Hi Thomas I enjoy reading your blog and often when I put a question in Google yours is the first on the list so I wonder if you’d mind if I ask you a question about the Sony SW35.<\/p>\n

I’m interested to try powering it from a power bank but I have no idea what DC plug to buy for it as I bought it second-hand without an adaptor.<\/p>\n

I thought about taking a couple of wires out of the battery compartment but it wouldn’t look as nice so any help you could give me would be much appreciated.<\/p><\/blockquote>\n

Great question, Adam! <\/span><\/p>\n

You can certainly find a DC plug that will work with the ICF-SW35. I believe this same plug was used with a number of Sony Walkman type players back in the day. You might be able to find one at the local charity\/thrift shop in their power cord jumble.<\/p>\n

\"DC<\/a>I do know that the coaxial type plug needs to have positive tip polarity (click here to read about this in the owner’s manual<\/a>) and the radio requires 4.5 VDC . The OEM power adapter (Model AC-E45HG<\/a>) provided 700 mAh, but I don’t know what the ‘SW35 actually requires (other than something equal to or less than 700 mAh).<\/p>\n

One option would be to find a 12VDC to 4.5 VDC converter like the Sony\u00a0DCC-E345<\/a> and plug it into a 12VDC source (there are a number of high capacity 12V battery packs on the market).<\/p>\n

Of course, you could also build your own external source by purchasing an appropriately sized external battery holder. I would use a D cell holder (I assume one to hold 3 cells at 1.5VDC x 3 = 4.5 VDC) which would provide much better capacity than a AA cell holder. (Something like this.<\/a>)<\/p>\n

I haven’t been able to determine the +\/- voltage tolerance of the ICF-SW35, so I would keep the supply voltage figure at or below 4.5 volts.<\/p>\n

One crucial number I’m missing is the coaxial plug size. I can’t seem to find a spec for OEM Sony\u00a0AC-E45HG<\/a>. I hope a reader might be able to help us here.<\/p>\n

Post<\/em> readers:<\/strong> Can anyone confirm the DC plug size for the Sony ICF-SW35?\u00a0 If you have any other advice or tips for Adam, please comment!<\/p>\n","protected":false},"excerpt":{"rendered":"
