I just purchased my first car, and I figured that if I could afford a car, I should probably pick up some ’emergency on the side of the road gear’. It’s one of those things where like, if you have it on hand, you’ll never need it. But if you don’t have it, you’ll have problems and regret not having one. My car is a 1.6L, so I figured the GB20 would be just fine for the job. I also have a couple of ride on mowers. One doesn’t have a battery in it at the moment, so I hooked this up to the leads and it started up just fine. I always carry around power banks for my phone, so having one that can jumpstart all of my engines is super practical! Super portable!

I spent 2 days looking for someone to give me a jump start and had no luck! I called a friend he told me about these things and I ordered one immediately and it arrived the same day, I charged it and read the guide on how to set it up and boom my car was back running again. 100% worth it I always keep this in my car now in case my battery ever dies again

Already used the NOCO Boost Sport GB20 500 Amp two times, including one time when the battery was truly acting dead. Easy to use and works really well. I especially like the safety features for family members who are not super high tech.

I bought this in the event that I have a dead battery and my girlfriend seemed to think I was a weirdo, as she always does when I buy something in the event that “well some day I may need it!” Today she went down for work and her car wasn’t starting. She started her melt down and after a few minutes of tinkering, I said “let me try this”. I slapped it on and within 10 seconds her 2019 Jeep Cherokee was running again. She ate her words lol I clipped the negative terminal to the post, then the positive to the post. Turned the machine on, and her car immediately started. And this isn’t a one time use, after I took it off the battery on this thing was still fully charged according to the LED bars, so I left it in her jeep in the event that this happens again soon. 100% worth the money, and I’ll be buying family a few for Christmas gifts.

We use it when traveling or for an event it lasts a very long time and charges our devices well. Also use it for car jumps. Works great, best gift

Great to have in a pinch

I bought this in case the battery on my Harley dies, which it did. It fully charged in about 3 minutes. It’s lightweight and I can fit it in a saddlebag in case I need to bring it with me for a long trips. It also works as a charger so you can plug your phone or other items into it
Just fine –
Even though this is “rated” for 2.0 liter engines, it has jumpstarted my 6.0 liter Chevrolet engine multiple times on one charge. I think it would jump almost any modern car with a gear reduction starter regardless of engine size. Cars from the 80’s and earlier might be harder to jump start. Comes in useful as a USB charger and flashlight during power outages. Small enough to keep somewhere in your car.
