RT-AC66U power supply plug size

[tardisious]

I purchased a used RT-AC66U off ebay to use as an access point. It did not come with a power supply and I was good with that because I had an old one laying around. Now I have noticed that the router requires a larger size plug than the other AC66 I used to have. Did Asus use different plug sizes? I am having a hard time determining the larger size and finding a power supply online. Is there a list of plug sizes somewhere so I can figure out what I need?

Some are listed here: https://en.wikipedia.org/wiki/Coaxial_power_connector

• Type A: 5.5 mm OD, 2.1 mm ID (with optional screw lock)
• Type A: 5.5 mm OD, 2.5 mm ID (with optional screw lock)
• Type B: 6.0 mm OD, 2.1 mm ID
• Type B: 6.0 mm OD, 2.5 mm ID
• Type C: 3.8 mm OD, 1.4 mm ID
• Type D: 6.3 mm OD, 3.1 mm ID
• Type E: 3.4 mm OD, 1.3 mm ID

You could buy only a plug for 1$ at aliexpress or in a local store and solder it on your cable.
Maybe one of those or search for other dimensions: https://de.aliexpress.com/item/3294...chweb0_0,searchweb201602_1,searchweb201603_52

Here it says 2.5*0.7mm: https://www.amazon.com/dp/B00GBG1MDQ/?tag=snbforums-20

Thanks, 2.5*0.7mm appears to be the smaller one which is the plug I have and is found on a lot of 19v supplies online that say they are for the 66U. This plug is larger. I will just buy a bunch of ends and see what works. can't find any adapters.

I have two rt-ac66u. One with the smaller size that also fits the rt-n66u and a the larger size which is the same as the rt-ac68 and 86u.
So if you buy one for the rt-ac68u, you will be fine.

then he would need a seldom 4*1,35mm plug seen here: https://www.ebay.com/itm/AC-Adapter...outer-Power-Supply-Cord-Charger-/121956984466
or: https://de.aliexpress.com/item/32813772771.html

I think 4.0x1.7mm or 3.5x1,35mm will fit work and fine too: https://de.aliexpress.com/item/3295...chweb0_0,searchweb201602_1,searchweb201603_52

HEY I FOUND ONE: https://de.aliexpress.com/item/32846087104.html

Or use this adaptor-plug: https://www.ebay.com.au/itm/1pce-DC...emale-Jack-RF-Adapter-Connector-/173851195627

and here is an old thread about it: https://www.snbforums.com/threads/powering-asus-68u-via-dc-not-ac-and-barrel-plug-size.57730/

You know, if you have similar problems, I recommend you buy a universal plug. If a similar problem areas later, this will allow you to use it and not worry that something will go wrong. I bought of several universal smart plugs, so I don't have such problems when I work. But many of the devices I use at work in Britain because sometimes there are such situations. I advise you to buy a universal plug; you will no longer have to think about such problems.

I read in one of the forums that the plug is very specific to the router in terms of the input and output. In my picture all are asus plugs but with different specifications. My newer routers don't even have ASUS written on them. That's how I ended up here, while troubleshooting my plugs got mismatched from the routers and all have the same plug size. I wanted to match the correct plug and router. Any idea if this is correct info?

@kengell You haven't said what routers you have so we have no idea what power adapters they might use.

Go to Asus' website and look at the Tech Specs for your router. It will list the power requirements although not the plug size.

Which adapter goes with what router?
Try looking at the tag on the router!
