Alternatively, if you require a heavy-duty jump starter that’s still portable, the Clarke 4000 is the best option. It’s been built with durability in mind and has a peak power output rated at 2,000 amps.

To rate the car jump starters within our roundup, we based our recommendations on thorough testing, our experience of using multiple types, the latest 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.

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 Best Jump Starters

1. Best Overall: NOCO Boost HD GB70 Portable Jump Starter

By far the most popular car jump starter in the UK is the NOCO Boost HD GB70, which is a compact yet powerful lithium jump starter. According to the brand, it’s able to perform 40 jump starts on a single charge and it’s rated for petrol engines up to 8 litres and diesel engines up to 6 litres.

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.

If you are on a tight budget but still want the features of this model, the brand also offers cheaper devices that are less powerful. For the majority of car owners, the lack of power won’t be an issue, which makes it a great option to consider.

2. Best Heavy Duty: Clarke Jump Start 4000 Booster Pack

An alternative to a lithium jump starter is a sealed battery unit such as this Clarke 4000 power pack. In terms of its power, it has a peak power rating of 1,500 amps, which is ideal for starting petrol engines up to 6 litres and diesel engines up to 4 litres. It also features heavy-duty leads and clamps which makes it ideal for tough environments such as garages.

A standout feature of this particular jump starter is the fact that it weighs 17 KG, which is a clear example of the quality battery it uses. The brand also states that the battery is maintenance-free and designed for a long service life.

  • Peak power of 1,500A
  • Heavy duty 1 metre long leads and clamps

Overall, the Clarke 4000 is a robust car jump starter with a heavy-duty design that’s ideal for storing in garage environments. It does come with a premium price tag but it’s built to last and it certainly won’t disappoint.

The main drawback is the expensive price tag attached but when you consider its very impressive performance along with the reputable brand backing, it makes it a great investment that certainly won’t disappoint

4. Best Budget Lithium: GOOLOO 1500 Portable Car Jump Starter

If you require an affordable, compact and very portable jump starter, the GOOLOO pack is a great option to consider. It has a peak output of 1,500 amps and it’s suitable for starting petrol engines up to 8 litres and diesel engines up to 6 litres.

5. Best Budget Booster Pack: Sealey Road Start Emergency Power Pack

Another heavy-duty jump starter pack that instead comes at a more affordable price is the Sealey Road Start. It’s an easy to use device that offers 900 amps of power for jump-starting petrol or diesel engines up to 2 litres in size.

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.


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.
