FAQs
What do I need to bear in mind?
Before you buy a booster, you should check that it’ll work with your engine. The bigger your engine, the more power and a bigger car battery will be required for it to work. Our picks will cover most new cars, meaning you’ll have peace of mind with one of these, but there are boosters designed for bigger engines. It’s also worth mentioning that some of these boosters will not work with cars fitted with Stop-Start. If you need a general guide, check out our picks for the best car batteries.
What other features should I look for?
Aside from charging your car’s battery, there are a number of useful features that you should look for in a portable battery booster. Look and see if it has a torch, most do, and it can be invaluable if you’re stranded at night. If you suspect your car’s battery might be at a low point, it will be worth investing in a battery tester.
Also, look for USB charging; this means you’ll be able to plug your phone in and charge it up. Again, a great feature if you’ve broken down and your phone battery is low. And if you need to assist in someone else’s breakdown, having a set of jump leads in your car is a useful accessory.
