Euro > US Power Adapter

Thu Jul 05, 2012 7:53 pm

Okay, so in all the excitement I overlooked the fact that I had selected a European power supply for my Pi. Yeah yeah, it happens. I imagine the cost to send this one back for replacement may be more expensive than purchasing a brand new one US power supply. I've been looking around the forum (and select other sites via Google) but I couldn't find any solid answers or 100% safe solutions. Could I use the ~$11 Euro > US Power Adapter (not converter) from Radio Shack or would I need to fork out more dough for a converter?

If anybody has any suggestions I'm all for them. I don't mind waiting. I've already waited 3 months to order and 1 month for shipping so another few months isn't going to hurt I guess. I just don't want to end up spending $100 for something I was hoping would be $35.

In other news. I may have a European Power Plug for sale ;)

I don't know what features the PSU has you ordered, but I think for the 11 bucks you can get one of those 5V 2A USB Chargers an a USB do µUSB adapter cord.
Maybe your PSU will work with 110V and an adapter is ok. Can you provide a link to the PSU you ordered please?

Ok, the datasheet says it will work from 90Vac, so a simple socked adapter will be fine. 11$ seems a little high tho, we sold single adapters for about 2€ a piece some years ago.

most such adapters are designed work with a voltage between 90 and 250V AC (50 or 60Hz), just for economics of scale.
In any case a (low power) switching power supply designed for 240 is for technical reasons very likely to also able to work on 110V, even if it isn't explicitly designed for it.

Must be one like this:

says "1A 5V" and is CE marked, delivers 100mA at 4.5V and is dangerous as hell, and CE means "Chinese Export".
Yes, you can buy power adapters that are too cheap, no surprise really.

nope, I meant an purely mechanical socket adapter to fit euro plugs into US 110V sockets.

That's Radio Shack for ya. I'll see of there are any other obscure electronic peripheral dealers in the area but after too long time is money. Thank you very much for the info.
