Next camping trip, swap out the fuel typically required to operate portable grills for a pair of AA batteries. Running on virtually any flammable solid (wood, cardboard, pinecones, twigs, etc), VitalGrill’s secret is its battery-powered blower that fuels the flames and boosts heat output dramatically, pumping out 20 000 BTUs (enough to boil 1L of water in roughly 3 minutes). The lightweight (1.6 lbs) grill folds up to neatly fit in a backpack, picnic basket or briefcase – because who says lunch at the office can’t be freshly grilled?
