Hello all, I purchased a WCP-700 from eBay but I think the AC adapter was aftermarket. When I plug it in, the power and battery lights flash continuously and does not charge my phone.
I tried the AC adapter from my Dlink router and it seemed to resolve the issue: the phone started charging normally.
Now I need to find a spare AC adapter. If you own a WCP-700, could you please check your AC adapter and confirm the correct output voltage. I believe it should be 19V 05A, The AC adapter I received did show 19V 0.5A, but it doesn't work.
What's odd is that the AC adapter I tried from my dlink router is only 12V, but it seems to work.
Thanks.,
I can confirm that it is.
Output:19V 0.5A

Hi folks,
Love my MDA II, but I can only get it to accept a charge when my laptop is turned on. If the unit is not plugged into USB or the laptop is not on, it won't charge.
What am I doing wrong?
Finally, I have noticed the last few days that the wall AC adaptor has not been plugged in, yet the MDA has been charging through the USB when the laptop is on.
My question is what is the point of having the AC adaptor if it serves no purpose.
I rechecked and pulled the USB and plugged in AC adaptor. No charging takes place.
you are doing nothing wrong. the power thru the usb port comes only when the laptop is powered up (whether the AC power is on or not ).
In other words u can
1. charge it from your laptop's battery but the laptop has to be turned on and it does not matter if the AC power of the laptop is plugged or not
2. you can charge the XDA directly thru its own AC adapter, independent of the laptop
The AC adapter does have a use, you can either use it in conjunction with the little square dc converter that you get free in the box to charge up the xda without the cradle, so you could have the cradle at home and tyhe AC adapter at home if you wished, and if you plug the AC adapter into the cradle you can charge an aditional battery, as the additional battery can not be charge via USB, Maybe xda developers may be able to frig the cradle to charge the additional battery in the future (hint hint)
Cannot charge xda executive with car charger ,when connected nothing happens light does not go red and also the connection icon does not show
make sure you dont have a faulty charger... dont know what you are using but i believe most people use the cigarette lighter to usb converter and then just use the usb cable... also have you tried pressing the on and off swith with the charger plugged in ?

car charger
Hi and thanks for the fast reply mate <yes it is a new charger from o2 .
No i have not tried the on off with the switch ,but would i still be able to charge when i am using tomtom
Whell....I use the cigarette lighter to usb adapter and usb cable ...at times i have had to quik press the on/off swith and at times plug and unplug the cable to get it to charge ....I used this as a "jump start" method only and no problems after that with using it whillst on charge (even with tomtom)..... other than that you may have a faulty charger or fag lighter to usb adapter (I never seen what a o2 one looks like).

Is the charger one especially for the exec?
I found normal usb chargers for phones like V3 or a GPS charger cant supply enough current to charge an exec.
hi, yeah i have had this problem, and so have a few of my clients, seems that not enough juice flows through the non branded versions, unlike from o2's or Brodits cables
I found that a regular USB cable into a Cigarette Lighter -> USB Socket didn't work until I joined pin 4 to pin 5 on the USB B Mini plug. All of the adapters I had that worked, but only powered (no data, i.e. Brodit and mains adapter) seemed to have pin 4 joined to pin 5 (pin 4 isn't normally connected at all). Once I did that mod it worked fine.
Cheers,
Steve.

Orange shops carry a charger intended for HTC manufactured devices (i.e. the SPV C500/M500 range) which works fine. Only £9.99.
So I visited my local Walmart and discovered a car charger, designed for Blackberry 6200 through 7500 and Motorola RAZR series phones.
The connector is the same, mini USB B.
$25,000 Question: Can I use this to charge my TMO MDA? Same connection, just worried the voltage or wiring might not be the same.
The AC chargers that came with my Razr and MDA are the same voltage-wise (5V) but not the same Amps.
MDA is 5V 1A, Razr is 5V 0.5A, they are not the same
However, it shouldn't damage the battery, just charge slower.
Just so you know, USB ports output 5V at 0.5A as well.
Edit: Sorry, I realize I completely changed my post, but didn't want incorrect info out there.
Thanks...I figured that, but was just making sure.
I got it in case of emergency...I almost always charge via USB; just leave it plugged in all day.
But you never know.....
Thanks!

Don't expect it to charge if you battery is below 30-20% charge. I'm not sure why this is an issue but it has bitten me in the rear once already.
Does anybody know why it's a problem for "less-than-1amp" chargers to charge back from the low threshold?
boxwave.com sells a 1 amp car charger. It has a USB port, so you just use it with any cable that normally plugs into a USB port. Since my Globalsat GBH-820 BT adapter came with a cable with large USB at one end, and _two_ mini USB at the other end, I can charge the GBH-820 and my 8125 at the same time.

That's not true,... if you use the VersaCharger like I do. This is where I learned of the "charging only" cable that Boxwave sells (how conveinent) and then they sell a Sync/charger for USB only. I have a Boxwave VersaCharger that I can't use without buying their "cable" to make it charge the 8125. I found this out because I have a Belkin retractable sync/charge cable that doesn't work with the VersaCharger as I had hoped. The cable that you have may work with 1amp charger but it probably won't work with theVersaCharger.
What is the output on the "min-usb" connector end of the cable? This sounds like the cable that I need for the 2 devices that I use.
...I wonder if they are putting some electronics in the cable connector...?
I bought the bundle that had a car charger (I have the regular; not the high output; not the Versa) and two mini-Sync (retractable) cables. I got caught by the fact that one of them is "charging only" when I was trying to use the "charging only" cable between my laptop and my TI-84plus calculator. I switched to the mini-USB cable that came with my calculator, and it worked fine, as did my phone with AS. That's when I looked closer at the two mini-sync cables and noticed that one was for "charging only". So, that mini-sync cable (the charging only) stays in the car, and works fine for charging my phone or my GBH-820. The really odd thing is that the "charging only" cable looks "thicker" than the one that works for syncing. Maybe lower gauge wire to help the higher current flow easier.
I have also used my other USB-miniUSB cables with my car adapter. E.g. the cable that came with the phone, the cable that came with my TI-84plus calculator.
My Bluetake headphones came with their own USB cable that has, for lack of any better term, an ultraminiUSB (or some kind of proprietary connector, cause it's not marked with a USB symbol like the other cables) plug at the end. I just plug the regular USB end of that cable into the car charger, and it charges the Bluetake's just fine.
Excellent car charger for Wizard
I have purchased and used the "Ecovell 4x USB" adapter on both a Wizard and a Universal. It provides a 2 Amp output which is equivalent to the AC adapter and works with any mini-USB cable. It will charge a Universal from absolutely dead which I have not been able to do with any other adapter. Here is the link to the item on Yes Depot:

I've ordered from them and the service was OK. I haven't seen the item available anywhere else.

so i updated to 2.2 today, phone charges with my wall charger just fine, i get in the car and the car charger wont charge the phone for some reason. i restored a nandroid of my CM 5.0.6 rom and plugged the phone into the car charger, and oddly enough, it started to charge.
having the car charger is a must for me, is there anyone else with this issue? or any possible solutions?
no one else had this issue?
weird.
are you referring to the car dock or connecting your usb to a usb cigarette adapter?

usb cigarette adapter
Sounds like it's under powered and isnt' registering it. if you can try a different usb cable / cigarette adapter.
After trying a few different roms and yesterday my N7 will no longer charge when connected to an AC charger, it still works when connected to a pc.
I'm using the same charger/cable that has been working for months and the charger works with other devices.
I have tried factory reset/wipes and full reinstall. I have also tried restored backups for a few days ago which no longer work either.
Any one know why it would work from pc and not AC? Could it be a hardware problem unrelated to rom changes?
your tablet charges through PC; are you using a USB slot hooked up to a higher power connector (i know some motherboards have those)
I've worked it out. The nexus AC charger has slide on pins for countries different GPO configuration, the head i had on the charger wasn't clipped in all the way and was causing the charger to work intermittently.
