AC Adapter - Would this work on my Captivate? - Android Software/Hacking General [Developers Only]

I don't know how this stuff works. So, is that going to charge any phone? I wish I could find an adapter where one cord was white on one side, I thought that was awesome on my Touch Pro.

A micro USB charger is a micro USB charger... they're pretty standard, and yes, it will work. I use an LG wall-wart for my Captivate (or the computer), and have used Blackberry chargers with Motorola products, and vice-versa.

Yup, any Micro USB will work. The only difference in chargers is the amperage at which it charges. The only way that affects the phone is how fast it will charge. The higher the number, the faster it will charge.

I'm buying a charger with this warning:
"This battery charger cannot operate your Micro USB cell phone when attached to a discharged cell phone battery"
What the hell does that mean? I honestly think it is just nonsense.

I have an epic and captivate..and so far only 2 of my micro usb chargers dont charge..both chargers came with bluetooth headsets...
Plus my GF's Droid ONLY and it would ONLY charge with the oem charger that it came with..if she uses the one that it came with my epic the screen will go "crazy"...starts to detects non existing touch inputs, some others wont charge...

Phone Charger

I ordered my Nexus One without a charger and was wondering if I could just use my iPhone USB charger with the supplied USB lead?
I'm guessing that's all the charger is right? Just a charger with a USB port or a miniUSB charger?
all nexus one orders come with a charger. They also come with a usb cable, back-slip carrying case, and a headset.
Not when you want it shipped to the UK.
It adds a charger to the basket so I just deleted it
If it is in the box I'm guessing I will still get the US charger and can just use an adaptor to use in the UK..
Actually I have used the apple iphone charger with usb cables to charge a BlackBerry 8900 and a G1. I would guess it would work for this, but its your phone and your money if you burn it out
yeah youll get a US charger then. In any case all USB chargers are the same. if you have any USB charger with a USB port, you can jsut connect your included USB cable to the charger.

this has micro usb i believe and the charger's you are talking about are all mini-usb. not compatible.
this is not true. the side that connects to the charger itself is still all regular USB. both mini and micro USB cables have the same pinout and electrical output standard.
i know. i'm saying that the end of the cable that plugs into his G1 will NOT FIT into the nexus one because it's MINI USB and the nexus one is MICRO USB.
thats not wat hes asking. hes asking if an iphone wall charger (which simply has a standard USB port on the other end) will work.
Ohhhhhhhhhhhhhh sorry

i think your wrong with the "all usb chargers are the same"
my usb charger (micro usb) for my bluetooth headset will not charge a cliq, it its the same in appearance, but somehow it is actually different
however, the charging cable i had when i had a cliq charged my bluetooth, but I avoided it because it was obvious the 2 chargers where different.

correct. Certain chargers have different amp ratings. For example, GPS chargers generally require higher amount of amperage than cell phones, and certainly a lot more than bluetooth headsets
the g1 charger will not work with the nexus one. I have both phones. The behold II charger will work with a nexus one phone. my gf had the behold ii phone.

You mean plug-wise it won't work right? Because I just took my USB charger, took a Mini-USB to Micro-USB converter and used the G1 charger to charge the N1 and it works.
I'm not sure about the Nexus One but I know on the N900 you could have the problem of that charger not supporting the Data pins(D+ & D-) to communicate with the device and establish a power draw rate, in which case the charger won't work with the phone. The solution was either clipping the data lines in the USB cable, or shorting out the pins in the charger. I doubt the Nexus will be that picky about chargers though.
Usb Charger
Hi,
I just have ordered mine from US. I am from Europe and i will definitely have the problem with the originally supplied charger.
As i am aware all usb ports works with the same voltage - 5V., only amp rate is different. We just need the output amp rate of the original charger and have to be careful not to exceed it. The smaller amp rates are OK (just the charging time will be more.
For example in the originaly stated data from Google says:
"Power and battery
Removable 1400 mAH battery
Charges at 480mA from USB, at 980mA from supplied charger"
Just one to confirm is the original charger amp rate 980mA as Google stated?
I think you'd better to buy a new mobile phone charger for your nexus one for safety.
Just tested plugging the N1 in directly to computer using a miniusb cable w/ microusb adapter and works perfectly. It detected the phone and did that Mount SD notification. I mounted, transfered couple GB of files w/ no interruptions. Also, it charges it like normal.
Usb standard is 5V, most chargers with usb output should be 5V. The Amp is determined by the Voltage and (electrical)resistantce, check Ohm's law.
However the chargers are probably limited to a certain amperage(max amp output). All chargers I've seen have inscripted input and output values, as long as output values are within usb standards it should be ok.
I have an iphone car charger with usb out. It stays in the car and charges my family's gadgets no mather the manufacturer/type of device, as long as it supports usb charging.
So theoreticaly it should work. To be safe check the output values on the usb charger.
If n1 came with the american charger you can check the output values of that against the iphone charger output values.
Would a simple US 2-pin to UK 3-pin plug adaptor be fine?
The few gadgets I've got with US plugs I would just buy a UK version plug but since you cant just buy these in any shops (yet) will just have to wait and see what they supply first.
Anyone here with the US charger could you post the output values please

Ordered 3 chargers off of ebay, none work

Ordered a universal one with wall attachment and car attachment and when I connect the USB to microUSB cord the phone doesn't charge. Ordered another stand alone car charger and it, also, doesn't charge. If I attach the USB cord that came with the phone to the wall/car charger it charges fine. Both, specifically said for the "Nexus One". Is it an amp issue? Most microUSB charger in the mall cell phone kiosks won't charge it either. Is it a proprietary microUSB cord that I need or a matter of amps or something?
Why not buy from Monoprice.com?!
I ordered 8 USB cords (2/each of 4 different lengths), 2 Car Chargers, and 2 Wall chargers. All work perfectly fine, and I paid under $25. (Wife has a CLIQ, so we got plenty to work for both of us.)
So, I don't know what your issue is... Other than just not going to Monoprice

well I havent ordered from monoprice since customers got slammed with bogus charges... i guess i could give them another try though, but still... kinda weary
Why? I had over $1300 attempted to be spent at Newegg, and my CC company called me and stopped the charges. Got a new CC in the mail the following day. Some random amount at Apple as well. LOL. Fun times.
(Yes, it happened to me. I'm fairly confident it was from the same issue as others..) But, that doesn't stop me from using a company that makes good products, expecially when they just made such a big mistake. Odds are, it won't be happening again for a long while
Either way... Those are risks with online shopping. You just have to make sure that your method of purchase has fail-safes.
I have a CRAP load of mini USB chargers (all HTC stock) and didn't want to buy more. I bought a bunch of Motorola mini to micro adapters off Overstock.com for $2 a piece and couldn't be happier. I also bought the official Google cradle to avoid additional wear and tear on the microUSB port.

I bought a car/home charger from eBay when I had my Motorola Cliq, and my home charger would keep going on/off charging. I later found out that it was the voltage issue, where the charger was giving a maximum of 5 amps and the Motorola Cliq needed 5.1V or something like that.
But most chargers I've bought don't power the Nexus One. What specific voltage or amps should I look for it to have? The two I bought off of eBay specifically said they were for the Nexus One. Neither worked. Sellers are putting any micro SD chargers up for sale assuming they will change the phone. They will not. What technical spec will tell me if it really will charge it?
Could someone post a link to a USB charger that absolutely works? I just bought another one from Best Buy that doesn't charge the Nexus. Made by Rocketfish and is suppose to be universal.
Thats really wierd. Every charger i've tried works fine.
You're charger should be outputting 5V and anywhere from 300mA upwards. There is no max mA limit because the phone will only draw what it needs.
This might sound patronising, and I really dont mean it to, but when you say doesnt charge how do you know?
Do you mean from totally flat it won't turn the phone on and start charging it, or do you mean when the phone is on the battery indicator doesnt show a charging, and the LED doesnt go orange/green?
Or do you mean it never charges to full?
When I plug it in it's as if nothing happens. No light, no thunderbolt symbol on the battery, no screen wake-up, nothing. Nada. Now, the HTC wall charger and usb charger work fine. But if a MicroUSB charger calls itself "universal" it does not mean it will charge the Nexus. The HTC HD2 charger my wife has works fine on the Nexus though.
Hmm strange.
The charge process works like this:
- Charger plugged in causes voltage change on +ve USB line - potential charger detected.
- Phone draws minimal current (50 to 100mA) and tries to negotiate USB power
-- If that suceeds it tries to increase power to 500mA if the USB port supports it. If yes charging starts at 500mA, if not charging starts at 100mA
- If USB negotiation fails, it checks if D+/D- are bridged.
-- If D+/D- are bridged, the phone draws as much current as it can/needs
-- If D+/D- are not bridged, the phone draws a max of 500mA
There's nothing special about the chargers unless they have been wired in some special way for a specific phone. Thats why I'm very surprised these chargers dont work.
I know that if I chop a USB extention cable and cut out D+/D-, my nexus charges at 500mA. I've tried this myself for a totally different purpose. Thats no different to ground and power being wired to a 5v source.
Odd, I have three car USB adaptors and two AC USB adaptors.. All charged the phone, although only the AC charger shipped with the Nexus would do a fast charge, and none of my car chargers would. I found one that was rated 1Ah and soldered the two middle pins, now it works as a fast charger too.
The Motorola P513 car charger (OEM designed for a Droid) gives out 950mA, is super cheap (~$3+shipping), and works great for a fast charge with the Nexus One.

Thank you sir. I've been trying to find a car charger that guarantees a fast charge.
Just ordered one from Play.com for £3.99 w/ free shipping.
Maybe now I can use GPS for more than an hour...
I dunno.
My motorola charger for my old bluetooth (H780?) works fine, as well as the original google charger. I also have a car charger for my old bluetooth as well.
My suggestion, is to only buy name brand chargers?

Can charger be used with other phones?

My charger that came with the SGS4G is not an official Samsung one. This is because I bought my phone used and it came with a 3rd party charger.
The charger is just a one-piece charger. I cannot remove the cable. It says:
AC Charger
Model: Micro USB
INPUT: AC 90V-240V
OUTPUT: DC 4V-8V
Can I use this charger with other phones that charge over MicroUSB? Do I need to make sure the other phone can handle 4V-8V?
Also I intend to buy another charger as backup, but I have this adapter which I plug in my USB cable into and then it goes to the power outlet. When I used this, my phone acted very erratic, swipes would not register correctly, phone became unstable, etc. Any reason for why this would happen?
It's sounds like your generic USB charger, and should charge anything that would charge if you were to plug it into a computer's usb port. I have a belkin usb plug, except it has a usb port on it instead of a cable, and it charges everything, even PS3 controllers lol.
Who makes this charger? If it's a super cheapo, the power may be dirty and may cause your phone to act funny.

Yes and yes to the first two questions but it normally isn't a problem depending on what is charging.
To the third, I had that same problem with my ZuneHD and a generic manufacturer's cable and I still don't know why.
Sent from my SGH-T959V using XDA App
The major issue is "are the data lines shorted together?". If they are not, your phone (and other devices that use USB for power) will see it as a simple USB port and limit draw to what a PC USB port can supply (not much).
There are also some ways (particular resistors used across... pins 1 and 3?) to indicate how high the charger can go.
Most of the USB car chargers (at least the ones with USB ports) do NOT do this, so they take forever to charge a phone.
Easiest way to tell: with the charger charging, go into device settings. If it says "Charging(AC)" you're good; "Charging(USB)" not so good.

[Q] Sidekick 4g doesn't charge via wall, but very slow via usb to pc

Sidekick 4g will not charge via wall, but does charge very slow on usb. I tried different wall chargers except the "official" wall charger, even a samsung branded usb detachable wall charger, but it still keeps doing in and out with a beep sound and doesn't charge. Am I missing something??? Please help, this issue is extremely aggravating especially when you use your phone for business. X(
I am on the final smooth maximus rom btw.
Well in my experiance with samsung phones and even some htc modles you have to use an offically branded charger for your modle sometimes, it has to do with the pins and how they line up, now if you use the usb cored and a travle wall charger (I use this set up in my truck for work) you should see a faster charge time cause the voltage is higher and its the right pin set
Sent from my SGH-T839 using XDA App
The connector is an industry standard. There's no problem with the pins not lining up. There's also no difference in voltage between chargers. Being USB, it has to be 5v.
However, some chargers have higher capacity than others. The USB spec allows for 500mA from a PC's USB port, but chargers sometimes increase it to a full amp for faster charging. The phones will still charge from a PC's USB port, but they'll take longer.
Also, some companies (Like Motorola) require a special Motorola-branded charger. It's just because they want to sell more chargers. The only difference between a real Motorola one and a generic one is a resistor between two pins to identify it to the phone.
The Sidekick doesn't have this vendor lock-in crap. It'll charge from just about anything you can plug it into. If it's not charging I'd suspect a broken USB connector on the phone, a faulty battery, or a damaged charging circuit inside the phone.

Thanks for the response guys.. Yeah, this stuff is pretty weird.. it would blow if the port is messed up. The phone is brand new though, would they be manufactured faulty?? In that case samsung tech department sucks!
When you make a million of something, statistics say that a few mistakes will happen. If it's new I'd suggest taking it back. I charge my Sidekick off of my PC's USB port and am often surprised by how quickly it charges.

Apple Charger

Anyone attempt to use an iPad charger with the Tab S? I always travel with it and just pack a micro USB cable since it has high output. Just attempted to plug in my 10.5 to it and nothing. Luckily I was able to track down a different charger, and it worked fine with the same cable. This is the first device I've had that refused to charge using my iPad charger. What gives?
Mine won't charge that method either. (ipad air plug)
I think the Tab S is very picky, with some other chargers, i get the lightning indicator in the battery with a red cross on top, is this the same with you.
Yeah, mine's a little picky too. It won't charge off the Motorola micro usb chargers we have all over the place at work, but it will charge off just about any USB plug and cable I throw at it. Also charges off the USB ports in the plug strip in the living room.

Do you get the red cross on top of that battery indicator.
There is a standard for high current usb chargers (rather than pc usb ports) that is indicated by having the data lines shorted together, as far as I understand it the iPad charger uses a different system to indicate high charge ability. (I'm assuming) the Samsung charger has these pins shorted internally and uses a plain cable (which can also be used for pc data connection).
You can get the high charge rate from a standard charger by using a cable with the data lines sorted, either make your own or buy a ready made one (e.g. Portapow or their plug-in inline adapter). I'd guess that the same cable would also get full charge via the iPad charger, these cables though cannot be used to connect to pc for data.
Samsung dedicated chargers
Apple and Samsung both use their own unique standards for USB charging so their devices know when they are connected to a charger capable of supplying the higher current they prefer. They do this by using a resistor voltage devider inside the charger to apply a very specific voltage to the data leads of the USB cable.
A little Googling will find examples and descriptions of the Samsung design.
There is a little plug-in, intelligent, USB adapter available that will interface Apple and Samsung devices to any charger. It senses what device you have and supplies the correct voltages on the data leads so your device thinks it's plugged into its official cherger. I think I saw it on ebay.
Edit- here is the adapter to allow using any charger with Samsung or Apple devices.

Just keep in mind that this adapter will make your tablet believe it's connected to a charger that can supply high current. If the charger cannot supply high current, it will be overloaded and it's output voltage will sag.
I don't think this will damage the Samsung tablet, but it will slow down charging and may overheat the charger.

Maybe I'm a conspiracy theorist, but I was also unable to charge the tablet with my wife's macbook using the same cable that works fine with other wall chargers. I am pretty sure it worked fine when it was booted into bootcamp as well...
She's in Europe for a few months so I won't be able to confirm for a while.

The only charger I've used with my Tab S 10.5 is this one- http://www.amazon.com/gp/product/B00DVH62J2/ref=oh_details_o08_s00_i01?ie=UTF8&psc=1
I haven't even tried the factory charger yet. I'll have to test it and see if the Tab S uses the same voltage sensing on the data leads as the previous Samsung tablets.
I've been using an Ipad 10w charger,fat,square,.twice the weight of the OEM Samsung charger ,removable prongs.
It WORKS WELL. Where my Samsung OEM charger has trouble charging
when the tablet is in use, the fat Apple charger kept charging at a good speed.
A bit warm as compared to OEM Samsung charger but not "Hot".
Probably 20% + faster charging as its very noticeable (except 99 to 100 % takes a while, charging rate software?)
I'm using an original Apple charger at work to charge my 8.4. I don't know if the charger is for an iPhone or iPad. Someone left it at work. I gave away the lightning cable that came with it since I don't own an Apple product. The cable I'm using is part of an LG qi charger (doesn't come with a wall adapter/charger).
