Replacement power adapter for C3700-100NAS Modem

[chris19688]

Hello,

I am trying to find a replacement power adapter for a c3700 router. Does anyone know where I can buy one? I called NetGear support and they don't have them anymore.

Thanks!

Modems tend to use the same plug barrel style. But if you even just search amazon for "c3700 power supply" you get matching ones. 

You don't have to get one of those.

Netgear doesn't sell replacement power adapters. But luckily you can them on amazon. All you need is one that has the same voltage and at least the same amperage. It can have a bit higher amperage because the C3700 will only draw as much as it needs. But the voltage needs to be the same.

Thank you, @plemans... Also, how do i know that the end will fit into the modem (example: I have power adapters from different computers that won't fit this computer - are all modem connector ends the same?). I guess I'm turning into an old lady because I can't figure this stuff out.  🙂

Thank you for your help, I didn't realize they're usually the same size. That helps a lot!
