External Battery Pack

USB OTG meas to that a device can act as an USB host (master) and can be connected to another USB device to exchange data with it beeing controlled by the host.

My intension would be to connect a portable USB hard disk to the Meizu and play music or video from the hard disk or watch images beeing stored on the hard disk.

My Samsung YP-T8Z only can pull data from an external USB device but can not play or display it directly.

Shine On, Frank

But this "new" version of the battery pack, have support for OTG, It's just the FW in the miniplayer that dosn't got support for OTG yet? So I don't have to buy a "new" battery pack to get support for OTG later..

And as "fores" wrothe.. will I be able to playback things directly from the device I have connected or just "pull" the data? If it's just for pulling data i'm not sure i would have bought it. =/

Clearly, OTG support can be enabled for the meizu's built in USB port. If they write a firmware to ONLY recognise the USB port (for OTG) on the external battery case.... that'd be forced marketing imo.

Im sure they will release OTG. but Maybe in a special firmware maybe taking away something so they can fit OTG. you never know

So has anybody pulled one of those apart yet?

If I had one it would have been taken to pieces and (hopefully) re-assembled many times =D

When/If I do get one I'll put any circuits and pinouts online for anyone who wants to build their own... you might have to wait a while though.

That would be great. A little DIY project.

What you have to bare in mind is that many devices require power from the USB port, especially some external laptop-harddrive enclosures and USB pen drives - which are powered ONLY by the USB port. With this in mind the USB port spec requires 500mA of 5V power. Under normal operation the port on the M6 doesnt have to provide ANY power, as the device acts as a slave, powered by the computer, recharged by the computer, etc.etc.

Because of these additional requirements for decent USB OTG (On-The-Go, Repeatedly & incorrectly referred to as USB host in this forum) support, it is quite possible that there is a technical NECESSITY for the additional power provided by the battery pack.

Hope this helps explain

sorry to bring up a old post , but does the usb port on the battery pack supply power , can i charge other devices , ( i know its for otg support but if it dosnt supply power there would be no need for the external batter pack and you could just use a pinout map and wire up your own cable ) , so if someone plugs a device that charges via usb into the port and switched the button on wil it charge??? , thanks

B-W-D is correct as this was stated when the Battery Pack USB-OTG was first released. I think Meizu is having trouble getting the transfer speeds fast enough, last I heard it was slower than USB 1 speed and Meizu was not happy in releasing USB-OTG at such slow speeds as it would not make the customers happy.

As it provides power I am sure it can recharge or power what ever you plug into it. The cost of the battery pack is not much and would be worth getting once USB-OTG becomes available in firmware.

It appears that it will charge other devices, and even simultaneously. I had two M6's plugged into it, one through the standard charge plug, and the other through the USB port and both indicated they were charging.

Tested this on my Ipod Nano, Telcast T-29 and Simens S88 handphone.
With their respective USB cables.

All the above shows charging: as well as my M6.

I think it can charge any device with USB charging connection.

Got this Emergency Charger in an MO,
Best battery charger I have thus far.
cost wise and device wise.

PS: didn't fully charge, so can't tell if battery current can last how long.

Not much to see. The chip is marked as AC-86 30S, whatever that is. Beside that a couple of SM caps, a resistor, LED and a three pin regulator (?). Nothing obvious under the USB socket.

Ok guys this is big! You can plug whatever you want directly to the M6 miniplayer once the firmware is out! From the pictures supplied by kh1234567890 (thanks by the way). You can see that the 4 wires are connected directly to the USB leading to the miniplayer. The resistor and the regulater are for regulating the current and voltage.

How much does this ting cost?

Well ive already created myself a simple USB Input - M6 Type usb for use with OTG

House of DAP has them listed for $12 plus $6.30 S & H. There also might be some available on eBay. Not sure where else. I wish JTC had them. I'd buy from him any day.

Has anyone extensively used the battery pack? I just took mine on a trip overseas, and could not figure out how to use it.

I tried all the different combinations:

Meizu on - 4.7 v.
Meizu on - 4.3 v.
Meizu off - 4.7 v.
Meizu off - 4.7 v.

When the Meizu was in the "off" position, sometimes, I would get notification that the battery was "fully charged," only to turn it on and see that it had no charge at all.

Other times the screen would just turn white. Sometimes, when I was using the Meizu ("on"), the small battery icon would be cyclically increasing as if to tell me that it was charging. It would seem to last a bit longer than normal, but then say "low battery" and shut off.

ONE time I checked the M6 and found that it was fully charged from being completely empty...however, I could not recreate that effect.

Can someone help?
