Our business supplies to the hair and beauty trade, and over the years people have tried gas powered appliances,none have been succesful, there are some curling tongs available for retail, ie Argos , Currys etc, but the professionals always use electric,there are some straighteners available in the trade that are rechargeable, but they need recharging from the mains after every use, so sorry girls it is either mains or the wash and wear look in the caravan
