Logas Universal Charger Plug 1a Charger Charging Head For Mac Pro

The voltage for is always 5V. The current supplied by USB differs a bit, the standard allows up to 5A but for unregulated devices (eg chargers) only 1.5A max. An unregulated device basically is everything that has no controller (chip) built in to communicate with the other end. There are devices that ignore this specification though, but these can actually break the host controller on the other end. And in your case the charger would be the host controller anyways (if it had a chip, just because the host always is the supplier). If your Sony mp3 player really uses this 1.5A (which allready can produce a fair amount of heat in a battery) it would not be bad if the charger only supplies 1A, the batteries would just take somewhat longer to load.

But for small batteries used in such mp3 players as yours 100mA is considered enough, up to 300mA could be used. Of course there are industry standard AA batteries that be charged with up to 700mA, but this is still below your limit and I guess your player does not use one of those batteries. Always keep in mind that in a circular circuit the current through all pieces is the same only the voltage drops after every part, so charging more batteries in line will be no problem, too.

As long as you can supply enough voltage (which you can because you supply the needed 5V). As other posters have said, USB standard specifies 5 V, so unless the Apple charger malfunctions, it shouldn't fry your player. As for the current, one of the manuals I found specified a battery capacity of 170 mAh and charging time of 70 minutes. Will show that the player should draw about 145 mA while charging, which is about what you'd expect from a portable MP3 player, and way below the 1 A the Apple charger can provide. Conclusion: yes, it's safe to use the Apple charger with your Sony player.
