Hello,
I have been a victim of stolen bag recently.
Inside, among other things, was my original X1 wall charger, which is lost now.
At home I have a couple of other usb chargers but although they are 5V the Amber are different.
I know they work, but I prefer to use one closest to the original output for the wellness of battery.
(I slightly remember that the genuine charger was less than 1A)
Could someone pls check the original power adapter and tell me which exactly is the output?
(thanks in advance)

700ma. you don't have to keep close to the charger's specs other than the 5V. ampre rating is merely affects the speed of charging.
Just like how u charge from ur computer's usb port, you get maximum of 500mA /port anyway.

Thank you alvino!
Further to this question, can anyone tell me if a Blackberry In-Car Charger is OK with the X1?
Any usb port charger will work with your phone. Although, you might not wanna let your battery drain completely, one of the cells may fail and you'll get the dreaded "On button red light" syndrome... which I did. The main solution to that is to replace the battery. Considering the difficulties I've had, I'm sad I didn't pick a C905 instead
as long as it's 5volt it can be 1MEGA amp
amps are drawn not pushed
ohms law is
A = volt / Resistance
the device will draw as much as it require nothing more
It works just fine with my Zune charger, which is 5v 1.5A.
Ok, so I took my Inc on it's first run yesterday as a full-time GPS. It sat in the Verizon dock, plugged into my Griffin dual-port USB cig. lighter adapter.
It made the entire 3.5 hour trip, but when I got there, and removed the phone from the charger, it was at 9%. It had started at 100%. So, obviously, the 5V .5A that the Griffin outputs is not enough to run the GPS and at least maintain charge.
Does anyone know where to get a 5V 1A car charger? Unfortunately, most manufacturers don't even list the amperage output of their devices either online, or even on the packaging!
Thanks,
Doc

sounds like you might be best off with a power inverter and a wall adapter. or you could buy a car that has a 2 prong outlet in it like mine

As an EE that's really inefficient. Belkin USB Micro Charger does 5V @ 1A max. It's marketed as an iPhone/iPod car charger but it does work for the Incredible since it doesn't have any fancy charger lockouts. There is also a 2 output version with a 1A and 500mA plug.
anyone found an alternative car charger, I dont mean using the wall charger with an inverter
but a charger that plugs into the lighter plug?

I used this on my Palm Pre. It charges my Epic 4g, and I tried it out on the Nook Color this AM.
It worked just fine.

There's qutie a number of cigarette lighter adapters available that offer a standard USB port. You'd supply your own cable. Here's an example:
http://cgi.ebay.com/Mini-Car-Cigare...053289?pt=PDA_Accessories&hash=item2a0eed35e9
No, AFAIK, none of these will charge as fast as the standard NC charger. For that, you'd need to go thru the hassle of getting an inverter.
Monoprice has cigarette lighter to female usb chargers for $1.16 that you can use your usb cable with.

Larger, heavier, more cords, much more expensive (when compared to a $1 cig-to-usb)...
Just has to be able to push out the current needed. Otherwise it may not charge, or it will charge very slowly.
The Scosche reVIVE II Dual USB Car Charger for iPad has 2.1 and 1.0 amp usb outlets, I use this for plugging in my evo and nc. It definitely charges them both even while having all the wireless radios going and tethering with gps and both screens full bright.

Same issue here, I have a road-trip coming up this summer and I'd love to load up my NC with music and dash-mount it but it'll be a 14-20 hour drive (depending on the number of whiz breaks the wife and kids need) and I don't think I could push the battery quite that long and the inverter when wired to the radio creates quite a buzzing.

Are you using the Nooks specific cable on the 2.1A connection? I too am going on a trip soon, and would love a car charger that can actually CHARGE the nook while using it..
www.amazon.com/Scosche-reVIVE-Dual-Charger-iPad/dp/B003N7NO4Q
Is this the one you have? It looks nice and the price looks okay. Nice find. I also saw a wall plug dual usb version by same company on the same page, do you have any info on that one too? It would be nice to stream line travel chargers to a minimum, thanks.
It definitely charges both. Like I said in my previous post, I usually have both my Evo runniong and the Nook full bright display on for 50 minute commute, using TetherGPS, wifi hotspot, torque and bluetooth, google navigation pulling satellite imagery, and playing mp3s. Granted, it is slower to charge than without all that stuff running but my previous car charger would lose charge with my evo running just gps and no wifi hotspot previously.
I am using stock blackberry usb cables that I ordered from Amazon as well for $1.25 for a pair (google 'B001UC9NOQ', can't post links yet.) These are nice, thick cables that handle the charger great. I leave them plugged in inside the truck at all times. I have not used that Scosche wall charger, I use the stock chargers for travel that remain in my backpack, and I have other usb cables I use to charge at home. I would imagine it works just as well though.

Let us know if it works for you. An Amazon reviewer just reported that the Scosche reVIVE II didn't work on their Nook Color:
The nook color needs 1.9 amps, this can't do it. Scosche claims 2.1 amps but it isn't even close. It BARELY charges the nook if the machine is sleeping, when on, the battery charge goes down even while supposedly "charging." Playing video, it's even worse. On top of that if I try to charge a regular phone it puts out too much amperage on the 1 amp side and overheats the phone. Save your money, look elsewhere.
Click to expand...
Click to collapse
However, the reviewer may not know what they're talking about. A charger cannot put out "too much amperage." Too much voltage perhaps, but not too much amperage (current). A device draws only the current it needs.
An iPad needs an amperage around 2 A also. I got the Belkin Charge 2.1 made for the ipod/ipad and it DOES charge the nook color. It has a 12V plug with one USB outlet at 2.1A. I used the cable from the nook color obviously...
See, part of my worry is not the current output, but if the nook can actually communicate with these chargers and get a full 1.9A draw, instead of the detault 500mA over non B&N chargers...

I bought the same Belkin iPad charger from Best Buy. Rated at 2.1A. I used it with the B & N USB cable that came with my Nook Color. I used the 'Battery Monitor' software mentioned earlier here or on another post to compare charge current readings against the stock B&N wall charger/cable. The Belkin was charging right at 500 mA (NC was using ~450 mA, software showing +36 mA current). So somewhere the B & N cable & charger must have a unique way of determining that it is a B&N charger / cable and to allow the full 2.1A charge. I used the Belkin 12V charger on my TomTom and it allowed just over 1A charge, so I know the Belkin iPad charger is fine.
Yes, it does charge the Nook Color, if you are at 800 Mhz and minimum brightness running non-intensive applications--and it barely charges at that ~50 mA. It does turn the charge indicator on the B&N cable orange, and the status indicates battery charge on the screen.
I went from an OG droid to the revolution. The car charger i used to use for the moto droid was charging that phone very fast, just like the ac charger. Now with the revo, it's pretty damn slow. I tried shorting the data pins with some solder and the revo actually dropped about 200mv worth of charging current. Strange. I thought shorting the data lines together put the phone into fast charge but when i "cat /proc/kmsg" it says "charging at 0mv" even though it is actually charging at about 400mv as verified by a ammeter. My home charger gets "charging at 1800mv". Some strange stuff. I'm gonna try the ipod method of 2.8/2.0 unless someone else can chime in here. Thanx
I'd be interested in this also. I'm using New Trent USB battery pack and I want it to be acknowledged by the Power Manager as a fast charge source -- not the "computer connected USB" source it shows as now.
I use a store bought adapter, with the verizon/LG cord I got with the phone, and if I use Google Maps and Navigator, I lose power while I am plugged in. Glad to see I am not the only one with the "issue"
I figure its just the way the phone charges, not anything to do with any bugs or what not, so I never really worried about it. I just make sure I am fully charged before I need to use the power sucking apps.

On USB "computer powered" I've found maps and weather apps suck battery much faster than it can recharge. I noticed that the car adapter is detected as "AC Powered" -- even though it's starting off as 12VDC. I was hoping to use the external USB battery pack to keep the internal battery full while using the maps and weather in our boat --- but after 5 hours with screen on and battery pack attached at "USB Computer" recharge rates, the internal battery was flat-out DEAD, and the external pack was only down about 35%.
We just need to figure out what the data lines want to see for a "dedicated charger" type-2 charge connection which will yield the full 1800mv like the ac charger does. I'm working on this...hope i don't fry my phone's usb controller
My problem is, i don't have a charger that shows up as such. My friend's last night did, i may try to get that from him and sniff the connection for resistance values etc.
Hey...I'll leave that level of wizardry to you! Good to know there is a possible answer.

High Speed Charging
Dear All:
I do alternate energy research and we deal with Li battery packs all the time and have seen fires from improper charging. It is okay to advise rom and other software mods but when dealing with electricity it is possibly life threatening. We do not want to read in the next days post about a member dying in his sleep due to a fire. Please use utmost care when you post soldering and wireshorting hacks. We do not know the technical level of the person on the other end.
Second-most, the quality of third party chargers is very shoddy and they do not follow IEC or UL codes which adds another danger factor.
For example I bought a Chinese made Lamptron inverter for my cathode lights and the input wiring was wrong could have fried my gaming rig if I didn't check.
I understand your convern but 1800mA is the charge rate of the wall (ac) charger. That's what we're trying to achieve with a car charger. If you buy crap you're asking for problems. Most car chargers can output 2 full amps @5v but are setup to only charge at 500mA. USB charging of smart devices utilizes the data+ and data- lines as charge mode indicators. Small changes in resistance (therefore voltage) changes how the phone will pull amperage. I think everyone knows the danger of overheating lithium-ion batteries. We're not trying to do anything more than what the wall chargers already do. Check out xda a bit more and you'll see lots of posts about this very subject for different phones. Like this one. Or check out Ladyada's ipod charging research for some other good info. FYI, a good source of CCFL inverter parts is in old broken lcd tvs. Cheap, easy and reliable.
Now that that's out of the way, i set up a breadboard today so i can check some things out but had no time to test so hopefully tomorrow i can give some insight as to what the revo wants data line wise so it goes into "type 2" 1800mA charge mode. Will post with what i find and maybe some pics.
Alright. I just dug in for an hour and found out some things. My wall charger supplies 3.68vdc on both the data+ and data- lines. While using this charger the phone (using /pro/kmsg) goes into "type=2" charging mode with 1800mA. So. I hooked up my car charger. I noticed 2.1vdc on only one data line. So i made a quick resistive divider up to bring both data lines up to 3.68. BAM...didn't work. I also tried shorting the two data lines together while at 3.68v....nope. Then i threw a potentiometer in between the two data lines and tried a few values up to 200ohms....nope. I then pulled all connections to the car chargers data lines and supplied a fresh 3.68v to the output cable...nope. Last thing i did was just use my power supply to supply the 5v and gnd without the car charger in the loop....still couldn't get a type 2 charge. I'm losing my mind here. I think i missed something stupid or am over thinking this. I might start from scratch later but first, i need a few cigarettes. I'm hoping someone can chime in with a simple fix and call me stupid
I found another charger i had bought from radio shack a while ago. It's a PointMobl charger. Plugged it in and got an 1800mA type=2 charge. Sweet. Now i'm gonna dig into it and see why it works....plus i'm ditching the damn spiral cord cuz they piss me off.
I'm using the wall charger from a Moto Razr, and it puts the Revo into fast charge. I found the pinouts here: http://pinouts.ru/all/razrv3_charger_pinout.shtml
Any new insight from that?

Some phones are like that. Common usb is 4 wire, micro usb adds another pin. That pin needs to get a 200ohm resistor jumped to the shorted d+/- lines. The thing is, the wall charger only has 4 pins like every other usb. Unless the cable itself has the extra pin connected to the data lines through a resistor, it still doesn't explain the difference. I haven't taken this other charger apart yet, actually, i don't think i can without destroying it as it looks to be sonic-welded at the seams. What happened to the old screw-ended cig lighter adapters??

Wall charger: 100 to 120 AC converted to low voltage dc
Car: 12v DC no conversion, probably resistance regulated.
Stating the obvious the wall charger is a complete different beast from the low voltage computer/car charger. With out a 12v dc to ac converter I don't think you will ever get a car to charge like a wall charger.
Your radio shack device probably uses some type of capacitor device to ramp up the juice then runs it through some sort of regulator which simulates the AC style charge.
Or at least if I was designing one that is how I would do it.

My car charges like a wall charger. It's not about inverting alternating to direct. It's about getting the phone to pull the amperage. Regardless of what the max current is, the phone has modes of charging. It will pull what it's directed to pull depending on the charge mode it's put into by either d- and d+ voltages and/or resistance across certain conductors. Most car chargers can produce a full 2 amps, that's not saying they are actually doing that though. It all depends on what the phone is taking, not what the charger is giving. You're looking at this the wrong way. 90% of chargers are capable of the output (dc car chargers), it's the phone that desides what to pull according to the chargers instruction (data lines and/or 5th micro pin). The charger's maximum output is equal to the fuseable value it contains. So. Yes, my car charger charges the same as my wall charger. By the way, capacitors by themselves store energy, they don't "ramp" anything. The only caps in my car charger are for smoothing as far as i can see. It's all about resistance, not capacitance. A wall charger is just a car charger with an inverter before it in the sequence. In fact, you could open a wall charger up and split the two circuits, apply 12v to the dc half's input traces and get the same effect....without the ac components even in the same room.

Buy inverter.
plug in AV charger.
Enjoy AC charging in your car.

I went to Radio Shack today and got one of these. It shows up just like the ac charger does. I will be able to use it in my car dock for navigation and not have to worry about the running the battery down. At least that is what I am hoping for.
I bought what i thought were a couple higher quality universal chargers. They charge my razr fast but won't charge my nexus 7 at all. I have one of the chargers pulled apart but before I do any soldering I want to make sure -- if I cross the 2 data points will it work?
Well I couldn't wait 10 minutes so I tried. Answer: no. Wtf?
Can anyone tell me how to hack these chargers to make them work? Is there a resistor I need to remove?
Isn't it more likely to be a software thing?
With my samsung Tab 7.7 i couldn't charge it using my ipad charger until a Dev modded the software on the tablet.
are they 2Amp chargers? most universal chargers are only 1Amp
Well whatever the problem is, I want to charge my tablet in more than one place, I want to charge it faster than the 16 hours generic chargers are taking, and I don't want to pay $30 for OEM chargers.
If your tablet is taking 16 hours to fully charge, return it. I can drain mine after heavy use of the day and its still fully charged in under 6 hours.
Sent from my Nexus 7 using xda app-developers app
@soldeus: There's nothing wrong with my tablet. The OEM charger works fine and some of my generic chargers work, they just don't have the current. (See below)
@vivan: They are 1A chargers, but they should still work. They don't charge at all. The 500ma Blackberry charger I'm using here at work will charge it in about 8 hours.
Ironically the move to almost-universal micro usb chargers has made the market for them even worse. Now, instead of having to buy a new charger every time you buy a new phone, you have to buy a dozen different chargers till you find one that actually works. Like I said, I didn't try to cheap out. I got a high quality charger.

The OEM charger is 2A for a reason. Because the tablet uses more power, it needs more current to charge at a fast pace.
Your generic 1A chargers are probably just enough to keep the tablet powered on, without draining (or charging) the battery.
If you can find a 2A universal charger, it should work just like the OEM one.

No, my 1A chargers are doing NOTHING at all. I plug it in and the charging icon doesn't come on. Reviews have tested these chargers at about 950ma and as I said, my 500ma Blackberry charger isn't too bad.. It's not lack of power, it's something else.
My guess is it has whatever resistor it needs to make it an "ipad" charger. And the vast majority of 2A chargers will, too.
So.. back to my original question: what do I need to do to make this charger charge my tablet? I KNOW it's possible. I just need to find the guy who can tell me how.
I also need a charger for my car, my usb power adapter in the car does not work, need to know what car charger will work as this tablet is supposed to be my car stereo replacement, sucks having to bring your stereo in to charge it and hope it lasts till you get done work
I bought the Scosche dual 10 Watt car charger, isn't here yet though. It does say it wont charge the Samsung tablets, maybe due to the proprietary cord because apparently there is a cord that works with them. It's not a specific ipad charger and does say it works with Android devices and tablets.
On a side note, what's the best way to determine what your N7 is actually charging at?
Both of my generic chargers won't work either, a 2.1A generic iPad charger, and a 1A standard USB charger. Considering it WILL charge off a 500ma USB port, it's not a current/amperage issue, it's a software/proprietary hardware issue.

the cost isn't so much the issue, its the actually working part. do they have one with an angled micro usb so i can mount the tablet in the car properly or preferably a usb adapter one where i can use my own cord
For $30 you could order a handful of different ones on ebay or monoprice and find something that works. But I want a dual charger.

I won't say 100% but I would bet the probability is very high. For the 1A charging they all seemed to play the same game with the voltage on the data lines. Not sure you'll get 2A but you'll at least get 1A.
