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

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.

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.

As many other reviews have said, this is a well made, compact and lightweight booster pack that works extremely well. Honestly for the purpose of the occasional jump start it’s great and the connection cables and clips are very well made and the body of the pack itself seems extremely durable. The additional features of work and emergency SOS lights are also great. The only thing I cannot understand is why they used a micro USB plug for the charging input port. Micro USB is really out of date now, it can only be plugged in with the plug in one orientation, and in the dark it is hard to see this and they are known for being weak and easily damaged. On top of this, they have a very limited charging current which means the pack is slow to charge. Frankly this should have been fitted with a USB C socket to make connection easier, faster to charge and far less likely to get damaged. Otherwise, it’s a great device.

GB 20 review. Bought this as I have been using a cheaper unbranded unit , which failed to charge. The GB 20 is a solid bit of kit , used on a 1100 cc motorcycle and 1ltr car. The only issue I have which I don't think people have mentioned is that the light is easy to knock on by mistake when it's in the case , in the glove box it was repeatedly getting switched on , I noticed on several occasions when driving home in the dark the torch 🔦 on in the glove box. It's now in a hard case in the boot which avoids this happening. It's worth the money and always handy, even if you never use it .

This is an amazing and highly reliable product. Have used it multiple times. Needs two people to operate though.

It seems to be a universal rule that cars only ever break down when it is difficult to get anything done about it. I needed to use mine for a short trip on Christmas day. After clearing ice off the windows, I got in, turned the ignition and nothing but a clicking noise. No one available to help, so I was unable to use the car that day. Thinking on the problem, I realised that for the past few weeks I had been using the car for work with the lights, heaters, dashcam, satnav and radio all on, followed by 5 days of only using the car twice for 1.5 mile trips to the local shop. Having intended to buy one of these boosters a while back for emergencies, I ordered a NOCO Boost Sport GB20 from Amazon (the cheapest NOCO model because my car is only a 1.2 litre, so well within the specified "up to 4 litre" range. The product arrived promptly, but unfortunately comes with only about 1/4 charge. The manual says to fully charge before use, which I estimated at 3 hours given the USB charger I was using. After the 3 hours were up, I clipped the leads to the battery, turned on the unit, gave it 30 seconds, crossed my fingers and then turned the ignition - it started first time. I ran the engine for 15 minutes and will try the car again in the morning when I can give it a good run without needing the headlights on. If it doesn't start again then I have the booster ready in order to get it started and get to a garage for a new battery. I really wish that I had bought one of these a year ago (as I was going to do after helping a work colleague jump start his car). From now on, this is going in the boot of the car and coming out every weekend for a recharge, just because it will give me peace of mind. Compact and very easy to use. Really pleased with this purchase.

My car is less than 3 years old - 3 weeks ago, the battery failed and I had to call the AA (being an automatic, getting someone to help me bump start it wasn't an option) as I was not at home at the time. Having then done a 2 or 3 longer journeys, it was a bit of a surprise to me when it failed again last week. I felt a bit off about calling out the AA so soon after my previous breakdown, so decided to get the jump leads out and deal with it myself. Except my jump leads seem to have gone walkabout. So that decided me on getting a battery zapper. However, many of the products I looked at had mediocre reviews to say the least. As a person with disabilities, I need a product that I can a) carry without too much difficulty and b) won't let me down when I actually need to use it. So, I decided to spend a bit more than I'd originally budgeted to buy something that didn't weigh almost as much as a car battery itself and had better reviews. The zapper duly arrived 2 days later and having charged it (it took about 3 hours to charge fully from my laptop) took it out a couple of days later to get the car started. And it took me longer to read the instructions than it did to get the car started. The crocodile clips are seriously sturdy and it took me a bit of time to actually get them attached to the battery at the relevant point, but my car started in 30 seconds or so. And I'd barely touched the charge in the power pack. The pack itself has some useful functions and I was waiting on a power cut over the weekend so I could test them out. The USB port for charging other electrical items isn't essential for my needs, but it could come in handy. The torch on it is seriously bright, there would be no chance of a person not being able to see using it. The charging cables are short, but it turns out that they're long enough to do the job required. And the pack doesn't weigh so much that I need to use 2 hands to lift it - something that has to be taken into consideration when one isn't very strong. The only thing that lets it down is the nasty nylon storage bag that comes with it. However, I'm sure I can make a better cover for it, in time

I've had this for a couple years. Worked well on my car and also on my riding lawn mower. Works so well I got my sister one and she loved it. She found it easy to use and it saved her a few times.

High quality product!

Great piece of gear, goes everywhere, fits under the seat of my motorbike and I have a bigger one in the 4wd, take them everywhere with me. I have been able to help so many people, more convenient than jumper cables.

Es muy buen producto lo compré para mi Suzuki Jimny 2023 de 3 puertas, funciona muy muy bien.
