Many thanks to SWLing Post<\/em> contributor, Anil Raj, who writes:<\/p>\n

I wanted to share a small but useful hack with your readers.<\/p>\n

I use a common garden variety smartphone \u201cPowerbank\u201d 10,000 mAH Li Ion pack to power my Sony 7600GR which is perfectly happy with the 5V which the pack supplies. [See photo above.] I see no reason why this won\u2019t work with other radios which require a 6V supply.<\/p>\n

As you can imagine, the setup typically lasts for many weeks of extended daily listening and recharges in a jiffy. However, one needs to sacrifice a USB cable by soldering a DC plug at the other end. Haven\u2019t bought AA batteries in a long time\u2026<\/p><\/blockquote>\n

Thank you, Anil! What a simple but useful hack. The best part is, battery packs\/banks are\u00a0 very inexpensive these days and, I for one, have a number of USB cables I could sacrifice for the job!<\/p>\n","protected":false},"excerpt":{"rendered":"
