I apologize if this is a dumb question, but I'm not exactly an electrical engineer. I was looking at buying one of these for my room: http://www.thinkgeek.com/gadgets/travelpower/e81a/ and it says it outputs at 2 amps. i notice the stock Samsung charger is 1 amp. Will I be doing any harm to my phone by using the wall outlet vs. my stock charger? Or will it detect it as a USB charger, charging it at a slower rate?
Ya it'll be fine, it says UP TO 2.1amps.
Also it says it charges all mobile phones that accept USB power.
yes it will work. I have a few of these installed in my house. Your device will only pull the amount of amps that it needs. The voltage is what you have to look out for...
it will work, but it is not up to the 2011 nec code as it doesn't have tamper resistant shutters, I would recommend this instead.
http://www.amazon.com/Cooper-Wiring-Devices-TR7740W-K-Combination/dp/B007NC5GI4
It works the same, is up to the latest electrical code, is cheaper and will work with a standard wallplate.
Thanks for the input everyone, I think i'm gonna spring for one (may not be the Thinkgeek one though, as the one cade80 posted and a few other's I've found are cheaper) at some point, just to cut some clutter from my bedroom a bit.

Although you lose 1 standard plug, the big plus is being able to use normal faceplates with it.

Be aware, this Cooper one is only 0.7A ... it won't charge an iPad 3 and is slower to charge then the OEM Samsung charger.

Good eye on that, depending on your needs this may outweigh the being up to current electrical codes.
most third party charger will not charge you samsung smartphone at full power.
to charge at full power you must shortcut middle pins.
"will not charge" - not correct, your phone reduce it
So I went ahead and decided to not spring for the ThinkGeek Charger, and instead bought one of these: http://www.lowes.com/pd_369050-6337...&pl=1¤tURL=/pl__0__s?Ntt=usb&facetInfo= and just put it in a standard plug to test it to make sure it worked. Well I plugged it in and the first thing I noticed was the GNex was taking a while to recognize the plug. Finally it started Charging (USB Though) which was OK with me. Well last night I plugged it in via my Samsung Charger to a standard power strip because I hadn't gotten around to installing the RCA plate yet. Well I woke up this morning and it was on like 50% power and wasn't charging. So I was like WTF. So I brought it into work with me this morning, and now when I plug the stock Samsung charger with the stock samsung cable into the wall, no charge. I tried plugging it in to my computer, and it eventually makes connection with the computer (it's not instant like It used to be) and Android File Transfer starts, but says it can't connect to the phone. Then it charges for a few minutes, up about 1%, then stops charging. So my question is, when I plugged in my phone to the RCA charger last night, did it fry my phone? Or is my charge cable maybe bad now? I haven't tried another cable yet (everyone at work is an iPhone user and doesn't have a Micro-USB cable lying around) but I'm going to try that and hope it works. If it's not the cable, is it possible that the phone itself got damaged? If so, how could I go about removing root and wiping it to take it into the VZW store for replacement without USB to the computer?
Another new development. I plugged it into a Windows Box (I was using a Mac) and when I plug it in, it says "This Device can perform faster" and talks about plugging it into a USB 2.0 port. I'm using a 2009 Macbook Pro, it has USB 2.0. It won't mount the disk either. So i'm really beginning to wonder if the USB cable is fried.
Turns out it was a bad USB cable. Went to Best Buy and bought a generic cable and it now charges and hooks up to the computer just fine. My ADB doesn't seem to be working though for some reason, on Mac or PC...
Ok, everything is working now. ADB wasn't working because of a conflict with EasyTether on my Mac. Thanks everyone for the suggestions but I've decided to just stick with what I have now (power strip) and not deal with it.

May I recommend you return the Best Buy cable and go to monoprice.com?
I bought five cables from them that are 6 foot long. They work terrific and are higher quality looking than what you get from Best Buy.
Today I picked up and installed two combo 120v/USB wall outlets so I can get rid of all the wall warts I currently have. The USB ports charge everything (tablet, HTC phone, Bluetooth) but the two galaxy S4's I have. Has anyone used one of the outlets before? Any ideas on why they will not charge the S4's?
The Specs for the USB side of the outlet is.
Switching Frequency Typical 140 kHz
Output Voltage Nominal 5V (+/- 10%)
Protection Current Limiting and Thermal Shutdown Protection
Output Current Constant Current Maximum 2.1A
The outlet is a Commercial Spec Grade Combination USB Charger made by Cooper Industries
Part number is TR7745 if anyone wants to look it up for any reason.
Thank you in advance for your help.
change usb cables
Try changing to a different USB cable. It's weird how often this is the problem.
What does it do when you plug it in? Does it do anything at all? Does it even act like it's connected? Does it TRY and charge but just can't keep up? I have ones by Leviton that work fine with my S4 and my fiancees iPhone/iPad.
EDIT: I just noticed if you look at the reviews on Amazon HERE it seems multiple people have had problems with the S4 and this model. One thing I noticed with most that I looked at before buying mine was that the listed current was shared between the ports, whereas the Leviton version has one port that's 2.1 amps and one that's 1 amp independent of each other. This one might be 2.1 amps shared, so anything else plugged in might not work out.

I'm having the same problem. It's listed as "dual 2.1A". The first second I plug it in it flashes the charging indicator, then it goes off. No charging happening whatsoever.

Did you ever have any luck with the S4 problem? Does it make a difference which side you plug the USB cable into?

Try using a different usb cable from phone to charger,
be sure both ends have a snug fit and it should work.
I have one which is similar to yours.
Since it puts out 2.1ma just like the stock S4 wall charger
it should charge just as fast.
Good luck!

Unfortunately no. I didn't mention before that I'm an EE, however, none of the troubleshooting steps I could think of had any effect. :crying:
Can use A Cooper USB Electric Outlet with S3 and S4
I saw this thread while trying to solve this very issue. I have the Cooper USB outlet and installed it thinking it would charge my phone and my wifes. It would charge her S3, but not my S3. She has the LTE version (SGH-I747) and I have the HSPA version (GT-I9300). Well I thought it would not charge my S3. After playing with it for a few minutes, I could get the charge light on the outlet to blink. No charging was happening as the charge light on the outlet would just blink and then stay off. On my wifes S3 I could plug it in it would start charging instantly.
After playing with my S3 and the cord (The same cord used for my wifes S3 as I had already tried numerous cords) I found I could slowly insert the micro usb end into my S3 and it would start charging. It was tricky, but after 30 minutes of wasted time, I got it to charge. I would have to ever so slowly plug it in, either at a sideways angle or at a slightly elevated angle. This was regardless of the usb cord used.
However my S3 died and I got an S4. Naturally my S4 would not charge just by plugging it in, but I tried the "slow insert" method, on both the micro USB side and the outlet side and both worked.
I am thinking there is some kind of tolerance issue surrounding the electrical connections. Sliding the USB connector in slowly at the outlet side, I beleive, would ground the connection first and then allow for charging, but this is where my knowledge of electricity starts to bad. That said it is possible to use the charge, but it is not plug and play.
I just picked up a couple of these for the kitchen to alleviate the eyesore of the wall warts and I can also confirm it charges everything I have thrown at it except my S4 (jfltezvw) =( I quickly found this post after googling it. I am currently doing some work on the phone now but I will attempt the super technical "plug it in slowly" later and see if it works =)
Has anyone had any luck with other brands? I find this REALLY odd.
just installed this same outlet, and sure enough it charges everything except the S4..."slow insert" doesn't seem to work...does anybody know of any other solutions besides not using it?
wall charger option
I also have one of these outlet/usb from cooper that will not work with my s4.
Has anyone tried to use a DUAL POWER micro USB cord (like the ones that comes with the portable hard drives) to see if that would do the trick?
unfortunately, I do not have one of these cables, or I would try it myself.
Here's what I am thinking is happening...
The S4 is equipped with a smart charger that can trickle charge after a complete charge cycle.
When first connected, the s4 starts a trickle charge while it tests the battery for the charge cycle.
The cooper is equipped with a current limiter that shares power between the two outlets.
The cooper unit sees the trickle charge, and switches to a lower current setting for the slot with the s4 plugged in. reserving current for the empty outlet.
The s4 then tries to engage a fast charge, but cant due to the lack of current, and shuts down the charge circuit.
If a dual usb cord to micro usb cable was used, both outlets would be tied to the s4, and full power would be available to the s4 at all times.
Of course, without a cable myself, this is almost all conjecture on my part, and I could be just blowing smoke up my own arse, huh?
LoVoltage
EDIT: Of course, remember that the cable you use has to have the D+ jumper to signify the 2.1 amp availability. If you don't, the cable won't work. (Most dual port usb cables have this jumper already. so does the OEM samsung cable)
Just installed one of these tonight. Specifically the Cooper TR7745/TR8245 15A/125V
I can charge my Note 2 (SGH-I317), Nexus 7 wifi, but not an Samsung Galaxy S4 (SGH-I337). Kinda weird.
Since most third party chargers don't work anymore with the KitKat update, did anyone try an external battery?
All chargers works, just depends on cable and not chargers or kitkat. You get faster(slwoer charging depends on charger and quality of the cable.
For u question, I used Trent 11000 mah external battery pack, 5V 1Amp and with 3rd part usb cable, that are only for charging, without "data pins". It charging at 500 mah when screen is on, screen off at 930-980 mah and working as normal.
I dont know where u get that kitkat have anything to do with 3rd part chargers doesnt works.

Well my third party chargers stop charging when the screen turns off. Even if I use the USB cable that came with the Note. However, old chargers of HTC or Motorola phones do work with any USB cable. And I have read this from several other users as well.
I'm on stock 4.4.2 with stock recovery. What recovery/kernel/ROM do you use?
I only use third party chargers and cables and have never had a problem.

The problem is Samsungs OEMs usb cable. I found it kinda weird, probably Samsungs have some kinda "handshake" with data pins and I got few of them from old Note 1/2/2014 and somehow it doesnt charge mine old Note 2 anylonger.
I got 4 of Samsunsg OEMs USB cables that comes along with Note 1/2/2014/EED100 (Desktop chagerstand) and I dont know anylonger which one is for each device. If I use wrong Samsungs usb cable, it charge mine Note 2 very slow, battery also drops while charging and I got to pick right usb cable for it to charge normal.
Now I just use this usb cable to charge mine Note 2014, too lazy to swap cable until find correct one and it works fine with any charger.

I tried using the Note charger with different USB cables and it works. Using third party chargers with Note cable does not work, but using HTC/Motorola chargers with any cable does. So I think the problem is with the charger, not the cable. Are you sure you used the Note charger with diferent cables and it didn't work?
Using a 1.0A charger charges the device obviuosly slower but the third party chargers (also 1.0A) stop when the screen is off or the device is powered down.

SM-P600
Might be it's a bug in the 605 ROM/kernel. Or maybe related to the snapdragon 800 chip. Maybe Samsung screwed up some drivers, intentionally or not.
If anyone is having charge issues, change your cables. There's nothing special about a "Samsung" cable, but there's a lot of cheap cables out there that have enough voltage drop on them that they won't allow adequate charging. Also, make sure your charger is doing "AC" charging, not "USB" charging- the Note won't draw more than 500mA from USB charging and you may either experience slow charging or none at all if you're using it.
I'm running a P607T (US T-Mobile) model with the German P605 ROM (which should rule out "locale" differences), and my Note charges from any third-party charger I have and/or my Gorilla Gadgets charger battery just fine, whether screen is on or off.
Like I said before, my third party charger stops charging when the screen turns off, even if I use the cable that came with the Note. In settings under battery it says "charging - AC" but still.
It may very well be that these chargers are too "cheap".
The Samsung cable misses one of the two ground connectors. This method was used for devices with mini (!) usb to put them either in power or data transfer mode, depending on the cable used.
However, the Note don't care, I charge it with a 5pin-cable.
The charger should be fully Android - and Apple compatible, as the Note most likely checks for Ipad-compatible signals on the data lines for 2A support.
The USB Port of the P600 is really weird.....I`m searching a long time for a solution to use USB and charging at the same time, and I`m testing a lot of dockingg Stations for this.....thats really strange.....the Multimedia Dock, made for the Note 2, works with the Note 3, without Problems, alll Ports are working....but P600 doesnt accept it as any docking stations, it do absolutely NOTHING, if you put it in.....with the new desktop dock (without usb) both devices will accept it as an "Docking Station"...other Adapters, like Hama, with SD Card Reader, USB and micro USB, will accept as an USB connector, all works, but not charging......but now, the LAN to USB Adapter from Samsung for the PRO Tab Series, wich have 2 x USB, LAN and Charging Inputs, works fine, except the LAN Port......think, there no drivers there at P600.....The USB Port is not same pinned as the Note 3, and also not same as the Note 10.1 and other older Tabs.......maybe it`s same pinned as the PRO Series.....but not sure......
Gesendet von meinem SM-P600 mit Tapatalk
My USB cable charger cord that came with my P-600 is starting to loosen up. You know, when you have to adjust out so it's in the slot just right in order for it to charge. I know that you can't use just any AC adapter combined with just any USB cord to get the power needed to charge a tablet fast and efficiently. Are there any recommendations out there for a new AC adapter and/or USB cord that has been proven to work well with this tablet? (Besides buying a replacement from Samsung.)
Thanks.

Right. I think most smartphone chargers won't even be able to charge a tablet at all because a tablet, any tablet, needs more power (volts) to charge it effectively. I've tried using my Galaxy S3 charger to charge my Note 10.1 just to see if it would work and it shows the charging icon with a line through it (doesn't charge at all).

Any charger will work, but the higher-wattage ones will charge faster. Samsung ones are available all over the place AMZN/FLEABAY/A4C/etc. for cheap (<$10).
My original charger and a supposed duplicate purchased later seem to be charging slower as time goes by. Just as with my last purchase have read a good bit. But I too need advice on the best safe but fast charger and cable. I'm seriously considering the above recommendation for the Anker 40w (8A) 5 port charger. At most I charge only two devices at one time and usually only one. But if this is solid and reliable, the extra ports are ok. Before ordering, several questions:
- I notice the write up states two ports have the IQ charging - is this the case and are they labeled?
- I'd be charging my LG G3 with this too - any issues doing this?
- Lastly, seems cable length/gauge can affect charging speed, right? Which cables are folks having best experience with? I'm considering: http://www.amazon.com/Anker-Premium...ref=lh_ni_t?ie=UTF8&psc=1&smid=A294P4X9EWVXLJ. I prefer long cables if possible...
Bottom line, want a solid charger and cables for my Note 10.1 2014 Edition (and LG G3 if possible) that I won't have to replace in 6-12 months. If there's a two-port of same top quality, let me know too!
Thanks in advance!!

Went ahead and ordered the Anker charger and instead, am trying the http://www.amazon.com/Hi-mobiler-Go...8252875&sr=8-2&keywords=28/24+micro+usb+cable. See it's 28/24AWG hopefully will do the trick...only worried about the gold plating (ones tried before from Amazon seemed to get "lose" their prongs and slip out of my tablet's charging slot). Not sure if it's the gold being softer or ?
In any case, do let me know if anyone thinks the charger would create any issues if used on my LG G3!

All 5 ports are IQ.Charges a Note 10.1 2014, S4, Note 3, Z blue tooth headset and a LG tablet all at the same time and all quickly and fully. Great charger.
I found an issue with the Anker and one of the half a dozen devices of all kind I charged with it.
The touchscreen of my Huawei Tablet acts weird when connected to the Anker. This is a not uncommon thing, but first time i encountered it. And found the reason.
The Anker emits some weak 80v AC current on the GND line. Tested with another brand name charger(One for All, the universal remote maker). That one carried 20 Volts. My previous fav charger also emits AC, like with the Anker, the Texture of the tablet's aluminium case felt rougher during charging, when softly brushing over it with a finger tip. Only there were no touch troubles. Which can be avoided by touching the metal frame with your thumb during tapping the screen.

Is there any concern with this potentially causing damage, or just an inconvenience if plugged in while using the device (if one's unit was emitting that current)?
In my case, I haven't noticed this with either my Note 10.1 or LG G3. My guess is if it hasn't happened after a month or two, I don't need to be overly
concerned - the unit is functioning properly?
Personally, overall been happy with the Anker and haven't noticed any issues...
Thanks!
I had no damage so far, and the Note is happy with the Anker. And it seems that many or most chargers seem affected, like at least three of mine. Probably Samsung's too. Connect a multimeter to Usb 5v ground(the metal shield of the plugs seems to be griunded, though I tested with the plug for my Huawei tablet. Connect the meter's ground probe to something appropiate, like central heating, water pipe or the third line of the mains, which should be "protective ground" or something.
The current only produces a slightly bitter taste on the tongue, near nothing, but it's amazing how the feel of a metal surface changes.
Hello xda members, i have been experiencing a problem on my tablet Samsung Galaxy Note 10.1 (2014 Edition) Android version 4.3 since the past month. It does not charge as usual and a red cross pops up on my battery icon indicating slow charge. I don't know if it's the adapter or usb cable which is causing this, but I tried a set of new charger and cable ( Sony brand ) and still I get the red cross.
What do you advise me to do?
Do i install an app from the store to check if my battery is causing this or do I need to try charging it with a new original adapter and usb cable?
Thank you and awaiting your reply.
The red cross only indicates that the tab is not recieving enough power and even if energy is coming in, it is not enough to charge while using. Understanding this, anything can be cause for the current not being enough:
The adapter could be damaged.
The adapter you are using is not the samsung one and thus is giving less Amperes(Out tab needs 2A and most adapters give 850A-1A).
The cable is damaged.
The cable you are using is not prepared to transport 2A.(This happens to me with the chromecast ones)
The microUSB port on the tablet is damaged. An indicator may be the tablet overheating like crazy when charging but this is not probably because when this happens the device, in most cases, takes energy or not.
I personally find that the cable, if you are using samsung's adapter, is most commonly the problem. Using a cheap cable or a damage cable causes this for most of the tabs I have known.
Hope this helps.

The red cross only indicates that the tab is not recieving enough power and even if energy is coming in, it is not enough to charge while using. Understanding this, anything can be cause for the current not being enough:
The adapter could be damaged.
The adapter you are using is not the samsung one and thus is giving less Amperes(Out tab needs 2A and most adapters give 850A-1A).
The cable is damaged.
The cable you are using is not prepared to transport 2A.(This happens to me with the chromecast ones)

Thanks for replying mate, actually I'm using both original samsung adapter and cable which came in the box.. I will be heading to some shops looking for a Samsung cable and see whether it resolves the problem or not.. What is weird is that sometimes it has the red cross and sometimes it doesn't. Yesterday evening it was slow charging and this evening it was normal charging.

It happened to my brother, he changed cables and changed from light socket and he said he had no more problems; he also may have cleaned the usb that goes into the adapter; ol' "blowing nes carthige" style. I would recommend getting a Q-Tip with alcohol and cleaning every metal part you see in your cables, speacially the 4 metal bands inside the male and female usb port from the adapter and the cable(remember to let it dry before pluggin it again).
BTW, it must be a good cable but it is not necessary for it to be a samsung one. If you have a good phone around and can use that cable, it should be fine(I use a motorola defy one which had a 850mA adapter and it works marvelously; "meh" cellphone but the accesories are darn good), just dont use other adapters because of the Amperage difference.
Also, if you are using any kind of extensions, specially usb port extensions, don't. They are a sure culprit of the problem you are experiencing. I dont know why but these cheap electronics really affect the energy passing through; maybe its the cheap copper or bad solder.
