Hi.
My MP3 player is a Creative Zen Xtra, which has a 3.6v Lithium Ion battery, and takes a 5v power supply.
However, If I'm away from home, and run out of power (it eats batteries), I want to be able to charge it up using batteries I can buy from shops (I.e. AA, PP3 etc). However, if I use a PP3, I need to drop the voltage down to 5v. Simplest way seems to be a regulator. Looking at the mains power supply, it says it can supply 1.5A. I'm guessing a 1.5A reg would get pretty hot. And so would waste a lot of the battery power. So I may not get very much battery life out of one PP3.
I don't know what the capacity of the MP3 player's battery is, it doesn't say.
Does anyone have any suggestions?
I have seen people who put four 1.2v NiMH batteries together. But at around £6-10 for a set of decent capacity NiMH batteries, and £10-20 for a charger that can charge them, thats rather a lot.
Cheers,
Tim
