[mikeco]

i got this usb wall charger yesturday off ebay:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ih=006&sspagename=STRK%3AMEWN%3AIT&viewitem=&item=160077572061&rd=1&rd=1

and i cant get it to work with my zune i dont feel like paying £15 or whatever it is for the zunes proper wall charger and also having to have an american to english adaptor on it so i got that insted for just under £5.

its very small and seems realy nice but i just cant get it to work.

when i plug in my zune to it with the cable the light on the plug its self goes off... which from the ebay info for the item says its a power indecator.
my zune doesnt even notice the charger :huh: screen doesnt light up or anything when it connects so its not noticing it at all.

says this on the plug:

* Input: AC100V-240V. 50Hz 130mA
* Output: DC5.0V ± 5%. 500mA ± 50mA


any ideas on how i can get it to work? :ermm:

How many mA does the Zune player need?

im not sure cant find any offical info about it but found this at amazon:

"Monster Smart Digital Charger technology delivers the precise charge your Zune requires 500mA maximum power output for fast charging while enjoying movies or music Supports 110v-240v AC power"

The zune should be able to charge from a USB port, so there's enough current.

It's quite probable that the Zune requires a signal from the host to charge from the USB port, that's certainly the case with my phone (a windows smartphone).

If I connect my phone to a USB port without having ActiveSync installed then it won't charge. Similarly if I connect it to a USB charger which isn't intended for my phone then it doesn't charge from that either.

In my case, it requires a data signal, or an input on the Mini-USB-A Master pin, either of which tells it to charge. Obviously the Zune has a different data connector, but I suspect that something similar is going on.

That makes a lot of sense!
