The priciest choice here, but the XP-10 oozed quality. Its chunky carry case housed a whopping 16 connectors – over twice as many as rivals. Safety lights on the clamp component also alert you if you hook up to the wrong terminals. The jump start was effective, with A-grade lithium batteries giving more jumps than rivals between recharging – itself a quick process. The various ports mean it can be used on more than just the car, too.
