For a few months that I have, and I found the following strangeness to recharge, it must be recognized by a PC turned on! Not possible to load it with a "USB Power" where a single hub to power. Frankly I do not get the value of this mode ... Another thing: When you unplug the USB once full batteries, IT IS THEN RUNNING !! And if you do not turn off, you drain the batteries ... I almost returned the believer to a failure thereof ... The FM recording microphone which is at 24kHz 16bit instead of 22.050 KHz 8 bits for the Zen Nano + I had before. And the difference means. The microphone is also more sensitive, and higher quality. downside: when I could save 15H in 1GB Zen is 8 hours max in 2GB Sansa. Just empty it daily as needed (which recharges the batteries at the same time). Tuner a bit less sensitive than the Zen which is exceptional on this point (put the tuner in mono to improve the thing), IMPECC sound quality lez replace original earphones for the purists ... Duration of variable batt but at least 6H with record function activated 3/4 time. If there had been a model a little bigger and expensive with a high-capacity batt I would have been client. It is true that it is almost as light as the headphones we will branch ... The batt can not be replaced ... I hope she's tough ...
