“Bought this as a winter accessory, which is handy as well throughout the year. Have plugged it in and charged it up to the recommended level but have yet to use it for a jump start. Tried the tyre pump and that is working okay. Everything looks to be satisfactory. It is of a good build and heavy construction which gives confidence for good longevity of working life. Not an item to use on a daily basis but one to be good and reliable item when required.”
