Why is there no universal travel adapter available for type A+B+C+D+E+F+G+H+I+J+K+L+M+N+O ? (http://www.iec.ch/worldplugs/map.htm#) e.g. a smart device that checks the country it is in and adapts the voltage and the pins with some kind of universal socket.
Or does it exist somewhere? (independent of costs)
(I was looking for an adapter of type D+M and found a gazillion "universal 150+ countries" adapters but none that are really universal) (did not find even one that would support both D+M).
I think this question is not uncommon with customers. But somehow this question is no-where to be found on any of the most famous Q&A sites, which is surprising. So from the answers here-under I see confirmation but still no definitive answer.
- Known: a lot of companies sell world adapters, countless internet sites selling these for "any country", most of them cover the same 150+ countries in the regular regions. Confusing for travellers because often no description is given only a picture. As far as I know no world adapters exist. With as example Type D+M in whatever world adapter out there, and the examples below confirm: it does not exist
- Known: Differences in voltages/frequencies and local safety regulations already apply to existing travel adapters often sold with additional devices and often not. So although no perfect current market. It seems this variable is independent of the question since " it is already so that the market sells unsafe devices"
- The main reason given for not existing is mentioned as a business reason, but without any business research or reference it is hard to quantify. The "why so many" information pages out there (e.g. http://www.iec.ch/worldplugs/why_so_many.htm) covers the " why it historically grew like this in countries " but does not answer the question on why no-one sells a device that is true universal adapter because "any market" has an upper and a lower side so I would expect that somewhere some company would sell a 100% solution on the upper side of the market.
So the answer seems "buy one (or more) for each specific region, no generic adapter exists because of probably business reasons, but no references or research in this market is known. It is not known how much it would costs and it is not known how customers would be interested. It would need to cover A,B,C,D,E,F,G,H,I,J,K,L,M,N,M,O single plugs together with a transformer and possible frequency conversion and taking into account safety regulation. Time will tell if anyone ever will create such a product."
