Low Noise AC Adapter

[pjxii]

Does anyone know of one with an OD of 5.5 mm, ID of 2.1 mm, positive tip and output of at least 300 mA? The WiNRADiO WR-SF-41-US seems like it's low noise but is rated for 200 mA.

These adapters can be brutal for RFI, here in my new location it's very noise free except for when I forget that my cell phone's cheap and poorly made charger is plugged in, or in winter when my heated blanket is on.

First, I can charge my phone from the USB buss connected to the computer and it's low noise. Second, you're in Florida and you need a heated blanket?

Actually, I don't have a computer, just a cheap smartphone, and I moved to Alabama last year and compared to SW Florida winters here are COLD!

You didn't say what voltage but from memory the WinRadio units take 12v I believe. If so then here:

Amazon carries these adapters at times so you may want to use the PN to check on Amazon. Delivery would be quicker.

Yes, sorry 12V is what I need. Thanks for that link.
