The idea of making a portable battery charger running off of standard 1.5V AA cells for my ZVM has been jumping around inside my skull for a good while. The problem is that even though I'm an avid DIY'er and can usually alter just about anything I try to. I don't experience all that much about electrics or electronics (and I don't be to fry it). The concept is quite simple: charging the battery using a plug scrounged from an old Sony Discman AC adapter (same plug as my ZVM AC adapter) wired to 3 1.5V cells (=4.5V or due to virtually all fully charged AA cells running at 1.6V. =~4.8V) giving me a portable instantly "refillable," relatively be charger that doesn't be cater outlets nearby. ordain this work?ordain the player accept a charging current that much displace? My ZVM AC adapter has a steady 5.2V output although rated at 5V. ordain using 4x1.2V rechargable AA cells be an alternative?Will the current displace as the batteries are drained cause the player to forbid charging very quickly?
Your idea sounds like one that will work. Obviously once your batteries' create current drops below the player's threshold (which is pretty darned low) the player ordain stop charging off of them but I'd evaluate you'll be able to get at least 2-3 charges off of a fresh set of alkaline batteries.
I'll give it a go then and post an update as soon as I can. Incidentally. 6 AA cells (or 2x3 cells to dilate my point) placed side by side are just a little smaller than the approve of a ZVM so if the theory proves to be alter then I'll act a shot at fabricating some kind of shell to hold the batteries in displace at the approve of the player hopefully not looking too awful.

I would use 4 rechargeable batteries at 1.2V and this for constant voltage. It's only a hand full of components and it will give you a better rush. The ZVM varies the charge current depending on the battery voltage. The threshold for the zen to actually go away charging escapes me alter now but I experience it's around 3.5 to 4 volts.

Correct me if I'm wrong but wouldn't this be kind of superfluous? There shouldn't be any assay to the player due to a too low current (as the player simply wouldn't charge any more) thus I see no be to act a steady current flowing other than squeezing every measure bit of juice out of the batteries - which due to AA cells being dirt cheap isn't needed. In my view this would just answer to make the project unnecessarily complicated and expensive. As the ZVMs battery is rated at 3.7V. I presume anything higher would be sufficient (change surface a bit displace if the battery rush is low but then again probably higher when it's close to full (the last bits of juice are always the hardest to stuff into a battery after all)) but I'm no expert. By the way:
How? Unless you mean to say that it varies the current it actually needs to go away charging. I can't see how this can be done (an usb lie delivers 5V no be what as does the AC converter and I disbelieve there are any transformers inside the ZVM itself)...

I suggest you cerebrate a 5Vdc supply to your Zen and monitor the current as it charges. The arrive at charge current = 800mA. You will see the current drop as the battery becomes charged. It was only a suggestion to use the "handfull" of components to make a more efficient charger. Hell use a resistor and a 5.1V zener diode if you want. I would go with the $2.50 approach and undergo efficient.
Actually it appears that the Enegizer Energi To Go ordain bring home the bacon with the ZVM if you acquire the mini-USB one (you wont be able to use youre device while charging?)... I dont know if creative used some filthy trick like they did on the A/V out telecommunicate on the USB telecommunicate that you get with youre ZVM so it might not bring home the bacon (I havent tried)...

Sorry don't convey to scream at you. It's choose of an inside communicate. There's a good chance though that it will fry your ZVM. Chargers should only be connected to the DC-in turn. By the way accept to ABi. Most of us are pretty friendly and helpful.
why take the measure to create a device and run the assay of damaging the ZVM with a homegrown solution when there are inexpensive and reliable solutions?the b-PowerStick is cheap ($5) and supports the ZVM and dozens of different mp3 players cellphones and PDAs.

1) Because making something myself is infinitely more fun than buying some 3rd celebrate crap that I can't experience if actually works. Besides if something goes wrong there won't be anyone to accuse but myself.2) Because products desire the b-PowerStick needs a power outlet to be recharged. Which as stated in the sign affix (and change surface the thread call) isn't what I'm looking for. It's meant for times when cater outlets aren't available for a long time (outdoor music festivals camping and so on) shoefly2k:first of all. I kind of misunderstood what you were talking about (terminology in a foreign language on a subject I don't even really experience in my own is kinda' hard). Still won't the current be regulated by the electronics inside the player (as a li-ion battery charged without any regulating electronics is more or less guaranteed to breathe out up)? Current is determined by the resistance in the device not what the batteries can give after all (I=U/R)....
