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

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.

I literally never write reviews but this thing is so perfect and exactly what I was hoping it’d be that I had to give it 5 stars. I bought a Honda CBR600RR and as I park it on the street I decided to install a GPS tracker on it. Works great but if I don’t ride the bike for a few days the battery will be completely dead. (I’ve probably installed the tracker wrong, I have zero mechanical experience, which should be another plus point of how easy this battery pack is to use) Battery kinda dead: you hook it up to each terminal with the supplied clips, turns on instantly. Battery completely dead: there’s a safety feature that won’t let you press the boost if it can’t detect a battery, if you know it is hooked up you can just override that by holding the button and bam, works instantly. I’ve had to do both a couple times and honestly it’s so easy. One of the most spot on perfect products I’ve ever bought. I carry it in my backpack when I’m riding just in case I need it. It’s so easy to use. It takes me longer to undo the screw on my seat to access the battery than it does to turn the bike on with the battery pack. 5 stars but I’d give it more if I could. Also I charged it to full power when I got it as instructed and it’s started my bike multiple times so far and I’ve not had to recharge. There is a battery indicator so you’d know when it needs charged anyway.

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.

I have a car with an intermittent fault which means I'm never sure whether the battery will be charged or flat. Most of the time it's fine but, every now and again, I find that it's just dead. An auto electrician has said that I need to leave the car with him for about a week so that he can test it every day. Presently, I can't do without the car for a week. He's done a couple of checks but could find no fault. That's why I carry one of these. The previous one got hot in the car (remember the heatwave?) and swelled so I had to dispose of it. I've had this a couple of months without needing it but was very glad I had it when I went to the car to find it had no power. The central door locking didn't work, the dash lights didn't come on and everything was dead. Luckily, I had connected this unit to the mains for about six hours when it arrived to fully charge it. I connected up the booster, remembering to switch it on, turned the ignition key and the car started first time. I was impressed. Even more so when, after a short drive to get fuel, I found that the car still didn't have enough energy in the battery to start. I connected the unit up and it started easily for the second time. My car has a 1.4 litre petrol engine. I checked the remaining power on the colored LED display and the green was still lit, indicating there was more power immediately available if I needed it. It was a little costly but very effective and gives me complete peace of mind. Overall, I'm happy with my purchase.

Worked perfectly. Highly advise to read the instructions (you need to scan the QR code on the booklet provided to see them). Battery unit itself is very sturdy and looks to be at least splash resistant to a degree. Used to jump start my car and worked immediately. I would call out that the jump leads are not as long as I anticipated. Not a problem for me as my vehicle has a small engine bay, but for those with larger vehicles where the battery is in a accessible location and the manufacturer position jump start points in the engine bay with positive and negative far from each other, the leads MAY not reach. A very niche scenario but can still happen.

This looks a well made item that will hopefully start the car if needed. I have not needed to use it yet so I can’t say how efficient it will be. I have had it about a month and the battery charge is still full so I will check it again in another month and hopefully it will still be full.

Brilliant bit of kit 5 stars 🌟

Good quality build and easy to use. It is one of those purchases you debate about buying -"but will I ever use it?" - and then one morning the car/van/motorcycle won't start because the battery doesn't have enough charge. If you have breakdown cover inevitably you are in for a wait, if you don't there will be a garage bill to come out and start you (unless you have a helpful friend who also happens to have jumper leads). With one of these you can be started and on your way in a couple of minutes. Just remember to occasionally put it on charge as it defeats the object if you've let this go flat and have to wait for it to charge before you can start the car.

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!

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!
