External Battery working?

Hi
I am thinking of buying a Music Card, but the battery life seems a bit low for a traveller. Is is possible to use a device such as this one (an external battery that apparently zorks for the m6) to make the player last a bit longer.
Or asked differently : can you use the player while recharging it? (I am not sure it is exactly the same, but it should be)

Thanks

ps : no i don't wanna buy the iaudio 7 brick because it is too ugly

Yes, it works for M3 too.

how long are your travels?
anyway... an external batterypack will work

i also came across a wallet sized flip open solar chager for usb devises...
pretty cool to get a bit of extra juice if your in the sunny middle of nowhere...

That's how his post counts are past the thousand mark puffel

Thanks for the answer.
I'll be moving around south Asia for a while, without the insurrance of getting 110V every day. And considering the battery life seems to be a bit low (At least until the next Firmware I hope...)

ps : Thanks for the tip about the Solar charger, I will give it a look.
