I still don't think people understand. This devices needs more output then a usb plug can produce. Think about it this way, would you charge your laptop computer off your desktop usb port? The XOOM requires a 12v charge, just like your laptop.

wont it be able to trickle charge... when in a pinch some charge is better then none at all

What don't people understand about this. A USB plug in a computer might only be able to produce 500ma, but you can plug that SAME USB cable into a wall charger that uses USB and it will charge fast as hell. The iPad does this. All Android phones do this. It makes it so you only have to carry one cable and maybe a small wall plug.

guess you missed prev poster point ... if you solder on a charging plug it doesnt mean you need to remove the other plug have 2 plugs on one side

You are right i miss read it

after some reading usb 3.0 delivers 900ma
and it looks those usb charger blocks deliver upto 9w at 1.8a

It is hard to say if it will work. Since I don't have my Xoom yet, I can looking at the output rating of the wall charger. Maybe someone can look at their wall charger and see how much output voltage and current it produces. If it's higher than 5V, the USB might not be able to charge it. If it could charge it, it would be better to have a USB cable that has one end split into two connectors, one with the circular connector, and one with the micro USB end.

Here you go.

looks like my usb 1.0 charger (from htc (ancient thing)) delivers 5v at 1amp
wondering if newer chargers deliver more. spec sheet of USB 3.0 says it can deliver 9 volt at 1.8 amp
hopefully the EU classifies the moto tablet as a telephone then its obligated by law to have usb charging ability

The iPad charger delivers 5v at 2 amps over a USB to 30pin cable.

Thanks. I just decided to glance at the Xoom teardown. From what I saw with the hardware, I don't think it will be possible to use USB to charge it. The battery alone is 7.4V, so there is no way to charge it with 5V unless the Xoom had a DC step-up convert. The teardown only lists a step-down converter which probably steps the battery voltage down for all of the components in the Xoom and has nothing to do with battery charging.

Does it require the same voltage to do a trickle charge? From the research XDA members have done so far, the Xoom charger requires 1.5A, USB puts out .5A, that's not too far off if we just want trickle charging.
The battery is 7.4V but 5V isn't too far off either.
Does the market app SPARE PARTS work on the Xoom, or some other charging monitor app?
Maybe someone who already has the Xoom and knows how to solder can frankenstein a USB charging adapter? Make one end fit into the charging port of the Xoom and the other end fit into a standard micro USB plug.
This way, you carry your normal USB cable for data transfer but if you need to charge, then you plug the USB plug into the adapter which plugs into the charging port.
BTW, can someone please clarify that the charging port IS THE ONLY WAY to charge the Xoom? Someone said on here that the docking device has a USB plug that will charge the Xoom thru the USB?

Spare parts works fine, so does battery monitor widget. The dock uses the 2 metal pins between the hdmi and charging hole.

My HTC charger outputs from the AC adapter to microusb at 5V and 1.0A, which is as high as I've seen with other phones and chargers.
The Xoom charger appears to output 12V at 1.5A.
I'm no electrician but that does seem like a pretty big difference. 140% greater in and 50% greater respectively.

A lot of armchair electrical engineers in here. Tell me, what would you gain from creating your own proprietary usb charger? You'd still have only one of them and you couldn't use it on anything else.
Has anyone stopped to think that it's very highly likely that the usb charging pins aren't hooked up at all inside the xoom?
This forum is the biggest group of whiny people I've ever encountered, and I once accidentally walked into a GoP fundraiser.

Well the current rating is only part of the equation. Think of the voltage as the pushing force for the current. The Xoom has two Li-Po packs (two batteries) with a nominal voltage of 7.4V. It really depends on the battery, but in general for Li-Po's, the minimum voltage for this battery will be something close to 6V. Li-Po's require specific ways of charge with min/max voltages and certain currents. The minimum battery voltage cannot be overcome by the 5V from USB, thus it will not charge the battery.
If anything, the 5V could power the device, but it wouldn't charge the battery. I would bet that this doesn't work. The power jack on the Xoom probably goes into a regulator that reduces the 12V into a lower voltage that charges the Xoom.

I don't see how you see it as whining, we're just figuring out how to get things we want ourselves instead of waiting for the manufacturer to do it for us
Most of XDA's reader probably have some kind of techincal/engineering/IT/industrial background. Nothing wrong with pooling our talents to solve manufacturers' shortcomings.

USB Charging
Just tried to charge it VIA USB and wall charger with USB port & this is the result.

A doubt about htc charger.

I have an hd 2 and its a used one when i bought it. So i dont get the original charger. I got a samsung charger @ 5v, 700ma. But when i connect it, the phone shows usb detected. Though its charging, its pretty slow, i think the usb mode makes it. Taking only few 100-300ma only. And the charging takes long. I know htc need 1amp charger. But i cant get it here. So i decided to rip the charger and make some modifications ( like grounding or shorting the data pins- the middle two) . So i need a little help. Any of you guys having an htc original charger pls help me. Howz the data pins connected in the original charger? Are they shorted together or they are open? Or they are grounded? Pls help me those who know abot it. I want to make my charger form usb charging to default charging. It badly needed

That's weird. I've got original Samsung 0.7A charger here and HTC Desire HD does detect it as charger aswell and takes 1A from it. Shortening datapins together does usually convince most of phones that they are connected to wall charger. Maybe it's not the case for HD2.

Samsung Galaxy Phone Rapid Charger Modcheck this thread few under yours... speaking of shorting data pins.

HD2 is same as most, requires 2 data pins to be shorted together (2 inner pins).
Easy mod on most charger units. If charger is a cheap china job, the quoted 700mA figure could be optimistic ... temporary mod it by shorting data pins together & see how it performs ...

But there are 3 pins and not 4. So which ones are the middle?

can anyone confirm if it worked for them? I made an adapter by shorting both data leads, but it didn't work for me. My phone will charge when switched off, but when it's on with both gps and data running, it barely gets enough current to charge the battery. Only my original cable works.

What device?
Signalling a dumb charger with MiniUSB (as opposed to MicroUSB) is less standardized. On most MiniUSB devices it's done by shorting pin 4 to pin 5, but it varies.

I could be wrong about this (someone please correct me if I am), but I believe the transformer inside the charger will need physically replacing if you're going to be pulling more current from it. If it's not too much over the charger's rated current it may be ok, but I've burned up more than one of them by hooking it up to something that draws more than what they were designed for.

Depends as part of the reason of the mod is to achieve full power draw of a acceptable rated charger by making the phone think it is connected to HTC charger & thus charge at mains rate of 1A or a little above rather than USB standard of 500mA. Most chargers of reasonable quality will supply 800mA to 1.2A & if you buy wisely a bit higher.
Issue arises on cheap china chargers with false specs that actually only handle 500mA & perhaps 800mA max for short bursts but when these are forced to supply more will fail.
A good quality charger will have no problem supplying full charge to a HTC handset ...

A good example - getting a non-iDevice to pull its full rated charge current from an iPad charger (charger rated 2.1A, but nothing but iDevices will pull any more than 500 mA from it without modifications.)
A good example of cheap Chinese chargers - the "1A" chargers carried by Monoprice. They're good for 300-400 mA at best. You won't burn them out as it's a fundamental current limit setting of the SMPS chip, but the voltage will droop if you try to pull too much out of it. It's the only Monoprice product I've ever been disappointed with.

sorry about that, I have the HD2. if I use the replacement cable with both data lines I shorted, it never charges when the phone is running. but if I swap my original cable the phone charges normally.
it's as though it ignores the shorted data lines, or maybe the HD2 doesn't really work that way?
I'm worried because my original cable is beginning to show signs of wear and tear.

Car charging (or not in this case) how to monitor?

Little help chaps.
Ok i've just bought this http://www.ebay.co.uk/itm/390566738301
I presumed (not sure if rightly or wrongly) that it would be sufficient to charge my Nexus 4
I'm using an older usb cable I've got to charge it in my car however if i'm using navigation then the battery still decreases.
I've got a funny feeling that the cable is the culprit but i'm not 100% sure.
Is there anyway to monitor how much juice your phone is getting from the charge?
P.S in the battery monitor screen it says AC not USB
Thanks in advance for any help
Stret

Battery monitor widget pro. It monitors the mA that's being used, mV, etc. Maybe the phone is pulling more mA than the charger is supplying.

You need to go into your battery settings/status while your phone is plugged into your car charger.
It will show one of two statuses:
Charging(AC) and Charching(USB)
If it is showing charging(USB), then the phone is detecting a false data connection. This can be solved by taking apart your USB charger and soldering the middle two pins of the USB. These pins are the Data(+) and Data(-) pins. I attached an image of the two Data pins soldered together on the usb charger.
If it is showing Charging(AC), then your USB charger is not pushing enough mA to charge your phone. Most cheap car USB chargers are in the 500 mA to 700 mA range. The stock USB wall charger that comes with your Nexus 4 is 5V 1200mA.

Hard to say. From my experience, you get what you pay for. A USB charger that cost less than 2 GBP seems unlikely to support the kind of mA throughput that the Nexus 4 requires.
Some ways to check this are to check the power supply and draw through a battery monitoring app, use a different USB cable or the USB cable that came with your Nexus 4, or take apart the USB charger and inspect the hardware to see if it actually is built to support a 2A supply. That last one is a bit of a headache.
Here is an iFixit teardown of a similar USB charger which goes into detail about some of the working parts of a car USB charger.
To quote the final part of the iFixit teardown:
Quite simply, the device is a rebadged 500mA or 750mA USB charger at best. It is NOT 1A capable, despite what the sticker on the body says.

No problem! You should try and remember that the Nexus 4 is a pretty sophisticated piece of hardware. I'm not advocating that you go out and spend 20 GBP on equipment, but you don't want to use a cheap generic piece of trash to interface that electrical connection. The build quality of your charger can put your handset at risk to being damaged by electrical shorts and/or heat.
I would liken it to parking your sports car in a cheap parking garage on the bad side of town. Sure, you can do it, but there are risks involved!

1.8 amp car charger

Reading from the AC adapter, this thing can charge at 1.8 amps. I'm doing some research on car chargers that can output 2 amps to the phone via a USB cable, but the trick is getting the phone to pull more than .5 amps from a car accessory outlet. So far I haven't had much luck. There seems to be a lot of info on ipad stuff, but not much in the way of high powered Android devices. So I thought I'd start a thread about compatible car chargers that will allow a full 1.8 amp pull from my car outlet, and see what you guys and gals think and have tried. I've attached a pic of my current setup. It's a Proclip holder on a 2012 Mustang. I've used this same setup for several previous phones (S2 Skyrocket and S3). The holder itself is adjustable to accommodate various phones with cases.

Data pins need shorted together, either in the USB cig plug, or some micro USB cables are this way...

Additionally, the USB cable you use needs to have thick enough power wires to support 1.8A charge draw. Many USB cables use 28 AWG wire for the data conductors, and then you get varying degrees of wire gauge for the power conductors depending on manufacturer. Some people use 28 AWG for both, some use 26, and good cables are made with 24 AWG wire. The thicker wire gauge means less resistance so less power is lost and more can be put into the battery. To pull a proper 1.8A the phone probably should have 22AWG power wire in the USB cable really...

I have a custom 5 inch up angle micro USB cable I ordered from www.usbfirewire.com. It is a very thick wire, thicker than the charging cable the G2 came with. The one in my pic is probably not thick enough for a 2 amp charge.

Spot on. FWIW, the LG OEM cable is 20AWG on the power wires. This is the only viable explanation as I can't get the OEM wall charger to work with any cables I have sitting around (24AWG at best).

So would we be better off just using the factory charger with a power inverter or is there an actual car charger that will work?

Provided you short the data pins in whatever car charger you buy (if they arent already) and you get a cable with beefy power conductors then you should be able to draw 1.5-1.8A of power through a car charger. You have to make sure the car charger will do what you want though, many 2A chargers also have 2 ports to plug into. What they don't tell you is that each port is limited to 1A and both together will give 2A draw, but not to charge one device. The car itself also may limit power to the charger as well, I know my car specifically says 1.4A max through the cigarette plug. So it is possible to do, it is all just dependent on so many other things that you have to check off the list.

I like the Powergen dual 2.1A USB charger I got off of Amazon. Has served me well. But really, anything 1.8A+ that's quality will do. The trick is going to be the USB cable. Still trying to source one from a reputable site, but you want something with 20AWG for the power. If I find something, I'll post it. Thus far I found two sites, kinda obscure, but not thrilled that the shipping alone costs more than the cables which run $6.

I suspect the phone can detect the charger capacity because my OEM LG cable works on both the Apple and Non-Apple ports on the Powergen charger. Since that's the case, the phone doesn't seem to care if the data pins are shorted or not. And the Powergen is advertised as 4.2A total, so 2.1A per port.

Are you certain that's not just the data side that is 28awg? Very surprised you can pull 1.8A at 28awg.

Doesn't that come with the same Amazon branded usb cable you can get by itself? Take a look on the cable. A lot of times they label the wire gauge.

My OnePlus One melted!!

I just got a new OnePlus One over the holidays. I've noticed that periodically it was getting very hot when I was charging it, both when using a car and wall charger and multiple different cables. On Saturday night I left it on the charger overnight and in the morning the phone was melted around the charger cable! Check out the pics below.
Only thing worse is that OnePlus says that it's likely because I was using a 3rd party charging cable (from my Samsung Galaxy S3) so they won't provide a refund or replace it. But they will let me pay $350 for a new mother board. So I'm out $400 and a brand new phone.

Normally using a different cable and charger wouldn't have such an effect. I know many friends who use aftermarket cables and chargers built for different phones and their phones are fine so I take that cause with a grain of salt.
Having said that, did you do any modifications to the phone, whether it be software or hardware? When it was getting hot, did you do anything about it?

No, I just got it. Didn't root or anything. When it got hot I rebooted the phone .. what is strange is that it didn't seem to always overheat. But it happened more than once on different chargers and cables.

I've been using a Samsung charger and cable that came from a galaxy s4 on so many different phones and nothing ever happened to them. Even have charged my one plus one with it. It was charging very slowly so I just used the one it came with and it charges at full speed.
Try talking with a different person and not mention using a different cable and charger. Its definitely not because of that. You deserve a new one.

Probably due to using a cable that isn't rated to carry the current that the charger outputs and that the phone draws.

kinda like using a skill saw on one of those two dollar 12' household extension cords. everything gets hot.

It's really odd. The One itself uses a pretty powerful 2A charger :/

Hmm... did you charge your phone directly when it was still hot?

Thing is if a charger comes rated at a high output amp, they usually ship an appropriate gauge cable for it. I'm pretty sure Samsung would've shipped a 28/24AWG Micro-USB cable with a 1/1.5/2A (maybe not 1A) charger to prevent the wire from melting out. My guess is OP probably mixed cables with chargers. It's common to have multiple Micro-USB to USB cables these days given most electronics support. Most of the time these cables are 28/28 gauge. I am guessing OP used a 28/28 with a high amp charger (although the standard S3 charger seems to be rated at 1A from my search results). Seems like OP used the OnePlus One charger rated at 2A with a cable which was probably rated for 0.7-1A (that seems to be the standard S3 charger's output).
Can we get more info on what charger and what gauge cable was used OP?

I was just trying to bring the odds of this happening to my phone closer to nil with a possible scenario so I could sleep better tonight after leaving it on charge :silly:

Everybody got a phone charger and cable with their phone right? Why would you use some other cable or charger then? Especially now that it seems that its possible to have your phone melt with using 3rd party equipment, why would you still not use the charger/cable that came with the phone? To me thats like buying a truck, putting different wheels on it and getting pissed when something happens.

Convenience of not carrying that same cable everywhere? OP seemed to be using chargers at home and in his car, so it's easier to have a cable for each of those chargers.

Maybe the phone is defective. I hate it when OEM'S being cheap.
C'mon One Plus. Don't be like the ****ty samsung. Make the difference

Hey, you can easily and realitively cheaply change the plastic back cover on the OPO. Just purchase an original back cover replacement from OPO. It comes in various colors and even in bamboo. If the metal plug is still ok and only the plastic melted, you should be ok and still have a 100% original phone.

Leaving it on charge overnight isn't good for the battery anyway, the more time a lithium battery spends at peak voltage (4.2v) the faster it degrades.

WHen you don't have the official charger/cable with you, I ALWAYS tell people to charge it via a computer USB port (0.5 A) instead to be on the safe side (with whatever cable you plan to use).
And never mix/match your USB cable/charger ports.
