Is there such a thing as a mains-powered MP3 player? What I'm after is a
boombox which stores MP3 files in flash memory, transferable along a USB
cable. No need for it to play CDs. Would be nice if it had an AUX-IN jack
If there isn't, what are some ways to hack together something like this?
Thanks in advance!
Thanks Rod. But I should have been clearer. I meant a device with some
reasonably OK speakers that runs off the mains and both stores and plays
MP3 files. The files would have to get there somehow, which would be along
a USB cable. I don't need it to play files streamed in from another device
(well, OK, that would be a bonus).
Cool. Thanks! That sounds like the way to do it. I was confusing myself
because I've got a USB dongle MP3 player with audio output along a 3.5mm
cable. This can play through a mains-powered boombox with AUX-IN but runs
off a battery, which is a nuisance. Just using an ordinary USB flash
drive with a boombox would be much easier.

Thanks for this. Still haven't found one that I'm sure has good navigation
though when playing off a USB flash drive.
That's not a bad idea, and ensures you get good navigation. If you used
mains-powered speakers, couldn't you do without the amplifier? Is the
tablet mains-powered? An MP3 jukebox is exactly what I'm after - one that
doesn't require any messing about with batteries.
One of the ipods or ipads with an ipod/ipad dock does and is mains powered.
Yep, and even completely automatic fancy stuff
with podcasts or radio stations etc as well.
Yep, that's what the ipod/ipad docs do.
Plenty of them can be.
An ipod or ipad with a dock qualifys and has the best
navigation around because you can pick any of the
apps you like the navigation style of for free if you
don’t like some aspect of what it comes with.
I wanted to use up stuff I had lying around, so I have a pair of wired
speakers on top of the kitchen wall units and a vintage tablet running a
very old version of Android. Main thing is, the sound quality is
brilliant, so I'm well pleased with it. Not elegant but...

Hum... <google> Ah the chip TA2020 will do 20 W average but with a
THD > 10%. THD skyrockets just above 10 W.
That's probably the route I'm going to take as well but running SB
Player and Squeezer on the tablet working to the Squeeze Box server
over the network.
Most tablets charge/run from USB. The amp needs 12 V, plenty of 12 V
to USB (5 V) modules about. Or you just leave it plugged into it's
suplied charger but then you are starting to suffer wall wart rash...
Which prompted me to revisit an old problem:
[My amplifier has two outputs. One is switched, and used for the
speakers in the living room. The other is taken via a separate
switch box to speakers in the dining room and kitchen. The
kitchen is too quiet.
I used an L-pad to reduce the volume in the dining room, which
closer examination shows is actually working. However, to get the
kitchen loud enough, the living room would be too loud, and I
don't really want to mess with that output, since that is the
best set of speakers.]
I now have a Lepai amp feeding only the kitchen, and at last all
is well. Obviously it is a little more bother to adjust an extra
control, but the results are good, and the amp is a reasonable
match for my little ceiling speakers.

These are mains powered, keep the device charged, play .mp3.
If you don't have something that can stream via the iPod or phone then you
would have to un-dock to add music, but this shouldn't bee a major problem
if your main aim is to avoid using up batteries.
