Portable power pack reviews - 2013 group test

As drivers rely more and more on electronic kit, it makes sense to carry a portable power pack around in your boot.

These devices are designed to start cars with dead batteries, but they can also charge and power everything from music players to cool boxes via a 12V socket.

Some also have USB outlets, doing away with the need for adapters, while others offer household mains power. 

Built-in air compressors are common, too, making a portable power pack ideal for pumping up tyres in an emergency or blowing up inflatables away from the car when you’re on holiday.

So which is the one for your weekend breaks this spring? We charged up eight.

How we tested them

Versatility is a central part of a power pack’s appeal, as they need to do more than just start cars. So we looked for a selection of sockets, and gave extra points for compressors and lights.

We also wanted long leads, large clamps and some way of cutting power to the cables for spark-free battery connection, as well as a warning facility if they are fitted incorrectly.

Weight was another factor – these devices are meant to be carried round – plus we factored in price, excluding delivery.

To check battery cranking power, we assessed how each turned over a 1,300cc engine.

Verdict

Revised version of Halfords’ Powerpack 200 just hangs on to its crown thanks to its well judged balance between price and performance.

If you want something with a bit more cranking grunt, go for the similar Ring RPP225.

Sealey’s Roadstart takes the final place on our podium, and is a good option for buyers on a budget.
