The performance of the Oliwatt 2 electric comb is even further boosted with the all-new ETA BETA Lisam patented portable generator, powered by a 4-stroke Honda engine. When used by a single operator, ETA BETA may be carried as easily as a backpack, using the shoulder straps supplied. When used to power two electric combs, ETA BETA may be picked up and carried like a suitcase, then set down on the ground on its special feet, allowing two operators to work at up to 30 metres from each other.
