Electricity – perhaps the biggest and most monumental invention in human history; one that's given rise to the advent of over a century of vast technological advancements, including perhaps its greatest feat: the electric golf trolley.

OK, maybe we're exaggerating, but there's no doubting that in the golfing world, a battery-powered, motorised caddy bag is both a hugely useful tool and a very cool invention. The Powakaddy FW7 is the cream of the crop: it's lightweight; it has an electronic braking system; a battery fuel indicator; an anti-tamper lock; and, most impressive of all, it'll drive itself across the fairway, leaving you more time to focus on your game.
