NOCO Boost GB20: 500A UltraSafe Jump Starter Power Pack – 12V Car Battery Booster, Portable Power Bank & Jump Leads - For 4.0L Petrol Engines

Car had a dead battery , Not for the first time as I barely use it. Bought this and it arrived the next day, despite not being a prime customer. Jump started my car without me having to charge the device first. It was really simple to use. I am really impressed with it. Only downside was the charging cable, I did not have a plug to fit it, But after a rummage through my cable stash I found one that fit it which had a usb end so I can charge it. Overall a very handy little device to have.

small, light and compact. so easy to keep in your emergency bag in the back of your car. looks and feels like a well made quality product. came out of the box nearly fully charged so I have no idea how long ago it was made but by all accounts they hold a full charge for around 6months. charges with USB C and comes with a cable so can be charged in the car on a long journey. good value during the Black Friday deals. good peace of mind having it in the boot going into winter. cold weather kills batteries.

Great product. So far jumped started 2 cars with completely dead batteries (1 car 5 week off roads the other was 5 months). Noco cannot even detect the battery (no chase light). So I pressed manual override, lights on the gb20 started chasing/moving. And as soon as I press start engine or turn the ignition key to on. Car started immediately. Worth item to have on your arsenal at all times.

This is the second Noco Boost GB20 I have had. My previous one failed after quite a few years - the on/off button stopped working. This one works fantastically on my little Micra battery to start it, when it is flat. I do not use my car a lot and white it is sitting on my driveway the battery loses power. This tool is a real boon. The only flaw with this new GB20 is that it did not come with any instructions, only a thick warranty booklet in many languages. This is fine for me, having had the same before because I know how to use it safely. I think it would be a definite problem for a new user, though. I can't understand why no operating details are included. I would have given five stars for this unit, however have only given four stars for the lack of instruction manual. The current price is fair value for money, in my opinion.

Essential piece of kit. Simple clear to use.

After trying again, I was able to get the device working to start my car. I suspect that there wasn't a good enough contact when I first tried and despite this, all signals seemed to indicate the device would work correctly. On my second attempt, I pushed the connector hard into the device and was able to get it a little further in with a lot of resistance and I also wiggled the clips around a bit on the battery terminals to try to get a better connection. This time when I turned the device on, I could hear it ticking occasionally and then I was able to start the car. Old review: Bought this so I could get my car to the repair shop for a replacement battery but it was not able to start my 2015 VW Polo 1.0L. NOCO customer support advised that the NOCO Boost GB20 I purchased must be faulty because it wasn't starting the car despite all indicators on the device being correct. Back to old faithful jump leads!

Haven’t used it yet but the quality build gives me confidence. Extremely well made with high quality accessories. Packaging was quite superb and the actual box the product was in was professionally made and printed. Uses a standard USB C lead for charging so compatible with most peoples homes

Bought this to keep in my motorbikes as I do European trips. It will easily start a dead batter on a gtr1400 and a pan st1300. Also tried it on my 2.8d motorhome totally dead battery and it started instantly. So it's a good buy. People who have said it didn't work after sitting for a year etc, remember this is also a battery so you need to pop in on charge for an hr every few months or it will reduce in power like any other battery operated gadget. Also stick in on a dead battery now and again so the cells have to work in it.

Va bien para arrancar batería de moto BMW F 650 GS de 2012.

High quality product!

I bought the NOCO Boost GB20 as an emergency jump starter for my 2.5 L gasoline sedan, and it has exceeded my expectations. The unit is compact, easy to store in my trunk, and very straightforward to use. the clamps are easy to attach, and the LED indicators make operation simple. One cold Alberta morning when my car battery was dead, I connected the GB20, waited about 30 seconds, and my engine started immediately. It holds its charge well, even after sitting in the car for a couple of months, and also works as a USB power bank with a built-in flashlight, which is handy in emergencies. The safety features like spark-proof clamps and reverse-polarity protection give extra peace of mind. My only minor issues are that it is micro usb charging, and the 500 A rating may not be enough for larger engines or diesel vehicles. Overall, for compact cars or mid-sized sedans, this is a reliable, portable, and versatile jump starter that I would recommend for anyone looking for emergency car battery support.
