About this deal

The JSM400 Jumpstarter is supplied with a zip fastening bag, AC battery charger, smart charging cable, switch cable, 3 way USb cable, car charger adapter and 8x notebook adaptors. Many modern cars will have sophisticated LED headlamps, which have taken over from the equally bright xenon lights, which were popular on upmarket models a decade ago. But drivers of older and less expensive vehicles will still have to put up with the traditional halogen bulbs on at least some of their forward-facing lights.

We tested Muc-Off’s HCB-1 and it did a good job of warding off corrosion for several weeks, or Ferrosol’s UB products will provide longer-term protection. Multi-function charge and start modes make the WBC180 a versatile piece of kit for any workshop or garage. Device is compatible with 12V and 24V lead acid batteries, with a capacity of up to 500Ah.

Winter will take its toll on you and your car. The colder, wetter weather and longer hours of darkness mean you are going to have to concentrate harder while driving. Your car, meanwhile, will use more fuel, and harsh salt on the roads will accelerate corrosion. If you live in areas where the temperatures regularly plunge, it might be worth choosing dedicated winter tyres. These are a legal requirement in some European countries, because they make such a difference to safety in the colder months. For our starting test, each device had to assist an ailing battery on a 1.6-litre petrol engine, turning it over five times for five seconds, with two minutes in between attempts. Includes vehicle aux power outlet (cigarette lighter) and mains chargers. Very compact and lightweight: 220x90x30mm / 1.37kg

This new Sealey looks smart and, at just 546g, is not much heavier than the Clarke. Rated for use with 4.0-litre petrol and 2.5-litre diesel engines, it passed our starting tests. Our favourite breakdown warning devices go one stage further, adding flashing lights to make them even more visible. The test-winning Powerlantz also has a bright work light, so it can help you fix problems by the roadside.All perform well and our top four are particularly closely matched. The brand-new MSC just edges out the JSM300 Clarke, with Sealey’s recently launched RS600 chasing the leading pair hard. IMPORTANT NOTICE: THIS PRODUCT IS NOT TO BE CONNECTED VIA A 13AMP PLUG. IT MUST BE CONNECTED TO A SUITABLE INDUSTRIAL SUPPLY ISOLATOR OR HEAVY DUTY PLUG

The WBC180 is a heavy duty starter/charger, perfect for use in garages and bodyshops etc. Large wheels allow easy movement around the work area and the large ammeter at the top of the device provides a clear display of output current while in use. With a whopping 18Ah on tap, the Plus version of MSC’s winner barely flinched at our starting tests, finishing with the battery state still at 100 per cent. Presented in a hard, zipped case, it’s dust/waterproof to the IP65 standard and comes with chargers for mains, USB and car. In addition, it has eight adaptors for charging a laptop; one worked well on our HP. It seems mean to have just one USB, but it has a multi-way cable to make life easier. Massively capable, if heavy, at 919g, this device can do almost everything. Lithium-ion batteries with very low charge cycle requiring only approx 6 monthly recharge if not used. Upgrading the headlamps will make a real difference, because all of the products in our test claimed to offer 200 per cent more light than standard bulbs That will make driving on dark country lanes much easier and safer.You don’t want to find out your washer jets have frozen when you are doing 60mph either, so make sure your screenwash has been upgraded for the cold weather and that you have ‘primed’ the pipes with the new fluid. Includes vehicle aux power outlet (cigarette lighter) and mains chargers. Very compact and lightweight: 220x90x30mm / 1.37

Includes vehicle aux power outlet (cigarette lighter) and mains chargers. Supplied in convenient zipped storage bag With a hefty 13Ah battery, the smaller Ring claims to start 6.0-litre petrol and 3.0-litre diesel engines. It had no trouble with ours, although it was down to three (of four) LEDs at the end.Starting boost output of 1000A at 12V and 500A at 24V and peak output of 2000A at 12V and 1000A at 24V
