NOCO Boost GB20 500A UltraSafe Jump Starter, 12V Lithium Battery Booster

I bought this to avoid having to ask for a jump when my battery died. Great investment! I can use it to charge my devices when not using it for my vehicle, it portable so I can take it with me, very durable, easy connectivity, quick charge and includes jumper cables. As a single Female, I highly recommend it for the Ladies!

Two of our car batteries died within a month of each other, and what was a nightmare trying to jump-start the first car with another vehicle turned into such a pleasant experience with the second one. This device is a lifesaver! It’s incredibly easy to use, and honestly, I feel like I could do it on my own next time without asking my husband for help. That gives me a lot of peace of mind. We were expecting the worst because we had to unlock the car with the key the day before while trying to figure out why it wouldn’t unlock with the remote. I guess that set off the alarm and caused the lights to keep blinking, even after we set the lights to the “off” position. We figured the battery would be completely drained by the next day, when we could take it to the mechanic to replace the battery. But today we connected the device, let it sit for about two minutes (just in case), and the car started immediately! When I brought the device back home, it was pretty drained and showed only one bar, but I’ll recharge it and keep it ready. It also has a very cool light and works as a power bank for devices. I’m buying another one as a Christmas gift for my sister!

These products are always fairly expensive, but they are worth the purchase. It is a lot better than using jumper, cables, and a lot safer. It is also easier, not having to rely on another vehicle and they work as they should as far as jumping a vehicle and also charge his phones and electronics.

Must have for just about any driver any age. Durable, affordable and easy to use. So much better than the scary days of jumper cables. Bought one for each of my adult sons- nice Christmas or bday gift.

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.

I have bought three of the GB20 devices over the last seven years or so. All have been helpful, usually for other people and occasionally for myself. One a friend borrowed and lost. The other two continue to serve well. While I recharge the devices once a quarter, they still have plenty of charge before I do. I would buy another, but in my Alfa Romeo 164 the positive post and the ground point are too far apart for the supplied cables to reach. There is no option for longer cables.

Great product quality

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.

Jesteśmy zadowoleni.

Purchased for personal use but ended up using it for work, never thought it would be as good at it actually is. outstanding little jump pack small and compact light weight Been using it for 18 days approximately jump starting various sized batteries ranging from 420 amp up to 760 amp no problems at all. Have to charge after approx 5 jump starts highly recommended for the price.

Fantastic bit of kit. Got it for a quad and ride on lawnmower that have dodgy batteries that don't charge too good. Works perfectly.

High quality product!
