Portable power packs are fast becoming a workshop must-have, because they can now be used for a range of jobs beyond starting your car.

Of course, their first aim is to revive  an ailing battery without the need of jump leads or friendly neighbours. But extra sockets and tools, including compressors and lights, mean they can perform tasks such as checking tyre pressures without the need for a lead to your cigar lighter.

In fact, many have their own 12V power sockets, which can be used for cool boxes or tools, while some now even include USB outlets to power or charge electronic gear. So which of these versatile boosters is best for your boot or workshop? We hooked up 10 to find out.

The Test

We logged the spec of each pack, noting clamp size and insulation, accessory sockets, lead lengths and weight – key for a life on the move. For safety, we  prefer units that isolated the battery.

Once we’d charged each product,  we used them to start a 1.4-litre Renault with a flat battery. Where applicable, we timed the compressor blowing up a tyre from 20-30psi and checked the gauge.

Verdict

Chain store giant Halfords retains its crown – for the time being, at least. But it was run very close by the RAC Power Station, and a price adjustment to the latter could easily tip the balance. The Clarke Jump Start JS1010 performed well enough for a podium spot, yet lost out to the top two on features.

Far to Expensive

When battery goes on these all the rest is disposable as replacement batteries cost more than some units, I have 4, first a Clarke it lasted 2 years, then a Netto which lasted less than 2 years with compressor, both suffered battery failure. I bought 2 Rolson compressor ones from Maplins at £19.95 each to get free delivery, they are still going strong at over 44 months old, I don't use the charger supplied now I charge them with my Aldi digital car battery charger I think this may be helping keep batteries good. I would rather have a box with a battery and a pair of separate jump leads in lid, will have to make my own like I did for caravan years ago if Maplins stop selling them for less than price of the battery in it. These are not green products as they get dumped when battery dies, what a waste.
