Re: AA battery powered mp3 player?

"Still can't charge anything when in an electricity free part of the world "

 

There are solar USB chargers, and chargers that operate with a crank. There are USB chargers that run on AA batteries, so you could get one of those with a voltage regulator, and get a solar or crank AA nimh battery charger.

 

 

If you want a AAA battery based player, there are the Slotmusic player and Slotradio To Go player from Sandisk. They have no display though, and sound quality is worse than on the Clip+ or Fuze.

Re: AA battery powered mp3 player?

I just signed up to also voice my support for an AA powered mp3 player, preferably with a memory card slot.

 

Why?  I want to be able to throw the player and a few spare AA batteries in my bag.  This gets even more important when I go on a trip with multiple devices that use AA batteries, like my gps and headlamp.  In this case, the spare batteries work for everything instead of only one device, and the batteries in each of these devices can also serve as spares for the other devices.

 

It's unlikely that I'll buy another Sansa mp3 player, or any standalone mp3 player, unless it runs off an AA battery with the potential for lots of storage.

Of course these external packs that take 4 AA batteries are bulky, and one must also carry a USB cable to use one. It would be much easier to carry a spare AA battery or two and a player that uses a AA battery, rather than a player with a built in battery, an external battery pack, and a USB cable.

 

There are lion battery based usb chargers, however I haven't seen any that use an easily swappable battery. A usb charger that uses an easily swappable 18650 battery would be cool.

Check out the C.Crane Co. at ccrane.com They have a portable MP3 player with an AM/FM radio they call the CC Witness. This is the only one that I know that exists at this time.

The Witness is ridiculous. It is over $168 for a 2 GB player. Besides which, the Fuze seems like a much better player than the Witness(aside from the fact that the Fuze doesn't have AM radio). At over 3 times the price for a 2GB Fuze, imo the Witness is grossly overpriced.

Other features the Witness has over fuze:
1) Stereo input for recording
2) record at "normal" sample frequency (44.1 kHz) and mp3 encoding.
3) extra memory slot is SDHC instead of microSDHC (bigger and cheaper memory available)
4) record on timer
5) clock radio functions
6) record from radio (isn't Fuze just mono from the microphone?) 
7) built in speakers
 
Missing: video

The Fuze does have FM recording in stereo. The Fuze is listed as having 24 hours of battery life vs 16 hours for the Witness. The Witness is twice as thick as the Fuze. The Fuze does lack a line/mic input, and timer recording. The Witness is listed as having just 85 db S/N for mp3.

One can buy a Sony SRF-59 AM/FM radio for just $15. It gets 140 hours on AM, or 100 hours on FM on just one AA alkaline battery(or you could use an nimh rechargeable). A  2 GB Fuze plus a Sony SRF-59 radio is less than half the price of the Witness.

I started this thread more than a year and a half ago, and since then we have still not seen any new AA battery powered players, or even any players with an easily swappable lithium based battery. UGH!

The Slotmusic and Slotradio To Go players use a AAA battery. In my mind they really don't count anyway since they don't have a display, and their sound quality is much lower than that of the Clip+ or Fuze.
