Yep, exactly. The brick/wart does the converting. And it's easy to get a new brick if you match the output voltage/current exactly.

I'm loving the Asus routers. Excellent speed. the 66U and 66AC are both the best in class as far as I'm concerned.

Apple routers have built-in power supplies. So there's that.

As others have said yes, the router itself is the same whether it's purchased in the US or Europe, only the AC adapter is different to match the target market's voltage/current and plug type. That's why I recommended earlier that you go on a scavenger hunt to find an existing wall wart adapter with dual voltage input and matching output specs and exchange adapters.

For example: I have a cheapie 8-port ethernet switch which came with a 110 only, 7.5VDC adapter. I want to take this switch overseas and instead of buying a new adapter there I found that I had a wired print server which had a 110/220 7.5VDC adapter which is staying here. Just swapped the two adapters and everything is happy.

Not all of them.

Would that be the same with phones (cordless home phones)? I need to bring one with me to plug into an Obi device, but the phone jacks in USA and Israel are different, and I need one compatible with USA sizes. If I bought a phone in America, could I just find an AC adapter in Israel that matches that phone?

There are universal adapters that come with a range of tips and selectable voltage outputs. I would not rely on finding an old one that happens to fit. Of the dozens of wall warts I have laying around the house, I have never found two that were interchangeable. Even if it looks like the tip is the right size, you may find a slightly different diameter that does not make reliable contact.

It's certainly possible but many new cordless phones have the AC adapter wired directly into the base without a plug and jack. For the Obi I would purchase the cordless phone in Israel and either crimp on a RJ-11 plug or get an adapter like this:

(the description is backwards, but the picture shows the right adapter)

IIRC the new Israeli plug is the same as the UK version but YMMV.

Yes, almost all cordless phones use DC adapters. This applies to anything that has a DC adapter and a small thin cable that plugs into the device itself. Another way of checking is whether there is exposed metal that you can touch on the end that you're plugging into the device You'll never see that if you're plugging AC power straight from the mains into a device:



Every adapter will show Input (AC volts, usually around 100-120 if it's US only, around 200-240V if it's rest-of-world only, around 100-240 if it's universal) and Output, in DC volts. The polarity is also normally shown, i.e. whether the positive or negative terminal is on the inside or outside of the connector.

Except if it was the same model phone, (or router,) then it likely would have the same plug

Be forewarned! when entering Israel IF they search you/your luggage and find the cordless phone and or the Obi device and you do not have approval for them they are going to be confiscated and/or destroyed.
If the cordless phone is 900mhz it is not allowed at all.

They did not stop me (this time) and I brought the Obi device in, no problem. Regarding a phone, that guide didn't apply to me as I don't enter Israel on a visa. And it seems, based on another linked guide in there, that I can bring in the phone for free.
