Cradle charger with AC adapter doesn't work

[modem_man]

Hi,

Just purchased a cradle for the universal which has a USB and an AC adapter connection.

The USB works fine for charging the Universal.
The AC Adapter connection on the other hand doesn't charge the PDA at all.

I thought I remember reading something concerning a fix for this but can't seem to find the post for it.

Any body got the solution for it or do I have a faulty cradle?

Thanks.

I would change usb cable

Did you ever find a solution to this?, I have the desktop charger jobby. The grey one that looks like a docking station. It has an ac adapter and a usb out on it .. but like you the charger doesn't seem to work.

p.s its the one with the stylus that stands up straight at the back.

Nope.....
Never found a solution for it.

Dam...

Does your original jasjar/xda exec charger work? mine doesn't.. only my 5v dc 550ma motorola charger works ... oh and the usb direct cable works..

Does you pda charge while sat in the cradle with just the usb attached?

Here's what I have working:

FYI, I have the Qtek 9000.

Original Power Charger - working
Aftermarket Car Adapter charger from Proclip - working
Aftermarket Desktop Charger (AC powered) - NOT working
Aftermarket Desktop USB plug - working
Aftermarket USB cables - working (at least the ones I've tried = 3)

Joe,
I remember reading that you should be careful of what you plug in to power up your HTC-Universal because the voltage needs to be regulated.
Also, don't even go buy those Alkaline battery powered travel charger - they don't work. I even tried with a 9V Altoid Tin Battery Charger (with the required 5V USB regulator) and it didn't work.

I just gave up and carry 2 batteries with me. Planning on getting a bigger battery later on.

Hope that helps.

Thanks for the reply,

Just checked on the web and the moto charger is regulated so it should be fine to use, I was thinking that my original charger may be buggered but because my new desktop charger doesn't work either I don't know what it could be. I'll need to try my cradle with just the usb attached tonight and see if it charges... if it does thats ok .. I can live with that.

My Cradle has a built in usb cable for the pc and a separate dc in socket for the wall adapter so unless it switches between the two i'm thinking that maybe the pins for charging are hardwired to the wall adapter and the data to the pc so it will only charge from the wall and not from the pc..

Maybe I shouldn't have bought such a cheap one :-)

Joe,

I believe I might have the same cradle as you do.

I've open up the cradle to see how the connection is soldered and the points for the ground and powered seemed soldered into the USB port correctly.

I do remember reading something concerning the pins for the USB are wired differently (last 2 pins are shorted - on the Universal-wiki I think) for powered USB charge. Maybe that's why the cradle AC charger doesn't work while the USB cable works.

FYI, I've tried putting both the AC and the USB and you'll find that having the AC in is useless....you're just wasting electricity cos the PDA is still being charged by the cable (just turn off you PC and you'll find that the PDA is not charging).

Does your cradle have the annoying blue LED?

I think all aftermarket cradles are created equal = "CRAP"

If somebody out there have a cradle that have AC that works, please post where you bought it so that others will know which one to get.

Sounds like I have the same cradle as you fella :-), I've tried the usb on its own and it seems to charge ok .. I tested it by putting a movie on and leaving it plugged in, started at 67% its now 77% so its charging through the usb.. dam it .. I could probably send the cradle back since I wanted it mainly for AC charging. Wish there was another one I could get that worked!

Thinking of getting this one instead:

What dya think?

joe....

According to this guy on this thread:
http://forum.xda-developers.com/showthread.php?p=1097137&posted=1#post1097137
his is working just fine.

If you can return it for another one, maybe you'll get one that's working properly.

[vbJoe]

i'm thinking maybe we have pda's from the same manufacture date.. and the hardware revisions are different and thats why our desktop chargers dont work, surely its not coincidence that both of ours dont work?

And if thats the case getting another of the same won't do much good.. theres just no way to be sure about any of this, think I may just send it back and try a different one entirely

Joe,

Good luck!
