Meizus are rated at 20 continuous music playback and 6 hours of video playback per charge. If you need more, there is a USB battery pack that can be used to either charge or play the Meizu. It has 28 hours MP3 playback. It takes two AA batteries and is $12 at House of DAP.
However, built in speakers are nice. I got my mom a Meizu clone with a built in speaker. However, hers doesn't hold up against mine any other way.
