Best Jump Starter Overview

Your car’s engine size and whether it has a petrol or diesel engine will determine which is the best jump starter for you. Therefore, to determine if a jump starter is suitable, all brands will state the device’s compatibility and most are suitable for jump-starting 2 to 10-litre capacity engines.

Below is a list of the best car jump starters that are suitable for all petrol and diesel powered vehicles in the UK.

The advanced design of this jump starter means that it’s ultra-safe to use, which is thanks to features such as spark-proof technology and reverse polarity protection. It also has a “mistake-proof” design that safely connects to any car battery.

How We Rated

Whether we need to jump start our own cars or be the “hero” and jump start our family or friends’ cars, we have multiple jump starters to choose from. The NOCO Genius (which we rated as the best in this article) is our favourite to use but we also own other jump starters that all have their practical uses.

To keep up our commitment to reviewing and testing the latest jump starters (for this article), we upgrade and test multiple models each year. With regards to our testing, we test the jump starters in a range of scenarios as well as on multiple cars. For example, in the images below are two “testing” uses of the NOCO jump starter. We state “testing” because we used it to jump start (successfully) a car in the snow as well as a 6.2-litre V8 Mercedes AMG.

Below is a video that we posted on our YouTube channel that shows us testing the latest TOPDON jump starter. This involved jump-starting a completely flat (as demonstrated in the first few seconds of the video) 3-litre Mercedes diesel. As you can see in the video, upon initiating the jump start, the car fired up straight away.

As well as our testing and experience of using a range of jump starters, we also based our recommendations upon hours of research and several factors. Some of the factors that we took into consideration included the peak power rating, number of jump starts per charge, quality of the clamps and device, ease of use, safety features, warranty, additional functionality and value for money.

Conclusion

One of the best investments that you can make to get you out of a sticky situation is a car jump starter. Not only are they a lifeline if you ever have a dead battery but they also offer charging for all your accessories on a road trip. All of our recommendations are suitable for all budgets and include both lithium and sealed battery-powered options. However, we would personally recommend lithium devices because they offer more benefits than sealed alternatives.
