Better then the old school cables

Works really well! Light weight. Easy to use. I love the storage bag it comes with. I’ll be getting another one for our other car & one for my mom just in case! 10/10 Read more

Life Saver – Easy, Reliable, and Worth Every Penny

Jodi BowmanJune 16, 2025✓ Verified purchase

I’ve used the NOCO Boost GB20 twice now, and both times it saved me from what could’ve been costly and time-consuming situations. Instead of calling a tow truck or waiting around for someone with jumper cables, I was back on the road in minutes. It's incredibly easy to use—even if you're not mechanically inclined—and it holds a charge for a surprisingly long time. I charged it once and it sat in my car for weeks before I even needed it, and it still worked perfectly. Recharging it is quick and hassle-free. This jump starter has already saved me money and time, and it’s given me peace of mind knowing I have a reliable backup in my glove box. If you drive a gas vehicle (up to 4.0L), I highly recommend this. It’s compact, powerful, and an absolute must-have! Read more

Worth Buying

EveFebruary 25, 2026✓ Verified purchase

I have a Honda Fit. I hooked this to my battery and it started right up. What it didn’t tell me and I didn’t know but I found out from reading is once your car starts, you need to drive it around for 20 to 30 minutes to get the battery and the alternator charged up. I just want to say this was well worth the $79 I paid. I will keep this charged and keep it in my car just in case I ever need another charge. I would recommend this to anyone. If you are taking a trip at night, or even during the day, have it charged in your car. Can also charge your cell phone with it. Read more

Purchased in 2021 and still going strong. Bought a higher version in 2025 for a family member. Pros: Holds a charge for a long time, has been used on several occasions, and doesn't require immediate recharging. The included clamps are compact and rugged. It starts engines far bigger than recommended, though slowly (powerful enough for small engines). The safety features and ease of use are appreciated. Cons: The charging speed for phones is slow. The included bag is flimsy. I'm a proud owner for years, I bought the next model up to start larger engines. I've helped other drivers with off-brand jump starters that are bulkier on several occasions. This relatively compact model has surprised me firing up diesel engines larger than it's rated. A must-have for every driver, and cheap enough to justify. Read more

Compact jump pack

Steven Z.March 2, 2026✓ Verified purchase

Longevity remains to be seen as I've only had this about a week, but so far its been stellar. My FJR1300 was having some battery issues so I wanted something compact and durable I could keep in the panniers. Picked this up, and it's been working great. Charged quickly and easily, started up my bike multiple times without needing a recharge, and just feels well made. The flashlight has also been useful, and its nice to have the flashing if I ever get stranded roadside. The only two minor gripes I have that bump it to 4 is that the carry bag really needs a drawstring toggle to keep it closed, a few times the jump pack had slid out in transit, and secondly though the flashlight is very useful I wish it didnt look like headlights 100yds away, from 10yds away. Especially as a biker, I dont want to give the impression that I'm both a car and way further away than I really am if I'm using the light on the roadside. If neither of those bother you, then I'd recommend it. I also had reached out to NOCO about some of their other products and they were responsive and helpful, so it's good to know there's actual company backing behind the product, its not just repackaged dropshipped garbage.

Device works exactly as described

AnthonyJanuary 2, 2026✓ Verified purchase

Bought this thing a month ago, charged it fully and kept it in the trunk. Woke up today to a dead battery in single digits temperatures. Rushing to go to work with no time to waste, this little beast started my truck in a single start. Gave it 5 stars for keeping 100% charge through a month of freezing temps, and for working in a start despite the battery being fully dead. It still showed fully charged even after that use.
