About the NOCO GBX75
From our tech experts at CEN
A lithium jump starter, rated at 2500A, small enough to live in the boot and start a car without another vehicle or a set of leads.
Who it suits
Anyone who has been stranded by a flat battery, and drivers of cars that sit for long periods — classics, second vehicles, campers and anything seasonal. At this rating it will turn larger petrol and diesel engines, not just small cars.
Our tech experts advise
Keep it charged: a jump starter that has sat in a cold boot for a year is no use when you need it. Check the rating suits your engine size, particularly for diesels, which need considerably more current than petrol engines of the same capacity. get in touch if you are unsure which model fits your vehicle.
