?: I picked this product over many others. Due to several factors. It's cost effective, very small and compact, easy to use,l. Charging capability: This product charges quickly and easily after charge. I store the product and haven't had to charge it for at least three months. Start-up: Starts up.It's simple as hitting a button. Jump start: Jump stocks my car ten seconds. Size: Small and compact. Value for money: This product's a good value for the money. Speed: Only took thirty seconds or so to stop my car. The only downfall to this is I wish they would have made it would better charging cables. If your battery's completely dead, this product's not going to start your car. The thicker cables, what about equality?You'll get.We're trying to start a battery.If it's dead. ... show more

    • Excellent jumpstarter that's worth the money.
This is a FANTASTIC jump starter. I don't drive a lot because I work from home, but recently had a chance to test this, after unwittingly draining my Murano's battery while installing some in-channel wind deflectors and using the power on AUX mode. Despite this having only one power bar, because I'd not charged it since I bought it two years ago, it still started my vehicle lickity split. My Peak jumpstarter that was fully charged? Didn't do squat for the battery. This is a great security to have in one's car and doesn't take up much space in the trunk, or under the floorboard of an SUV trunk area. Would absolutely have faith this would start a much larger SUV than my Murano with ease. After having work on low juice, I bought another slightly larger one to keep at home and replace the useless Peak jumpstarter I've now recycled. ... show more
