content: I encountered some very similar, but different mains plugs from this document:http://www.deltapsu.com/products/download/Datasheet/MDS-030AAC05In that document, A-B (CN-US) plugs look almost identical, C-G-K (EU-KR-BR) plugs look similar, and E-J (AU-AR) plugs also look similar (despite reversed polarity, but for a 2-pin non-polarized power adapter, that won't matter).If my understanding is correct, the only difference between Chinese plugs and non-polarized US plugs it that US plugs have a hole on each blade. The only differences between Korean, EU and Brazilian plug is the BR/KR ones are straight and the EU ones are slanted. The BR ones have thicker contact than the KR ones. The Argentina ones are visually identical to AU ones, with reversed polarity.But I believe they all can plug into each other's sockets of the same group, and I've been mixing CN/US plugs for years without problems.So my question is, will it be legal to distribute similar but not exact mains plugs with my product?

content: I'd guess the answers are potentially different based on which governments you're dealing with, what the country of manufacture is, and where the point of sale is. And whether you are worried about your liability, the customers liability, or both?

content: The simplest thing for you to do would probably just put an IEC socket on your piece of equipment, and have it rated to accept 100- 240 volts 50-60hz.Then you can decide either Supply a power cord for whatever country you're sending it to or leave that up to the user to grab one.Sent from my Moto x4 using Tapatalk

content: I mean most UK appliances used to come without wall plugs, you had to wire your own.It's still not hard. You can likely find a compliant cable with good ratings quite fine. For a charger like this, it's a bit different, but if you wanted to get fancy, you could just have a straight national mains to IEC adaptor. That way someone can even use a power cable if they wanted to.
