that lead is what we in the UK call a "kettle lead" (I don't know why - I've never seen a kettle with one,) - it's very standard, and you'll have no problem finding a replacement with a US plug very cheaply.
I'm a little concerned about the seller online4u, since I can only find a US member of that name listed who's been a
member for over 10 years, but has zero feedback and zero items for sale - is that the same seller? You should now be able to post a link, since you've made 14 posts already (I think you can post links after 10 posts.)
Ebay's good for some stuff, but I hope you paid by paypal so you can get your money back if it isn't legit. I'd also echo the advice to buy vaping supplies from known reputable suppliers in future, as recommended and reviewed on this site.
Your carts will be prefilled, and should keep you going until you can get some juice to refill them. Hope you get as much of a 'Wow!' on your first vape as I did - if not, do persevere. There can be problems with some units, and atomizers aren't especially reliable, but when it works it's fantastically better than smoking! And even with the cost of keeping up with spare parts etc., it's definitely cheaper than analogs!
Welcome to the future, Puffdolly
