CCrane “Witness Plus” AC Adapter Review Now Posted :
The CCrane 5 volt USB-mini REGULATED AC power adapter (for the Witness +) is perfect for use with OTHER USB radios and has a 900ma MAX current rating.
Works with either Tecsun or Degen with the mini-USB plug (and the GRE PSR-800 too). Pin 4 is + and is truly 100% analog and extremely clean . It does NOT use switching electronics AND OR a switching regulator.
My mini-review is now posted and can be found on the “dead bottom” of the Sangean ATS-909X / Tecsun PL-660 / Tecsun PL-880 review page.
Thanks, Dave! Finding a proper regulated power supply is not easy these days. I’m very happy to hear this C.Crane model gets your approval!
