Is it really portable? What is the size and weight?

Yes, it's portable! With the legs folded, the BioLite Portable Grill packs down to 3.5 inches tall by 12 inches wide and weighs only 1.9 pounds. Combined with the CampStove, that puts your whole system around 4 pounds - as a frame of reference, most tabletop grills weigh anywhere from 8-20 pounds on their own, not including the charcoal or propane you'd need to carry.
