There have been quite a few postings here on people having problems charging their XDA with thrird-party chargers originally built for the XDA I.
Add me to the list I"m on the road and can't get the damned thing charged using the charger.
However the good news is, that the problem is not the cable (or the connector for that matter). Right now I'm in the internet cafe using the USB-connection to charge the XDA II at least a little. THis is working!!
My third-partz charger is a power supply with a USB-socket, that connects with this charge-sync cable. But, its not working! This leaves two possibilities:
1) The power supply is providing a lower voltage than the XDA II requires (something less than 5.0 Volts, mazbe 4.7?). I can't check this here, but if someone with a similar problem could measure his charger voltage using a multimeter, we might find an answer. Pins to check on this site under "connector".
If this is the cause, it won't help me here, but at least we'll have the problem solved.
2) I noticed in my charger, that the USB/pins 2 and 3 ( Data-H and Data-L) are unconnected. Potentially the XDA II has an issue if these lines are floating whilst power is applied to the USB-bus. I don't know if we can check this easilz,bu if someone has an Idea?
Greetings from the Maldives 8) Sun, warm, great, but no power for my XDA!!!
mobile charger
I'm using a nokia charger, and the supplied adapter and it seesm to work fine.
MDA/XDA II Pinout - Charge Issue Resolved!!
Being back from my vacation, I immediately got into figuring out why my third party charger was not working, though the MDA II would charge through the same cable when connected to the USB-bus of a PC.
It was a wiring error in the USB-cable after all!
To figure it out I took that little adapter that comes with the original charger apart. Though the MDA/XDA II has the same pinout as the MDA/XDA I, there is a major difference in that not all GND pins are connected together inside. In order to charge, at least one of Pins 16,17,18 must be connected to ground. The grounds on pins 2 and 5 are not connected to the internal charge circuit. TO make things worse, the MDA/XDA detects an external charge power source when pin 2 is GND and Pin 22 is +5V - so the light goes on, but it still does not charge.
On my cable the USB-shield was connected to pin 18. When connected to a PC, the shield was connected at that end to Ground and all went well. On my charger supply, the shield was not connected, so it couldn't charge.
I just rewired the connector and see there it works!
So, if you have the same problem, and are handy at the soldering iron, there is a solution! For those making/selling those USB charge/sync cables, get it right the first time!
Is it safe using a Nokia Charger ?
My Nokia travel charger is rated at 6.2 V, not 5.0 as the one supplied with the XDA II
Regards
Michael
Yeah! But watch out anyway because the volatge is not the only thing to check before charging a device. The right voltage but a bad amperage can cause lots of damage...
Using the Brando USB charger woukd actually DRAIN the battery when the bar reaches yellow....
Using a Nokia charger
The Nokia is rated at 6.2 V 720 mA, the original charger is 5V 1 A.
If I understand my physics right, the XDA may draw more current that the charger can handle, so AMP vise, the danger is on the charger ?
Not that I belive that the XDA would really pull 1A, but you never know.
It would be really nice to have just one charger in the travel bag..

Suggest a USB Charger and source.
Can anyone suggest a usb charger cable and source in the UK for an O2 XDA 2 as the one that I have currently does not charge at all despite the light saying so.

This was the effect I had. Its a mistake in the wiring on your cable.
Thanks,
What I am really after is to find out if there is a place to find a USB cable that will work right out of the box/dodgy package that it comes in. I am not good with soldering irons or electronics and would like to buy one that is wired up correctly to charge my XDA II.
Cheers.
I got a Wing, and it came with that big ass charger that says use only for wing, mda, and dash. Well I JUST now read that on the charger. Its not that I've been using this charger on other devices, its that I've been using my OTHER usb chargers to charge my Wing.
Is this bad?
Im currently using the charger from my BlackBerry Pearl (well, until I found the Wing charger again), am I in any way damaging my battery life? Or perhaps not charing as fast as I should?
Im just curious why you can only use that charger on those phones, and if its so picky, if I'm doing harm using other chargers.
If anyone knows please do tell.
No worries. The tag you see is more of a marketing decision than a limitation of the adapter itself. You can use that safely and normally on any device that requires a standard USB charger. And vice-versa, you can use any standard USB charger to charge your phone with zero adverse effects.
... well, as long as it's not a REALLY cheap charger.
right on.
I didnt know if the "wing charger" had some type of extra output to help charge faster or something.
I use a Motorola Razr car charger and it works just find.
I have noticed once or twice, for some odd reason, sometimes the Wing wouldn't "recognize" when I plugged it in with a razr home charger... like it wouldn't show that it was charging ... but maybe it was just a crappy charger.... I don't know. But I have charged it with a Blackberry 8000 charger with no problems.
I always wondered myself whether or not it would be a problem... bc the Wing's usb plug isn't a "standard" usb, but it's got a weird shape.... but I still think its just a marketing BS technique to get you to buy THEIR like $40 chargers.
Actually it may not damage your device, but may damage others using it the other way around.
Moto RZ charger is 850MA Output
T-Mobile Charger is 1A
Output
After charging my raz on accident with the t-mobile charger it seems like it can no longer hold a regular constant charge...
This also is in effect with any itips/igo adapters there are two tips for the charger, one raz USB, and one for t-mobile higher powered devices
I'm using a Motorola Q charger in the car just fine. Which is nice, because it can also charge the GPS receiver that also has a mini USB jack.
Charging your wing with any min-usb charger (such as the standard motorola ones) is fine...
The only problem you might face is... if your phone is *completely* discharged, you will need the stronger charger to recover it... the Razr chargers and the like don't seem to have the strength to revive a completely 100% dead Herald

I actually experienced this with an MDA (wizard) ... it had been uncharged for months, and I tried to charge it with a razr charger, and after sitting on the charger for like a day ... it had zero charge.

DAMNIT!!
I did this too!
I had a wizard I was going to use before I got my wing. It wouldnt charge, I thought the battery was trashed, so I bought a new one.
Though I only spent 10 bucks on the battery, I wish I would of known. Though I bet a real charger for it would of been more then the battery.
Hi,
I am looking to buy a car charger for HTC Fuze
There are so many listed like at Eforcity and BargainCell
would anyone of them is fine?
Is there a decent place other than those two? Above places are just charging more on shipping than the actual cost of the charger
Thanks
The easiest way would be to swing by an ATT or Verizon store.
I do have several and they are all rated 5 V (rarely you'll find 12V) but use one of these. They are pretty slick because you can charge ALL USB devices and, if you travel, it's a "one-for-all" device (meaning I can charge my headset which has a USB cable, iPod Nano and the phone.
http://www.daydeal.com/product.php?productid=10892
If you travel a lot you may look into one of these as well
http://www.bixnet.com/usbbatterybox.html
There is also one which does both, AC and cig. input to USB output, a little bit bulky though, but I couldn't find the link right now.
how is that compared to this one
http://www.amazon.com/Charger-Generation-Antenna-Booster-Google/dp/B001LP2ME0/
Comparison:
They both charge
The one you listed is cheaper (even incl. shipping)
Not that flexible
I don't know what other USB devices you have to charge, meaning if they have different cables for different devices, I do.

the reason I mentioned that one was I could not find anyone for 5V
all are 12V
in your first post in this thread you mentioned you have all 5V ones
http://www.dealextreme.com/details.dx/sku.13522
i bought 1 of these. works great. has 3 inputs and 1 usb port.
My solution to the car charging problem has been a power inverter. You can charge your phone using your house charger, and plug in other stuff at the same time. The last one I bought even had a couple of USB ports so I can use a standard USB cord to charge various devices. Also handy for plugging in my laptop, dvd, tv, etc.

A car's battery is 12v. So when they say 12v, they are referring to input. It should then regulate that 12v to 5v (USB spec). If you are worried that this one does not have this regulator, spend a few extra dollars and get a better one.
A car charger should have a regulator anyway, because your car's alternator can output up to about 20v. For USB devices, it needs to be regulated to 5v, or damage may occur.

types of usb connectors
Hey guys, tell me please are there two types of USB connectors to TP ?
I mean the one is like a regular mini USB and the other is an asymmetric one ? Because i ordered ones a car charger from ebay and got the one with the mini USB connector although my TP has the second one.
This is the one i think of buying http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250434240310&ssPageName=ADME:X:RTQ:US:1123
TP has a special usb head for multimedia etc, but for charging use, your item would be ok.
have not had a look at your ebay link (at work) will go home to confirm
Old Motorola Car Charger
I use the car charger from my old Motorola Razr. It has a charging light and charges quickly, however, the Razr will not charge from the Fuze home charger...David.
It seems that there is an important issue about car chargers, which isn't mentioned in this thread. The HTC car charger is 2 ampere, where othere chargers (like the one I bought on Ebay) or only 0.5 ampere. This is problem when having heavy load on your Touch Pro. It then actually still drains battery while charging.
I'm in the UK and want to save $20 on the charger
I have a couple of Micro USB wall chargers that i use on my blackberry. They will fit the N1 and plug straight into the wall. Would they be safe to use, to charge my N1. (These charges are rated 750mHA).
I know the N1 will be supplied with a micro USB cable. I also have an IPhone wall socket plug head, the ones where you just put the USB cable into the plug and then it goes into the wall. Are these safe to use too, for charging the N1?
Thanks
the Nexus one connector is standar microUSB and therefore will work with standard microUSB cables and chargers.
So there is no type of resistor or transformer in the official plug head? ... to restrict power. I thought there would be as my blackberry charger has a 750mha rating on it.
I can understand the USB cable will work as its a limited power output from a laptop port. But just wanted to check the official wall outlet plug current isn't being restricted. The last thing i want to do is fry my new N1.
Cheers,
Just plugged mine into my old nokia classic micro usb and it is charging fine
The specs for the wall charger are 5V and 1A.
http://www.htc.com/europe/product/nexusone/specification.html
do what i did. remove the charger from your basket and use the supplied USB with an old htc charger if you have one. If not get one for a few quid from ebay why spend $20 when you can get one for $5 odd from the market/ebay.
I can only speak anecdotally, but I used a Blackberry Storm charger and nothing exploded
this mini, micro, A B stuff is annoying. to clarify for my simple mind, will usb cables that fit into my G1 fit into the N1? or is it a different size?
Last year, Micro USB was decided as the open standard for cell phone chargers, so this should be replacing Mini USB as seen on earlier phones (BlackBerries, G1) in instances where the port isn't.. some.. proprietary crap.

No. The G1 used Mini USB, this is Micro USB. The phone comes with a charger and USB (USB-A 2.0 to Micro USB 2.0) cable.
It's not propitary so it will work with any other charger.
It's a funny thing to find. It's too new to be widely available
I went looking for a car charger and a straight USB A->Micro B cable. The former I found by poking in all the packages for different phones until I found it (found a Samsung charger that uses it, although they did want nearly £30 for the damned thing). The USB A->Micro B I drew a blank - the more clueless salesmen tried to convince me that I was mistaken and I meant Mini!
I thought the blackberry used them but I looked in the pile of blackberry cables the local shops had and they were all mini. Even my local electronics store has every kind of USB imaginable *except* micro.
Edit: Found one! (might be useful for UK users). It's out of stock though... http://www.cableuniverse.co.uk/catalog/cables/USB-A-to-Micro-USB-B-Cable.html
Just so you guys know, not all micro USB's are the same. I bought a car charger from a local Tmo store last week (I forget what phones it was for), and although it "worked" when the plug was perfectly perpendicular to the phone, it had quite a bit of lateral play (which the OEM plug does not), meaning anytime it moved in the car, it would stop charging.
I returned it, and am now just waiting for HTC to decide to manufacture accessories for this ever increasing bundle of worry...
I am using a TomTom charger for my N1, also the HTC hero and the Motorola Droid chargers works to charge my N1.

Seems like it was just a poor quality charger. If it's a micro USB, it should be built to specific specifications. I already bought a few chargers (including a car charger) and cables (for work, home and travel), and they all work perfectly. Technically ALL micro USBs should be the same, unless the manufacturer didn't follow the standards.

Hah, just my luck; I pick up the one out of spec micro USB charger in the entire city!
Although, it must be that particular T-Mobile supplier, as I went to another store and test fitted the same charger, and it had excessive wiggle as well. Either that or my phone is just lame...
I just got a universal charger in Tesco for £5 that has changeable heads (Micro, Mini, Samsung, Sony Ericsson and Nokia 2mm)
Works perfect
- The cable is standard USB. You can use it to charge the phone from your PC, or use another micro USB cable or charger you have
- The Nexus comes with a US 2 pin charger that is dual voltage - works in UK and US. Just spend 50p and get a US to UK convertor plug.
- The charger is rates 5v 1A, so if you have another microUSB charger with the same voltage use that.
I find charging from the charger results in more battery life than USB. The only explanation is charge rate because USB is 500mA and the charger is 1000mA
PS. I removed the UK charger from the order too. You get the US charger regardless in the box.
Anyone else have any experiences they'd like to share using non-OEM chargers?
I use my HP TouchPad charger in my living room, as my HP Touchstone plugs into it usually. It charges the N7 at exactly the same rate as the OEM charger.
Just curious about others' experiences.
Oh....and is anyone else w/the HP TouchPad just completely spoiled regarding tablet prices? $250 seemed like a lot of money to pay, LOL.
http://saraoutlet.com/yxt-023-us-2-...for-apple-ipad-iphone-4g-3gs-white-35561.html
I use this, it charges my iphone, ipad, ipod touch, samsung, and now my nexus. I have one for the car as well that is 1A/2.1A.
the blackberry playbook 1.8a charger works really well. indistinguishable from the supplied OEM. available for $16 bucks or so in retail packaging.
I've used the same charger for my Galaxy SII. Seemed to do the job well and just as quickly!
I have a few blackberry chargers one is a playbook one and some other android chargers.. they all work just fine.
I'd love to know if there are any portable chargers that will charge the Nexus 7 without being plugged into the wall, so, I can charge it when I'm laying in bed or something, I have portable USB chargers that I don't thing would work with the 7 The Duracell Powerhouse USB charger and the Sony Media CP-ELS USB Portable Charger with 2,000 mAh Li-Ion Battery, I use them interchangeably with my iPhone 4S and Playstation Vita.
Okay, I went through my "wall wart" drawer and tried 8 chargers and 9 cables. I can't find any pattern to the results
There was one cable (skinny black generic USB) that didn't work with charger, and one charger (from a Kingston Wi-Drive) that wouldn't work with any cable.
The best cable was a white mini-usb (that I used with a mini-micro dongle) that had come with my generic 5000 mAH backup battery; it worked with *everything* except the Wi-Drive charger. The best chargers were the OEM ASUS charger, and a generic small black cube (1A) labelled "KIN"; those worked with every cable except the skinny black dud.
The worst of the working chargers were an "Innergie" dual laptop/USB power supply, and the generic battery backup. Those only worked with that white cable.
Honorable mentions go to an old Motorola RAZR charger (used with a mini-micro dongle) and a small Samsung phone charger. Those have permanent cables, and both worked.
I couldn't pick up any pattern in terms of amp rating (obviously, the lower amp chargers will take longer). It seems to be "luck of the draw".
I've tried probably 4-5 different chargers including a Motorola wall charger plugged in the wall, and also plugged into a power inverter in my truck, a motorola car charger and an oem wall charger and have no issues with any of them.
iPad 3 charger compatibility
Can anyone confirm if N7 charges using the new iPad 10W charger? Mine only supports the charger that came with it. Does that mean that the usb port is broken and I need to replace it or is it the way all the units behave?

The Nexus 7 does not show charging when plugged into any of my OEM/aftermarket Apple chargers.
It does not appear to matter whether I use the USB cable supplied by Asus, or a standard commodity micro USB cable.
There is evidence from other users that the tablet may be charging at the 1A rate even though the charge indicator stays off.
I have not personally confirmed this yet.

I've had one of those OEM/aftermarket Apple charges blow up on me (not shrapnel, it stayed in the plastic casing), so I wouldn't expect much from those anyway. Have you tried with any standard micro USB phone charger?
Chargers that work:
- Motorola Droid Pro (hard-wired micro USB). Rated at 800 mA but seems to charge almost as fast as the OEM.
- Kin One (Uses any USB cable). Rated at 1A, works with every USB cable I have (almost; there were a couple that didn't work with anything). These are available on-line for less than 10 bucks:
http://www.amazon.com/Sharp-Standard-Wall-Charger-CNR1002/dp/B005IY428Y
http://www.aftermarketcellular.com/ic/CNR1002.html
This is nice and compact; I'm going to order a couple of more to have as spares.
- Motoroloa RAZR (hard-wired mini-USB, used with mini-to-micro adapter). Rated at 500 mA. Works, but probably pretty slow.
- Samsung (from unknown phone; hard-wired micro-USB) rated at 750 mA. Didn't test charge time.
As an aside, I have a 5000 mAh backup battery that I've used with phones and my Nook color (http://www.amazon.com/5000mAh-External-Motorola-Blackberry-Nintendo/dp/B004P8E612). It works with the Nexus, but ONLY with the mini-USB cable that the Power Bank shipped with. Every other cable I've tried chokes. It's intended for an iPhone and puts 6.5V across the power pins (with no load; this is about the same as the Kin) and pulls the data pins to 3.4V. What's weird is that I can connect a 2-conductor (charge only) extension in series with the working cable, so that the data signal never reaches the Nexus. If I use a 2-conductor cable by itself, the Nexus doesn't charge.

Compatable car charger
It's really disappointing to know N7 is so picky about chargers. Can anyone report on a working small/short car USB charger that is compatible?
You might want to check that your vehicle can provide 2amps from its cigarette lighter plug. Normal only utility plugs can do that.
