Designed for foreign travellers visiting the Americas, this non-earthed Transworld travel adaptor + twin USB charger converts the most common 2 and 3 pin / blade plugs to the American electrical system. The convenient ‘twisting’ blades allow the travel adaptor to be used in Australia too. The double USB ports have a combined auto-regulating power output of 1.3A, ideal for charging small electrical devices such as a smartphone or an MP3 player.
