The last thing you want to do when you get a puncture is use your car’s emergency wheel changing jack. They’re basic to say the least, and can be hard to get to grips with. But there is an easier way – buy a powered jack. It could be the difference between changing a wheel quickly and safely, or enduring a long, potentially dangerous wait for help.

The five products tested here also enable drivers to stand back from the vehicle as it’s being raised and lowered, reducing the chances of a nasty accident. They can even be used to level caravans at a camp site, lift the hitch of a large trailer to the tow ball or, of course, for working on your vehicle at home.

Our electric jacks all weigh at least 5kg, so you should take care if storing them in the boot to ensure they don’t bounce around in an accident or if you stop suddenly.
