Looking for specific portable speakers

[Magnus]

I was wondering if anyone had any suggestions for any speakers that would fit my requirements as I've been having a hard time tracking some down and need some for when I'm away from power to listen to subs

Ok requirements are

* Portable and not to large
* Can run on AA or AAA batteries
* Can charge my phone through USB in the speakers or have a place for an SD card to slot into to play music off
* Frequency response rate of 20khz of course for subs
* Prefer a playback time of above 8 hours but can work around that
* Of course the cheaper the better as my budgets a little slim

Thanks in advance for any suggestions

This is probably just what you're look for, found on Google.

Thanks Ryan

Unfortunately I can't see any USB connection on them for charging my phone on which I use to play subs through otherwise its perfect

A speaker that also charges your phone? I haven't seen a thing but you may find 2 separate battery powered items, 1 charger and 1 speaker.

Actually. Look at Target. I once picked up a cheap MP3 player that runs on AAA batteries. I use that from time to time on trips.
