Hi
I can not charge my Galaxy Player 5.0 from mobile chargers using AA batteries.
Tried several chargers, only one 2AA cheap "noname" is working.
Ayone have the same problem ?
Any ideas ?

You need to look at the output amp rating of these chargers. Chances are the output rating is too low to charge the player. These players came with .75mA chargers and the one you are using is probably kicking out too little of the "juice". Even if it registers, I bet it will take for EVER to even go 5% charged... You need a better charger.

Nope.
Is not charging at all.
SGP 5.0 AC charger is rated .7 A but it can be charged from computer USB ( 5V .5A)
I can get the battery icon to blink with thunder, but is not charging.
Tekkeon is rated 1A and is not charging.
Soshine is rated .4 A and is charging my old LG phone, 0.75A.But not the SGP.
Noname charger from DX, rated .5 A is charging SGP with no problem.
Problem with electronics ?
Anyone ?

Batteries in the charger maybe not powerful enough, just because your LG phones charger has the same output as the SGP charger does not mean they have the same minimum power requirement to charge. remember 2 AA batteries is only 3 Volts and so the charger has a transformer (not the optimus prime kind, lol) that ramps the volt up, the problem is when ramping up voltage your dropping amperage and without knowing the amperage of the double A's your using is impossible to do the math to see if that would give you the min output to charge your SGP.
It's also worth mentioning that those AA chargers are meant to be an EMERGENCY BACKUP and you should NOT use them to regularly charge your devices battery as this method of "charging" and I use that word lightly is very unhealthy for your players battery.

Tekkeon MP1580 problem solved
If you want charge from Tekkeon you have to connect together two center pins inside the USB socket of the unit.

Just curious if there is an app or something similar that would show how many amps are being provided when charging through a wall charger/USB powered hub? The reason I ask is that I'm thinking of buying a powered USB 3.0 Hub. The adapter that came with our phone says it's 2 Amp, so I am assuming our phone can pull 2 amps for charging. Just wanted to verify in some way that a 2 Amp dedicated port would really work for this phone.

When I get home, I'll download the kernel source and see if I can find out how much power it draws during charging. I doubt however, that it will draw 2A during charging as most chargers are rated to supply more power than the phone will accept.
Yeah, 2A seems like that could melt a battery charging that fast. Someone sent me a private message and told me to try CurrentWidget. I threw that on the phone and it registers as 1A while charging. But it appears like the widget doesn't break it down with decimals. For instance it could be charging with 1.8A and wouldn't know it. I put it in a standard USB port and it reported as charging with 0 Amps but the battery was indeed charging.
I took a quick look at the N7100 (International Note 2) source posted on Github by CM and it looks like AC charger is 650mA, USB is 450mA. It's a little hard to tell what exactly it's using for charging, so I'll try to verify that when I get home and have a chance to take a better look.

A 3100mAh Lithium Ion battery can easily handle a full 2A charge rate. The ideal charge profile for Lithium Ion is a CC/CV profile, starts at constant current between like 3V and 4V, which most LI batters can take a rate of 1C, meaning it can handle a charge rate of 3.1A, recommended charge rate to achieve the most possible charge/discharge cycles is usually 0.2C so for a 3100mAh battery that would be 620mA. Once the charge gets to the correct voltage it gets to constant voltage and charges until termination current usually in the 100mA range. So yes, it can handle a 2A charge no problem.
Hey there. I very much appreciate that breakdown. Makes me wonder why they dropped the amps so much during charge.

If this is true (first time I've seen this anywhere), that would line up great with the 650mA max charge rate I found. Also, I downloaded the VZW source, and it doesn't look to significantly different from the N7100 source, at least as far as the charger stuff is concerned, so I would say they both probably have a max charge rate of 650mA.
I appreciate the info and time you both put into this. I guess it means a 2A usb port will be slight overkill. Even changing the charge rate to a higher value seems to indicate a lower battery life. Makes you wonder how apple did it's math for the ipads charge rate. The battery must be huge to accommodate a 1.1A charge rate. Or they are sacrificing battery life for fast charging.
Wont the kernel dictate the charge rate no matter what the charger is rated at?
If the kernel is set for a charge rate of 650mA (0.650A), then why does the Note 2 have a more powerful 2A wall charger, while the GS3 has a 1A wall charger.

The original nook color 7" came with a 2A wall charger and that was 2 years ago... both my note 2 and nook color charge about the same rate (quick to 99% and slow to 100). The charger is probably cheaper to make at 2A rather than anything and plus it could be used to charge future devices. Also if you used a 1A charger to charge the note it might possibly get warm/hot from running at near full capacity.
Im using my OLD blackberry 700mA wall charger to charge the phone at night while im sleeping. No problems with heat.
I dont know whats getting worst.
But whats the best replacement charger for xtz that has a higher amps? I already looked in amazon and most of it has a 2a dual and i still want to ask the community
And guys if possible please suggest those has a long data cable

I cant wait for the next update on XTZ, something like .67
Displa, camera, battery and some tweak, not sure.

I'm not saying it's the best, but I've been using an old iPad charger (2.1A) for the last 2 months without any problems. I plug the charger into a mains extension lead so I don't need a very long USB lead.

Any USB wall wart that is 1.5 amps - 2.1 amps (1500 - 2100 mA) @5 volts will work. The more amps the faster it will charge. In a pinch you could use a 1000 mA charger, it will just take longer.
Alright im confused.. Which is faster mA or A?
And by the way im not asking about the power here but a replacement.
Thanks for the infos though

Congrats, you passed electricity 101.
Keep in mind that batteries can be fickle creatures. Sony delivers the XTZ with a 1500 mA charger. Based on that alone, it's probably best to replace the original charger with another 1500 mA charger. While you can certainly use more than 1500 mA and it will certainly charge faster, in the long run you may end up shortening the battery life. There are only so many charge cycles to be had in any given battery and quick charging can put an extra strain on a battery that wasn't manufactured to suck up power that quickly.
In a pinch, use whatever you have on hand or can find. For everyday charging, its best to default to what the manufacturer recommends.
The Apple 12W one works perfectly fine and charges the tablet so much faster!
There is people here saying it is impossible because of battery electronics.
It's quite simple: They're plain wrong.

Without doubt the best charger I've used for the money. It keeps up with battery drain on heavy use (Full HD video+Net+ others...at the same time) Stock charger does not. At first glance it does seem expensive but does the job very well.
I sent Sony a link to the Apple website for these as it's much better than the POS charger they give you with their £400 "Flagship" tablet. Well worth the £15 price tag.

Well, yes and no. Watts, Amps and Volts are all different measurements for different things and it can be quite confusing to figure out to the uninitiated. Watts is a mathematical calculation based on Ohm's Law. Watts = Volts x Amps
All USB devices accept a maximum of 5 volts. USB standards cap the max power delivered to a device @ 5 volts. Most standard USB ports deliver 5 volts @1 amp. Newer computers and specially designed charging ports can and do deliver more than 1 A via USB but they all deliver a maximum of 5 volts.
12 watts divided by 5 volts = 2.4A
If you look at your charger you'll see the output amps listed as 2.1A or 2100 mA.
Sony's included charger only delivers 1.5A or 1500mA, so yes it charges slower and when the tablet is under high load, has a hard time keeping the battery at 100%.
The real concern here, is what effect does delivering 2.1A of current to the battery day after day have on the useful life expectancy of that battery? I don't know the answer because I don't know anything about the battery that Sony uses. It's possible, if Sony, used a top quality battery, that charging with 2.1A will have no effect at all and Sony just wanted to save a buck or two by including a weaker charger in the box. On the other hand, Sony may have deliberately used a battery designed to accept 1.5A and included an appropriate charger.
As I said in a post above, apart from the battery overheating while charging (if it wasn't designed to charge @ 2.1A) and a reduced useful life of the battery, there shouldn't be any real problem using a "slightly" more powerful charger - up to a point. Charge with too many amps and the battery will probably explode or at the very least melt, potentially causing a fire if left unattended.
When talking to Sony, the question you need to ask, "Is the battery rated for 2.1A or only 1.5A?"

That i can agree with and it's a risk i am willing to take. There is people who say the 2.1A charger wont affect charging time in a positive way at all. That's what what i refered to when i said it's not true.

Definitely. More current (which is what Amps measure) means faster charge times, as long as what is being charged can accept the current being provided. You should be fine, but what do I know. PM me in six months and let me know if your battery still last a reasonable amount of time - then we'll know.

You're kinda right, but kinda not....
The charging circuitry inside the tablet is what regulates the charging current, not the 'charger', it will have min and max currents (the thing we plug into the wall that we all call a charger, is really just a power supply, there's no charging circuitry inside it.) That's why it doesn't charge from a standard usb port (which is 500mA) so, if it's charging faster with a 2.1A power supply, then it's obviously designed to do so.
Let's say, for example, the tab can accept a charging current of between 700mA-2.5A. Obviously, the charge time will be slower at 700mA than 2.5A, however, if you were to plug in a 5A power supply, the charging circuitry in the tablet will still only draw the 2.5A its designed to. So, don't worry about giving it too much, it's not possible.
Now, I don't know what the min and max charge currents are, but I can tell you that mine will charge (very slowly) from a 700mA LG charger.
And also, the dock for the tablet states an input of 1800mA,
So, we can assume the min is at least 700mA and the max is at least 1800.

technaudio,
That's my age showing. Back before some smart guy invented the wheel, we gave a device power and if we gave too much a fuse would blow. I didn't mean to imply that the charging circuit was contained in the wall plug but at the same time, I failed to appreciate that the Tab was designed to prevent an over current situation.
...now let's see what happens when I give this puppy 15A AC...damn, melted the usb cable...

I know there is a thread about what charger to buy, but I have a specs question. Mine z5 came with the International charger and I am in the US. I noted it is 5v and 1.5a. I have a 5v 1a charger on hand. Can I use that?
Sure, it will just take longer to charge.
No lasting negative effects on the battery?

Most certainly no negative effects. In theory it should actually be better for the battery to charge it with less current, but I don't know if that is true.
Different topic: I read that there are multiple versions of the Z5 (US, Europe, ...) and that they support different LTE frequencies. So maybe you want to check if your mobile connection works as intended, if you don't have the US version.
My phone is showing LTE after choosing my apn settings.
I tried using a 5V 1A charger with my phone and it doesnt seem to work. (It works fine on my old phone) The charge light keeps turning on and off. The vibration pulse you hear when it starts charging keeps pulsing too.
Better use an HIGHER amperage, than lower!! Charger will adapte it to phone specifics...A lower amperage will reduce your battery capacity in long time.
I once connected my Z5C to an old 500mA charger (caught the wrong cable) and kept using it a bit (screen on, etc.) and it gave me a nag screen that said that the charger is not suitable because apparently the battery drain from usage was more than what trickled back in.
However, if left alone even a 500mA charger should eventually charge the phone, taking much longer though.
Generally, with chargers, you need to get the voltage right. If the Amperage is higher that what the OEM charger is it does not matter. The electronics in the device limit the charge to what the device can handle. The Amperage on the charger is the max it can deliver. In other words, the charger does not pump 2.5A into the phone forcefully, the phone just nibbles whatever it can take (say 1,5A).

Any reliable source for that? The charging will be slower - yes, but I seriously doubt, that this has negative long-term effects on the capacity.

I think you need a 2A charger to be sure with the Z5c. Most of my older chargers take hours to charge it, and the car USB port (Nissan Qashqai 2015) barely charges it at all.
The UCH20 that came with the phone, takes 2 hours 15 mins to charge the phone fully. I got a quick charger which takes around 1 hour and 10 mins at max
Wow, really?
It is basic electronics. The voltage must be the exact one. Amperage is what the device draws , therefore the charger must be capable to provide a minimum not a maximum.
I repeat, it is basic electronics!
Now a more pertinent question :
What are the voltages for quick charge ? Does anyone know?
If someone has a original charger with quick charge can you please state what voltages are written on it?
Should be 2 or 3 voltages with lowest 5V
Edit : Found myself the info on Sony UK website of a Sony charger.

Download an app like ampere from the playstore and check the charging values with the different chargers. It will more than likely say rapidly charging for anything above 5v 2a charging which is quick charge 2.0 but this device also supports quick charge 3.0

If it's 9v then yes. If it's charging 5v and 2a then its not fast charging like it should.
Check the voltage also.
Basic maths; to get Watts (w) multiple the current (amps) x voltage (v).
So if it is charging at 1.9a like you say it should have a voltage ~9v

It doesn't work like that. Your device has protection built in to avoid overcharging and too much current from frying everything. The max your device will charge is 18w and no more
