Hi Monica. I've checked the US site and you are correct - it doesn't appear to come with the "travel adaptor kit" which is part of the product name here in Australia, while not on the US site. They've removed the product picture that features the extra adaptors, so it looks like this is deliberate. Strange as the connection to these adaptors is unique to Berlin so you can't add an adaptor easily. Perhaps this will be offered as an accessory but I don't see it on the US site anywhere...yet...Thanks for your comment!

@@gadgetguytech I’m not familiar with the currency conversion but the version that is sold in the US is approximately $60 USD not including taxes so it might also be cheaper than your version. I’ll purchase it anyway. Should I travel abroad outside the US then I’ll have to get something else but for daily extra battery or US travel, it’ll work. I wanted to ask your opinion about using this as a regular plug. Do you think it over charges?
