Cradle charger with AC adapter doesn't work

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.

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.

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!

Problem of recharging TP2

Hi.
i got a unbranded Touch Pro2 in france. the battery stand 2 days before the first recharge. but seems i got a problem of recharging.
i decide to recharge it when the phone is ON, but seems it consumes more than recharge speed. there are less and less electric in the battery, even the screen is Off, and no applications running, and all connections are disabled (WIFI, Bluetooth, Data Connection) except Phone
so i have to take the phone completely OFF, with a cable USB connected to the computer, now it is more than 6 hours, but the recharing light is always "Orange".
this is my 3rd HTC phone, and i never met this problem before. as the first recharge of TP2, is it normal to me?
thanks in advance of your help

Try the supplied wall charger - will do the job a lot quicker!

Thanks, nearly 6.5 hours with usb cable. the light turns green, so i can start it now.
but i still not understand why it consumes more quickly than recharge. i will see if it happens only in first charge.

I saw somthing somehwhere about turning on quick charge or full charge via activesync usb, dont know what its about but its worth investegating if this is a problem for you.
I have another charging or connection problem, with all my other htc phones (5) i could use any regular usb cabel, with the pro 2 they all seem to have poor connection, have to hold the cabel in a sertan angel for it to work. The supplied cabel and the org cabel for my pro 1 works fine though. Anybody else having this issue?

same here - but applies to all my htc phone. they can not connect stability with the mini-usb of my SLR camera. in fact, there are a little different with HTC ext-usb and mini USB -- the port is a Right-angle trapezoidal, while the standard mini-usb is Symmetric trapezoidal. so that's why we should use the ext-usb cable.

same here with the usb cable ...well is not the usb cables problem but the usb plug in the phone .
concerning charging from a pc laptop.....
if i leave my phone overnight charging from the laptop and the laptop goes into standby ,even if the battery is 100% it gets totally discharged with in hours!!!! this while plugged into the laptop!!!
what a hell is this , i mean, m i charging the laptop from the pda or what!?
this is a serious bug that htc needs addressing.
please note that there is laptops that do not power down usb ports while in standby, i got one that does just that.
now my eee-pc1000h doe power down the usbs ports when going into standby.

Well i know that but that is becous they also have the headset on the same port. As far as i know you should be able to use a normal usb cabel with the device.

USB ports on a computer can only supply 500Mah of current. it seems really odd that the phone would be discharging at such a rate to deplete itself even with that current available. that would seem to indicate the 1500Mah battery in the Tp2 would only last 2, maybe 3 hours before dying if left unplugged.
when connected through a Wall outlet the phone should be being charged at 1000Mah. although the maximum safe charge rate of the battery is 1.5Amps (1500Mah.)

I have noticed that my TP2 can complain with a popup warning that there is insufficient power to charge when connected to my Dell laptop. I think it just stops charging at this point. After that it is downhill all the way!

I agree that there is something strange going on with the TP2 recharging from a USB port. I got my TP2 as a replacement for my HTC Universal. I am using the TP2 on the same port with the same cable. The Universal was very straightforward - plug it in and it charged regardless of whether it or the PC was on or off. The TP2 is very different - leave this connected to a powered off PC overnight and I routinely find that the TP2 has reached critical battery low the next morning. This means that not only does it seem not to have been charging, but it must have been "on" overnight (where the power management settings should have turned it off) in order to deplete the battery to this extent, regardless of whether it was charging or not. The battery charging light (amber to the left of the ear speaker) is on throughout.
The power management information is also odd. This AM it reports last full charge at 23:12 last night and since last full charge a standby time of 6h39m, talk time of 0 and device usage of 2h55m. However, it wasnt used at all after about 20:00 last night and power management should have turned it off after 30 mins.
It charges normally from the USB port when the PC is on.
Any ideas?

This problem happens with standard USB cables and the official HTC cable. You must have an active ActiveSync connection or the phone won't charge.
Last night I plugged my phone in while my computer was still booting. The charging light came on, but this morning I was left with 10% battery.
If you plug it into a computer without ActiveSync installed the phone won't charge.
If you plug it in and the ActiveSync icon turns green the phone is happy and will charge.
If you turn off the phone and plug it in to just about any USB power source, the phone doesen't know better, and it will charge.

I got the power error in my car last weekend. Running with the splitter, with 3.5mm into car sterio and car charger plugged in. Was running slide2play and the pop up showed up. Come to find out, later on the charging light wasnt on the phone anymore. Tried the wifes tilt 2 and it wouldnt charger hers either. The car charger died.
BUT, at the time the error came up, the charging light was up and running.

Problem with TP2 and Mini USB sync/charge cable
I have an unbranded GSM TP2. It charges normally using the HTC wall charger and the HTC supplied ExtUSB cable.
I have read that Mini USB cables should be compatible with the HTC ExtUSB port for normal operations like charge and sync so I bought a generic Mini USB sync/charge cable on e-Bay. The supplier stated it was compatible with TP2, but when I plug it in to USB port, the device charging light comes on for 1 sec then goes off and the PC shows a message saying "a USB device has malfunctioned".
The supplier sent me a replacement cable but it has exactly the same problem so I don't think the cable is faulty. I think maybe the problem is with my device.
Does anyone out there have more detailed knowledge of the compatibility of Mini USB and ExtUSB?

No, I am just using ActiveSync to sync my data and charging via USB whilst connected.
As I said, it works perfectly with the standard HTC ExtUSB cable but fails to connect properly when I try to use the Mini USB cable.

I think the odds are you just got a bum USB cable...the failure rate among the generic ones on e-bay is considerably higher as a rule. Do you or any of your friends have any other mini-USB equipped devices you can test it with?

That was my first thought but I have now tried three different cables, from two different e-bay sources, with the same effect. However, I haven't yet tried any of them with any other device - I'll try that at the weekend and see what happens.

CDMA Touch Pro 2 - Charge from PC/Laptop?

Sorry if this is a duplicate thread, I searched quite a bit for a solution but only found stuff for the TP, not the TP2.
Ok, so I know with the original TP you could charge it from a computer, but it was not as fast as a wall charger unless you had the fix that allowed it to charger faster on the computer.
Well on my TP2, it really won't charge the phone, and if I am using something like wifi router that uses a lot of power, it will actually lose power while charging off my computer...
Is there a fix to bypass this so I can have my phone plugged into my computer and charge it???

make sure in your battery settings the box that says "when device is turned on, do not charge the battery when connected to the PC" is unchecked. meaning an empty box. if its checked off, uncheck it. also, this might help, when plugged up to ur computer, cut ur backlight all the way down or low. the phone will use less battery that way and will charge faster when hooked up. either way though, charging thru a pc is trickle charging, meaning its gonna b slower than wall charger anyways. i havent came across the fix u mentioned for the TP.

trickle charging is when battery is fully charged and is still pluged on charger, then charging change to trickle power charge, around 20mA+actual request of the phone. this way if you have phone/any electronic in general on charger for a month, it's still kept fully charged.
---
htc have two modes of charging slow 500mA and fast 1A (1000mA)
to say to the phone that charger is fast, you need to have one pin on mini-USB connected to ground. this pin is unused by mini-usb specifications but htc is using it for this trigger.
---
cut open mini usb connector on usb to mini usb cable and wire the unused PIN to power ground (get pinouts pics or use multimeter!!!!! don't guess try it)
then you still facing another problem, USB is strictly specified to not exceed 500mA (with 10% toleration) no trick to get more then this from one usb. some computers are not so precise with rules though and could give slightly over 550mA
to get 1A you need to use two usb ports in parallel. like some china made usb harddrives enclosures
get an additional USB connector and add it to your cable.
NOTE: DON'T CONNECT DATA LINES ON THIS SECOND CONNECTOR!!!!!
data = inner 2 pins
power = outer 2 pins
* you can get an USB extension cable, wire 2 power lines out of it, connect to your usb - miniusb cable... this way you still can use the other usb for other device
NOTE: this is not a standard though accepted solution. I haven't saw or heard of any burned computers cos of this but wouldn't be surprised to see one.
anyway if I had that need, I would go for it
when making this cable, be very sure 5v wire is not touching data lines!!! Test it properly before plugging to PC! I have brand new laptop now, the old one is lying with DEAD usb host below table just because I believed there have to be protection against this. There IS NOT.
NOTE: NEVER LAUGH ON MY PAINTINGS!!

Or you can buy one for $4
http://eshop.macsales.com/item/Othe...medium=shoppingengine&utm_campaign=googlebase

actually NOT.
without grounding the special pin on mini USB side of the cable, mobile would charge by 500mA no matter if you put 100A charger in. or paralleling 20 USBs

Wow...I'm pretty tech savy but that was a bit confusing...so I get the gist of that, but how is it that all it takes is plugging the usb chord into the htc ac power supply will fix that? why isn't it required for all that jazz of rewiring crap on the ac adapter as well, since it comes from the same usb chord...?

eh, have mercy with that english slang we are mostly not englishers here
What you meant was, why htc AC (wall) charger charges on hi power without those tricks?
Because the connection is already made there.
That's not a hidden trick anyway. Not even trick. It's a standart feature.
HTC is, not like other manufacturers, sticking to specs and mobile would not demand more then 500mA from standart usb connection.
usb is defined to be max 500mA
if you want a connector which is based on standart (htc's usb-hub can use usb cables), and you want a fast charging without violating standarts than this was the best resolution, to use pin which is generaly unused to trigger-detect 1A charger.
But as htc didn't made computer fast-charge cables. A serious company will not release such a cable. Connecting power from two usb hosts together - I feel pain by doing it, but it proved computer stabilizators don't mind it and though I don't think it's giving really double, it's giving more then 500mA.
But here you have to "imitate" original htc AC charger by shortwiring that trigger pin the way as it is there.
hope this was your question about.
Just final note in red when making this cable, be very sure 5v wire is not touching data lines!!! Test it properly before plugging to PC! I have brand new laptop now, the old one is lying with DEAD usb host below table just because I believed there have to be protection against this. There IS NOT.

[Q] Slow USB Charging in AC outlet

Whenever I plug my Desire in an AC outlet, it charges ridiculously slow. I check the battery status and it says "Charging (USB)" (not AC) and USB Debugging pops up. My wall adapter says it has an output of 1000ma. Is the chord bottle-necking the charging speed or is it the adapter? I am using the chord that came with my phone but I bought a new adapter to fit my countries outlets.

Same problem. I would like a resolution to this also.

There is allready a thread concerning this issue and it has the solution your looking for.

I have looked on the forums and it should seem like I should get regular AC charging on my Desire. I have a 1000mah charger and I am using the USB cable that came with my phone. I am wondering why I do not. I looked at my USB (fat side) pins and they are shortened. I have included an image of my charger.

if the adaptor says it supports iPhone etc then that is why the USB debugging symbol is coming up.
because that symbol is up it will only charge at 500mA max (the phone thinks it is in a PC, it doesn't wnat toburn out the USB port).
if it is a cheap adaptor, the voltage regulator may be limited to 100mA. thats what happened with me.
either way, in my eyes you have 3 choices.
1. buy a new adaptor
2. put a new voltage regulator in the adaptor (a friend did this for me)
3. use a converter so the adaptor you have will work in your wall.

O I didn't realize if it was branded to work with iPhone it would charge slowly. Thank you for your help. Next time I'll watch out for a "Works for the iPhoney."

Bump
I would like to know how it ended?
I have a same problem, the only difference is that i have stock HTC AC charger with separate USB cable (stock too). When plugged to AC it shows "charging(USB)". Tried different cables, same result. Tried two different AC adapters, but both were from NOKIA, same result...

This might help your slow charging issue
If the wall charger is causing your phone to charge in a USB state, the charge time will be very long compared to a normal AC charging state which I'm sure you are aware of. A cable called QuickCharge might help. It will enhance USB charging to AC charging. You can find it on Amazon by searching for 'QuickCharge'. It's the 2nd or 3rd item down.

What USB cable to charge GN?

Guys, I have my normal charger at home which works fine. Here at work I have a fairly new (but cheap) USB cable. At work the charge never goes up, it stays at the same percentage all day. It charged my Optimus 3D fine.
If I swap it for a colleagues USB cable (came with his Windows Phone) it charges fine (same USB port or USB ac adapter).
Is there a certain type of Micro USB cable I should be looking for that's not stupidly priced? (in the UK)

Coming from an Iphone I didn't have any spare micro USB cables so I went to a computer store and bought 3 store brand (cheap) microUSB cables and they all work fine.
The only thing to take note of is some wall charges are seen by the phone as "USB" and not "AC Charger" and thus will only pull in 500mah which is pretty slow. If you install battery monitor widget by 3C it will tell you the amperage coming in and if the phone sees your connection as USB or AC.
I discovered my 1amp apple USB brick does not charge higher than 500mah only my samsung one does that came with the phone.

yeah, but if I use the same USB port or the same AC plug I don't understand why 1 cable will charge fine, the other gives just enough to keep it at the same percentage all day?
