Get the charger at the link below
http://www.amazon.com/Motorola-Vehi...Q9CA/ref=sr_1_1?ie=UTF8&qid=1334801727&sr=8-1
I got this to replace a cheapo one i had when i had my Droid X. With the old charger, I couldnt keep the screen on and use GPS and listen to music at the same time without the battery losing power. Basically the old charger acted like a battery extender lol.
This new charger charged my phone at least 3-4x faster...even while doing all the things listed above...WELL worth it

I have that exact same car charger. Just make sure that you get it from a reputable dealer... I got mine from one of the parties for a few bucks cheaper and they sent me counterfeits. I had to contact Amazon where Amazon gave me my money back and also sent out two OEM from an Amazon warehouse with free expedited shipping!

Quite a few of the cheaper car chargers simply do not have a point soldered on their boards, causing the phone to think it's charging from a 500mA USB port (like you'd find on a computer) and not go above that even if the charger does 1A/port.
I know even the belkin one has a forum topic somewhere regarding modifying it so that it'll always get detected as an AC power. I believe custom ROM's and kernels has a Fast Charge feature that can fix this too (ie force the device to detect the power as AC), I think.

I use the Motorola charger as well, and it works just fine... I had two lying around, one came with my Milestone and the other came with my Milestone Car Dock that I've bought separately...

Interesting, this is the model I had and I ALWAYS felt like my battery was draining while using the GPS+Music combo. Not a lot, a few percent over a couple hours, but it's not charging it or atleast keeping its current charge. I want the official Sammy card dock. SOMEONE JUST TAKE MY MONEY.

I believe you will be disappointed...
First, this Motorola charger is good up to 2A, while the original Galaxy Nexus Wall Charger is good up to 1A, and Galaxy Nexus recognizes it as AC Charging, meaning that phone is draining as much current to charge as it can...
Second, I do not believe that those pogo pins are good to move 1A, and I could bet the farm (if I had one ) that it won't go over 1A for sure, so, I do not believe that the official car dock will allow more current than what this Motorola charger is already providing...
But, anyway, I doubt that charger is the one to blame, and I will tell you why... Battery is rated 6.8W/h and it usually allows up to 4 hours of screen on time... So, quick math, phone in use, screen on, is draining 1,7W/h and USB charging (500mA x 5V) gives you 2,5W/h, AC charging gives you 5W/h....
Lets say that you get up to 3 hours screen time with GPS on... It still is 2,27W/h... Below 2,5W/h USB charging limit...
So what is going on? Probably battery is too hot charging and being discharged at the same time (and probably the phone is not able to use the battery like a no-break and get its power from USB, so, phone is getting juice from battery and battery from charger) and phone will stop charging to avoid battery damage/explosion due to high temperatures, and also, battery efficiency is lower when battery is hot (it will drain faster)...
My guess is that if phone is still draining with a charger, in this case, check if it is too hot, and if it is, try to move it so it is cooled by car A/C / vent... At least, with milestone, it helps a lot, since I still own my Milestone and its gps is leaps and bounds better than Galaxy Nexus GPS, I've never really used Galaxy Nexus to navigate (yes, my Milestone turned into a dedicated Google Maps GPS )

its very easy to mod any usb charger to turn it into a AC charger. what you need to do is connect the two data pins.

just connect pins 2 and 3 by solder, i've done this on a few car chargers and it works great always shows AC. i didnt modify the usb wire itself but opened up the charger and connect the solder points connected to the data lines, not sure if you can just mod the usb wire. i have 600mah car charger that i did this to, before it wasnt enough to charge the phone with google maps running now it can charge it very slowly.

Just a update,
i purchased the motorola charger and been working great for nearly a month till this couples of days.
the only way that charge is by holding and pushing up the micro port wile inserted in the phone.
i noticed that the charger micro plug does have clips on only one side ,the other side is flat.
does that mean is not a original charger???
thanx

I'm currently using this cables
http://ca.startech.com/Cables/USB-2...USB-Cable-A-to-Left-Angle-Micro-B~UUSBHAUB3LA
with this charger:
http://www.kensington.com/kensington/us/us/p/1411/K39224US/powerbolt™-micro-car-charger.aspx
No issues. the USB cable is very thine, so hides well on the dashboard.

http://www.amazon.com/HTC-T-Mobile-...KTHO/ref=sr_1_3?ie=UTF8&qid=1337307263&sr=8-3
generally can be had for about 3 bucks shipped. works fantastic - the phone reports as being plugged in and charges accordingly.

Monoprice 2800mAh portable battery box

I just got a portable battery box (2800mAh) for $14 from monoprice. (LINK)
Nicely built, relatively small, and about to test whether it will give me 1.5 full charges as mAh would suggest (2800mAh / 1800mAh on HOX = around 1.5 charges).
Box itself doesn't come with any charger, but is able to be charged by any charger with Micro or Mini USB connector (yep, it has 2 inputs).
Output is a male MicroUSB connector that fits HOX nicely (duh!).
Output: DC5.0V 800mAh

I'd imagine if you want to use the phone while charging from it, you can connect them with a female-male MicroUSB connector.
The charger has a button that shows the charge level of the box with 25% increments (4 lights).
Has another light for "FULL".
As soon as I connected the box to HOX, phone immediately showed that it's being charged, as if from the regular charger. Not sure what the current is, but it may come across as slow charge (USB port charge) as opposed to AC charger.
So far I tested the charge over 10 minute deep sleep period, and I got this:
With the box, in average HOX charged for 2% every 10 minutes.
That would suggest that it would take this box 8.3 hours to charge HOX fully, which isn't bad at all, considering you're free to use it while it's charging.
Over next day or so I'll try to completely discharge the HOX and charge it overnight from the box. I'll see just how much this box can spit out.
---------------------------------
EDIT/REPORT:
I discharged my phone to 5% yesterday, disabled wifi and BT, and connected it to batt pack to charge overnight.
It turns out that this batt back is crap.
Overnight, when phone was in deep sleep with wifi/BT off, a full battle pack charged my HOX only by 55% (I charged the batt pack before using it). Even considering some small drainage during charge, I'd say this pack actually acts if it had just over 1000mAh or so, nothing close to 2800.
Oh well, gonna return it and keep looking.

shouldn't this be in the accessories forum?

Hate the ones that plug right into the phone like that. Pretty much makes the phone a huge pain to use. I would rather spend the extra money and pick something like this up

That's a good option too, although I actually like that monoprice's sticks right into the phone, so you don't have to carry a cable with u.
Also, it seems smaller and cheaper.

I know of certain defense organisations that allow the fixed connectors but not those with detachable cables. Disallowing the cables reduces the risk of the cables being used for data transfer.

huh?

It's a security standpoint from Defence services (IE: Australian Army, etc) who wish to minimise security leaks. A data cable can be used to link up other devices, not just the charger.

Okay, and I guess if I were flying in outer space, my suit was venting air, and the only thing that would save me is connecting a batt pack to a phone - in that situation a cable could freeze solid to a connector on the batt pack, making batt pack unusable, and thus killing me.

WRONG!
That's when Iron Man comes flying to the rescue thus saving your life and getting an autograph that you could sell on eBay for some money and covering your costs of the HTC One X.

OK well, turns out that this batt back is crap.

External Power Backup 3000-3200mAh

Hi everyone.
Be care full all things of this kind of battery is just publicity nothing real.
Here is how it's look

Inside is just a regulator for charg internal battery and a power up convertor to get 5V
The main battery who run this external battery is just a big flat 2800 mAh 3,7V battery more exact his code is YY 426390P 3.7V 2800mAh 12YE005.
Price tell you how much is plastics, how much is true and how much is publicity.
Here is the pics with image from what is inside.
Power Board covertor up/down from 5 to 4.2V max (that much can take Li Ion battery) when charge extender battery and up convertor from 3.7-4.2 to 5v to power your phone.
All parst who make the extender
The back cover of extender
The EXTENDER BATTERY 2800mAh not 3200mAh and never will get 2800mAh as he convert his power to 5V wher will lose some power on convertor (the button for on/off get hot when is used to power your phone)
Make a litle ajustment for hole of back camera and flash because when you shut in low light and have flash on or auto the white around flash will get back on your camera and picture will get unclear and with to much shadow. I will got a permanent marker black and make the hole black around camera and flash. In this way i can take a pic w/o get some noise from white.
Here is things who get broken easy w/o meaning i wish to do that i never know when i did that but i did it
As advice if you want a battery extender dont get this kind better buy an another 2500mAh and you get more power than from this.
Or use and inside replacement battery than external power battery except the price is very cheap.
Remember this batterys have some power to lose when get charge your phone because is a convertor who get hot (more or less ) but that means he lose that power.
Using my old 3.7V 3000mAh battery from Galaxy I9000 give me more power than this Extender and was only 10$ instead of 19$ who was this.
For around 10$ will worth and not you buy it for extend your time to play with phone but dont expect to much.
Hope some will get this value at least i will feel good because not all got cheat by numbers

Bought one of this (black) on ebay for £14.99, and I can tell you that it can not charge the phone battery over 85%. Phone gets excessively hot whilst getting charge. Also, IT TAKES FOREVER TO CHARGE UP THIS THING. Standard battery charges up in about 2.5 hours but it takes more than 8hours to this power pack.
NOT RECOMMENDED.

Sigh, and I wanted to get one for my Note. I guess it has some issues with build quality. :crying:
Anyways, thanks for the heads up.

I nearly want to bug exactly this type of power bank. Now, change my mind tp buy cheap extended 5000mah instead.

Get 2 this even they dont have real 5000mAh will get more than 1 as 2600-3000 and is a pair of 2 so you will have 3 battery for a very low price and 2 of them it will keep you all day long using alot.
Here is the link of what i order.

Thanks for your recommend link. So, cheap 5000 isnt really 5000. It will be less than that. So i need to prepare 2x 5000mah for me to last a day long. I can order from ebay. Maybe will search other thread to buy it.

Hoping for a reply on this old topic..
Sorry for bringing back an old post, but I have a question about this. I actually bought one of these long before I ever read this post, and to be honest up until it completely stopped being able to charge my internal battery, I never had one problem with this case, and actually really liked it. All that came to a sad halt when one day, it just stopped being recognized by my Galaxy Note when plugged into it. Which mind you really made no sense to me because if I plugged the little Mirco USB tail to another device that could be charged by the same battery and had a Micro USB female to accept it, it was picked up and had no problems charging it, as well, my Note could be charged by any other Micro USB charger, so why all of a sudden it stopped being able to be charged by this case/battery is beyond me since both work fine unless plugged together. I contacted the place where I purchased it and they did send me out another one free of charge and told me to keep the one that wasn't working anymore.
When I found this post, I decided to open the the broken one, and googled the number on the battery "426390P" which was the only reason I found this post. This post actually surprised me because up until this one stopped working, it was working perfectly fine on my SGH-i717. I mean it charged the battery everytime to 100%, sometimes it would charge my battery about 1.5 times before I would have to recharge it. I thought it was the best case I have ever used quite honestly.
So now the real reason for replying to this post. Do you guys think that if I could find a 3.7V, higher mAh battery (or even make my own) that would fit in the case, it would work with the upconverter board that is already inside? I am no electronics expert, so I don't know the functions of all the pieces on the board, but I figured if I could find or make a new higher mAh battery that would fit inside, not only would it beef up the longevity of my battery life on my device, but it would allow me to keep using a case that I actually like and love the way it fits with my device and since I have the black case, I do not have the glare issue with the camera nor any shadowing issues.
I am curious as to what you guys think..
Thanks in advance!

Phone won't turn on :(

I've been experiencing some problems with charging and I read in out of the threads that I could use a bit of electrical contact cleaner and it would work. And now my screen protector is ruined and my phone won't fully turn on. It boots up, vibrates then it turns off. What do I do I'm freaking out right now. I'm going to put it rice to see if that works at all Anybody know what I should do I'm really scared right now.

Exactly what did you use? Link to the product.

Yea a little more detail on what you used would be very helpful.

Jesus I feel like the biggest idiot of life. You guy don't realize how F*cking stupid I am. After being in a complete rush I used the wrong type of cleaner. So After I soaked it in rice and took it out I actually used a proper Electrical Contact cleaner and and now everything is fine. But I am now certain that the cable is done because it wasn't charging or showing that it was plugged in so I used my friend's Blackberry cable and everything is fine. I'm so relieved right now.

Lol glad to hear that its fixed.... we all make mistakes

Thanks, the only problem I'm still back to is that it won't charge, which is what was happening before. I am not sure whether it is the charger itself or the micro-usb charging port (Which I could replace). Phone thinks it's charging with the lightning bolt in the top right, but it won't charge...if I go to battery in the settings it says discharging but in the charts it that it was charging all this time.

Tbh I don't know but this is a educated guess.... seeing that it shows that its charging on the phone means that its receiving the charge. A good test would be to take out the battery and plug your phone into the charger. If it works that means that the port is OK and you'll need a new battery. If not then its the port. Hope this helps.

What do you mean by if it works, as in if the phone boots up and works normally when plugged in?

When you take out the battery and plug it in to the charger it should work normally as its getting power from the plug.

Meh whatever, I smelled and it was just the smell of the wrong cleaner I used, luckily it was just on the plastic parts so I'm safe, I disassembled the rest and found the charging port. I'm ordering a new one for $10 shipped from NJ and not from HK so I should get it soon. Thanks for your help btw. I really appreciate it. :good:

Good luck bud

Update: I just replaced charging port literally just now and it still won't charge. It still says "Charging" but it's not charging. In the Settings it says discharging.
Could it be the battery? I'm thinking of buying a new one and seeing if that works.

Updated Update: The 6% that had remained on my battery before I took my phone apart to repair it is now gone leaving the battery with 0% charge. But, I believe I may have found the problem! If the phone is unplugged from my charger and I try to turn it on it won't turn on at all. But if I plug it into my charger it will boot up past vibrate to the Nexus logo (The X) and then it dies out. I think that the problem is in the charger that has a input voltage drop so it's not charging enough to keep it going. I'm going to use my friend's Samsung Charger (From his Galaxy S II) to see if that will solve the problem.

Samsung Note 10.1 2014 Edition (P-601) wont accept new batterys

Hey there,
greetings from germany. Pretty sure this belongs to "Questions and Answers", if not - please hit me and move it.
I am confronted with a, in my opinion, strange problem regarding my P-601 Samsung Note 10.10 2014 Edition.
I will try to provide every action I took and what I figured out so far that noone that wants to help will need his crystal ball. But the first actions are about a year ago, so forgive me if I cant remember exactly.
Device: Samsung Tablet Note 10.1 2014 Edition (P-601)
Problem: Charging slow AF but lives, can be turned on, can be loaded via USB. (But more power is drained while using than can be delivered by charging = dies sooner or later while beeing used)
OS: LineAge OS
First I thought, EASY - get a new battery, done. Wrong.
I ordered a new battery, a (2) "vhbw" battery for "T8220E" - same mentioned on the original Samsung battery.
This is a year ago, In my belief I did get the tablet to run, and charge- but had the same problems regarding the charging speed. Slow AF - but I am not sure! Life happend, things came inbetween so I did put everything aside. Now I want to use it in my home gym, so thats why I came up here.
My next suggestion was that the charge electronic maybe the problem, so I ordered a new one, built it in. Didnt change anything. The (1) Original battery, is still charging slow af.
The new battery, doesnt do anything! If the (2) "vhbw" battery is built in, I am not able to turn the tablet on OR charge it. Its just a brick with this battery.
So what did I do? I ordered a new battery, from a well known german company trading parts like this, a (3) "original samsung battery". Guess what, the tablet does nothing.
So i thought, maybe your new charging electronic is the problem. So I put the (1) Original Tablet battery in again, and well - it runs, can be turned on and can be charged (slow af).
So the charging electronic is fine. Display is also fine.
I did confirm this several times by changing the batterys in and out, the new batterys (2) and (3) are "dead", the (1) original battery runs.
Right now I am stuck. It seems that my Tablet is blocking any battery besides his original one.
Note: I cant access Recovery Mode with battery (2) and (3). Its really dead. They where also charged atleast an half an hour, just in case they were delivered "really dead at 0%", which would be new to me because most devices or batterys come with atleast 25% battery status.
Note2: Yes I did use a ****load of power adapter and cables all in combination, same result.
Any help is really appreciated! Thanks in advance.

Hello, I came here looking for recommendations for a new battery for my SM-P600. Could you tell me where you ordered your OEM one from?
As far as your problem, do you have a multi-meter? There are very cheap basic ones if you don't. Anyway, you can test the seemingly dead batteries with it to determine if they are in fact dead, or something else is going on.
Secondly, do you happen to have a hobby charger? With these, you can charge pretty much any battery L-ion or other. You can also do a drain test with most of these to determine the capacity of a battery. That is all I can really think of thus far. Determine if the batteries are dead. Oh one more thing you could do with the multi-meter is test the current being applied to the battery. I believe there are some free apps in the Google Play Store that can also tell you the electrical current going into the battery. Perhaps by doing this you can determine if the problem is something in the tablet itself. If I think of anything else, I will let you know.
Thanks

Hey,
thanks for the feedback.
You mean battery (3)? I ordered battery (3) from ng-mobile.de
Funny that you say that with the "dead battery", because I just had the same thought 10 Minutes ago. Those batterys were manufactured years ago I guess and were just sitting cozy in their boxes, I guess they are deep discharged. (hope this vocab is correct).
I have pretty much everything that is measured "useless" in a normal household, but sadly no multi-meter (no more). If those batterys are deeply discharged, it should be possible to be reanimated with very low charging power. The lowest I should have is a USB 2.0 Port on my pc (which were it is connected right now) or a oldschool dumb power bank without any intelligence).
I will keep this updated.

It worked. About an hour connected to a USB 2.0 port of my computer, and it just popped back into live. Thanks for sharing your thoughts with me!

There have been reports of the plugs of replacement batteries for these tablets not fitting properly.
Also bad solder joints at the battery connector.
And a certain behaviour i oberved myself, requiring certain custom roms or chargers in case of my P605:
In soft-off state tablet will charge at 0,5A instead of 2A max
and
When powered on it will charge at full power until the screen switches off and it enters standby. Then no charge at all.
